Calculate the reduction ratio of ball mill. At the finest grinding with a size reduction ratio of 1281 Fig 7d a 508 mm254 mm ball mix at a 1387 ratio was found to be the optimum mix This indies that the finer the product size the higher the proportion of smaller balls that is required. Live Chat
Calculation of reduction ratio in crushing [image: (13553)] Crushing Equipment The selection of the right crushing equipment is influenced by many factors some of which are upstream of the crushing plant ( blasting pattern and mining method) and others which are downstream of the crushing plant ( mill and grinding circuit selection).
For example, coarse crushers have size reduction ratios of below 8:1, while fine grinders may present ratios as high as 100:1. However, large reduction ratios, such as those obtained when dividing relatively large solid lumps to ultrafine powders, are normally attained by several stages using diverse crushing and grinding machines.
Peanut butter is a major product of peanuts (Arachis hypogaea L.) consumed worldwide. The concerns with additives in food products attract the demands for alternative natural peanut butter in market.
