things a function of the grinding media size and the circumferential stirrer speed At similar ball mills The importance of stirred media mills increases steadily because of an increasing demand for fine and very fine particles and because of the advantages of relatively high pressure drop due to a very narrow gap width
High speed and High pressure Hazards Workers engaged in abrasive blasting can be struck by high speed particles from the blasting media or the surface being blasted substrate In addition they are exposed to high pressure hazards through contact with high pressure air or water streams uncontrolled high pressure hoses and air or water leaks
Ball mills can be lined with ceramics to reduce contamination from abrasive products but there is constant wear of the media which may contaminate the product Ball mills are often used in high volume mine mouth operations where cost ton has precedence over size distribution What particle size range does a jet mill nbsp

The ball mill is a tumbling mill that uses steel balls as the grinding media The length of the cylindrical shell is usually 1–1 5 times the shell diameter Figure 8 11 The feed can be dry with less than 3 moisture to minimize ball coating or slurry containing 20–40 water by weight
The mill heights can be varied to optimize the media load and power input for specific applications Chamber volumes range from 5 to 30 000 liters with corresponding drives from 5 to 5000 kW The HIGmill is the only ultrafine grinding technology in commercial use that can use small size high density grinding media in mill sizes above 3000 kW
