2015-8-6 When you add water to the feed of the cyclone, the result is the overflow becomes lighter and the underflow becomes heavier. The heavier UNDERFLOW DENSITY will give the ball mill more work to do. This is reflected in a heavier density being fed back into the hydrocyclone feed pump box. Which again changes the hydrocyclone

2018-5-29 The hydrocyclone is an important device used in mineral processing beneficiation circuits for classification of mineral slurries by particle size. One input stream is separated into two output streams; an underflow of coarse particles that undergo additional grinding, and an overflow stream of finer particles that typically goes directly into a flotation circuit for recovery of the desired mineral. However, the hydrocyclone is a major piece of equipment in the beneficiation process that has no instrumentation for directly measuring its performance. The parameters currently measured – inlet pressure, feed flow rate, feed flow density – are common to the entire hydrocyclone cluster which has many hydrocyclones. Thus, no information is available to detect individual hydrocyclones that are operating poorly.

In this case, cyclone underflow is fed to a weired area in the underflow tub, and gravity-circuit feed taken from this area. Slurry excess to the capacity of the gravity circuit overflows back to ball-mill feed. For those circuits treating ball-mill discharge, a sluice can often be arranged to provide some preconcentration for the gravity circuit.

2015-6-1 The purpose of a mineral comminution circuit with a ball mill running in closed-loop with a hydrocyclone classification cluster is to feed the downstream process with the target particle size. Maintaining the optimal particle size in the flotation feed can significantly improve plant cash flow.

2021-1-4 uring the operation, the hydrocyclone operator also needs to regularly check the concentration and fineness of the overflow from the cyclone. The increase of overflow concentration or “overflow turning coarse” is usually caused by the increase of feed ore concentration and the blockage of the underflow.

2021-5-26 A typical mineral comminution circuit includes a ball mill running in closed-loop with a hydrocyclone battery. The job of the grind circuit is to reduce the size of the ore such that the downstream separation process can achieve the desired mineral recovery and quality while maintaining plant throughput and cost efficiency targets.
Read MoreThe entrainment of fine particles in underflow of a grinding-classification hydrocyclone can cause ore overgrinding, which will lead to reductions in both metal recovery and ball mill throughput. To address this problem, this paper proposed a W-shaped hydrocyclone that can effectively reduce underflow fine particle entrainment. Experimental tests and numerical simulations were employed to ...
