Get A QuoteThe pulp should have a volume of 18525456m3 in the ball mill Then the minimum grinding time 456135338min Note When the grinding time is the shortest grinding time it is ideal when the large block is directly ground to the granule size and there is no overgrinding phenomenon This value is only for theoretical calculation
For ball milling you can assume a porosity of about 035 to 040 the volume of space between the balls and you can normally assume the pulp surface level is equal to the ball charge surface level So do a crashstop and measure the volumetric filling of the charge then multiply that volume by 035 or 040
