artificial sand - what is it and how to make it | fote machinery

Artificial sand, also called crushed sand or mechanical sand (m sand), refers to rocks, mine tailings or industrial waste granules with a particle size of less than 4.75 mm. It is processed by mechanical crushing and sieving.

In China, the artificial sand was mainly used in the construction of hydropower systems. For example, the Three Gorges Project and the Yellow River Xiaolangdi Project used artificial sand to prepare concrete. Due to the remote environment of the hydropower project and the high quality of sand and gravel, the projects have taken the materials locally.

Many Indian states have decreed the use of crushed sand in infrastructure construction because of its high compressive strength and cohesion and the adverse environmental effects of river sand mining, which will greatly boost the demand for artificial sand.

There are both natural and human factors in the increasing demand for artificial sand. The former is that the natural sand is about to run out, while human factors include people's requirements for environmental protection and the need for high-quality concrete.

With the development of infrastructure, the natural sand resources formed by hundreds of thousands of years in many countries and regions have been almost exhausted, which has affected the further development of construction projects.

Driven by huge interests, natural sand has been indiscriminately mining, which changes the river course, affects the safety of river embankments, destroys the living environment of fish and contaminates the groundwater. The crushed stone sand is an important alternative resource to change this phenomenon.

In the process of mining river sand, it often produces a large amount of tailings which is not used reasonably. Especially in small mines, the tailings are piled up at random, occupying land and polluting the environment.

Besides, in urban planning and construction, a large amount of construction waste is generated, which actually can be crushed by the crushers to produce the artificial sand and aggregates for promoting resource utilization.

With the rapid development of concrete technology, the comprehensive performance of high-performance concrete and high-strength structural concrete has higher requirements on the quality of aggregates, requiring it with stable quality, good gradation and shape, while less and less natural sand meets the requirements. Therefore, people are turning their focus on artificial sand.

Artificial sand and mixed sand are mainly used in building construction, municipal construction, transportation, and other projects whose concrete strength grade is below C60. When meeting the corresponding technical requirements, they can also be used for concrete projects such as ports and water conservancy.

The vibrating feeder feeds the stone evenly into the coarse crushing machines for the primary crushing of the stone. The crushed stone from the coarse crushing equipment is transported through the belt conveyor to the fine crushing machines for the secondary crushing.

The primary crushing equipment directly processes supplied materials from the stone material factory and is the foremost processing plant. The jaw crusher is the ideal choice for primary crushing.

The secondary crushing equipment is responsible for the middle and fine crushing in the stone crushing process. The secondary crushing equipment mainly includes impact crushers and cone crushers.

The crushed material is conveyed by the belt conveyor to the crushed sand making machine for fine crushing. The finely crushed material is then screened through the vibrating screen for coarse sand, medium sand, fine sand and other specifications.

VSI sand making machine is called high cost-effective sand making equipment with low initial investment cost and good use effect. It is high in operation efficiency with the PLST crushing cavity.

The HVI sand making machine manufactured by Fote is more advanced in technology. Its butt ends and lubrication scheme are modular in design, and the peripheral guard plate can be turned up and down to extend its life cycle. It has the effects of sand making and shaping at the same time.

For those with strict requirements on the powder content of sand, a sand washing machine can be installed behind the sand manufacturing machine, and the sewage discharged from the sand washing machine can be recycled by the fine sand recovery plant.

The following video shows clearly the difference between crushed sand and river sand from the aspects of source, wastage, setting time, shape, silt content and so on. It is worth collecting and sharing with friends.

The table below shows the mix ratio of M15 M55 and M55 M55 concrete designed for artificial sand and river sand. The results show that in the same Concrete Mix Design, the strength of concrete by artificial sand is higher.

As the demand for aggregates from China, Africa, Latin America, Europe,etc. will continue to rise, and the price of artificial sand will also increase, the outlook for the global aggregate market for sand and gravel is worth looking forward to.

According to the Global Sandstone Aggregate report, by 2020, the demand for aggregates of sand and gravel in the Asia-Pacific region will increase the fastest in the world, and the growth rate of India, Vietnam, Malaysia, Indonesia and other regions will be among the best.

Due to the economic transformation, the demand for sand and gravel aggregates in China will slow down. However, the report predicts that by 2020, China will still be the world's largest aggregate demander, accounting for almost half of the world's total aggregate.

The Global Sandstone Aggregate report shows that the reserves of natural sand are gradually decreasing globally, and in some developing countries where the demand for aggregates and sand is huge, illegal sand mining has happened frequently. According to the report, by 2020, the reserves of natural sand resources in some countries will be quickly depleted.

The depletion of natural sand resources will lead to a sharp increase in the price of aggregates and artificial sand, especially in areas where the demand for aggregates is huge. It can be seen that the profit margin of the artificial sand is very large.

The m sand manufacturing machine produced by the supplier Fote is suitable for m sand making production line of high hard and abrasion-resistant materials such as limestone, quartz stone, granite, river pebble, basalt, cement, various ores, glass raw materials, mechanism building stone, gold slag, etc.

The limestone, widely distributed in nature, is easy to obtain. It is the main raw material for manufacturing cement, lime and calcium carbide. After being processed, limestone is used in large quantities as building materials. Generally, simple processing process is through the limestone sand production line.

Quartz is a hard, wear-resistant, chemically stable silicate mineral mainly composed of silicon dioxide. It is an important industrial mineral raw material generally used in glass, building materials, ceramics, high-tech electronics industry, etc. after crushing and sand making.

The granite has the characteristics of hard texture, high strength, abrasion resistance and weathering resistance. It has the title of "The King of Rocks" and is a good building material. It is rich in resources with low mining costs but high product value. Granite is a popular choice when the product needs to be weather-resistant or durable.

The river pebble resources are rich with low collection costs and high application value. After making sand from river pebble, it is widely used in water conservancy and hydropower, expressways, high-speed railways, passenger dedicated lines, bridges, airport runways, municipal engineering and high-rise buildings in the engineering field.

Basalt is the best material used for repairing roads, railways and airport runways. With the characteristics of strong compressive resistance, low crushing value and strong corrosion-resistance, it is the best cornerstone for the development of railway transport and road transport.

what are the differences between artificial sand and natural sand? | hxjq

Since the amount of sand making machine is falling and more and more policies are set to protect the natural sand, the market for artificial sand (that is, sand and gravel aggregates processed by industrial sand making machines such as sand making machines and impact crushers) has shown great potential and vitality.

The artificial sand produced by the high-efficiency sand making machine has gradually replaced other machines in the market with its unique advantages and has become one of the main sources of building materials.

Sea sand often contains shells and other impurities, and its components such as the chlorine, sulfate and magnesium salts may cause corrosion of steel bars. All the components will affect the performance of concrete.

The main technical indicators of artificial sand are particle gradation, fineness modulus, stone powder content, void ratio, apparent density, bulk density, methylene blue value (MB), crushing value index, mica content, light-matter content, etc.

Due to years of exploitation, natural sand has become less and less. With soaring prices, the supply and quality of natural sand are not guaranteed. However, there are too many artificial sand resources. And it can produce artificial sand as long as there is stone. Urban construction waste, gravel tailings, stone chips, gravel, and mine tailings can be used as artificial sand raw materials.

The price of artificial sand varies from place to place, but it is basically much cheaper than river sand. Compared with river sand, artificial sand is about $3 per ton cheaper. In addition, the profit of the artificial sand is quite considerable. Based on the current market price of 2,000 tons per day, the estimated gross profit per month is more than 150,000 US dollars.

The traditional artificial sand production will bring environmental problems such as dust pollution. However, with the continuous improvement of the sand making process, the production now adopts a fully enclosed structure, and each machine has a water spray setting which prevents the dust from overflowing.

The arbitrary exploitation of natural river sand will change the shape of the bottom surface of the river bed, and then change the water flow direction, which will form complex flow modes such as vortex and reflow. These phenomena will further affect riverbeds, dams and river sandbars in a wider range by affecting the accumulation of sediments or causing sediments to be eroded, thus affecting river dike safety, bridge safety, and navigation safety.

The solid performance of the artificial sand is slightly worse than that of the river sand, but it still can meet the international sand standard. However, for the construction that is often subjected to frictional impact, the lime-sand ratio of the concrete, the crushing index and the stone powder content of the sand should be controlled.

Stone powder refers to the materials with a particle size of less than 75m mixed in the artificial sand. Generally, ordinary concrete requires less than 10% of stone powder, and high-strength concrete requires less than 5%.

Through the cement, mortar, and concrete test, there is no difference between the artificial and the natural sand. Generally speaking, the water consumption of artificial sand is slightly larger. However, the strength of concrete is basically unchanged.

The graininess of the artificial sand is more irregular. When it is bonded with building materials such as cement, it tends to have better adhesion, more compression resistance and longer service life.

According to surveys conducted by foreign professional research institutions, the global sand and aggregate market demand will reach 51.7 billion metric tons in 2019, with an average annual growth rate of 5.2%.

In the future, the estate industry in developed countries will recover, and the rise in per capita wages in developing countries will also stimulate peoples demand for modern housing. In terms of infrastructure, national investment and commercial investment will also be exerted at the same time.

In addition, according to the report, the storage of natural sand is gradually decreasing globally, and in some developing countries where sandstone aggregates are in great demand, the exploitation of natural sand has been prohibited by law.

The report shows that by 2019, natural sand reserves in some countries will be quickly depleted. The depletion of natural sand resources will lead to a sharp increase in the demand and price of artificial sand, so in the future, artificial sand production will be a good investment choice.

That is: the sand making process is that big stones are crushed coarsely by the jaw crusher, and sent to the impact crusher or the cone crusher for further crushing, and then the material is delivered to the sand making machine by the belt conveyor.

The wearing parts which are made of different materials have different wear-resistance ability. Wearing parts made of wear-resistant materials not only helps us save the replacement time, but also saves a lot of purchase costs.

Purchasing ability is one of the most important conditions when selecting equipment. When selecting a machine, please consider all the equipment conditions, and then combine with the cost to select the machine that suits you best.

Under the condition of natural sand depletion, the occurrence of artificial sand has alleviated this phenomenon in time. Through the above comparison, it is found that the artificial sand can be used as a good substitute for natural sand in infrastructure construction.

On the one hand, its own characteristics can meet the standards for construction. On the other hand, various ores such as limestone, basalt, quartz, andesite are widely distributed around the world. Many mines are still to be developed and utilized, so the artificial sand is a good investment market.

If you want to buy artificial sand production equipment, please consult the HXJQ Mining Machinery, our professional engineers will design the best artificial sand production line according to your specific needs, to help you choose the most suitable production equipment.

sand cloud review: the best sand-free beach towel for 2021 | hgtv

sand cloud review: the best sand-free beach towel for 2021 | hgtv

Summer is looming in the distance. And while theres plenty to love about this season longer days, warm nights and afternoons spent by the water summer also ushers in another season thats not so sunny: Soggy Towel Season.

You can find evidence of Soggy Towel Seasons reckoning across patio railings, towel racks and shower doors all summer long. If you listen carefully, you can almost hear the deep sigh of a woeful beachgoer whose towel from yesterday still isnt dry. And dont even get me started on the sand, forever clinging to that damp towel that is, until its time to toss it into your bag. Then youll suddenly have enough sand to build a sandcastle inside your suitcase.

In a frenzied effort to avoid Soggy Towel Season at all costs, I eventually stumbled upon Sand Cloud towels. Founded in San Diego and featured on Shark Tank, Sand Cloud boasts stylish, Turkish cotton towels in a variety of sizes, colors and patterns that claim to be sand-resistant, quick-drying and larger than a standard towel, all while still being thin enough to fold up comfortably into your bag.

Even with the Shark Tank seal of approval and hundreds of positive reviews, I was skeptical: Could a beach towel really be that good? I put Sand Clouds XL beach towel and one of their bath bundles to the test over the course of a month to see if they stood up to the hype.

Sand Clouds XL towel measures approximately 60 x 68 inches. The one I received was in the Boho Turquoise pattern, a bright blue (it's actually more vibrant than it appears on their website) with organic shapes. The XL towels feature tassel fringe along the shorter sides.

The Sand Cloud XL towel is sand-resistant, quick-drying and folds up easily into any bag. Coming in a rainbow of hues and patterns, the 60" x 68" towel is made from soft, organic Turkish cotton and comfortably seats 2-3 people. Sand Cloud donates 10 percent of its profits toward marine conservation.

Sand Clouds bath bundles come with two bath towels and two hand towels. The bath towels measure approximately 35 x 60 while the hand towels measure approximately 18 x 28. I received mine in gray but they also offer the bundle in navy, and, according to their website, more colors are on the way.

The Sand Cloud bath bundle includes two bath towels and two hand towels made from soft, organic cotton. The lightweight towels dry quickly and are thinner than a traditional bath towel, making them just as good for frequent handwashing as they are for tossing into a bag for an afternoon by the pool.

All the towels are made from organic Turkish cotton. The XL towel is especially soft to the touch its not surprising that many of Sand Clouds marketing photos feature people looking off into the sunset with the towels draped around them. You could easily use the XL towel as a blanket in a pinch or while camping.

The bath and hand towels are double-sided, with one side being flat woven and the other looped terry like you would expect from any other towel. However, if youre used to a thick, plush towel, it will take some time for you to adjust to the thinner Sand Cloud towel.

The washing instructions state to machine wash the towels in cold water. The XL towel stayed soft on its first run through the wash; the bath and hand towels felt a bit stiff but did soften up after a few washes. The XL towel states to air dry it, while the bath bundle items you can toss in the dryer in a low-heat cycle. I have no room to air dry the XL large towel, so it goes into the dryer as well and doesnt seem to be fraying or getting destroyed just yet.

The first thing youll notice is just how thin these towels are. You can stack two, or even three, of Sand Clouds bath towels before reaching the thickness of one standard towel; in addition, the bath towels are bigger than a standard bath towel, meaning you can really, truly wrap the towel all the way around yourself after a nice shower.

Sand Cloud towels are thinner and use less fabric, but are still the same size or sometimes even larger in length and width as a traditional towel. This makes them both space-saving and more eco-friendly, since not as much material is needed to create each towel.

Even the most intricately folded, standard bath towel still takes up more room than the XL towel. The XL towel replaced a large, woven blanket that I would have to tie up like a yoga mat and shove between the straps of my backpack to carry to the park, turning me into a human bumper car every weekend. Thankfully for me and other parkgoers, you can easily fit two of the XL large towels into a large backpack or beach bag (even if they were folded poorly and hastily shoved into your bag) and still have room for other items.

Upon hearing I was testing Sand Cloud towels, two friends bought XL towels on their own accord for an upcoming beach trip, which led to lots of jokes that the beach would offer more scenic views of our oversized towels instead of the shore. Once you lay them down, though, I think youll find theyre a perfect size: two adults can comfortably lounge on one of the XL large towels while still fitting your bag on its surface. We even used the tassels to tie the ends of the towels together to help keep the corners weighed down on a windy beach day.

If you need more room, Sand Cloud offers an even larger towel option, aptly named the Party Blanket that measures around 83 x 87, though their website says that due to its four-layer weave design, it may slightly shrink after a few washes.

Coming in at 83" x 87", the appropriately-named Party Blanket features the same qualities as Sand Cloud's other towels quick-drying, sand-resistant and thin enough to fold easily into a backpack in a size that can fit you and all your friends.

Before I knew Id be able to go to the beach, I took the XL towel to the sandiest place in the city I knew: a volleyball court in the park. After fussing with it in the sand for several minutes for the purpose of this photo, I actually was pretty impressed that the sand did seem to shake right off. The towel is going to see park lawns pretty frequently, so Im happy to report that the towel also shook off bits of dirt, hay and grass that normally would have stuck to my old towel and ended up all over my floors. editor Jessica Yonker took an XL Sand Cloud beach towel to the test at her local park. Sand Cloud towels are quick-drying, sand- and grime-resistant and fold up easily into any bag or backpack.

The real test was a long, windy day at the beach nearly a month later, when my towel basically got buried in the sand from frequent roundtrips to the ocean back to the towel, accidentally getting stepped on and when we buried my friend in the sand right next to it. And though it needed a little more force, the sand really did glide off it.

As Im sure is clear now, wet towels gross me out. Thankfully, the hand and bath towels really do dry quickly. The hand towels dry up between rounds of what feels like constant handwashing these days. My bathroom is dark and doesnt get any natural light, and I can still return to a semi-dry towel.

On my beach trip, we hung the XL towels across the deck railing to dry on a sunny day; when we went back outside about an hour later, the towels were already dry. In fact, they were almost completely dry. Im used to having to carry my wet towel back in a separate bag to not get my other belongings wet, but this, helped by its compact size, isnt necessary with the Sand Cloud towel.

Another fun beach anecdote that speaks to Sand Clouds water resistance: We accidentally spilled a full drink and were blown away to see the liquid actually beaded up onto the surface of the towel, and we were able to pour the liquid right off of the towel.

Farewell, Soggy Towel Season. Sand Cloud lives up to its boasted features, and Im looking forward to taking my towels on more beach vacations, picnics and eventually festivals and camping. I honestly didn't think that I would have so much to say about a set of towels. If youve made it this far and still arent sold, dont take it from me, just listen to my friends unsolicited commentary overheard throughout our beach trip:

difference between m sand vs river sand | what is m-sand & river sand

difference between m sand vs river sand | what is m-sand & river sand

M Sandis nothing but artificialsandmade from crushing of rock or granite for construction purposes in cement or concrete.M sanddiffers from natural riversandin its physical and mineralogical properties.

In some case studies, it was found that concrete produced by using manufactured sand obtained 6-9 %(percent) higher compressive strength and 12-15 %(percent) higher flexural strength compared to river sand of the same grade.

If I am not mistaken, P sandstands for Plasteringsand. Other types are manufacturedsand(msand), sharpsands, buildingssands etc. The difference is in the size of the particles. Plastering sandwill have fine grained particles, whereas manufacturedsand will have little coarser particles may be.

Manufactured sand(MSand) is artificialsand produced from crushing hard stones into small sand sized angular shaped particles, washed and finely graded to be used as construction aggregate. It is a superior alternative to RiverSandfor construction purpose.

MSandis the only alternative toriver sand. Higher concrete strength comparedtoriver sandused for concreting. ThoughM Sanduses natural coarse aggregates to form, it causes less damage to the environment ascomparedtoriver sand. Better quality control since manufactured in a controlled environment.

Concrete withm sandhas very poor permeability as compared toriver sand. But whenriver sandis used in concrete the permeability of concrete is less poor as compared toriver sand. It has more water absorption 2 to 4 %. Whereas water absorption ofriver sandis less 1.5 to 3%.

Manufactured sand(MSand) is a substitute of riversand for concrete construction.Manufactured sandis produced from hard granite stone by crushing. The crushedsand is of cubical shape with grounded edges, washed and graded to as a construction material.
