More Information
Summary:The present invention provides a rock crusher tooth design which when exposed to material flows during operation of the rock/material crusher will increase the wear life of the tooth by resisting wear caused by a material flow acros s, onto, and around the tooth. It is a general object of the present invention to provide a rock crusher with a plurality of teeth formed integrally therein. The tooth has a design that significantly improves the wear resistance of each tooth. The tooth structur e includes a plurality of hard material compact inserts integrated within the tooth structure. The compact inserts are integrally formed with the teeth into unitary structures . In an embodiment of the invention, hard abrasive material, such as tungsten-carbid e compact inserts, are appropriately positioned in a steel cast tooth mold, th e steel flows into spaces between and around the tungsten-carbide inserts trapping them in a steel matrix. The casting method results in an integral unitary steel tooth.</SDOA B>
