Closed circuit ball mill Basics revisited ScienceDirect

Apr 01, 2013· 1. Introduction. Over the years, ball mill circuits closed with cyclones have become an industry standard, and since the early days, it has been recognised that classification efficiency and circulating load both have a major effect on the efficiency of closed circuit grinding (i.e. its capacity to produce the desired final product).

Ball Mill Cyclone overflow P80. Grinding

I would like to know the effect of ball mill cyclone overflow density on P80 of 150um. I ask this because at either higher or lower densities, you can get your P80 @ 150um (at least 80% passing 150um). Kindly advise on what densities would you get the P80 best for floating c

High recirculating loads in Ball Mill Circuits Grinding

Why do ball mills have such high circulating loads?The ball mill grinds. The cyclones separate. But the pump neither grinds nor separates. So what is the purpose of having such a big pump to maintain high circulating loads in our grinding circuit?A recent grinding bulletin addresses this question f

Cyclonic separation Wikipedia

Cyclonic separation is a method of removing particulates from an air, gas or liquid stream, without the use of filters, through vortex separation. When removing particulate matter from liquid, a hydrocyclone is used; while from gas, a gas cyclone is used. Rotational effects and gravity are used to separate mixtures of solids and fluids. The method can also be used to separate fine droplets of
