the apparent difference in capacities between grinding mills (listed as being the same size) is due to the fact that there is no uniform method of designating the size of a mill, for example: a 5′ x 5′ ball mill has a working diameter of 5′ inside the liners and has 20 per cent more capacity than all other ball mills designated as 5′ x 5′ where the shell is 5′ inside diameter and

the media the ball mill consists of the mill base and the mill jar. there's one more important component to a ball mill, though: the media. the balls of heavy material which fall upon and crush the chemicals are called the milling media. here's the media i bought to use in this mill.

Calculate and Select Ball Mill Ball Size for Optimum Grinding

Calculate And Select Ball Mill Ball Size For Optimum Grinding

in grinding, selecting (calculate) the correct or optimum ball size that allows for the best and optimum/ideal or target grind size to be achieved by your ball mill is an important thing for a mineral processing engineer aka metallurgist to do. often, the ball used in ball mills is oversize “just in case”. well, this safety factor can cost you much in recovery and/or mill liner wear and tear.



the mill is used primarily to lift the load (medium and charge). additional power is required to keep the mill rotating. 8.1.3 power drawn by ball, semi-autogenous and autogenous mills a simplified picture of the mill load is shown in figure 8.3 ad this can be used to establish the essential features of a model for mill

The operating principle of the ball mill

The Operating Principle Of The Ball Mill

the operating principle of the ball mill consists of following steps. in a continuously operating ball mill, feed material fed through the central hole one of the caps into the drum and moves therealong, being exposed by grinding media. the material grinding occurs during impact falling grinding balls and abrasion the particles between the balls. then, discharge of ground material performed
