13-08-2015· 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.

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. The pulp level in the mill may be varied by merely changing the pulp dilution.
Therefore, no, changing to a grate discharge ball mill from overflow would not improve the situation. It would only cause the grates to pull with unground oversized rock chips/scats. I hope others here can complement this answer. Use the Social Share Bar on the Left.
The discharge of the ag/sag mill is fitted with a grate discharge where ground material passes through slotted apertures into a pulp chamber that then lifts the . get price 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.
Discharge Grates. Polycorp specializes in the design and manufacture of High Pressure Moulded Wear Resistant Rubber & PolyStl™ Grates. These grates are manufactured with moulded rubber on a steel frame and chord reinforcement to provide strength and flexibility to resist pressure and localized impact of the grinding charge.
01-01-2015· 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."
The performance of the pulp lifters in conjunction with grate design determines the ultimate flow capacity of these mills. Although the function of the pulp lifters is simply to transport the slurry passed through the discharge grate into the discharge trunnion, their performance depends on their design as well as that of the grate and operating conditions such as mill speed and charge level.
Grate-discharge Type 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

A set of experimental test work has been carried out in a continuous pilot ball mill of 0.41m X 0.56 m (diameter X length) at different mill speeds, percent solids and discharge mechanism. The results of study on material flow through a grate discharge tumbling mill verses an overflow tumbling mill are presented to emphasize the effect of discharge flow mechanism.

23-06-2020· If a mill has available power, conversion of the discharge arrangement from overflow to grate can be beneficial in allowing increased throughput or a finer product size. Conversely, if the mill does not have available power then it is still possible to install a grate discharge and to draw the same power by using a lower ball charge.
