The ball millis the key equipment for the material to be crushed and then crushed. This type of grinding machine is to put a certain number of steel balls in its barrel as grinding medium. The ball mill is a horizontal cylindrical rotating device, and the material is fed into the first silo of the ball mill by the feeding device through the f…
However, the unit cost for wear parts for a ball mill is much lower than for a vertical roller mill. For a ball mill grinding OPC to a fineness of 3200 to 3600 cm2/g (Blaine) the cost of wear parts (ball, liners and mill internals) is typically 0.15-0.20 EUR per ton of cement.
A ball mill is a type of grinder used to grind and blend materials for use in mineral dressing processes, paints, pyrotechnics, and ceramics. It works on the principle of impact and friction between rotating balls and the powder materials. The ball mill consists of a rotating drum and a hollow cylinder filled with grinding media, typically ...
