  • Ball Mill Operation -Grinding Circuit Startup & Shutdown

    Another indication of mill loading is the power draw. Overloading and under loading will both reduce power draw. The ball mill must be run to draw maximum power at all times. The operator must manually measure the cyclone overflow and underflow densities regularly. An increase in overflow density is indicative of softer ore and will soon be accompanied by a lowering of power draw at the mill

    Ball Mills. Ball mills can be used for coarse grinding as described for the rod mill. They will, however, in that application produce more fines and tramp oversize and will in any case necessitate installation of effective classification. If finer grinding is wanted two or three stage grinding is advisable as for instant primary rod mill with 75—100 mm (3″—4″) rods, secondary ball mill with 25—40 mm(1″—1½”) balls and possibly tertiary ball mill with 20 mm (¾”) balls

  • Ball Mill an overview ScienceDirect Topics

    Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.-% ore and 25% steel. The ball mill is operated in closed circuit with a particle-size measurement device and size-control cyclones. The cyclones send correct-size material on to flotation and direct oversize material back to the ball mill
