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).

The Operating Principle Of The Ball Mill. Feb 08, 2017 Therefore, the work of the mill with partial load conditions is unprofitable. Energy consumption for ball mills is a function of many factors the physical properties of the ground material – its specific gravity and hardness the degree of drum filling by grinding balls the number of drum rotations, etc. Ball mills have low efficiency.

A problem for solving mass balances in mineral processing plants is the calculation of circulating load in closed circuits. A family of possible methods for the resolution of these calculations is the iterative method, consisting of a finite loop where in each iteration the initial solution is refined in order to approach the exact solution.

Actually with the re-circulating load of about 250-300%, your operations are fine on the ball mills. You only experience high re-circulating loads if there is a change in the material being treated meaning the Bond work index tends to be higher for the new material.

Circulating load ratio is enormously important to grinding circuit efficiency. Diminishing returns dictate optimum economic operational values of. approximately 350% to 400% for most primary ball milling circuits. [6] Slide 6. f effective factors for circulating load.
