WhatsApp: +86 18838072829Results obtained from the novel test are compared to piloting results using a UG2 ore. The steadystate and dynamic behaviour of semiautogenous grinding (SAG) mills are arguably best described using a population model that caters for the breakage kinetics and the material transport of rock and pulp inside the mill.
WhatsApp: +86 18838072829The grinding circuit comprises one 8530 mm diameter x 3650 mm semiautogenous mill driven by a 3954 kW variable speed dc motor, and one 5030 mm diameter x 8340 mm secondary ball mill driven by a 3730 kW synchronous motor. Four 1067 x 2400 mm vibrating feeders under the coarse ore stockpile feed the SAG mill via a 1067 mm feed belt equipped with ...
WhatsApp: +86 18838072829Mill heads are key structural components of any grinding mill. They must carry the load of the shell assembly, liners, media and material in process, and transmit it evenly to the trunnion bearings to assure smooth operation. Manufacturers in the "big mill business" have long ago recognized that simple extrapolation of existing designs from ...
WhatsApp: +86 18838072829In a autogenous mill the ore is fed directly into the mill from either the primary crusher or the mine itself. The size of the rock will be between four and eight inches. It will be this type of mill that will use a stock pile instead of a bin as fine ore storage. The feed is large enough that moisture and freezing won't bother it.
