Get Morewhere the drop weight can be a steel ball or a plate. Narayanan (1985) used a ball shaped drop-weight in his breakage set-up to characterize chalcopyrite and lead-zinc ores ranging in size 9.5mm and 2.36mm. Andersen (1988), Man (2000) studied the breakage of 8mm ore particles by using the drop-weight apparatus developed at the
Get MoreThe pulp weight in the mill is obtained by subtracting the mill weight during the test from the empty mill weight, including the ball charge, at the start of the test. The pulp volume of the pulp in the mill is then calculated using the mill discharge density (before dilution) obtained during the sampling.
