For example, as for the cylindrical grinding, some researchers set up the cylindrical traverse grinding force model on the basis of the analysis principle of the status of a single grinding grit. And some researchers analyzed grinding force by using the stress concentration theory and the mathematical statistics theory [4, 5].

Over the years, alternative procedures to the Bond grindability test have been proposed aiming to avoid the need for the standard mill or to reduce and simplify the grinding procedure. Some of them use the standard mill, while others are based on a nonstandard mill or computation techniques. Therefore, papers targeting to propose a better alternative claim to improve validity, to reduce test ...

Autogenous grinding is favored when the ore is quite competent and a fine grind is required. Semiautogenous grinding is applied when fine crushing could cause severe problems or when ore is variable in hardness or competency.

Fine grinding mills can be categorized into five groups [48]: impact mills, ball media mills, air jet mills, roller mills, and those of some other type, including disc mills. Impact mills and air jet mills are based on single impacts, as presented in Fig. 4 a, while ball media mills utilize double impacts between metal surfaces ( Fig. 4 b).

result in mills operating at optimum speed if low media charge or low consistency is used in the mill. The use of lifter bars welded or bolted to the mill cylinder in unlined mills reduces media slippage in mills whose rotational velocity is slow. Lifter bars are recommended when the grinding media charge is below 45 percent of the mill volume.
