### Ball Mill And Sag Circuit Mining Diagram

The working principle of the self-grinding machine is basically the same as the ball mill, the biggest difference is that the sag grinding machine uses the crushed material inside the cylinder as the grinding medium, the material constantly impacts and grinding to gradually pulverize. Sometimes, in order to improve the processing capacity of the mill, a small amount of steel balls be added appropriately, usually occupying 2-3 of the volume of the mill (that is semi-autogenous grinding).

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 materials to be discharged can reach 0.1 mm. The calculation shows that the crushing ratio can reach 3000 ~ 4000, while the ball mill 8217 s crushing ratio is smaller. The feed size is usually between 20-30mm and the product size is 0-3mm.

### What's The Difference Between Sag Mill And Ball Mill

Starting as small as 13 feet (4 m) in diameter on 330 HP and as large as 24 8242 (14.5 m) in diameter on 3,300 HP, the 911MPE Semi amp Fully Autogenous Mills tumble crushed ore without iron or steel grinding media. They are used when the crushed ore pieces are hard enough to perform all the grinding. SAG mills tumble mainly ore but they use up to 15 volume of steel balls to assist grinding. Semi-autogenous mills are more common.

### Ball Mill And Sag Circuit Mining In Bangladesh

The AG Mill or SAG grinds primary crusher product and prepares it for final grinding in a ball mill. Its product is usually passed over a large vibrating screen to separate oversize ‘pebbles’ from correct-size particles. The correct-size material is sent forward to a ball mill for final grinding. The oversize pebbles are recycled through a small eccentric crusher, then back to the SAG or autogenous grinding mill. This procedure maximizes ore throughput and minimizes electrical energy consumption.

### Mill And Sag Circuit Mining Diagram

The autogenous mill itself is a coarse-grinding device, consisting of tumbling drum with a 25 to 40 volume filling of ore. Metallic or manufactured grinding media is not used. Autogenous mills are fed run-of-mine ore or primary crusher product that is lt 25 cm (10 8243 ). Inside the mill, large pieces break into smaller pieces a few inches in size. These natural pebbles act as the grinding media the autogenous mill. The main modes of breakage are thought to be impact breakage and abrasion.

### Factors Affecting Sag Mill Perfomance

Many circuit configurations are possible, but essentially the autogenous or SAG mill is operated as a single-stage primary mill, or it can be followed by secondary pebble or ball milling. The semi amp autogenous mill is often operated in closed circuit with a trommel screen or external vibrating screen classifying the discharge. Circulating loads are low compared with those in ball mill circuits, because autogenous mills do not benefit from high-circulating loads in the same way ball mills do. Intermediate crushers are sometimes used to crush the largest pieces in the recycle stream.

### Ag Mills metso

The product size of an AG SAG mill depends strongly on the nature of the ore being ground so that tests must determine the competency of the ore and its “natural” particle size.

### Expert Mill Control At Anglogold Ashanti

Autogenous grinding implies by definition the grinding of ore by itself. Autogenous mills can be operated in tandem with secondary grinding mills (either a ball or a pebble mill) or they can be operated as single-stage mills in closed-circuit with a classification or sizing device. If a critical size builds up in the charge of the autogenous mill, it is usually extracted through pebble ports and crushed for recycle. Autogenous mills rely upon attrition grinding for their operation.

### Sag Mill Chute Design

Disintegration and size reduction of some ores is possible in tumbling mills without the aid of grinding media. Grinding mills in which comminution takes place without grinding aids are known as Autogenous Grinding (AG) mills or Fully Autogenous Grinding mills (FAG). These mills use large lumps of rock as the grinding media. Mills that use intermediate size rock or pebbles as a grinding medium are also autogenous mills but are known as pebble mills.

### Page 1 Page 2 Introduction Sag metallurgy omc

The disintegration and size reduction of ores in AG mills is brought about by a combination of impact, attrition and abrasion forces during mill rotation. Particles at the toe of the mill charge receive the maximum impact forces from falling rocks and other grinding media. Particles in the body of the mill charge partly slide from different heights and are subjected to attrition and abrasion resulting in size reduction.
