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
Semi-autogenous mills are more common The AG Mill or SAG grinds primary crusher product and prepares it for final grinding in a ball mill Its product is usually passed over a large vibrating screen to separate oversize ‘pebbles’ from correct-size particl The correct-size material is sent forward to a ball mill for final grinding
Autogenous and Semi-Autogenous Mills - ScienceDirect
The designs of autogenous and semi-autogenous (SAG) grindings mills are described followed by the description of their methods of operation in grinding circuits involving crushers and ball mills Methods of estimating SAG mill volumes, mill charges, feed size and power consumptions and optimum speeds of rotation during operation are described
