Mar 14, 2007· Similar to the impeller design affecting pump capacity, the pulp lifter design affects the discharge capacity (or mill throughput) of autogenous grinding (AG) and SAG grinding mills. Generally, the discharge from AG/SAG mills consists of one or both of the following components: slurry (water and finer particles) and pebbles (20-100mm).

Similar to the impeller design affecting pump capacity, the pulp lifter design affects the discharge capacity (or mill throughput) of AG and SAG grinding mills. Generally, the discharge from AG/SAG mills consists of one or both of the following components: slurry (water and .

A SAG Mill trommel screen lets you control the true discharge size of your SAG mill or the transfer size to the downstream Ball Mill circuit.

SAG is an acronym for semi-autogenous grinding. SAG mills are autogenous mills that also use grinding balls like a ball mill. A SAG mill is usually a primary or first stage grinder. SAG mills use a ball charge of 8 to 21%. The largest SAG mill is 42' (12.8m) in diameter, powered by a 28 MW (38,000 HP) motor.

of grate/pulp lifter design in AG/SAG mill discharge. The current understanding from literature lacks knowledge of mill content size distribution and its effect on discharge through the grate at various aperture sizes and radial positions. It also indicates that in order to advance the understanding in a meaningful way, a more mechanistic ...

Developments in SAG Mill Design and Operation Over the last few years, SAG mill manufacturing technology has advanced rapidly. The bounds of mill size have been pushed from two directions. Firstly, the advent of ring motors has removed the constraint applied by the power that a .

the mill from the grates in the slot between the grates and the head. The oversize falls into a bucket wheel on the discharge end of the trommel, gets picked up as the trommel revolves and falls into the stationary rock box. A water jet then squirts that oversize back into the mill through the conical discharge .

SAG mill discharge control is quite involved due to few interactive variables, such as mill discharge sump level, classification hydro-cyclone variables (feed density, flow and pressure) and water feed rate to the sump. Model predictive control (MPC), which is a multi-input multi-output (MIMO) controller, is very suitable for this purpose. ...

SAG Mill - Mining engineering - Eng-Tips. 01.06.2005· Having been in a few process plants with SAG mills & they are inefficient- as low as 1% - since power costs are becoming a big issue there is lots of research being done ( try googling under SAG Mill efficiency) -technically I wouldn't consider them a 'crusher'- they are grinding mills and some mill people might take offence- note that SAG ...

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 ...
