Abstract
A pulverizer which reduces solid materials having moisture content to a powder-like material in a single pass through the pulverizer. The pulverizer of this invention utilizes a plurality of radially extending flexible chains associated with anvils oriented outwardly and above the ends of the chains for disintegrating solid materials into fine aggregate material similar to dust or powder. The chains and anvils produce a kinetic energy and standing sound waves to fracture materials and vaporize moisture in the materials with the characteristics of the kinetic energy and standing sound waves being varied depending upon the structural characteristics of the rotatable chains and anvils, the spatial relationship between the chains and anvils, the angular position of the anvils and the rotational speed of the chains. Materials having overall sizes between 11/2 to 2 inches may be pulverized and reduced to a size to pass through a 200 mesh screen in a single pass and is capable of removing moisture from the material which has up to 60% of moisture by weight to produce a completely dry powder or dust-like material.
