comparison of power consumption in wet and dry ball mill

Ball mills operate between 65 and 80 solids by weight

• Wet grinding is generally used in mineral processing operations because of the overall economies of operation. Advantages include: 1. Lower power consumption per tonne of product, 2. Higher capacity per unit mill volume, 3. Making possible the use of wet screening or classification for close product control. 4. Elimination of dust problem, and 5.

Mills usually operate in the range 65 - 82% of critical but values as high as 90% are sometimes used. A crucial parameter that defines the performance of a mill is the energy consumption. The power supplied to the mill is used primarily to lift the load (medium and charge). Additional power is required to keep the mill rotating. 8.1.3 Power drawn by ball, semi-autogenous and autogenous mills

Review of Organic Binders for Iron Ore Agglomeration

• Binders help control transport of moisture during the wet agglomeration process. Binders increase the viscosity of moisture within the green-ball structure, and slow the transport of moisture from the green-ball interior to the green-ball surface. This phenomenon controls green-ball growth rates which depend on free moisture at the

Ball Mills

In general, ball mills can be operated either wet or 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 these ball mills because they are very effective material handling devices. Ball mills are rated by power rather than capacity.

For example, ball mills use large media, normally 1/2" or larger, and run at a low (10-50) rpm. The other mills, such as sand, bead, and horizontal, use smaller media from 0.3mm to 2mm, but run at a very high rpm (roughly 800-1200). High speed dispersers with no media run even faster rpm (1200-1800).
