How Grinding In Sag Mill Done
Semi autogenous grinding (SAG) mills, because of their advantages in terms of capital and operating costs, were the natural choice for mines as their primary grinding mill option. Then, in the late 1980s when the price of copper rose quickly from a low of $0.62 lb to a high of $1.62 lb, this substantial increase in price further fuelled the.

The right determine of SAG feed size. This depends on the mill diameter and the ball size. Feed size necessary to take 80% of the maximum piece of ore that will crushed by the balls. For the big SAG more than 8 meters optimal feed size will be 50mm. Ball size 120 125mm. Do not a pebble crushing, the need secondary crushing.

SAG Mill Process Control Grinding & Classification
The purpose of a grinding mill is to convert electrical energy into rock breakage. The best use of that asset is to try to maximize the power draw. Try to hold the mill speed high and vary the feed rate to hold the weight (or bearing pressure), but watch out for "cycling" or "surging" that indicates instability in the charge.

How to Control a SAG Grinding Mill Circuit
Aug 05, 2017 Large grinding circuits normally require installation of 5 to 8 cyclones in a single cluster. Control of pressure drop across the cyclone is easily accomplished by providing one or more of the cyclones in the cluster with automatic valves so that they may be added to or deleted from the circuit as operating conditions dictate.

The grinding process reduces the rock to a slurry. The SAG mill is a large revolving cylinder. Rock is ground by the turning action of the mill, and impact from the hardened steel balls and the rock itself. In order to ensure that the rock is ground finely enough the SAG mill has a trommel screen (5), which acts like a large sieve.
