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. A well sized trommel should not let rocks pass to the Ball Mill if they are to be more than say 5/8″ or 16mm In the image case below, strangely enough, is the mill shell liner and discharge grate manufacturer. The grates it provides to this Cu/Pb ...

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 .
Ideally, the discharge rate through a gratepulp lifter assembly should be equal to the discharge rate through at a given mill holdup. However, the results obtained have shown that conventional pulp lifter designs cause considerable restrictions to flow resulting in reduced flow capacity.

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 (20100mm).
SAG Mill Circuit Example — Gold Processing SAG mill circuit example for gold processing [image: (13563)] AG/SAG Mill. AG/SAG mills are normally used to grind runoffmine ore or primary crusher product. Wet grinding in an AG/SAG mill is accomplished in a slurry of 50 to 80 percent solids. 2D and 3D simulations of particles in a SAG Mill
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 ...
SAG is an acronym for semiautogenous 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'' () in diameter, powered by a 28 MW (38,000 HP) motor.
SAG milling extends itself to many applications due to the range of mill sizes available. They can accomplish the same size reduction work as two or three stages of crushing and screening, a rod mill and some or all of the work done by a ball mill. SAG mills are also an optimum solution for wet grinding since crushing and screening in these ...
The apron feeders discharge on to a m wide conveyor belt which carries the ore into the mill grinding circuit. The primary grinding circuit consists of an m diameter × m grinding length, 5,222 kW SAG mill in closed circuit with a single deck vibrating screen and a cone crusher.

Grate Ball MillsGrinding Mill For Sale 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. This is only for the discharge head, grates and pulp filters (rubber).
We offer autogenous (AG), semiautogenous (SAG), ball, rod, and pebble mills in sizes ranging from kWs up to 30+ MW. Our product range also includes a number of unique solutions, including the world''s largest acidresistant grinding mills, which can operate with extremely corrosive slurry.
Discharge End Designs. Historically the grate discharge has been a design option in grinding mills. With the introduction of wet autogenous and semiautogenous mills, this type design is used exclusively. The discharge end of this mill must incorporate some method of conveying the pulp to the outside of the mill.

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