A hydrocyclone (often referred to by the shortened form cyclone) is a device to classify,separate or sort particles in a liquid suspension based on the ratio of their centripetal force to fluid resistanceThis ratio is high for dense (where separation by density is required) and coarse (where separation by size is required) particles,and low for ...

The aim of the ball mill/ hydrocyclone circuit is to produce the optimum flotation feed particle size while maintaining grind throughput. The optimal operating point is a tradeoff between throughput, recovery, and grinding cost.

In this case it is particle size. The cyclone underflow is directed to the ball mill for further grinding. Once the ore has passed through this mill it will be added back into the material that is being pumped to the cyclone for reclassification. The hydrocyclone product is the overflow, which of course is finely ground rock. It is this ...

HYDROCYCLONES By Richard A. Arterburn For many years, hydrocyclones, commonly referred to as cyclones, have been extensively utilized in the classification of particles in comminution circuits. The practical range of classification for cyclones is 40 microns to 400 microns, with some remote applications as fine as 5 microns or as coarse as 1000 ...

The mill control strategy has to compensate for these variations and minimize any disturbances to the hydrocyclone that is usually in closed circuit. The simplest arrangement is to setup several control loops starting from the control of water/solid ratio in the feed slurry, sump level control, density control of pulp streams at various stages ...

rougher head feed is a combination of multiple ball mill hydrocyclone overflows and, therefore, does not represent the performance of any individual ball mill circuit. Thus, the rougher head stream samples cannot be used in a ball mill control strategy for realtime particle size control. The online sampling system and ultrasonic particle size ...

The most common secondary mill is a ball mill in which relatively fine feed particles ( mm top size) are ground in a charge consisting predominantly of steel balls. Mills can be operated in open or closed modes (which refers to whether the product is size separated in some way with the oversize fed back into the mill).

Ball mill transport index control strategy. A simple ratio controller was implemented to regulate the solids content in the mill by manipulating the feed water. A calculated percent solid index is used to monitor the transport in the ball mill. A separate study was initiated to develop a measurement of this property (Bascur, 1985).
