Roll Crusher

Only medium and large size particles are crushed. Small particles fall through the slots. The width of the crushing slots is adjustable. Typically 95 % of the crushed clinker has a partical size of less than 35 mm, depending on the size of the gap between the rolls. Each roll is driven by an electrical gear motor with planetary gear unit. While at normal operation the speed is fixed it may also be varied between 2 to 7.5 rpm. The crusher can either be located at the cooler discharge end to minimise installation and operating costs or can be installed as a mid-cooler crusher for intermediate crushing. Water cooling of the crusher shafts is an option for hot operation.

Advantages of the IKN Roll Crusher:

  • Large clinker lumps no longer stall the crusher.
  • Low circumferential roller speeds use less electric power and reduce wear and dust.
  • The rolls are electrically driven.
  • Rolls reverse upon high torque and protect the crushing rings against damage caused by foreign matter.
  • Narrow and uniform size distribution of the crushed clinker roll assembly is on rails for easy maintenance.
  • Roll teeth are hardfaced for long service life and easy re-facing - crushing rings are interchangeable.
