Tertiary impact crusher with constant adjustment of the crushing gap

4 or 6 impact bars
hybrid setting

master

OLF’s MASTER impact crusher has been designed and built taking these basic parameters into consideration:

  • efficiency
  • versatility
  • economical operation
  • safety.

The rational and careful design has allowed to build a very simple, solid and reliable machine, whose maintenance is limited, easy and intuitive.

The construction is precise and careful, made with suitable materials, selected according to high quality standards.

use

This new machine finds its ideal location in all those quarries and mining industries where it is needed to crush to produce sand and quality thin materials in large amounts.

OLF directly installs its impact crushers, by its own specialized personnel. OLF ensures the correct testing, the operators’ training, the spare parts supply and the maintenance of the machines.

The off–the–shelf machine is equipped with special chrome alloy steel castings or, according to specific customer’s needs, with manganese steel, or other.

adjustments

The MASTER impact crusher is equipped with a 4 or 6 impact bars rotor, spinning alternatively in both senses. The adjustment acts on the rotor, whose rotation axis can be moved horizontally, adjusting the distance between the impact bars and the shell (crushing gap).

The adjustment, based on mechanical elements, is quick and easy and is executed by a crank handle device, checking on a proper millimeters bar the rotor displacement.

The rotor also allows a further radial displacement of the impact bars after the first working period, in order to optimize their wear.

A passive safety device allows to limit the damages, when metallic bodies accidentally came in the impact crusher.

standard equipments

  • arm with block and tackle and hand truck
  • support for the change of the impact bars
