6. TYPES OF COAL PULVERIZER • Tube or ball mills: Low-speed machines that grind the coal with steel balls in a rotating horizontal cylinder. If the diameter of the cylinder is greater than the length of the cylinder, the mill is called a ball mill. If the length of the cylinder is greater than the diameter of the cylinder, it is called a tube mill.
