The cost of a ball mill conversion from overflow to grate discharge is ‘fairly’ affordable at $65,000 for a 13′ x 15′ mill. This is only for the discharge head, grates and pulp filters (rubber). A comparison in laboratory of Overflow Discharge Ball Mill VS Grate Discharge Ball Mill.

Overflow Versus Grate Discharge Ball Mills: An Experimental Investigation It has been widely accepted to go for grate discharge ball milling when a coarse product is preferred or to avoid production of extreme fines, but overflow discharge mills are preferred for

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.

There are three principal forms of discharge mechanism. In the overflow ball mill, the ground product overflows through the discharge end trunnion. A diaphragm ball mill has a grate at the discharge end. The product flows through the slots in the grate.

Furthermore, The Ball Mill of a large capacity has been available to a very extensive range of applications in both dry and wet processing. Features. Overflow Type The overflow type of Ball Mill is designed to overflow and discharge materials from the trunnion on the outlet side.

The mill product can either be finished size ready for processing, or an intermediate size ready for final grinding in a rod mill, ball mill or pebble mill. AG/SAG mills can accomplish the same size reduction work as two or three stages of crushing and screening, a rod mill, and some or all of the work of a ball mill.

The pulp of Xinhai wet overflow ball mill overflow automatically, without forced discharge, which reduces the equipment wear and energy consumption, the discharging particle size is small, the qualified rate of grind size is improved, at the same time costs is under control.

For overflow ball mills, the charge should not exceed 45% of the mill volume . For grate discharge mills, the charge should occupy about 50% of the mill volume . Bond developed a relationship that can be used to determine the percent charge by volume as a function of the vertical height above the charge, He, and the radius of the mill, R, i.e.,

Grate discharge Dry Grate discharge Wet Overflow discharge Wet Figure 8.5 Effect of mill filling on power draft for ball mills. The data is taken from Rexnord Process Machinery Reference Manual, Rexnord Process Machinery Division, Milwaukee, 1976 The effect of varying mill speed on the power drawn by the mill is shown graphically in Figure 8.4

Grinding control strategy on the conventional milling circuit With the increase in ratio set point, a decrease in Cyclone 1 particle size is required. This control loop will increase the water to the sump to cause a decrease in cyclone overflow particle size. Circulating load control The only manipulated variable available in the closed milling
