Grinding control strategy on the conventional milling

Grinding control strategy on the conventional milling circuit of Palabora Mining Company by B J du Plessis* Synopsis Automation of the conventional grinding circuits of Palabora Mining Company (PMC) required that adequate instrumentation and a control system had to be put in place after which extensive testing had to be done to evaluate different grinding control strategies The objective

calculation of grinding media for a ball mill

Calculation of Grinding Balls Surface Area and Volume Quite often there is a need for a quick and correct calculation of a grinding ball surface area and volumeNecessity of such calculations may arise when choosing a container for reloading grinding media into a ball mill when selecting the optimum characteristics of grinding ballsto suit

The grinding balls bulk weight in fully unloaded mill

Thus during calculating the grinding balls mass in ball mill (after measuring the mill filling degree with grinding media) needs to use the grinding balls bulk weight whose diameter was determined earlier In this case it may be differ from the grinding balls bulk weight loaded to the mill The formula for calculating the grinding balls mass in ball mill is given below (we will consider the measurements process and

CALCULATION OF THE POWER DRAW OF DRY

In this paper a new approach for the calculation of the power draw of cement grinding ball mills is proposed For this purpose cement grinding circuit data including the operational and design parameters were collected from 14 industrial ball mills ranging in diameters from 3 2 to 4 8 m The ball loads within the mills were measured by different methods proposed in the literature and power
