AMIT 135: Lesson 6 Grinding Circuit. Contents. Objectives; Reading & Lecture. AG/SAG Mills. ... ball mill or pebble mill. AG/SAG mills 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 of a ball mill. ... Single Stage SAG Mill.
SINGLE STAGE BALL MILLS Single stage balls add to the argument that rotary mills are not effi cient when processing large hard material. If a single stage ball receives material of 80 per cent passing 6 mm and larger, then the Bond oversize ineffi ciency factor EF4, will apply even if the material has rod and ball mill laboratory work indices as
Oct 12, 2017· Today we will learn about difference between sag mill vs ball mill. A mill is a machine by which solid or hard materials are broken into smaller pieces by means of grinding, crushing or cutting. This commutation is an essential part of many processes. Various kinds of mills are there with which different material processing takes place.
Low aspect mills are best suited to low-to-medium competent ores, while high aspect mills are more commonly used for competent ores either as single-stage circuits or autogenous-ball mill two-stage circuits. The larger diameter and short length provide better impact breakage for the competent ore.

The Advantages and Benefits of Hammer Mill: 1. Big reduction ratio: maximum feeding size is 1.3-1.5m, 3-150mm of discharging size. 2. High fineness of discharging size: favorable shape with aggregate, the powdery material is no more than 20%. 3. Simple process: the two or three stage crushing is reduced into single stage. 4.
In multi-stage ABC/SABC circuits, the AG or SAG mills are in closed circuit with screens and pebble crushers. The mill discharge from these mills consists of slurry, which goes to the ball mills for further grinding, and coarse pebbles/rocks, which are crushed and sent back to the mill.
Single stage crusher is suitable for crushing brittle ores with compressive strength < 150MPa, such as limestone, shale, gypsum, coal, argillaceous siltstone and mixture of limestone and clay. The bulk ore can be broken to the particle size needed by grinding at one time, so as to replace the traditional two-stage crushing, simplify the technological process and save the production cost.

3. Simple process: the two or three stage crushing is reduced into single stage. 4. Economical: small capacity of matched motor, which greatly reduces the production cost. The Working Process of Hammer Crusher: In the hammer mill machine, the motor drives the rotor to rotate at a high speed through the belt, and on the rotor there are series of ...
The comparison between single stage and double stage grinding has received much attention in the past few years. In order to submit information for use of mill operators, we have prepared comparative flowsheets for 50 Ton, 100 Ton, 200 Ton, 350 Ton and 550 Ton/24 hour plants, showing both single and two-stage grinding in typical mill flowsheets.
