Autogenous Grinding & Semi Autogenous Grinding Circuits

Autogenous grinding is favored when the ore is quite competent and a fine grind is required. 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 FIELD: mechanical engineering. SUBSTANCE: invention relates to a device for grinding materials and namely to linings of semi-autogenous grinding drum mills and can be used in ball mills. The lining of drum mills is composite. It is made of base plates with protrusions and recesses. A central rib is made in the center of the base plate.Lining of semi-autogenous grinding drum mills Google Patents
