A centerless grinding machine is accurate, simple, and productive; in through-feed centerless grinding of bushes or pins, with a good work-piece feeding system, the work-pieces simply follow each other, enter the grinder, and comes out ground continuously. The machine eliminates the time wasted on clamping and de-clamping the workpiece.

This ball mill is typically designed to grind mineral ores and other materials with different hardness, and it is widely used in different fields, such as ore dressing, building material field, chemical industry, etc. Due to the difference of its slurry discharging method, it is divided to two types: grid type ball mill and overflow type ball mill.

The relative significance of corrosive and abrasive wear in ore grinding is discussed. Laboratory marked ball wear tests were carried out with …
