ABSTRACT:
A single roll crusher for comminuting high purity materials includes a roll with teeth spaced around the circumference of the roll. The roll is rotatably mounted inside a housing. The housing has a top with an entrance port, sides, and bottom with an exit port. The roll, teeth, and at least the inside surfaces of the top, sides, and bottom are fabricated from a material of construction that minimizes contamination of silicon. The material of construction may be tungsten carbide with a cobalt binder. The single roll crusher is used for processing polycrystalline silicon.
