What Are the Differences between Dry and Wet Type Ball Mill?

The water can wash away the fine particles in time to avoid over-grinding. The wet ball mill has a low noise, and low environmental pollution. The wet ball mill has a simple transportation device with less auxiliary equipment, so the investment is about 5%-10% lower than that of a dry ball mill. The grinding particle size is fine and uniform.

Axial mixing of slurry in an autogenous grinding mill

Austin et al. (1983) fitted the axial mixing model to data obtained from radiotracer tests done on laboratory and pilot scale ball mills. Recently, Powell and Nurick (1996) used X- rays to 'look' at the behaviour of the load in a perspex laboratory scale ball mill. They included some tests on observing the axial mixing of the grinding media.

The ball mills are often applied in mineral processing, they are e.g. an important part of the cement industry. A key factor, which influences the milling process, is the granular flow of grinding media. The flow determines: energy consumption, time of milling and capacity; thus there is a need to describe the phenomenon. The discrete element method DEM is a computational method, which allows ...
