Method of assessing ball mill health
· to calculate a "Levin B value" which is the kW·h per revolution of a Bond laboratory ball mill. Dividing ball mill grindability (g of product/rev) by the Levin B (kWh/rev) gives the desired units of measurement (g/kWh). The Levin B is calculated from a Bond ball mill grindability test as follows: B= ×10−3× P100 (100−U)

Ball mill
A ball mill is a type of grinder used to grind or blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. A ball mill consists of a hollow cylindrical shell rotating about its axis. T

Empirical and scaleup modeling in stirred ball mills
· At constant recipe, a scaleup of stirred ball mills based on the passage number is possible when mills (both production and laboratory stirred ball mills) are of similar geometry and equal grinding media with equal filling ratios are used. The peripheral speed has to be kept constant and the charge size as well as the throughput can be calculated. When one of these .
