ball mill 2c length and diameter ratio

HPGR vs SAG

I think for SAG mill the load ball size will be one size. For reducing P80 this work must do Ball mill (secondary grinding) with small balls. We are load only 2.5' and this ball killed 1' ball. For more reducing P80 necessary use thirty grinding with Ball mill or Vertimill with load of 1.0'1.5'ball etc.

Cyclodextrins in Ball Milling

The aversion to ball mill assisted organic chemical reactions is principally laid in the relatively high (100) balls/reagent mass ratio, which makes the work-up size dependent, as we have demonstrated in a previous article [14]. Gram-scale preparations enabled the reagent/balls ratio to be reduced to a reasonable level.

8.3.2.2 Ball mills. The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter ( Figure 8.11).

The starting point for ball mill media and liquid charging is generally as follows: 50% media charge. Assuming 26% void space between spherical balls (non-spherical, irregularly shaped and mixed-size media will increase or decrease the free space) 50% x 26% = 13% free space. Add to this another 45% to 50% above the ball charge for total of 58%

How to improve the grinding efficiency of the ball mill

Jul 08, 2019Reasonable size and ratio of steel ball. Because the steel ball in the ball mill is in contact with the ore, and the ball diameter is too large, the crushing force is also large, which leads to the fracture of the ore along the direction of penetration force, rather than along the interface of different mineral crystals with weak bonding force

Jun 25, 2018L/D is the ratio of the length of magnetization direction of a magnet (L) to the diameter of the magnetization surface (D). For NdFeB magnets, L/D is of important reference significance for the preliminary judgment of the temperature resistance of the magnet. Under normal circumstances, we recommend an L/D of over 0.5 (preferably≥0.7).
