2020-3-26  Example of a (hydro) cyclone. When too much water is added to the process, more middle size particles are produced by the ball mill, so the cyclone overflow allows a lot of these middle size particles to escape the grinding circuit. This results in a decrease of material that the ball mill would have to grind, which lowers its efficiency.
