Jun 23, 2020#0183;#32;The grate holds the balls inside the mill but allows the slurry to pass through, and it is then pumped out of the mill by the pulp lifters. This is different to an overflow mill which holds the slurry and balls inside until the slurry builds up to a level at which it is possible to overflow out of the discharge trunnion.
Overflow VS Grate Discharge Ball or Mill Why Retrofit. Grinding mills can by classified by which types of discharge the ball mill has installed to let out the ground slurry. Best is rapid change of mill content results in higher efficiency. Ball Mills have a very large discharge opening or area and smaller area for incoming feed. . Ball Charge and Grinding Efficiency

Overflow VS Grate Discharge Ball or Mill The cost of a ball mill conversion from overflow to grate discharge is fairlyaffordable at 65000 for a 13x 15mill This is only for the discharge head grates and pulp filters rubber A parison in laboratory of Overflow Discharge Ball Mill VS Grate Discharge Ball Mill. TECHNICAL NOTES 8 GRINDING R P King . of rotation respectively K is a calibration
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 their simplicity of design and production of finer product. In grate discharge mills the product is discharged primarily due to hydraulic gradient from the feed end to discharge
of rotation respectively. K is a calibration constant that varies with the type of discharge. For overflow mills K = and for grate mills K = This difference is ascribed to the presence of a pool of sl urry that is present on the bottom of overflowdischarge mills but not to the same extent in gratedischarge mills.

And the width of the grate holes on the orifice plate is 7 mm 20 mm. The ground ore passes through the grid plate along with the pulp. The grid plate near the side of the discharge end is equipped with an ore lifting device, which is a radial rib. The ribs divide the grid plate and the end cap into several fanshaped chambers leading to the hollow journal. When the grid ball mill rotates
I have lot of scats in overflow ball please help if I transformed overflow ball in grate discharge ball mill I will less scats production or not? (D80=10mm, P80=140 microns)
Overflow VS Grate Discharge Ball or Mill Why Retrofit. 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
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.
1/9/2016#0183;#32;An overfilling indicator for wet overflow discharge ball mills. It is not applicable for the grate discharge mill as their discharge mechanisms are different. The overfilling thresholds are an indicator that when a slurry residence time is shorter than the threshold, the mill is likely to be overfilled, and further increasing mill throughput should be carefully assessed, since none of the
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 type.

Overflow discharge mills are used when a product with high specific surface
ensp0183enspgrate discharge ball mill this type of mill usually works under high cycle load, so it produces very few extreme fines. Therefore, the unit power consumption is lower than that of overflow mill. Compared with overflow mill, the unit volume capacity of grate discharge mill
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,,
