Hongcheng vertical mill is professional milling equipment for coal processing

    People usually call the enterprise which develops coal resources as colliery, mined coal products called as coal. It is not only an indispensable raw material in industry, agriculture and people's daily lives, but also end product which after processed by coal milling equipment is an important raw material in metallurgy, chemical industry, medicine and other departments. With the rapid development of science and technology, the value of comprehensive utilization of coal will become increasingly prominent.

    Coal is very widespread used, and can be divided into thermal and coking coal according to its intended use.

    Thermal coal are mainly used for: 1) Power generation: about 1/3 or more of coal used to generate electricity in China, the average coal consumption of power generation is about 370g / (kW/h) or so of standard coal. By using the calorific value of coal, the heat energy is changed into electric energy in Power plant. 2) Steam locomotive: coal consumption accounted for about 2%; an average coal consumption index of steam locomotive boiler is around 100kg / (10,000tons/km). 3) Building materials: thermal coal consumption accounts for more than l0% and the amount of coal for cement is the largest, followed by glass, brick, tile and the like. 4) General Industrial boiler: Except for thermal power plant and large heating boilers, business and heating used industrial boilers model have a wide range, a large number and scattered, coal consumption accounts for about 30% of thermal coal. 5) Life coal: coal consumption is also a large number for daily life, about 20% of the fuel coal. 6) Metallurgical: metallurgical coal is mainly anthracite for sintering and blast furnace injection, an amount less than 1% of the amount of thermal coal.

    Coking coal mainly used for coke refining. Coke is smelted by coking coal or mixed coal under high temperature, generally about 1.3 tons of coking coal can be smelted into one ton of coke. Coke mostly used for steel making, is the main raw material of iron and steel industry, has been hailed as the "basic food" of the steel industry

    Vertical mill has a very important role in coal grinding and processing, we can use high-tech science and technology to grind coal into finished products of different particle size and fineness. Tell from the feedback of the market, Hongcheng vertical mill has the absolute advantage and application value in the process of coal, with high grinding efficiency, low power consumption, large feeding size, easy adjustment of the product fineness and other characteristics, has become the priority choice for coal grinding.

    HLM vertical mill is advanced mill equipment finally developed by Hongcheng’s technical staff after decades of painstaking research and by learning through the introduction of foreign advanced technology.

    The pressure devices is designed and manufactured through standardized modular, with the capacity of vertical mill increases, the corresponding increase in the number of grinding rollers. It could be 2 rollers or 3 or even4, maximum to be 6 rollers for permutations and combinations. With minimum standard modular components, form a variety capability of products to meet different requirements for product fineness and capacity.

    With trend of powder making industry become large-scale, energy saving, environmental protection, Guilin Hong Cheng is constantly exploring technological innovation, based on the concept of creating value for the customer's, with years of professional experiences in the field of powder solutions, developed this highly efficient and energy-saving HLM series vertical mill. This new milling equipment broken the traditional Raymond mill’s rule for incapable of grind high hardness, high moisture, high fineness product, having a significance meaning for the realization of large scale production of all kinds of materials, can be widely used in electric power, metallurgy, cement, chemicals, non-metallic mineral industries, has a very high degree of credibility and assessment on the coal market.
