Cytec Handbook. Why have a large circulation load:. If a product all finer than a certain critical size is required, the capacity of the ball mill is increased considerably by using it in closed circuit with a classifier and this increase is made still greater by increasing the circulating load in between the ball mill and the classifier (Fig. 70).

(A plot plan of the facility is shown in Figure 1-2.) The coal crushing and grinding system consisted of a hammermill coal crusher, weigh-belt feeder, two ball mills (primary and secondary), and necessary hoppers, pumps, and conveyors. The mills were capable of providing coal over a range of grinds from a d{sub 50} of 125 to 25 microns.

Crushed ore was weighed by a Ramsey conveyor scale. Ore levels in the two fine ore bins were measured by Milltronics ultrasonic level devices. The grinding circuit was an automated operation in which the primary control objectives were to effectively control the particle size of the cyclone overflow product and maintain an optimum circulating load.

Summary: To achieve an optimum performance out of a closed circuit grinding system, the correct density regime of the hydrocyclones is of utmost importance and has to be adjusted to each systems´ requirement. One of the most important relationships for the optimization of the hydrocyclone recovery is the knowledge that the viscosity of the slurry increases with decreasing circulating load.

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.

A decision support system for equipment operation in a crushing circuit is proposed. ... However, if the amount of active equipment is greater than the optimum level, the excess circulating load ore and extra energy consumption reduce the circuit efficiency. In addition, the optimum amount of active equipment can change over time due to changes ...
