When LM series vertical mill plant works, main motor will drive the grinding disc with the reducer, meanwhile hot air coming into the mill via air inlet.Material fall into the center of cavity from feeding hopper and move towards the edge of grinding disc under the centrifugal force.

Pulverizer - Wikipedia

With adequate mill grinding capacity, a vertical mill equipped with a static classifier is capable of producing a coal fineness up to 99.5% or higher <50 mesh and 80% or higher <200 mesh, while one equipped with a dynamic classifier produces coal fineness levels of 100% <100 mesh and 95% <200 mesh, or better.

Coal vertical mill - CHAENG

The vertical mill adopts air sweeping type operation. By adjusting the incoming air temperature and air volume, it can grind and dry the raw coal with moisture up to 10%, and solve the requirement of high moisture drying with a large amount of wind. 4.Sealed structure, energy saving and environmental protection

Coal vertical mill_cement production process_Cement epc ...

The raw coal coming in through the coal falling pipe is distributed on the mill disc.Small particles of coal are crushed by the relative motion of roller and disc.When the raw coal is ground in the mill, the hot air (generally below 300℃) fed into the vertical mill will dry the moisture of the raw coal and meet the requirements of finished ...
