Activated carbon is a carbon material with high specific surface area, high porosity and high adsorption performance. It is usually obtained by high- temperature carbonization and activation of carbon raw materials. According to different raw materials, activated carbon can be divided into wood activated carbon, coal-based activated carbon and synthetic activated carbon.
Select suitable coal as raw material, crush, grind, dry and screen pretreatment, and then carbonize at high temperature under anoxic conditions; then react the carbonized material with gas activator at high temperature to expand the pore structure and specific surface area; finally, remove impurities through washing, drying and other post-processing processes to make finished coal-based activated carbon.
Using coconut shell, fruit shell (core) or washed coal as raw materials, after crushing and grinding, a porous structure is formed through steam activation or secondary activation (high temperature oxidation); then multi-stage impurity removal (including sand removal, sorting, pickling, washing) and screening treatment are carried out to remove impurities and unqualified particles; after drying, secondary crushing and fine screening, the finished products are packaged according to particle size to ensure that the products meet different application requirements.
After years of research and testing, Liming Heavy Industry has developed the LM vertical roller mill specifically for the preparation of coal-based new materials. It is suitable for anthracite, bituminous coal, lignite, etc. The finished product fineness can be adjusted, the equipment runs stably, the energy consumption is low, the output is large, and the degree of intelligence is high. The coal-based new material preparation system is equipped with "five-level safety and explosion-proof measures", realizing a fire and explosion-proof system covering the entire area, the entire process, and all source points, effectively ensuring the safe and stable operation of the system, with reliable safety performance, and winning a large number of repurchase orders and wide praise from customers.

In the process of activated carbon preparation, the raw materials need to be processed to a certain fineness to ensure the activity of the subsequent finished product. This is a key step in the entire preparation process. Based on its nearly 40 years of R&D and manufacturing experience, Liming Heavy Industry has launched the MTW European version mill suitable for grinding a variety of materials to meet the grinding conditions of users with different raw material conditions. It is widely used in many enterprises with stable operation, reliable quality, green environmental protection, and economic investment, and has won the recognition of customers.

Its demand has been increasing year by year with the development of society and the improvement of people's living standards. Especially in recent years, with the increasing requirements for environmental protection, the demand for activated carbon at home and abroad has increased year by year.
Activated carbon can be used for the treatment of waste gas and wastewater generated in the steelmaking process. Adding activated carbon to the wastewater treatment pool and treating it together with activated sludge through adsorption can reduce the content of pollutants in the wastewater and improve the treatment effect of the wastewater.
Activated carbon can effectively adsorb various organic matter, heavy metal ions, microorganisms, odors and other harmful substances in water to improve water quality and taste. Especially in emergency situations, coal-based activated carbon can quickly absorb toxic and harmful substances in water to protect people's lives.
Activated carbon can be used to remove impurities, odors and pigments, and protect the original flavor and color of food and beverages. At the same time, activated carbon also has good hygroscopicity and adsorption, which can help store and preserve food and beverages.
Activated carbon can be used as a fertilizer additive to improve the resistance and resistance of crops to diseases and pests. At the same time, activated carbon can also improve soil structure and improve soil water and fertilizer retention.
Activated carbon is also widely used in other fields. It can be used as a catalyst and catalyst carrier in chemical, pharmaceutical and metallurgical fields. At the same time, activated carbon can also be used in textiles, printing and dyeing, leather and other fields to improve product quality and performance.
