Abstract: A two stage hammer mill which reduces recycled glass and its associated contaminants to small glass particles in the 100-800 grit size range and waste. The glass grinder is of light weight, modular construction, such that it may be taken apart, relocated, and restored to operation quickly and easily. A modular design also allows it to be easily cleaned and reconfigured to produce aggregate of selectable size. Located on separate rotors, installed in separate grinding chambers, the two hammer mills are spaced apart from one another and mounted within a common housing. The first stage provides a relatively coarse reduction of the material flow, which then passes into the secondary grinding chamber where the material is further ground. The design of the hammers in this hammer mill are such that they entrain a large quantity of air, accelerate it to high velocity, and drive the mixture of air and material through the system, entraining small, medium and large sized particles.

Abstract: The comminution of solid materials, such as stumps and wood waste, into particulate form is accomplished by introducing the material to be comminuted into a tub. The tub is rotated to induce a circular motion to the material.

Abstract: A series of screens for use with a size reduction machine have a tapered apertured wall formed into a frusto-conical shape, with an open wide end and a narrow closed end. All screens of a particular series have a cylindrical section, the same interior depth, outside diameter and angle of the tapered wall.

Abstract: An apparatus for separating fibers from a fiber aggregate comprises a hollow cylindrical apparatus housing defining therein a dissolving chamber. A partition is disposed in the internal space of the apparatus housing and forms the bottom of the dissolving chamber. The partition defines a plurality of through openings, through which fibers separated from the aggregate passes. The apparatus housing has an aggregate inlet to introduce the aggregate to be dissolved with pressurized air.

The partition is preferably formed with elastically or resiliently deformable material for absorbing impact upon the collision of the aggregate thereonto so as not to cause destroying of each individual fiber.

With the rings arranged so that the projections of adjacent rings abut each other, a still larger gap is obtained. This variable flow passage capability is further enhanced by varying the height of the projections.
