Overflow VS Grate Discharge Ball or Mill - Why Retrofit
23-06-2015· 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 inBall Mills - Mineral Processing & Metallurgy,13-02-2017· Any overflow type mill can be easily converted to a grate discharge type by merely adding the improved grate head liners and theOverflow Versus Grate Discharge Ball Mills: An,,01-01-2015· The overflow mills use much simpler trunnion bearings to support the mill, whereas grate-only discharge mill would require a tire gear around the shell which is expensive and involves complex manufacturing process as the grate has to withstand the pressure exerted by the steel ball charge and allow slurry to discharge effectively."AMIT 135: Lesson 7 Ball Mills & Circuits – Mining Mill,,Three types of mill design are common. The Overflow Discharge mill is best suited for fine grinding to 75 – 106 microns. The Diaphram or Grate Discharge mill keeps coarse particles within the mill for additional grinding and typicallyOverflow Versus Grate Discharge Ball Mills: An,,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 their simplicity of design and production of finer product.Side effects of converting Ball Mill from Grate to,,First you will get a 10% reduction in capacity all else being equal just because the mills are now overflow mills. Second, the grates allowed the slurry level in the mill to be kept low at the low (26%) % full ball charge. Now the slurry level is higher and the balls have to fall through a lot of slurry to hit another ball. This dissipates energy.
