Activated Carbon Vertical Roller Mill Production Line For Production Of Activated Carbon From Pulverized Coal

The raw materials for the preparation of activated carbon are very wide, mainly divided into wood and coal. Coal raw materials mainly include anthracite, coke coal, lignite, petroleum, asphalt and petroleum coke. From the perspective of China's activated carbon industrial structure, the output of coal based activated carbon accounts for more than 70% of the total output of activated carbon. The activated carbon vertical roller mill production line is the main raw material production equipment for preparing activated carbon from pulverized coal. As the manufacturer of activated carbon grinding mill, HCMilling(Guilin Hongcheng) will introduce the process of preparing activated carbon from pulverized coal in the HLM activated carbon vertical roller mill production line.

Preparation process of activated carbon from pulverized coal: qualified raw coal is crushed to a certain fineness (- 74μM accounts for 90%), and then add an appropriate amount of binder (generally coal tar) to mix evenly in the mixing equipment, and then extrude the carbon strip with a certain diameter mold under a constant pressure. After carbonization and activation, the carbon strip is screened and packaged into finished activated carbon. It can be seen from the process flow of preparing activated carbon from pulverized coal that raw coal (mainly anthracite) needs to be grinded to a certain fineness first, which is a key step in the process flow of preparing activated carbon from pulverized coal. Therefore, the first problem to be solved in the coal powder preparation of activated carbon industry is to choose which equipment is more effective for anthracite grinding.

As the main raw material for preparing activated carbon from pulverized coal, anthracite is harder and less grindable than bituminous coal in terms of grinding performance. Therefore, under the same fineness requirements, the grinding time of anthracite is longer than bituminous coal, indicating that anthracite is a relatively fragile and difficult to grind material. In the process of preparing activated carbon from pulverized coal in China, the suspension roller mill, also known as the activated carbon Raymond mill, is generally used in the pulverizing system of raw coal. Due to the limitation of equipment structure, the unit hour output is generally only a few tons, and the suspension roller mill needs to be started and stopped frequently, which can not be continuously produced, with low efficiency and high energy consumption; The wear-resistant material is made of high manganese steel, with short service life; High equipment maintenance rate and high labor intensity of workers; As the lower part of the mill is under positive pressure operation, ash leakage often occurs, resulting in poor production site environment, which is not conducive to environmental protection and modern large-scale production. Therefore, improving the production environment, reducing labor costs, significantly increasing the milling capacity, reducing energy consumption, reducing dust emissions, and improving the production efficiency are the main development directions for the preparation of activated carbon from pulverized coal.

HLM series activated carbon vertical roller mill is an efficient and energy-saving grinding equipment designed and developed by HCMilling(Guilin Hongcheng) on the basis of absorbing the advanced technology of vertical roller mill at home and abroad, combining years of experience in the mill industry, and constantly improving and upgrading the production technology of the mill. It has both drying and grinding systems. According to the grinding principle of the material bed, it grinds materials through a relatively moving grinding roller and disc grinding device. It is an efficient and energy-saving grinding equipment that integrates multiple functions of crushing, grinding, drying, sorting and conveying. It has obvious advantages such as large grinding output, good equipment performance and reliable operation.

The HLM vertical activated carbon roller mill has been very mature in the application of coal powder preparation for the boiler, raw meal, clinker and cement grinding for the new dry process cement clinker production line, and coal powder preparation. At the same time, the HLM activated carbon vertical grinding mill production line also has a very mature field application case in the process of coal powder preparation of activated carbon. From the point of view of production site and operation effect, the production capacity of its single unit equipment is greatly improved compared with the traditional grinding mill, which can meet the large-scale industrial production operation of raw coal pulverizing. The production line of the activated carbon vertical roller mill is a typical equipment different from the traditional activated carbon grinding mill, which will play a greater role in the preparation of activated carbon from pulverized coal industry. If you have any needs, please contact mkt@hcmilling.com or call at +86-773-3568321, HCM will tailor for you the most suitable grinding mill program based on your needs, more details please check www.hcmilling.com.
