Ask dr clark whitehopleman how to calculate raw mill grinding mediawe want to calculate theoratically the increase in raw mill output grinding in mid size vrm having capacity of 450 tph after reducing the mill feed size from your 1st chamber ball charge.
Ball mills are normally operated at around 75% of critical speed, so a mill with diameter 5 metres will turn at around 14 rpm. The mill is usually divided into at least two chambers (although this depends upon feed input size - mills including a roller press are mostly single-chambered), allowing the use of different sizes of grinding media.

A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints.Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles and stainless steel balls.
Creative Ball Mill's are generally operated in open or closed circuit grinding. Working principle: Creative Ball Mill works on the principle of impact on the Feed material and also due to abrasion of one ball over the other and by the free fall of the balls.
As the feed size is reduced further, less of the 50.8 mm balls and more of the 25.4 mm balls are required for the maximum capacity, attaining of 25.4 mm balls for a feed size of 4.7 mm (Fig. 6d). The capacity difference between the best and the worst make-up ball mixtures was as high as 150%.

Effect of Ball Size and Properties on Mill Grinding Capacity Current ball milling theory suggests that grinding capacity is influenced by the size of balls charged to the mill. In selecting the appropriate ball charge, the first objective is to determine that ball size which will grind the coarse particles most efficiently. This size should be the largest ball size charged to 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 ...

Ball mill is a cylinder rotating at about 70-80% of critical speed on two trunnions in white metal bearings or slide shoe bearings for large capacity mills. Closed circuit ball mill with two compartments for coarse and fine grinding and a drying compartment with lifters are generally found in cement plants for raw material grinding.
