A procedure for rapid determination of the Bond work

01/09/1989· The grindability of an ore in the process of mineral dressing can be determined by use of the Bond work index (W i). This index is determined on a laboratory-scale using a Bond ball-mill and by simulating dry grinding in a closed circuit until the 250% circulating load has been obtained. This happens only after 7–10 grinding cycles, which shows that the procedure is a lengthy and complex one and is

Ball Mill an overview ScienceDirect Topics

The ball mill is a tumbling mill that uses steel balls as the grinding media. The high degree of fineness achieved is the result of this long grinding procedure. Continuous feeding is carried out by vibrating feeders, rotary valves, or conveyor screws. The product is subsequently conveyed either pneumatically or mechanically. They are basically used to homogenize food and feed. CryoGrinder
