Coconut shell activated carbon preparation process and coconut shell activated carbon grinding equip

What is activated carbon?

Activated carbon is a porous carbon-containing substance with a highly developed pore structure. 

The porous structure of activated carbon provides it with a large surface area, which can fully contact with gas (impurities), thus endowing activated carbon with unique adsorption properties. 

It is very easy to achieve the purpose of absorbing and collecting impurities. Just like magnetism, all molecules are attracted to each other. Because of this, a large number of molecules on the pore walls of activated carbon can generate a strong attraction, so as to achieve the purpose of attracting harmful impurities into the pores. 

However, not all activated carbons can adsorb harmful gases. 

Only when the pore structure of activated carbon is slightly larger than the diameter of harmful gas molecules and can allow harmful gas molecules to enter completely (not too large or too small) can the best adsorption effect be achieved.


What is coconut shell activated carbon?

Coconut shell activated carbon uses coconut shell as raw material. It is made by carbonization, activation, and grinding process. 

The appearance is amorphous particles, with high mechanical strength, developed pore structure, large specific surface area, fast adsorption speed, good adsorption capacity for various solutes and free gas, etc., suitable for high-purity drinking water, beverages, alcohol, Deodorization, dechlorination and liquid decolorization of food and medicine, and can be widely used in solvent recovery and gas separation in chemical industry.


How to produce coconut shell activated carbon?

Coconut shell activated carbon adopts the production process of non-bonded activated carbon. Change the traditional manufacturing process of forming with traditional binders such as coal tar and starch. It does not contain binder components, and it depends entirely on the affinity between carbon molecules and the special properties of the raw materials themselves. Made with scientific formula, it can effectively avoid clogging of carbon pores and give full play to the adsorption function of rich and developed carbon pores.


It is made from powdered crushed carbon produced in the production process of coconut shell activated carbon as raw material, which is pulverized, mixed, extruded, formed, dried, carbonized and activated. Coconut shell activated carbon is gray-black granular in appearance, odorless and non-toxic, has the advantages of compact structure, low ash content, high strength, cheap and easy to obtain, etc., and is widely used in waste gas and wastewater treatment.

What are the coconut shell activated carbon grinding equipment?

1. Coconut Shell Activated Carbon Raymond Mill

Raymond mill can process materials with Mohs hardness below 7, the moisture content of the material is required to be below 6%, the fineness range of the finished product is 0.8-0.045mm, and the processing capacity is 0.8-9.5 tons per hour.

The material below 20mm is sent to the feeding hopper by the bucket elevator. The feeding hopper sends the material into the grinding chamber and falls on the grinding ring. The continuously rotating grinding ring gives the material a centrifugal force to move it to the outer circle. , into the grinding range of the grinding roller.

After grinding, the material falls from the edge of the grinding ring, is blown up by the hot air sent by the blower, and is separated by the cyclone separator. The qualified material leaves the grinding chamber, and the unqualified material falls back into the grinding ring.

2. High pressure micro powder mill for coconut shell activated carbon

The high-pressure micro powder mill is an advanced version of the Raymond mill, which grinds materials by the extrusion force generated by the opposite rotation of two horizontally installed extrusion rollers. After the material enters the grinding chamber, the closed material layer moves downward under the action of gravity. During the movement, it is pressed into a cake by the pressure of the extrusion roller, and the cake contains a large amount of fine powder.

The feed particle size of the micro powder grinding mill is below 15-25mm, the finished product particle size is 0.125-0.010mm, and the production capacity is 0.2-12 tons per shift.

3. Ultrafine grinding mill for activated carbon

The three-ring/four-ring ultra-fine grinding mill grinds the material repeatedly through multiple loops to obtain ultra-fine powder efficiently.

The main part of the ultrafine grinding mill is composed of the main engine, the reducer, the analyzer, the fan, the bypass powder collector, the maintenance platform and the electric control cabinet. The auxiliary machine part consists of jaw crusher, bucket elevator, electromagnetic vibrating feeder, storage bin and so on.

The material enters the equipment, is thrown to the edge of the turntable, falls into the grinding chamber, and undergoes multiple grinding to become powder. The fan pulls the ground powder away, which is controlled by the powder concentrator. The powder that does not meet the requirements is returned to the machine cavity and ground again to become finer. The powder that can pass through the powder separator is the finished product, and the pulse dust collector separates the powder from the air to achieve the purpose of collection. The production process operates under negative pressure, and there is no dust spillage.

The fineness of the finished product of the ultrafine pulverizer is between 150-3000 mesh, and the output can reach up to 50 tons/hour.

4. Coconut shell activated carbon vertical roller mill

Vertical roller mill is a grinding equipment that integrates crushing, drying, grinding, grading and conveying. The grinding principle is similar to that of Raymond mill. The difference is that it can blow hot air into the grinding chamber, saving a The cost of the dryer.

The fineness of the finished product of the vertical roller mill is between 0.17-0.033mm, the model is from small to large, and the processing capacity can be from 10-40 tons per hour to 90-320 tons per hour.

5. European style coarse powder grinding mill

The European-style coarse powder grinding mill can crush all kinds of ores with a compressive strength of not more than 320MPa. The structure of the coarse grinding mill mainly includes a casing, a rotor, a hammer head, a grate bar, etc. The materials are crushed by the impact force brought by the high-speed rotating hammer head. The humidity of the crushed material should not exceed 5%.

The feeding particle size of the European-style coarse powder mill is below 100mm, and the output particle size is 0-3mm, which can process 35-132 tons of materials per hour.

To sum up, how much the output size of plagioclase powder can reach depends on what kind of mill you use.
