CRUSHING PLANT PROCESS OPTIMISATION P Svedensten1 ABSTRACT Design of processes in order to fi nd the most ef fi cient solution to a speci fi c task is a dif fi cult problem. Often the number of solutions are large and the optimal solution is therefore diffi cult to identify. Crushing plant process design is no exception from this statement.

Despite having these methods for underflow, like what you have said, most plants determine circulating load through material balance of some sub-fraction, the water, radioactive tracers. Back to my question with a simple case, the circulating load results through sub-fraction do not match with the results using water. It's like 310% vs 700%.

lation of the circulating load was achieved. At each iteration, the circulating load CL is calculated using the following equation: CL=∑n i=1 (p i.f i ) (2) Where fi is the flow (voul metric or mass) which feeds the i-th unit, an operational unit that contributes directly to the circulating load and pi is the flow partition in the same unit

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).

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.
