How to choose coal pulverizer for coal-based activated carbon

The raw materials for preparing activated carbon are very wide, mainly divided into wood-based and coal-based. Coal-based raw materials mainly include anthracite, coking coal, lignite, petroleum, asphalt and petroleum coke. So, how to choose a coal pulverizer for coal-based activated carbon? Can ordinary coal mill be used for activated carbon preparation? Today, Guilin Hongcheng, a coal pulverizer manufacturer for coal-based activated carbon, will analyze and answer your questions.

Activated carbon is prepared from carbon-containing raw materials such as wood, coal and petroleum coke through pyrolysis and activation processing. It has a developed pore structure, a large specific surface area and rich surface chemical groups, and has strong specific adsorption capacity. In the process of processing activated carbon, it is necessary to use a corresponding grinding device to process and grind the activated carbon. Coal-based activated carbon production process: After the qualified raw coal enters the factory, it is crushed to a certain fineness (-74 μm accounts for 90%), and then an appropriate amount of binder (usually coal tar) is added and mixed evenly in the mixing equipment, and then Carbon strips are extruded into carbon strips using a die of a certain diameter under a certain pressure. After carbonization and activation, the carbon strips are screened and packaged into finished activated carbon. It can be seen from the activated carbon production and processing process that the raw coal (mainly anthracite) needs to be ground and processed to a certain fineness. This is a key step in the entire activated carbon production process. Therefore, choosing which coal-based activated carbon coal pulverizer to grind anthracite is more effective is the first problem that the activated carbon processing industry must solve.

As a coal pulverizer manufacturer for coal-based activated carbon, Guilin Hongcheng's Raymond mill and vertical roller mill have been successfully used and recognized in coal-based activated carbon production projects. Among them, Raymond mill, as a coal pulverizer for coal-based activated carbon, has the advantages of low price and small footprint, and is suitable for the processing and production of small and medium-sized enterprises. However, due to equipment structure limitations, the output per unit is generally only a few tons, and continuous production is not possible. The efficiency is low and is not suitable for large-scale production. In order to greatly increase the grinding capacity and reduce energy consumption, the HLM vertical roller mill launched by Guilin Hongcheng has become a more ideal choice for coal-based activated carbon coal pulverizer.

The HLM type vertical roller mill has been very mature in applications such as the preparation of pulverized coal for boilers and the grinding of raw meal, clinker and cement in new dry cement clinker production lines, as well as the preparation of pulverized coal. It is also used in slag, gangue and There are also mature field application cases for grinding high-hardness and difficult-to-grind materials such as slag. It has both drying and grinding systems. Based on the material bed crushing principle, materials are ground through relatively moving grinding rollers and grinding disc grinding devices. It integrates multiple functions of crushing, grinding, drying, sorting and conveying. The integrated high-efficiency, energy-saving grinding equipment has obvious advantages such as large grinding output, good equipment performance, and reliable operation.

Judging from the production site and operation results of the HLM vertical roller mill processing coal-based activated carbon raw coal, its single-machine equipment production capacity is greatly improved compared to the traditional Raymond mill, and it can meet the large-scale industrial production operations of raw coal grinding. This vertical roller mill is a typical equipment that is different from traditional grinding mills and will surely play a greater role in the processing of coal-based activated carbon raw material coal.
