The utility model implemented in COT (conveyor ore transportation) Mine "M" mining workshop, CDS-4 (crushing dumping station), SIC-270 (steep inclined conveyor). In 2013, in the amount of 254 teeth (labeled by mark 551.98.01.001) used in production, in 2014 - used in assembly - 596 pcs.
Task: improving the functional qualities of crusher, reducing the costs for teeth manufacturing, providing the protection of discs from wear and exception of premature failure the toothed disks due to breakage of the projections, providing the possibility for operational renewal the teeth directly in crusher. In addition, the exception of welding in renewal of quick-wear parts.
Character of the utility model: tooth of screw-toothed-roll crusher executed on the toothed disk in the form of projection which is coated. Cover executed as one piece crown and attached to projection by bolted connection. In such case internal seating surface of the crown reduplicate the shape of the projection.
