Today the air-swept vertical roller mill is the standard solution for coal grinding installations. And thanks to our contin- uous refinement of the ATOX coal mill over the years, today’s leading air-swept vertical roller mill is the compact ATOX. Offering high reliability, low installation costs and a wide range of sizes, the ATOX grinds and dries all types of coal while providing
coal mill Mill (Grinding) Screw The three grinding rollers, mounted in fixed position, are passed down on the table under hydraulic loading. Raw coal enters through the center of the mill and is deposited on the grinding table. Centrifugal force feeds the coal radially outward where it is ground between the roller tyres and grinding track.
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 (mm) when coupled with a variable speed mill motor.

Reduced operations and maintenance cost via extension of time between overhauls Improved mill availability Longer acceptable coal fineness results from longer lasting grinding surface profile Reduced frequency of grinding roll to grinding segment gap adjustments No spauling which can occur with other materials Maintains grinding surface profile longer than any otherhigh chrome and ceramics
Grinding gap and particle size are reduced towards the end from roller mills which the grinding begins. The reason for this is that each process has disintegration and contraction while making gradually cutting, sorting and scraping actions during the separation of endosperm and bran. Therefore the grinding gap will be less in the next crushing process. This range varies depending on the

There are three grinding roller wheel assemblies in the mill grinding section, which are mounted on a loading frame via pivot point. The fixed-axis roller in each roller wheel assembly rotates on a segmentally-lined grinding table that is supported and driven by a planetary gear reducer direct-coupled to a motor. The grinding force for coal pulverization is applied by a loading frame. This
