Keywords: Ball mills, grinding circuit, process control. I. Introduction Grinding in ball mills is an important technological process applied to reduce the size of particles which may have different nature and a wide diversity of physical, mechanical and chemical characteristics. Typical examples are the various ores, minerals, limestone, etc.
It is similar in operation to a SAG mill as described below but does not use steel balls in the mill. Also known as ROM or "Run Of Mine" grinding. SAG mill. Principle of SAG Mill operation. SAG is an acronym for semiautogenous grinding. SAG mills are autogenous mills that also use grinding balls like a ball mill.
The operating principle of the ball mill consists of following steps. In a continuously operating ball mill, feed material fed through the central hole one of the caps into the drum and moves therealong, being exposed by grinding media. The material grinding occurs during impact falling grinding balls and abrasion the particles between the balls.
SGS''s comminution experts use the SAG Mill Comminution (SMC) test to characterize ore samples, an important first step to grinding circuit design, optimization and production forecasting. The SMC test is an abbreviated, less expensive version of the JK Dropweight test.
