The particle size of imported materials is too large, causing insufficient output of the ball mill to throw stones excessively large particles will bring additional burden to the ball mill, and individual oversized particles are not easily crushed by the steel ball, which will cause the output of the ball mill to decrease and the power.
In continuous wet ball mills, the composition of feed (hard ore or soft ore) to the mill varies continuously, leading to uncontrolled grinding in the mill. in view of this, a new design of the discharge mechanism has been implemented to remove the ground particles of desired particle size fraction with minimum recirculating load (+150 m).the.
Benefits of tumble milling: 1. high efficiency – due to the relatively slow rotational speed but large mass of media, more of the energy goes into milling and less wasted as heat.. 2. narrow particle distribution – solids milled in tumble mills are normally so fine and consistent in size that it’s rare to require classification.. 3. repeatable results – mill operating parameters.
