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 . .
· •Close the SAG discharge grates from to inches. •Install a mm screen in closed circuit with the SAG mill discharge to treat Sandy ore. •Speed up the SAG mill to 75% speed since only 56% of the available HP was being used. •Leave the 5/8" trommel, ss will stop when the grates are closed.
The CenterPeriphery Discharge mill has feed reporting from both ends and the product discharges . Get Price; center peripheral discharge ball mill. Overflow VS Grate Discharge Ball or Mill Why Retrofit. The cost of a ball mill conversion from overflow to grate discharge is 'fairly' affordable at 65,000 for a 13′ x 15′ mill.
Grate Ball Mill Grate Type Ball Mill Grate Discharge Ball . Advantages of grate ball mill 1 As the ball mill transmission adopts rolling bearing instead of sliding bearings friction is greatly reduced with easy start up and significant saving energy 2 Its discharging end adopts cone design which not only increased the volume but also forcing grading of ball

recently reported that Codelco's El Teniente operation is the first mining company to use the latest version of 's PolyMet discharge grates for SAG mills. According to the company, implementation of this product was instrumental in enabling El Teniente to set a mine record for commercial production in 2015, with substantially lower operating costs.
The charge motion and breakage of particles inside the mill depends on the shell lifters design, while the discharge of ground particles is controlled by the grate and pulp lifters. The limitations imposed by poor grate and pulp lifter design become increasingly apparent with increasing size of ag/sag mills and their operation in closed circuit.
