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 ...

The large surface area of the pulverized coal and the high temperature inside the mill lead to rapid oxidation of the coal. This results in further heat buildup and the potential for a fire. If the mill is restarted without first removing the hot coal, an explosion can occur when particles are suspended and exposed to the air.

When a blanket clings to horizontal or vertical fuels, two actions occur: the water in the blanket evaporates or drains out and the bubbles break. This both cools the fuel and allows moisture penetration. These actions first slow, and then stop pyrolysis, provided enough is applied. Class A is not a chemical fire retardant.
