Grate Discharge Ball Mill Used in wet and dry grinding in both open and closed circuits, a grate discharge ball mill (sometimes known as a ‘diaphragm discharge mill’) incorporates a slotted discharge diaphragm with lifters at the discharge end of the mill.

More### 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. Discharge Grates The natural flexibility of rubber has allowed rubber manufacturers to

More### How a Grate Discharge Ball Mill Works

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 practical limit of around 40%. Behind the grates is a lifting compartment which picks up the ground material as it passes through the grates and transports it out of the mill. This quick removal of ground material

More### Improved Relationships for Discharge in SAG/AG Mills

there has been a shift of emphasis on ball mill optimization to semi-autogenous grinding (SAG) mills. In order to optimize this section, the skills to accurately model and understand its underlying mechanisms are required. The literature exposed a clear lack of previous research on the influence and performance of grate/pulp lifter design in AG/SAG mill discharge. The current understanding

01/09/2016· The lack of constraints in ball mill capacity in the published ball mill models may result in unrealistic predictions of mill throughput. This paper presents an overfilling indicator for wet overflow discharge ball mills. The overfilling indicator is based on the slurry residence time in a given mill and given operational conditions. Mathematical descriptions of the method to estimate the
