Fine wood powders have advantages over traditional coarse wood particles for various emerging applications. However, an efficient system to produce fine wood powders has not been well established. We investigated the comminution capability and efficiency of a twostage grinding system consisting of a hammer mill circuit and an rotor impact mill circuit to convert wood feedstocks into fine powders.
Grinding in the disc mill is done between two roughly toothed grinding discs. One grinding disc is stationary, the other is rotated by a geared motor, thus exerting a shearing action on the material to be broken up. The gap between the two grinding discs determines the fineness of the material ground up. ... plugged fine coal right up to super ...
