TOOTH FOR ROLLER CRUSHER

摘要

An improved tooth for a roller crusher is presented. The tooth can include a first tungsten carbide overlay layer plasma-transfer arc welded on a recessed hemispherical end of the tooth, which is covered by a wearable cap placed over the first overlay layer, the cap welded to the tooth. A second tungsten carbide overlay layer can then be plasma-transfer arc welded over the cap to, thereby, provide a tooth having two tungsten carbide overlay wear layers.
