We discuss the types of ball mill, the basic principles of the ball mill, how it works, the details of design including equations for optimum dimensions in all cases, some manufacturers for the ball mill, and estimation of the cost the ball mill.6.1.Introduction ball mill is an efficient tool for grinding many materials into fine powder.
Of the balls is mainly in the direction of the rotation of the mill and not in the direction of the main axis.2.We consider a perfect layer structure.This means that the balls are lifted up in layers with distance of twice the radius of a ball and with the angular velocity of the mill.
Working principle operation.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.
