A grinder having with a rotor and fan assembly mounted in a housing having one or more of the following features: Cutting shaft and fan shaft concentric and rotated by separate motors, housing formed in two sections with a line of division passing through the axis of rotation and mounted on rollers, ping pong shaped cutting hammers, deflectors attached to the inside of the housing and to a deflector assembly on the outside of the housing. The deflectors movable vertically and horizontally with first and second motion controllers for adjusting the spacing between the cutting hammers and the deflectors. A programmable logic controller for independently controlling the speed at which the cutting shaft and fan shaft are rotated and the spacing between the cutting hammers and the deflectors to produce a desired particle size reduction for a selected material. |
