Charcoal briquette is a kind of fuel made by charcoal powder. Compared with traditional fuels, charcoal briquettes can not only generate heat continuously but also produce no smoke and odor during combustion.

Therefore, it has been widely used in domestic and industrial applications in recent years and has become the most popular fuel in many countries such as Kenya, the Middle East, Uganda, India, etc.

With the increase of its economic benefits, the charcoal briquettes process has become one of the hottest processing industries. So, what are the ingredients of charcoal briquettes and how to make charcoal briquettes?

The charcoal briquette is mainly composed of two parts, the charcoal which is used to provide heat and the minor ingredients. Charcoal is the product of incomplete combustion of wood or wood raw materials or pyrolysis under the condition of air isolation.

Charcoal accounts for more than 70% of the entire charcoal briquettes. As the combustion material providing heat, the raw materials for charcoal can be various woods, such as beech, birch, hard maple, pecan and oak.

The charcoal is mainly processed by the kiln. In general, the charcoal produced and extinguished in the kiln is called black wood charcoal. It has the advantage of being easy to ignite, but it is easy to explode during burning with a short burning time and much smoke.

While the white wood charcoal can be oxidized and generate white ash after being carbonized, removed from the kiln and quenched with wet sand. Compared with black wood charcoal, it has a harder texture.

The charcoal briquette cannot fully contact with oxygen during the combustion process, so the accelerator is needed to accelerate the combustion. The most suitable accelerator is the nitrate, which can not only provide oxygen to accelerate combustion but also heat during combustion.

By observing the degree of turning white, we can judge the burning degree of the charcoal briquette. In addition, because the white ash is not combustible, it can effectively extend the burning time.

Numerous facts show that starch has the best performance as a binding material. After it's gelatinized, a thick paste can be formed so that the charcoal powder is stuck together to facilitate the later briquette.

After the end of combustion, close the air inlet, and after one to two hours of exhaust, close the exhaust hole. After a two-week cooling period, empty the kiln and crush the carbonized wood (charcoal).

Use a hammer crusher or roller crusher to crush the carbonized wood. Although different types of wood such as bark, dry wood chips, wet wood and so on should be crushed to different sizes, generally they can be crushed into pieces of charcoal to 5mm below to make high-quality charcoal briquettes.

Then a drying process is needed. If the water content exceeds the empirical upper limit, the temperature will rise and the volume will expand suddenly, which is easy to cause an explosion. If the moisture content is too low, it will be difficult to mold. Use a dryer to reduce its moisture content to the level required for briquettes formation by about half (to about 15%).

Briquetting is a key step in charcoal molding. After the raw materials enter the ball press, they will be subjected to three kinds of forces, namely the main driving force of the briquette machine, the friction force and the centripetal force of the wall.

Due to moisture, adhesives, temperature (about 105 F or 40 C) and pressure of the rollers of the briquetting machine, the charcoal briquettes can maintain their shape when they fall from the bottom of the machine.

After production, bag the charcoal briquettes immediately or stored them in silos. Following the above steps, charcoal briquettes will be produced at a production rate of 2200-20,000 pounds (1-9 metric tons) per hour.

According to the content above, it is not so difficult to process charcoal briquettes. But we need to pay attention to many details, such as component ratio, moisture, all of which will directly affect the final quality.

Therefore, the author recommends that the users need to understand and confirm every step and its details of the charcoal briquettes processing ahead. And then choose the reliable supplier for the purchase of the equipment needed in the processing, such as crusher, dryer, briquette machine, etc.

Nowadays, all industries are implementing the environmental protection concept "everyone has a responsibility to protect the environment". Many kinds of waste have been recycled and turned into treasures.

For example, construction waste can be recycled and crushed into building aggregates; powder produced by the mining process can be reused after processing; the desulfurization gypsum of the power plant can also be used to replace natural gypsum.

All these types of powder, waste, residue materials such as coal powder, iron powder, coking coal, aluminum powder, iron filings, iron oxide scale, carbon powder, carbon powder, slag, gypsum, tailings, sludge, kaolin, activated carbon, coke can be pressed.

First of all, the finished charcoal briquettes not only have the characteristics of smokeless, odorless, non-toxic, environment-friendly, but also has large heat, long burning time and are stable in heating.

Secondly, because the a briquetting machine or plant can produce material into different shapes, the final product is convenient for storage and handling. Besides, the finished product has a superiority that it is cheaper than other fuel.

Coal ash, commonly known as fly ash, refers to the dust and tailings collected from the coal-fired (including coal gangue and coal slime) smoke and the desulfurization and denitration ash generated in the production process of the thermal power plant.

The coal ash particles have a porous honeycomb structure, a large surface area, and a high adsorption activity, and the particle size ranges from 0.5 to 300 microns. And the bead wall has a porous structure, the porosity is as high as 50%-80%, and has strong water absorption.

With the development of the power industry, the amount of coal ash discharged from the thermal power plant has increased year by year, making it one of the most industrial wastes with current displacement.

If there are too much coal ash, it will pollute the atmosphere; if it is discharged into the water system, it will cause the siltation of the river, and the toxic chemicals in it will harm the human body and organisms. For these reasons, human beings need to press it into briquettes.

On the other hand, it is used as a raw material to obtain various benefits through processing. It can make coal powder burn more completely, get more heat energy and save resources, besides, it is clean and easy to store.

The rate of raw material consumption and waste generation in the metallurgical process is staggering. As the plant operates, lime powder is continuously produced and piled up. Before too long, it will cause blockages and environmental pollution.

However, if recycled, it is still a resource. Since it is powdery, it is difficult to store and transport. So, it is the most correct way to process it into chunks. Therefore, the quicklime dry powder briquette machines came into being.

Desulfuration gypsum, also known as flue gas desulfurization gypsum, sulfur gypsum or FGD gypsum, is industrial by-product gypsum obtained by desulfurization and purification of flue gas generated after combustion of sulfur-containing fuel (coal, oil, etc.).

According to the difference between the burning coal type and the dust removal effect of the flue gas, the desulfurized gypsum presents different colors from the appearance. Generally, the common ones are grayish-yellow or grayish-white, and the desulfurized gypsum of good quality is pure white color.

It mainly comes from the flue gas desulfurization process of the thermal power plant. Most of the power plants adopt the limestone-gypsum desulfurization process. At present, nearly 20 countries have adopted the flue gas desulfurization process in the world.

The sulfur dioxide in the flue gas is oxidized with calcium carbonate and air in the slurry to form calcium sulfate, and the calcium sulfate reaches a certain saturation, the calcium sulfate dihydrate will be crystallized, and then is discharged into the absorption tower, concentrated, dehydrated, and transported to a gypsum silo for stacking.

The price of desulfurization gypsum briquette is low. Compared to natural gypsum, desulfurized gypsum is renewable, the purity is higher, and the composition is more stable. It is easy to use after briquetting. People can make full use of the materials while reducing air pollution and dust pollution.

The above is a brief introduction to the 5 most common materials in the briquette machine. If you have any questions about the article, please let us know by leaving a message or chatting online, we will reply in 24 hours.

Applied materials: graphite powder, fly ash, scale cinder, vanadium titanium ores, iron ore fine, carbon dust, quicklime powder, magnesia powder, copper concentrate, chromium ore powder, lead and zinc waste, bauxite, etc.

Hydraulic briquetting machine is a new generation of products developed by the mature and advanced technology and based on the development direction of domestic and foreign briquetting enterprises.

The hydraulic ball press machine adopts a hydraulic system which can increase the pressure intensity. Its hydraulic axis tightens and the whole machine has a compact structure with sturdy and durable Performance.

Hydraulic system: Its main function is to automatically provide a stable pressure to the pressure roller, and it also has the function of energy storage and safe overflow. The hydraulic system consists of a fuel tank, an oil pump, an oil filter, a relief valve, a check valve, and an accumulator.

The hydraulic ball press has a wide range of practical applications, and can process a variety of materials and powders, such as cryolite, alumina, fertilizer, metal magnesium powder, bauxite, aluminum ash, etc., and non-ferrous metals industry powder, auxiliary materials, powders in the refractory industry.

The hydraulic ball press machine can process a wide range of powder materials that are difficult to form balls like graphite powder, charcoal, fly ash, oxide skin, vanadium-titanium ore powder, steel making refining agent, iron fine powder, quicklime powder, magnesia powder, copper concentrate, chromium ore powder, lead and zinc wastes, bauxite, refractory matter as well as nonferrous powder.

The hydraulic briquette machine runs relying on the cooperation of driving and driven shaft supported by the exposed gear which is driven by the electromagnetic speed regulating motor; after being driven by the belt wheel and cylindrical gear reducer, the power is transferred to the pin coupling shaft.

Hydraulic pressure device is installed on the back of the driven shaft block, driven by the electromagnetic speed regulating motor, and after the belt wheel and worm reducer running, the spiral feed device presses materials into the main feed port.

As the constant matrix of the electromagnetic speed regulating motor, when the spiral feeder has the same pressing quantity with the inventory of the main body of the press machine, the feeding pressure will stay constant, thus stabilizing the balling quality.

The hydraulic protection device is driven by a hydraulic pump to generate high-pressure oil into the hydraulic cylinder and make the piston do axial displacement. The front joint of the piston rod is placed on the bearing housing to meet production pressure requirements.

When there are too much feeding materials between the two pressure rollers or entering the metal block, the hydraulic cylinder piston rod will be in a situation of pressure overload, which will cause the hydraulic pump to stop, the accumulator to buffer the pressure change, the relief valve to open the oil return, and the piston rod to be displaced.

And the gap between the pressure rollers is increased to allow the hard object to pass through, and then the system pressure returns to normal, thereby protecting the pressure roller from damage. The briquette machine can adjust the pressure according to the requirements of the pressure ball density with flexible production.

For materials that are difficult to form and the materials whose natural characteristics cannot be added with binders are all required to be pressed by a hydraulic briquetting machine. Under these circumstances, it creates a broad market prospect for the hydraulic ball press machine.

Compared with the ordinary ball press machine, the hydraulic ball press machine has superior performance and reasonable price, and has gradually become the mainstream product on the market and chosen by more and more customers.

Fote Heavy Machinery is a joint-stock enterprise mainly targeting in production of the heavy machinery, and integrating R&D, production and sales. The company's ball press equipment is made of high wear-resistant materials, with high molding pressure and meets production standards.

The resources of mineral powder, coal powder, coal slime and other materials in India are abundant. In order to improve the comprehensive utilization rate of these materials, most users will choose the briquette machines to improve the use-value of them.

10 common problems in the operation of briquette machine | fote machinery

10 common problems in the operation of briquette machine | fote machinery

Briquette machineis also known as a briquetting machine, which is used to press the material that hard to be shaped, and it has the advantages of high molding pressure, adjustable rotational frequency and is equipped with a screw conveyor.

It can be divided into several types of briquette machines according to the materials, such as charcoal briquette machine, coal briquette machine, powder briquette machine, gypsum briquette machine, etc.

It also can be divided into several types of briquette machine according to their functions, such as common briquette machine, hydraulic briquette machine, strong hydraulic briquette machine, etc.

Under this condition, one of the reasons is the temperature or the water content in the raw material is out of normal range, and the corresponding solution is drying materials by the dryer to ensure that the materials are kept at proper temperature and humidity.

Another reason is that there are damages with the parts of the briquette machine, such as the screw conveyor is worn seriously. When it happens, the parts of the briquette machine should be replaced immediately.

Repeat restart of the briquette machine is usually caused by the low power supply, which can not drive the briquette machine to work normally. To solve this problem, it would better suit the remedy to the case.

First, the power supply voltage of the briquette machine is detected by AVO meter, and it'd better detect under the condition that the briquette machine is loaded so that to judge whether there is any power supply problem.

What is particularly noteworthy is that the consumed power of the outer briquette machine is quite different when the heater is on or off. It must be paid attention to the maximum power of the briquette machine to ensure that the briquetting machine can work normally with enough power supply.

In addition, when the briquette machine works normally, the power voltage would better be no less than the standard voltage. When the standard voltage is at the value of 24VAC, the voltage fluctuation should be no more than 25%.

When the line is laid out, the strong current and weak current should be arranged separately to avoid the interference between them. Since the inner space of the briquette machine is limited, the internal power supply makes the strong and weak current coexist, which may impact the weak current signal.

There is insufficient oil pressure during the running process of the briquette machine. The reason causing such a problem may be the blockage of oil suction or the deformation of the joint gasket.

If the oil suction is blocked, it should be cleaned and washed immediately to ensure the cleanness of briquette machine equipment; if the joint gasket is deformed, it should be replaced the deformed gasket with a new one, so that the briquette machine can work normally and efficiently.

During the installation of the briquette machine, the suspension installation method is adopted by several users, but there is still a gap between the briquette machine and the bracket hinge. It is raining or snowing, the water may permeate into the briquette machine to cause damage.

Also, the bracket is quite important, and it is recommended to adopt the original bracket. The original bracket is fully considered the water-proofing problem, such as the inclination is designed to lift the screw end of the briquette machine, preventing the back-flow of water.

Mineral powder briquette machine, coal powder briquette machine and others may cause the deformation problem of materials, and the reasons are usually the insufficiency of materials fed, the insufficient hydraulic pressure, the damaged roll surface, etc.

First, the driven gear should be found, because there is set anadjusting panel. Second, loose all the screws on the adjusting plate, so that to make the panel adjustable. Third, measure the dislocation gap between two sockets, adjust the gap to set the sockets in a proper position.

Whenthere is a dislocation between sockets, except the adjustment of sockets by scientific methods, there still should be paid attention to the shaft. Therefore, the shaft should be checked whether there is any damage.

Sometimes, the finished productsare deformed after shaped by the whole process, for the reason is that the raw materials contain much water. To solve this problem, it can reduce the water content in the materials. The methods are natural-dry or drying by a dryer.

The corresponding solutions are: first, turn off the briquette machine to remove the impurities; second, adjust the voltage or reduce the feeding speed; third, heat the materials to reduce the water content and control it in the range of 6% to 12%.

If there produces much dust during the briquetting process, the cyclone dust collector can be equipped as the corollary equipment. The dust collector has the advantage of cleaning the dust in the machine immediately and improving the working efficiency greatly.

The cyclone dust collector is simple in structure, durable in service. Under normal conditions, the cyclone dust collector can collect the dust of more than 5 m, and the separating ratio is more than 90%.

Therefore, the author suggests that users should havea certain acknowledge of the working principle, using techniques and operating methods when a purchasing briquetting machine, so that the service life, working efficiency and profit can be improved under the same investment.

how does a briquette machine work - types and making process

how does a briquette machine work - types and making process

There are several types of briquette machines with different working principles, they work on different pressures and suitable for different materials. So how they workdifferently? What are there advantage and disadvantages? Lets follow the article.

A briquette machine is used to turn the waste powder to a regular shape block, which can help to improve the conditions for those powder, make them easy for transportation, storage, and more useful for further usage.

Briquetting work always work with the binder as it needs the binding effect to get enough strength for the finished briquette. Biomass and industrialwaste are different from each other due to their binder sources.

The heating system is a special design for those briquettersdeal with materials contain lignin, lignin alway can be found on biomass. So theheating system is usually used for biomass briquetting. Other materials like coal, charcoal, etc. Binders are always needed when briquetting with the screw type briquette machine.

The suitablematerial is fed to the hopper and then conveyed by the screw inside the briquette machine.the rotating screw takes the material from the feed port, and compacts it against a die which assists the build-up of a pressure gradient along the screw.

As the screw briquette machine works with a pressure not that high, binders are always needed forming the briquette. Equip with a heating system will help the biomass material melt the internal lignin and turn it to a high-performance binder. Besides, other materials also work with this briquetterlike coal, charcoal, etc. These materials should be well mixed with the binder to get the briquette forms.

The briquette working process is in a chamber where materials are fed into, there materials are briquetting under a very high pressure. It causes theirplasticity and makes them binding stably together as a block.

Hydraulic type takes a long pressure keeping time on the briquette, this prevents theshort-time material deformation rebound and will cause a special heating for those materials like sawdust for melting its internal lignin, make the briquette with higher strength.

The piston type uses the rotary power of the mechanical device or the thrust of the hydraulic cylinder to reciprocate the piston (or the plunger), and the piston (or plunger) drives the ram to reciprocate in the forming sleeve to generate a pressing force to form the material to briquette.

A big pressure will be generated as the movement of the flywheel and punch the briquette time after time in a short time, it raises the temperature of the raw material. As the raw material moves, it fractionates with the inside, another kind of heat friction heat generates. With the action of these two kinds of heat, material raises its own temperature to a high level and melt the lignin. Particle materials then bind together and become strong enough.

Roller press works with two close rotating rollers at the same speed butwith opposite direction. The two rollers, with the same width and diameter, have holes on the surface. When they move, the same two holes on the different roller will coincide at the intersection of the midline and the briquette will be pressed there.

A normal roller press will use a wedge iron to fix the movable roller as it works on a low pressure. The hydraulic pump station is also can be used to fix the roller and supplies a much bigger but flexible support to the roller to work stable on big pressure.
