Overflow VS Grate Discharge Ball or Mill - Why Retrofit. A SAG Mill trommel screen lets you control the true discharge size of your SAG mill or the transfer size to the downstream Ball Mill circuit A well sized trommel should not let rocks pass to the Ball Mill if they are to be more than say 58″ or 16mm In the image case below strangely enough is the mill shell liner and discharge grate ...

Get PriceAfter the mill there would be a screen with 1mm opening, fines to spirals, coarse back to the mill. I used rod mills for such a coarse grind, but the handling of the rods is not as easy as if you use balls. So the question came up what a grate discharge ball mill would do here. I never used one. There are some comparisons available with normal ...

Get PriceDischarge grates play an important role in determining the performance of autogenous, semi-autogenous and grate discharge ball mills. The flow capacity (grinding capacity) of these mills is strongly influenced by the discharge grate design––open area and position of apertures, as well as the performance of the pulp lifters.

Get Priceand the Peripheral Discharge mill. Ball mills are built in Overflow and Diaphragm types. In the Overflow mill the material is discharged by new feed moving into the mill and displacing a mixture of solids and water being ground within the mill. The diaphragm arrangement in a ball mill is a positive means of pumping pulp or dry material out of the mill. The gradient is steeper than in an ...

Get PriceHere 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 ...

Get PriceGrate Discharge Ball mills with low pulp levels benefit from the full impact of the grinding media acting on the ore particles, as it falls into the shallow pulp. With a deep pulp level the grinding media is cushioned in the pulp, thus losing its energy and reducing its grinding ability. Grate Discharge Ball Mills have shown 25% to 45% more tonnage ground and a substantial reduction in power ...

Get PriceA ball mill is a type of grinder used to grind, blend and sometimes for mixing of materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. A ball mill consists of a hollow cylindrical shell rotating about ...
