Calculation of energy required for grinding in a ball mill. Int. J. Miner. Process., 25: 41-46. The Bond work index, Wi, as an indicator of the grindability of raw materials is not a material constant but rather it changes with change of size of the grinding product.
A ball mill is a type of grinder used to grind, blend and sometimes for mixing of materials for use in mineral dressing processes, paints, pyrotechnics, ceramics and selective laser sintering.It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. A ball mill consists of a hollow cylindrical shell rotati
grinding can be achieved at lower energy consumption. In ball mills, energy savings vary from 10 per cent to 40 per cent compared to 25 mm media. A regrind ball mill with a mix of small grinding media can be as energy effi cient as an Isa Mill charged with 2.5 and 3.5 mm beads. In vertical stirred mills,
Application: Energy saving mining ball mill is a key equipment in beneficiation plant.It is widely used in ore dressing production line such as Gold ore, Cooper ore, Magnetite ore, Antimony, Calcite, Kaolin, Mica, Clay, Bentonite etc Ferrou metal or Nonferrous metal materials.
The impact energy of the milling balls in the normal direction attains a value of up to 40 times higher than that due to gravitational acceleration. Hence, the planetary ball mill can be used for high-speed milling. Schematic view of motion of the ball and powder mixture.
Especific energy modelling SAG mills operation data abstract Comminution, particularly milling, is on average the largest consumer of energy in mining. Actual com-minution circuits consist in most of the cases in coarse crushing, SAG milling, pebble crushing and sec-ondary ball milling. In these circuits the SAG mill is the largest energy ...

Use this online calculators for Motor Sizing and Mill sizing as well as mill capacity determinators. In extracting from Process Machinery Reference Manual I will also provide 2 Ball Mill Sizing (Design) example done 'by-hand' from tables and charts. Today, much of this mill designing is done by computers, power models and others.
Material is fed into the gap between the rolls, and the crushed material leaves as a compacted cake. The energy consumption is 2.5–3.5 kWh/t and about 10 kWh/t when recycling of the material is used. The comminution efficiency of a HPGR is better than ball mills such that it consumes 30–50 % of the specific energy as compared to a ball mill.
