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 gratescreens are veins like a pump impeller. As the mill turnsrotates the slurry is pumped out and discharged. Discharge Grates The natural flexibility of rubber has allowed rubber manufacturers to ...
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 ...

ABBs GMD is the most powerful mill drive system in the market to power semiautogenous SAG, ball and autogenous AG mills, This workhorse for grinding operations combines a robust, service-friendly and fit for purpose design to provide highest throughput, reliability
A ball mill is a type of grinder used to grind or blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering.It works on the principle of impact and attrition size reduction is done by impact as the balls drop from near the top of the shell. A ball mill consists of a hollow cylindrical shell rotating about its axis. T
A secondary, or ball mill, works a lot like a SAG mill except that it uses steel balls as the primary grinding media. It normally accepts material that passes through a 14-in. screen for hard ...
Autogenous grinding AG and semi-autogenous grinding SAG mills use the material to be ground as the grinding media. Autogenous grinding mills use larger rocks to impact and break smaller rocks as the mill rotates. Semi-autogenous mills are basically the same autogenous mills, but with the addition of balls, similar to those in ball mills.
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 AGSAG mills consists of one or both of the following components slurry water and finer particles and pebbles 20-100 mm.

What is SAG Semi-AutoGenous Grinding and How it works. ... most mill manufactures now include I their basic autogenous design the necessary strength for semi-autogenous operation. Ball sizing depends on the top size of the ore fed to the mill. Ball sizes commonly used
If the peripheral speed of the mill is too great, it begins to act like a centrifuge and the balls do not fall back, but stay on the perimeter of the mill. The point where the mill becomes a centrifuge is called the Critical Speed , and ball mills usually operate at 65 to 75 of the critical speed.
