A survey on troubleshooting of closed circuit grinding

ABSTRACT An industrial ball mill operating in closed-circuit with hydrocyclones was studied by five sampling surveys. The aim of the present study was to optimise operating parameters (i.e. charge volume, make-up ball size regime, slurry mean residence time, number of hydrocyclones in operation and hydrocyclone’s feed solids content (Sf)) with respect to increasing throughout from 225 to 300 ...

Batch Ball Mill for Open or Closed Circuit Grinding

The batch ball mill is a kind of ball milling machine which discharges the material in one time according to the nature of the material. Different from continuous ball mill, batch type ball mill grinds powder by times and adopts intermittent operation. The batch mill is mainly used for the mixing and grinding of materials, with uniform product fineness and saving power.ball mill manufactureres tanzania stone crusher machine.

Ball Mill Operation Grinding Circuit Startup amp Shutdown

Feb 01, 2016 The grinding circuit operator must ensure that the ball mill runs properly loaded and gives the correct ore grind. A major practical indication of mill loading is the sound made by the mill. A properly loaded mill will have a deep rhythmic roar, while an under loaded mill will have a metallic rattling type noise and an overloaded mill will be quite silent.

Grinding Circuit Overload Grinding amp Classification

If you need to add water to the feed end of your ball mill to control the density, by all means do so, but make sure you decrease water addition by an equal or greater amount elsewhere in the circuit (e.g. SAG feed or cyclone feed) or the overload will continue to escalate once the immediate benefits are overtaken by increased circulating load.
