  • How a Grate Discharge Ball Mill Works

    Here I try to explain how ground slurry is discharged from a grate ball mill (or SAG). How it works is the slurry flows across the grate as it would a screen panel. On the other side of the grate/screens are veins like a pump impeller. As the mill turns/rotates the slurry is "pumped" out and discharged. Discharge Grates The natural flexibility of rubber has allowed rubber manufacturers to the mill discharge from ball mill 1 will increase. With the same water addition to sump 1 the particle size of Cyclone 1 overflow will increase. This will decrease the ratio and hence the control loop will add more water to keep the ratio constant. However the amount of slurry reporting as fresh feed to the second milling circuit will increase.

    In ball mills steel balls or hard pebbles to break particle based on impact and attrition. A rotating mill charged with media and ore is lifted against the inside perimeter. Some of the media falls and impacts the ore particles at the bottom of the mill. The rest of the media cascades and in the process creates particle breakage by attrition. Discharge of pebbles finer rock ball scats and slurry from mills and its flow through trommels and into other processing operations has strong impacts on overflow ball mill performance.
