HAMMER MILL This mill comprises a set of hammers moving at high speed in a grinding chamber, which reduce the size of the grains until the particles are able to pass through a screen of designated size. Thus, the size and spectrum of particles produced depends on the screen size and the hammer speed (Koch, 1996).

3.1 Introduction. The unit cost of logging or road construction is essentially derived by dividing cost by production. In its simplest case, if you rented a tractor with operator for $60 per hour - including all fuel and other costs - and you excavated 100 cubic meters per hour, your unit cost for excavation would be $0.60 per cubic meter.

The hammer mill is designed to give the particles velocities of the order of that of the hammers. Fracture is either due to impact with the hammers or to the subsequent impact with the casing or grid. Since the particles are given high velocities, much of the size reduction is by attrition (i.e., particle on particle breakage), and this leads ...
