2. Consider the following grinding circuit (a rod-ball mill circuit): 100 tph of dry solids are mixed with water to feed a rod mill in open circuit. The rod mill discharges into a pumpbox where water is added before feeding a ball mill. The ball mill discharge is pumped into a hydrocylone; the cyclone underflow circulates back to the ball mill and the cyclone overflow is …

Mineral processing, mineral beneficiation, or upgradation involves handling three primary types of ROM material, which have been blasted, fragmented, and brought out from an in situ position. These materials can be used directly or by simple or complex processing and even by applying extractive metallurgy like hydrometallurgical or pyrometallurgical methods.

How Much Circulating Load. In designing a closed-circuit crushing stage, the question of how much circulating load should be carried is a very important one. It not only has a direct bearing upon the capacity of the stage; it determines the amount of screening surface, and the elevating capacity necessary to handle the load in the circuit.

This is called the circulating load. By definition, circulating load equals the total feed to the crusher system with screens minus the new feed to the crusher. It is stated as a percentage of the new feed to the crusher. The equation for circulating load percentage is: R = 100/E/r-1 where R = circulating load, % E = screen efficiency, %
