Ball mills are usually either of the grate (diaphragm) or overflow type. Ball Mill Components. Ball mills consist of the following components: Inlet – crushed ore is fed to the ball mill through the inlet. A scoop ensures the feed to the mill is constant. Discharge – reduced feed exits the mill through the discharge.
Grate discharge ball mill: the ore is discharged through the grate plate. The grating part can strictly control the minerals' discharge size that meets the demand, it has a good effect on fine particle grinding. 3. Peripheral type: discharge ore through the periphery of …
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 0.2 to 0.3 mm. Grate discharge ball mill is usually applied in the first grinding system because it can discharge ...

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."
Gupta et al. (1981, 1982) have reported data measured on various ores in a 0.4 m 0.4 m pilot grate- discharge ball mill. In the 1981 paper the hold-up ms (kg of solid) was cor- related with Fs (solids feedrate) and ws (% solids) using a linear model of the form: ms = hlFs + k2ws + k3 While this model fitted their data well, it is clearly not ...
Grate 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.
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 ...
How a Grate Discharge Ball Mill Works 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.
Overflow VS Grate Discharge Ball or Mill Why Retrofit. 24/06/2015 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.
EB specializes in Grate Discharge Liner for Ball Mill for 20 years. The material includes ASTM A532, AS2027, BTMCr20Mo, BTMCr26Mo.
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.
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 over-grinding. 2040 Ball Mills. Ball Mills Brochure No.2040 06/02 24 ft. x 30 ft.- 14,000 HP Ball Mills . … The two most popular types of ball mills are…
