In total 76 data sets were generated covering thepower draws of ball, SAG andAG millsin the range 7 - 7900 kW. All three models were found to predict thepower draw of the millsin the data ...

Ball Mill Design. A survey of Australian processing plants revealed amaximum ball mill diameterof 5.24 meters and length of 8.84 meters (Morrell, 1996).Autogenous mills rangeup to 12 meters in diameter. The length-to-diameter ratios in the previous table are for normal applications.

1 Calculation ofball millcapacity. The production capacity of theball millis determined by the amount of material required to be ground, and it must have a certain margin when designing and selecting. There are many factors affecting the production capacity of theball mill, in addition to the nature of the material (grain size, hardness, density, temperature and humidity), the degree of ...

AG/SAG millscan accomplish the same size reduction work as two or three stages of crushing and screening, arod mill, and some or all of the work of aball mill. Because of the range ofmillsizes available,AG/SAG millingcan often be accomplished with fewer lines than in a conventionalrod mill/ball mill circuit.

The maximum power draw in ball mill is when ball bed is 35-40 % by volume in whole empty mill volume. Considering that ball bed has a porosity of 40 %, the actual ball volume is considered to be ...

In general,ball millscan be operated eitherwetor dry and are capable of producing products in the order of 100 μm. This represents reduction ratios of as great as 100. Very large tonnages can be ground with theseball millsbecause they are very effective material handling devices.Ball millsare rated bypowerrather than capacity.

1. Introduction. In mineral processing plants, comminution circuits are the most energy consuming units; thus, determination ofmill power-drawcan be one of the most important factors for designing, operating and evaluating of an efficient plant , , .It was reported that for aball millwith 5 m diameter and 7 m length, thepower drawcan be between 2.5 and 3.5 MW, only 1–5% of this energy ...

Ball mills(wet)Ball mills, as described above, are also a machine of choice formillingsolids inwetphase. The design applied here is mainly aball millwith an agitator, the movement of the agitator making the beads move and impact or friction the particles to be milled.

Themillproduct can either be finished size ready for processing, or an intermediate size ready for final grinding in a rodmill,ball millor pebblemill. AG/SAGmillscan accomplish the same size reduction work as two or three stages of crushing and screening, a rodmill, and some or all of the work of aball mill.
