The ball mill is a cylindrical drum that rotates around its axis, causing the steel balls to tumble and grind the coal into a fine powder. It is classified as an impact mill, based on the principle of impact and attrition. The size of the ball mill and its capacity depend on the amount of coal feed, mill dynamics, and the desired end product.
