DESCRIPTION OF THE SAG AND BALL MILL CIRCUITS A conventional SAG and ball mill circuit (SABC) is used to treat material at a production rate of 30,000 t/d. The primary crusher product, having an 80% passing size of ~90 mm, is crushed and ground by the circuit to an 80% passing size of ~150 µm, after which it reports to rougher flotation.

The main drawback of SAG - high power consumption. To reduce power consumption, I think: 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.

Control of -SemiAutogenous Grinding(SAG) mill weight is an example of an important process that exhibits many of these aspects. Maintaining the SAG mill weight at the …

AG mills (or SAG mills with low ball charges) are often used in single-stage grinding applications. Based on their higher throughput and coarser grind relative to AG mills, it is more common for SAG mills to he …

Single stage SAG Mills are very beneficial in reducing CAPEX for plants with a staged throughput approach. When future tonnage is to be increased, the SAG Mill can feed downstream ball milling to boost capacity. Fuller …

The SAG mill (AG mill) has a large diameter and a small length. It looks like a flat round drum. The diameter of the SAG mill is generally about three times its length. The diameter of the hollow pivots at both ends of the barrel of a SAG mill is large. This SAG mill design can facilitate large-sized materials to enter the barrel smoothly.

Traditionally, the number of shell lifters used in a SAG mill is equal to twice the number of the feet in the mill shell diameter (e.g., a 34-ft-diameter mill shell would have 68 shell lifters). This is also called a 2-D shell lining. Eliminating some shell lifters increases the volume of charge between the lifters

Based on experience, mill-liner designs have moved toward more open-shell lifter spacing, increased pulp lifter volumetric capacity, and a grate design to facilitate maximizing both pebble-crushing circuit …

The main grinding circuit at Les Mines Selbaie consists of two mills, one SAG mill in closed circuit with an 8' x 20' vibrating screen with 700 micron deck, and one ball mill. The SAG mill is 8.23m (27') diameter x 3.75m (12.3') long. The Holt-McDermott grinding circuit uses a large primary SAG mill which is 5.03m (16.5') diameter x

SAG Mill Trommel Screen. 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. In the image case below, strangely enough, is the mill shell liner and discharge grate manufacturer. The grates it provides to this Cu/Pb/Zn operation are 15mm X 30mm.

The biggest characteristic of the sag mill is that the crushing ratio is large. The particle size of the materials to be ground is 300 ~ 400mm, sometimes even larger, and the minimum particle size of the …
