To calculate the tons per hour (TPH) capacity of a ball mill machine, you need to determine the volume of the ball mill, the density of the material being milled, and the operating hours. Here is a simplified approach to get an estimated capacity: Ball Mill Volume (V): Measure the internal diameter (D) and length (L) of the drum in meters.

201611· The first stage of size reduction of hard and large lumps of run-of-mine (ROM) ore is to crush and reduce their size. Softer ores, such as placer deposits of tin, gold, mineral sands, etc., do not require such a treatment. Large-scale crushing operations are generally performed by mechanically operated equipment such as jaw crushers, gyratory crusher and roll crushers.
