Semi-Autogenous Grinding (SAG) Mill. Wet or dry; Higher capacity than A-G mill grinding; Primary, coarse grinding (up to 400 mm feed size) a rod mill, and some or all of the of a ball mill. Because of the range of mill sizes availe, AG/SAG milling can often be accomplished with fewer lines than in a conventional rod mill/ball mill

1.27 for the rod mill and 0.67 for the ball mill. The particle size distributions reported are shown in Figure 1. It follows that the No 1 rod mill/ball mill circuit was operating very efﬁ ciently when comparing the combined operating inds for both mills with the rod mill and ball mill oratory inds.

The ball mill index oratory test is conducted by grinding an ore sample prepared to 100% passing 3.36 mm (6 mesh) to product size in the range of 45-150 µm (325-100 mesh), thus determining the ball mill index (Wi B or BWi). The index calculations across a narrow size range are conducted using the appropriate oratory

Dec 23, 2013· Autogenous mill is a self-grinding mill which is used in breakage of larger rocks. SAG (Semi-Autogenous Grinding) mill is an autogenous mill which uses grinding balls, it is similar to ball mill but has large diameter and short length. Vertical mill is used in grinding material at smaller particle sizes, which is used after ball mill.

drawn by ball, semi-autogenous and fully autogenous mills have been developed by Morrell and by Austin. (Morrell, S. Power draw of wet tumbling mills and its relationship to charge dynamics Part 2: An empirical approach to modeling of mill power draw. Trans. Instn. Mining. Metall.

A ball mill also known as pebble mill or tumbling mill is a milling machine that consists of a hallow cylinder containing balls; mounted on a metallic frame such that it can be rotated along its longitudinal axis. The balls which could be of different diameter occupy 30 50 % of the mill volume and its size depends on the feed and mill size.

The system considered is the large diameter-short length (D/L = 2) type of mill, which can be assumed to be fully-mixed in the axial direction, with a hold-up of W in a mill volume of V. Size distributions are expressed by a geometric sieve sequence (√2 or 4√2) numbered 1 for the top size interval, 2 for the next, etc., to n for the

Autogenous grinding (AG) and semi autogenous grinding (SAG) mills are . mill's response to operating parameters such as ball load, mill filling and mill speed . to the cost and risks of varying operating conditions on the full sized equipment. . continuous 600 x 250 mm wet pilot mill circuit is described by Mular et al (1988).

The first step in slag processing is size reduction to liberate metallic iron and iron-bearing minerals. This is done by crushers or by autogenous grinding, that is, the slag is ground on its own in the grinding mill without any balls. The latter process yields higher quality product as the iron product discharged from grinding mill contains as high as 80% Fe (Shen and Forssberg, 2003).

A Method of C alculating Autogenous/ Semi-Autogenous mills with the rod mill and ball mill oratory inds. Note, in Figure. 1, that the rod mill product slope is less than 0.5 due to an extra amount of nes present being ﬁ ﬁ ner than 650 μm. These ﬁ nes proceed to the ball mill improving the ball mill efﬁ ciency.
