Effect Of Ball Size And Powder Loading On The Milling

Effect Of Ball Size And Powder Loading On The Milling

Dec 01 2013 as the rotation speed rpm increases kinetic energy of the balls increases which in turn shifts the optimum ball size toward a smaller value because the negative influence is alleviated as the powder loading increases from 1 to 35 g at a given rotation speed rpm and ball size the milling efficiency decreases monotonically this phenomenon is interpreted to be resulted from 1 the
