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

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.

quarry crusher machine

quarry crusher machine

Quarry crusher refers to large pieces of ores overcome internal force between the molecules and then be crushed relying on effect of external force, which is also a process of making granularity of ore block narrow gradually. In the ore crushing plant , ore smashing is generally divided into coarse phrase and fine phrase. In the quarry crushing plant, stone crushing is necessary material preparation phrase before sorting operation.

Firstly, the ores to be processed by ore dressing plant are mostly tied together with valuable minerals and gangue mineral. Only by crushing and dissociating them can we use existing physical separation methods to enrich them. Secondly, all of physical separation methods are restricted by granularity, too coarse or too fine granularity cannot be separated effectively.In every link of quarry crushing plant, quarry crusher is both the most expensive process and important part of constituting investment and production cost of ore dressing plant.

In conclusion, basis task of quarry crushing is to provide suitable materials for sorting operation. Quality of quarry crusher work directly affects ore dressing technology and economic indicators. Hence, some people think that quarry crusher machine is the key to determine success or failure of ore production line. Therefore, the ore beneficiation plant should pay enough attention to selection of processing equipment and production management of ore crushing work.

the 5 most useful methods of lithium mining beneficiation - jxsc

the 5 most useful methods of lithium mining beneficiation - jxsc

Lithium is an important strategic resource widely used in emerging fields such as batteries, ceramics, glass, aluminum, lubricants, refrigerants, nuclear industry and optoelectronics. It is an indispensable and important raw material for modern high-tech products.

Chile, China, and Argentina all have rich reserves of lithium, but they are all eclipsed by the Salar de Uyuni in Bolivia, South America. According to the US Geological Survey, the lithium reserves under the Uyuni salt marsh are staggering, accounting for almost half of the worlds lithium. If the lithium mine resources are fully developed, Bolivia, a poor South American country, will rival the Middle East giant Saudi Arabia.

From the perspective of the changes in the various uses of lithium in recent years, the battery has become the first largest application field in terms of the growth rate of lithium in other fields. At present, the global demand for lithium carbonate is around 140,000 tons. It is expected that the global demand for lithium carbonate will maintain an average annual growth rate of 15% to 20%, driven by the growth in demand for global consumer electronics and new energy vehicles. The annual consumption will reach more than 300,000 tons, and the proportion of new energy vehicles to lithium carbonate will increase from 9.7% in 2012 to 37.8% in 2018. If the global new energy vehicles, especially the pure electric vehicles represented by the US Tesla, grow faster, the global demand for lithium carbonate will reach 350,000 tons by 2010. As for the supply of lithium carbonate, there will be a gap in the supply and demand of global lithium carbonate by 2019.

The hand selection method is a sorting method based on the difference in color and appearance between lithium minerals and gangue minerals. The selective particle size is generally 10 to 25 mm, and the determination of the lower limit of the particle size depends on economic benefits. Hand selection is the earliest method of mineral processing used in the history of lithium mine production. In addition to spodumene, the hand selection is also used to pick lithium concentrates from lithionite, petalite, and amblygonite.

1 The positive flotation that is preferential flotation of spodumene, the working principle: ground fine ore in an alkaline medium formed by sodium hydroxide or sodium carbonate, after high concentration, strong agitation and multiple washing and de-sludge, the fatty acid or its soap is added as a collector to directly float the spodumene.

2 The reverse flotation process is to inhibit the spodumene in a lime-adjusted alkaline medium with dextrin and starch as a regulator, and use a cationic collector to float the silicate-like gangue mineral as a foam, and the product in the tank is It is a spodumene concentrate.

Hand selection and flotation are the main methods for selecting spodumene. Other methods such as thermal cracking, magnetic separation and gravity separation play an auxiliary role in the production of spodumene concentrate.

Working principle When the natural spodumene is about 1100 C, its crystals change from type to type, and at the same time, the volume expands and easily breaks into powder. Through grinding and screening producers, can achieve separation of spodumene and gangue minerals.

Since the difference in density between spodumene and associated gangue minerals is not large, gravity separation methods such as jigging, spiral beneficiation and shaker beneficiation are not suitable for the process of spodumene ore. However, heavy medium separation or heavy liquid beneficiation is an effective method for spodumene ore. Heavy medium separation method has been used in the production of lithium mines in South Dakota and North Carolina.

Magnetic separation is often used as an auxiliary method to improve the concentrate quality of spodumene. For example, the spodumene concentrate produced by the flotation of North Carolina, USA, is high in iron and can only be sold as a chemical grade concentrate. In order to meet the requirements of the ceramic industry, the plant uses magnetic separation to remove iron. In addition, since iron-lithium mica has weak magnetic properties, magnetic separation can be used as the main method for producing iron-lithium mica concentrate.

sand and gravel prospect and price in philippines | hxjq

sand and gravel prospect and price in philippines | hxjq

Background: The Philippines is located in the center of Asia and has historically been the center of regional and global trade. Compared with other old ASEAN members, the Philippines is relatively backward in infrastructure.

Sand and gravel resources have been one of the outstanding advantages of the Philippines compared with other Southeast Asian countries. And since 2017, the sand and gravel prices in the Philippines have kept rising, and sand and gravel industry has become one of the most promising industries in the Philippines.

The Philippines, ASEAN's fastest-growing major economy, has underinvested in infrastructure for years. To turn this around, Duterte has made infrastructure development a top policy commitment since taking office in June 2016.

On April 18, 2017, the Philippine government announced the official launch of a large-scale infrastructure investment program called "Build, Build, Build", known as "the boldest and most ambitious infrastructure construction plan in the Philippines History". In addition, the construction of personal housing in the Philippines is also in full swing.

According to Duterte's idea, infrastructure can not only improve the productivity of economy and create jobs, but also increase income and ultimately reduce poverty. And the government aims to spend between 8 trillion and 9 trillion Philippine pesos (about $180 billion) on public infrastructure between 2017 and 2022.

With the implementation of the infrastructure construction policy, the price of sand and gravel aggregate has been rising continuously in recent two years. According to the statistics, the prices of various common sand in 2019 has doubled than prices in 2018, so the investment of sand aggregate is promising:

If the current gravel market price in the Philippines is 1,000 Philippine pesos per ton (1 cubic gravel in the Philippines is 1,500 Philippines peso), and taking a river stone crushing production line with a capacity of 100 tons of sand and gravel as an example, we can make the following price analysis:

According to the above table, a river stone sand production line with a capacity of 100 tons per hour is profitable greatly, so are the other gravel production lines with different capacities. Therefore, the investment prospects of the sand and gravel production line are broad, and investors can rest assured that they can invest.

Strong support from the government: In addition, due to the implementation of the "Build, Build, Build" program in the Philippines, the government fully supports the sand making industry. Therefore, under the impetus of enterprises and the government's policy on sand and gravel aggregate industry, the Philippine sand and gravel industry is gradually becoming intensive, large-scale, high-efficiency and comprehensive utilization of resources, which not only meets the demand for sand and gravel aggregates in the Philippines, but realizes the orderly mining of sand and gravel aggregates, achieving the double win situation of the aggregate of sand and gravel industry!

The stones such as River stones are silicate minerals with characteristics of hard texture, wear resistance and chemical stability. Therefore, natural sand-making resources, mainly river pebbles, can bring a broad market and rich profits, and also make the investment prospect of artificial sand in the Philippines broader and broader.

The artificial sand can effectively and stably control the technical indexes of sand particles according to national standards and engineering quality requirements, and meet the engineering technical requirements.

The particle size and fineness modulus of the artificial sand can be adjusted according to the needs of the project and combined with the good point of the raw materials and the requirements of the concrete.

The artificial sand production can be combined with the crushing stone production process, which is beneficial to the comprehensive utilization of the mineral source and reduce pollution, thus greatly reducing the production cost of the artificial sand.

Due to the rich resources of the Philippines, its geographical advantages and the characteristics of the raw materials themselves, the crushing and sand-making processes can be easily configured to meet the requirements of the fieldwork.

The sandstone production line has advantages of a high degree of automation, high production efficiency, low operating cost, large output, high yield, high breaking rate, and energy-saving; the finished stone has uniform particle size and good granular shape, which could meet the national high-speed material standard.

The finished product has even particle size and high compressive strength, which is more suitable for construction than the natural sand grains and sand produced by ordinary hammer type sand making machine and can greatly improve the construction quality.

Based on the principle of comprehensive utilization of resources and adapting to local conditions, we use river stones as raw material for processing artificial sand to introduce the process and technology of river stone sand and gravel making line.

According to the characteristics of the river pebble, the process is designed to be three-stage crushing, that is, primary crushing, medium crushing, and sand making. The first crushing is for road building production; the second crushing process and sand making process are combined with the matching screening to form a closed-loop production process to meet the needs of concrete aggregates of various grade ratios.

Equipment used for crushing and sand-making includes vibrating feeder, jaw crusher, impact crusher(for soft ores like limestone) or cone crusher(for hard ores like river stones), sand making machine, vibrating screen, sand washing machine.

The river stones are uniformly sent to the PE600750 jaw crusher by the vibrating feeder for coarse crushing into 65-160mm size. And then the coarsely crushed material is sent to the PSG900 cone crusher by the belt conveyor for secondary crushing into 13-38mm, then is fed into the sand maker for further crushing.

The finely crushed material is sent to the vibrating screen. The material that meets the particle size requirements is sent to the sand washing machine for cleaning and then transported by conveyor belt; the material that does not meet the requirements of the finished grain size is returned into the sand maker to form a closed loop for multiple crushing.

The finished sand is transported to the finished product warehouse via a belt, and the stone powder can be transported into the powder store through the hoister. The finished sand is discharged from the bottom of the sand storage tank through the arc valve into the belt and transported to the sand distribution warehouse. After the water spray treatment, the finished product is delivered, and the stone powder can be delivered through the cement bulk equipment.

At present, the infrastructure construction in the Philippines is in the ascendant, and the demand for sand aggregate is still high and increasing, which brings huge business opportunities for investors.

Meanwhile, the Philippine government is pushing ahead with its infrastructure plans, with the President signing a record 4.1 trillion pesos this year on 6 January 2020 to upgrade aging airports, seaports, roads and railways for a "golden age" of infrastructure.

As a result, the Philippines is expected to remain a hot spot for infrastructure investment in the coming years. For the development of a relatively weak infrastructure industry, investors who focuses on this area must get a good harvest.
