vertical roller mill for grinding coal

Vertical roller mills (VRM) 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. According to MIIT grinding media wear in a VRM will only be 5 to 10 g/ton of coal powder as compared to 100 g/ton of coal powder in a ball mill.

Long-lasting coal mill for efficient grinding FLSmidth

Our ATOX® 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. The coal mill can also grind petroleum coke and anthracite down to a fineness below 5% +90 micromillimeters

ATOX coal mill - FLSmidth

ATOX coal mill. Working principles The raw coal enters the mill via a rotary sluice and feed chute and is discharged onto the rotating grinding table. The rotation of the table accelerates the flow of material towards the grinding track, where the coal is ground between the table and the three rollers. The coal then continues over the dam

Coal Mill - an overview ScienceDirect Topics

The fineness of the milling product and the capacity of the pulverizer are strictly connected. With increased fineness grows the overall circulation rate of coal in the mill, coal retention time and the flow resistance. As a result, the maximum mill capacity decreases and the rate of change of operational parameters of the furnace system deteriorates. In extreme cases, the performance of the boiler may
