Grinding Mills and Their Types – IspatGuru

Vibratory mill does not rely on rotation for the main grinding action. The vibrating mill has a grinding chamber which is filled to around 65 % to 80 % of its capacity with grinding media such as balls or rods. The chamber is vibrated at a frequency of between 1000 and 1500 times per minute (can be variable speed) by cams or unbalanced weights.

solving: DP = 900 kg of oven-dry fiber per tonne of pulp. Formula 2 gives 45 = (900 kg / DW) * 100 solving: DW = 2,000 kg oven-dry wood per tonne of pulp. Here the yield of bleached kraft pulp is assumed to be 45% (Figure 8-1). Formula 3 gives 2,000 kg = V * 0.42 * 1,000 kg/m3 solving: V = 4.76 cubic meters of green wood per tonne of pulp.
