### Overflow VS Grate Discharge Ball or Mill Why Retrofit

Allow me to compare: Ball mills can be of the overflow or of the grate discharge type Overflow discharge mills are used when a product with high specific surface is wanted, without any respect to the particle size distribution curveOverflow discharge mills give a final product in an open circuitHere 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 How a Grate Discharge Ball Mill WorksOverflow 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 Overflow Versus Grate Discharge Ball Mills: An

### Horizontal Grinding Mill Overflow Type, Gratedischarge

Gratedischarge Type The gratedischarge 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 type342019 Ball Mill, Grate Discharge, Toll Processing Ball Mill, Grate Discharge, Toll Processing Skip navigation Sign in Search Loading Close This video is unavailable Watch Queue Queue Watch Queue Queue Remove all; Disconnect; The next video is starting stop Loading Watch QueueGrate Discharge Grinding Mill YouTubeGrate Discharge Ball Mills have shown 25% to 45% more tonnage ground and a substantial reduction in power consumed per ton of material compared size for size with overflow mills To illustrate the characteristics of various type mills we have shown the types of discharge for rod mills and ball millsgrate discharge ball mill stalbonl

### Slurry flow in mills: grateonly discharge mechanism

Discharge grates play an important role in determining the performance of autogenous, semiautogenous 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 liftersThe mill discharge from these mills consists of slurry, which goes to the ball mills for further grinding, and coarse pebbles/rocks, which are crushed and sent back to the mill To maximize the capacity of these circuits, the general practice is to use grates with pebble ports (reaching 100 mm) instead of normal grate openings to increase the pebble removalOptimizing your SAG mill operation International MiningCalculate Ball Mill Charge how to calculate the ball mill discharge size distribution Millspeed Sliderule Pipe Launder Liner Height Mill filling Estimates the charge volume of a grinding mill based on the number of exposed lifters By counting the number of lifters showing (during a mill shutdown) and comparing to the total number of ball mill discharge launder mamacafedelftnl
