The Impact Crusher with swinging armor plates can be classified among hammer mills. However, it offers the following advantages in comparison to other hammer mills:

  • Less wear of armor plates and hammers
  • Less production of fine powders
  • Possibility of processing even moist raw materials without obstruction, as there is normally no grate
  • Possibility of feeding large-size raw materials (200÷500 mm)

Construction features

  • Casing of welded steel plate, fully protected by wear resistant steel plates
  • Large rotor with 4 hammers, cast in wear resistant chromium alloy or manganese steel
  • Very strong and compact construction
  • Very easy maintenance
  • Small overall dimensions
  • Possibility of adjusting the size of the product by varying the position of the armor plates and the speed
  • The machine cannot be obstructed by damp materials
  • The crusher can be supplied with special bar grate to obtain products with controlled granulometry (only for dry materials)
