While most grinding in the mineral industry is achieved using devices containing a steel grinding medium, the IsaMill uses inert grinding media such as silica sand, waste smelter slag or ceramic balls. The use of steel grinding media can cause problems in the subsequent flotation processes that are used to separate the various minerals in an ore, because the iron from the grinding medium can ...
terms of energy requirements and steel consumption related to grinding media and liners. Spherical grinding media are predominantly used in final stages of ore grinding. The spherical balls change shape through breakage and wear. Though this is universal in milling, its contribution and effect on milling kinetics, load behaviour and mill power

varied to optimize the media load and power input for specific applications. Chamber volumes range from 400 to 27,500 litres with corresponding drives from 132 to 5,000 kW (table 1). The HIGmillTM is the only ultrafine grinding technology in commercial use that can use small size high density grinding media in mill sizes above 3,000 kW. Table 1.
The working principle is simple; ... 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 .
Pin mill work by similar principle as hammer mills (impacts and shearing) but with typically faster tip speed rotor-stator configuration of intermeshing pins which impact the particles as solids are directed through the intermesh pins. The mill product leaves by centrifugal forces to the periphery and is then collected or further processed.
Working Principle The materials in tank are sucked into grinding chamber due to de negative pressure generated by high-speed rotation of the feeding device driven by the motor. The grinding discs drive the grinding medium inside the grinding chamber to do irregular movements in all direction to put the materials under the action of constant ...
