  • Estimation of the Specific Energy Requirement for Size

    118 Typically, the specific energy necessary to reduce the feed material to the desired product size varies in the range of 5–50 kWh/t. Therefore, it is important to have a sound methodology for design and scaleup of ball mills from the energy efficiency and productivity points of view.Molecules Free FullText Mechanochemical and Size ,1016 Planetary ball mill, 10 min: Size reduction from 0.24 mm to 0.015 mm, CrI, % reduction from 82 ± 2 to 39 ± 5: About 750 * Centrifugal Roller Mill, activation mode 600 rpm: Size reduction from 0.24 mm to 0.17 mm, CrI, % reduction from 82 ± 2 to 64 ± 2: 23: Centrifugal Roller Mill, activation mode 1200 rpm: Size reduction from 0.24 mm to 0.Tumbling Mills Size Reduction Beyond Discovery,510 Feed to ball mills can be as large as 2.5 to 4 cm (1 to 1a in) for very fragile materials, although the top size is generally 1 cm (a in). Most ball mills operate with a reduction ratio of 20 to 200:1. The largest balls are typically 13 cm (5 in) in diameter.

  • Modelling of the HighEnergy Ball Milling Process
