Size reduction is a process of reduction of material to smaller pieces to coarse particles or to powder/fine powder. Size reduction process is also known as Comminution and Grinding. When the particle size of solids is reduced by mechanical means it is known as Milling. The size reduction operation can be divided into two major categories depending on whether

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.
