Our ATOX174 Coal Mill is a compact vertical roller mill that can grind almost any type of raw coal The coal mill utilises compression and shear force generated between the large rollers and the rotating table to crush and grind raw coal removing the need for a separate piece of equipment for crushing.
Vertical Coal Mill also known as coal mill for superfine grinding of raw coal soft coal specifically for cement power plant steel mill and other fields.
Coal vertical mills are designed to achieve the maximum rated capacity grinding a design coal with a grindability of 55 HGI and 812 percent moisture and achieving a discharge fineness of 70 per cent passing a 200 mesh screen 74 micron and 995 per cent passing a 50 mesh screen Variation of the coal hardness andor moisture content will effect up or down the discharge capacity or the discharge.
Now although I chose coal as the working example for this 3D model this type of grinding mill is often used also in the cement industry for crushing various rocks but thermal power stations coal fired power stations will often have one of these vertical grinding mills if theyre quite large in size or if they have a large megawatt capacity.
Vertical roller mill can replace ball mills or tube mills used for preparing coal Today VRMs with capacities up to 50 tph are the dominant technology for coal grinding Grinding media wear in a VRM will only be 5 to 10 gton of coal powder as compared to 100 gton of coal powder in a ball mill.

3 Grinding and drying test with vertical roller mill For the study of the grindability and drying characteristics of highmoisture coal with the vertical roller mills grinding and drying tests were carried out using a reducedscale model of a vertical roller mill to verify the continuous and stable operation and drying characteristics.
Vertical Cement Grinding Mill produced by China ZK Corp is is a new type of high efficiency energy conservation and environmental protection of grinding equipment widely used in the grinding of raw cement slag cement clinker raw coal and other raw materialsIt gathers grinding drying and powder selecting as a whole with high grinding efficiency and high drying capacity the maximum.
1Raw coal diameter equal to or less than 38 mm is fed to the rotating grinding bowl via a coal feed pipe connected to the center of the coal feeder The amount of coal fed is automatically determined according to the amount of power generated by the generator set coal quality and the number of mediumspeed coal mills put into operation.
Vertical Roller Mill For Grinding Coal Czeu Vertical roller mill is a kind of energyefficient grinding machines which is widely used in many fields such as producing raw and clinker material grinding slag ore industrial silicon calcium carbide residue coal gangue in the cement industry and desulphurization process in the industries of coal.
KHD has ordered a grinding plant with an MPS 225 BK mill from Gebr Pfeiffer to produce pulverized coal The mill with a drive power of 370 kW will grind 35 th of coal to a product fineness of 15 R 90 181m At the same time the coal which may have a feed moisture of up to 10 is dried in the mill.
The vertical roller mill coal grinding system is generally composed of a vertical roller mill main body a fine powder collecting device a fan and a pipeline The working process is that the raw coal enters the vertical roller mill and is ground by the air or hot air into the classifier and the fine coal is collected by the fine powder.
