jun 19 2015· if 75 percent of critical speed is considered desirable for efficient grinding in a 2.4 meter (8 foot) diameter mill then the same will be true for a 5.0 meter (15½ foot) diameter mill.
2.5 m lkl kw (8.12) kl is the loading factor which can be obtained from figures 8.5 for the popular mill types. 3 c is the mill speed measured as a fraction of the critical speed. more reliable models for the prediction of the power drawn by ball semi-autogenous and fully autogenous mills have been developed by morrell and by austin.

the ball load (9.5 kg) filled the mill to 45% of its volume. the feed charge was held constant at 874 g which occupied 80% of the void space between the balls at rest. for all experiments the mill was rotated at 65 rpm (60% of the critical speed). these conditions were selected because the net mill power draw under these
ball mill offered by us is used for grinding various products into fine particular sizes. this can be utilized for both wet grinding as well as dry grinding applications across the industry. our range includes cylindrical steel shell batch type ball grinding mill with flanged steel heads rotating on a horizontal axis. the
industrial ball mills use horizontal rotating cylinders that contain the grinding media and the particles to be broken. the mass moves up the wall of the cylinder as it rotates and falls back into the “toe” of the mill when the force of gravity exceeds friction and centrifugal forces.

the ball mill is a key piece of equipment for grinding crushed materials and is widely used in production of powders such as cement silies refractory material and glass ceramics as well as for ore dressing of both ferrous and nonferrous metals. ball mills can grind wet or dry and can be continuous or batch type mills.
ball mills are commonly used in the manufacture of portland cement and finer grinding stages of mineral processing one example being the sepro tyre drive grinding mill. industrial ball mills can be as large as 8.5 m (28 ft) in diameter with a 22 mw motor drawing approximately 0.0011% of the total world''s power (see list of countries by
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 ...
