Autogenous Grinding Semi Autogenous Grinding Circuits
Semi-autogenous grinding is applied when fine crushing could cause severe problems or when ore is variable in hardness or competency. Figure 2 shows a typical conventional crushing-grinding circuit with three stages of crushing followed by ball mills or rod mill-ball mill combination.

SAG mills (semi-autogenous grinding mills) - Metso
Semi-autogenous mills or SAG mills, as they are often called, can accomplish the same size reduction work as two or three stages of crushing and screening. Often used in grinding at modern mineral processing plants, SAG mills reduce the material directly to the desired final size or prepare it for the following grinding stages.

In materials processing a grinder is a machine for producing fine particle size reduction through attrition and compressive forces at the grain size level. See also crusher for mechanisms producing larger particles. In general, grinding processes require a relatively large amount of energy; for this reason, an experimental method to measure the energy used locally during milling with different machines was recently proposed. A typical type of fine grinder is the ball mill. A slightly inclined or horizontal rotating cylinder is partially filled with balls, usually stone or metal, which grind material to the necessary fineness by friction and impact with the tumbling balls. Ball mills normally operate with an approximate ball charge of 30%. Ball mills are characterized by their smaller (comparatively) diameter and longer length, and often have a length 1.5 to 2.5 times the diameter. The feed is at one end of the cylinder and the discharge is at the other. Ball mills are commonly used in the manufacture of Portland cement and finer grinding stages of mineral processing, one example being the Sepro tyre drive Grinding Mill. Industrial ball mills can be as large as 8.5 m (28 ft) in diameter with a 22 MW motor, drawing approximately 0.0011% of the total world's power (see List of countries by electricity consumption). However, small versions of ball mills can be found in laboratories where they are used for grinding sample material for quality assurance. The power predictions for ball mills typically use the following form of the Bond equation: $${\displaystyle E=10W\left({\frac {1}{\sqrt {P_{80}}}}-{\frac {1}{\sqrt {F_{80}}}}\right)\,}$$where • E is the energy (kilowatt-hours per metric or short ton)
