MATHEMATICS OF GRINDING Critical Speed:-The "Critical Speed" for a grinding mill is defined as the rotational speed where centrifugal forces equal gravitational forces at the mill shell's inside surface.This is the rotational speed where balls will not fall away from the mill's shell. Mills are driven, in practice, at speeds of 50-90% of critical speed, the choice being influenced by economic ...

At standstill, the material inside the mill tends to solidify and stick to the mill shell. This is called frozen charge and could happen even within minutes, depending on the type of material processed. The detection of frozen charge is of significant importance in order to avoid major damage to the mill shell, bearings and liners.

Details Of Riding Rings For Rotary Kilns. The basic components of a rotary kiln are the shell, the refractory lining, support tyres and rollers, drive gear and internal heat exchangers.Tyres, sometimes called riding rings, usually consist of a single annular steel casting, machined to a smooth cylindrical surface, which attach loosely to the kiln shell.

The apparent difference in capacities between grinding mills (listed as being the same size) is due to the fact that there is no uniform method of designating the size of a mill, for example: a 5′ x 5′ Ball Mill has a working diameter of 5′ inside the liners and has 20 per cent more capacity than all other ball mills designated as 5′ x ...

The rods grind the ore by tumbling within the the mill, similar to the grinding balls in a ball mill. To prevent the conditions leading to rod charge tangling, the length to diameter ratio is maintained at 1.4 to 1.6. Rod mills accept feed up to about 50 mm (2 in.) and produce a product in the size range of 3000 to 270 mm (–4 to –35 mesh).

These studies have been important in a coordinated optimization program for mill heads, shells and trunnion bearings. Mill Shells require a similar but more complicated program for stress and deflection analysis. Often, depending on the load concentration and mill length, special shell designs are required. An example is shown on Figure 5.
