Converting a ball mill from overflow to grate discharge

23/06/2020 In addition, the discharge rate of product from the grate discharge mill is higher and not dependent on mill feedrate. This combination of lower residence times and higher discharge rates in a grate discharge mill, coupled with the higher power draw and improved breakage rates, means that the throughput is higher in these mills for the same product size. However, the actual increase in

Overflow Versus Grate Discharge Ball Mills: An

In grate discharge mills the product is discharged primarily due to hydraulic gradient from the feed end to discharge end. Hence there is a possibility for much quicker transport of material through the mill, which is being accomplished in overflow mills by higher circulating load. Recent developments in understanding the importance of material transport in performance improvement of AG/SAG

Horizontal Grinding Mill Overflow Type, Grate-discharge

The grate-discharge type of Ball Mill has a grate at the outlet of the shell and causes less excessive grinding, compared to the overflow type. Therefore, generally, it is best suited to grind materials up to the particle sizes ranging from 60 to 100 mesh. Compartment type The compartment type of Ball Mill has a longer shell, inside of which is comparted into 2 to 3 chambers with grates and is
