Granulator

The Pennsylvania Crusher TKK Granulator is a ring hammer crusher. Rings suspended on pins strike the feed as the rotor turns and can rotate around the pins, distributing hammer wear. It combines crushing and sizing for brittle materials such as coal and coke.

Materials for similarly named parts may differ by OEM, machine model and operating conditions. Confirm the machine model, OEM drawing number and measured dimensions before ordering or manufacture.

Material Information

  • The OEM TKK specification lists ASTM A322 forged-steel toothed ring hammers. Confirm the material and heat treatment for the model and part drawing.
  • Ring hammer material must provide both impact toughness and wear resistance. Do not substitute a brittle material solely to increase hardness.
  • The OEM TKK specification lists AISI 1040/1045 carbon-manganese steel screen plates. Confirm alternative materials and repair procedures against the drawing and technical agreement.
