How a Grate Discharge Ball Mill Works This mill type embodies the principle of steep pulp gradient. Quick discharge operation. A grate assembly at the discharge en d of the mill permits retention of a higher ball charge (up to 50%) than is possible in an overflow mill which has a .
Grate liners and ball mill liner The type of ball mill liner known as a grate liner is designed for discharge efficiency. It allows the discharge of ground materials via slots. With the Magotteaux range of alloys and their experience a longer lifetime and optimal grinding can be achieved.
has designed, manufactured and installed over 8,000 ball and pebble mills all over the world for a wide range of applications. Some of those applications are grate discharge, peripheral discharge, dry grinding, special length to diameter ratio, high temperature milling oprations and more.
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 reasons 2 Our grate discharge ball mill exported to more than 180 countries and regions, there are a lot of overseas offices and branches, you can rest assured purchase goethite high quality grate discharge ball mill installation grate discharge ball mill correct installation method is a good basis for operation of the machine can also be responsible for the entire production
The discharge end of the Grate Discharge Ball Mill has at least ten times the discharge opening area, through the grate slots, compared to the common trunnion overflow type mill. The discharge grates are designed to run clean and free of any blinding or choking. The pulp level in the mill may be varied by merely changing the pulp dilution.
Discharge 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. ...
【Type】 according to the discharge type, overflow ball mill, grate discharge ball mill; according to the grinding conditions, wet milling, dry grinding; according to the ball mill media. 【Wet grinding】 gold, chrome, tin, coltan, tantalite, silica sand, lead, pebble, and the like mining application.
The discharge opening is equipped with a discharge grate, and the ore pulp horizon of discharge opening is low. These two factors prevent ores from being overly grinded, and iron balls from being dismissed. Under same circumstance, the processing capacity of energysaving grate ball mill is bigger. Rolling bearings contribute enormous energy ...
Jan 01, 2016· Figure B indicates a mill where a diaphragm or grate is placed before the exit end so that particles greater than the openings of the diaphragm are not discharged but held back for further discharge mills give less excessive grinding compared to overflow mills and are best suited to grinds to 150–250 μm. In Figure C, the discharge opening is at the centre of the mill ...
Dry Ball Mill,Ceramic Ball Mill,Grate Ball Mill The grate ball mill is roughly composed of the cylinder, cylinder liner,big gear ring, discharging grate,and ore feeding there is a discharging grate.

Grate discharge ball mill Under the same condition, it has a higher capacity and can save more energy than other types of mills; It is better to choose a grate discharge ball mill when the required discharge size is in the range of to mm. Grate discharge ball mill is usually applied in the first grinding system because it can discharge ...
With grate discharge mills – typically SAG, AG and ball mills – the conventional relining process at the discharge end usually involves removing the dischargers and grates, replacing with new lined versions and hammering in large, long bolts through the layers to secure the liner components.
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 .
The ball mill can grind ores and other materials either wet or dry. There are two kinds of ball mill, grate type and overfall type, due to different ways of discharging material. Many types of grinding media are suitable for use in a ball mill, each material having its own specific properties and advantages.
ball mill grade discharge design benbbennekom. overflow discharge ball mill fitinline. grate discharge ball mill for dolomite newest design. The overflow type of Ball Mill is designed to overflow and discharge materials 2 to 3 chambers with grates and is best suited to produce products grinding from the processing capacity shows new feed rate ...
Jun 23, 2020· The grate discharge arrangement removes this slurry pooling effect almost completely. Estimates of the increases in power draw possible with grate discharge ball mills range from 10% to 20%, according to mill size and other operating parameters. The figures from pilot tests and some operating sites are even higher, up to 25% more power draw.
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,,
Here 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.
Grate Discharge Ball Mills Grates can be added to the discharge end of the ball mill to facilitate a steeper pulp gradient which helps to prevent overgrinding. 2040 Ball Mills Ball Mills Brochure 06/02 24 ft. x 30 ft. 14,000 HP Ball Mills . .
Nov 21, 2014· Overflow verses grate discharge ball mills: an experimental investigation ... Overflow Discharge Ball Mill in Operation Mineral Processing Duration: 1:42. Himanshu Srivastav 24,642 views.
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.
