ball mill crushing . high crushing mill and ; ball mill crushing by tube-mills were first introduced into the crushing departments of cyanide plants when it was found that for crushing finer thanmesh other types of crushing machinery were not efficient. in order to crush with one pass, these mills were madetoft. 5.to.m. in length. pebbles were used as a grinding medium and the mills were lined
the energy efficiency of ball milling in comminution. at low reduction ratios being grinding unconfined particles in a ball mill. at higher reduction ratios, the fine particles in the product lead to a retardation effect in particle beds, under which conditions the ball mill becomes more energy-efficient than particle-bed high-pressure
ef6 - high or low ratio of reduction rod milling - the equation to be used, unless: rr = rro ± 2. l = rod length. this factor generally applies to low ratios of reduction, but its application to high ratios of reduction does not always apply and should be used only if the wioc ÷ wi grinding efficiency factor indicates that it should be used.
