The diameter of ball used will vary between 12 mm and 125 mm W o r k i n g The ball mill is used for the grinding of a wide range of materials and it copes with feed up to about 50 mm in size. The material to be ground may be fed in through a 60 degree cone at one end and the product leaves through a 30 degree cone at the other end.

· BACKGROUND The ball mill works on the principle of impact between the rapidly moving balls and the materials .Both the balls and the sample are enclosed in a hollow cylinder. At low speeds the ball rolled over each other and attrition takes place. 1,2 At critical speed the centrifugal force just occurs as a result the balls are picked up by the mill wall and carried nearly the top where that ...

· The present work aims at exploring the size reduction of γ-Al 2 O 3 using three mill types; single ball mill, air jet mill and planetary ball mill. In a similar manner to previous studies ( Zhou and Snyder, 1991 , Knozinger and Ratnasamy, 1978 ), X-ray diffraction (XRD) and Transmission Electron Microscopy (TEM) have been used to characterise the milled powders.

Get PriceCalculate 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 ...
