The design of mill liners and sag mill discharge grates will have a large effect on how efficiently the mill operates and the circuit throughput. all models generally assume that a mill is fitted with efficient liners and that the grate design neither limits passage of pebbles (and pulp) nor permits re-circulation of pulp back into the.
The working principle of the sag mill and ag mill is basically the same as the ball mill machine, but the barrel diameter of the sag mill and ag mill is larger. the raw ore enters the ag mill through the feeding inlet, and the material is brought to a high place under the rotation of the barrel and then.
What's the difference between sag mill and ball mill. the working principle of theself-grinding machineis basically the same as theball mill, the biggestdifferenceis that thesag grinding machineuses the crushed material inside the cylinder as the grinding medium, the material constantly impacts and grinding to gradually.
