PRODUCT DESCRIPTION

HRC Roll Crusher
HRC Roll Crusher

For the industrial beneficiation of primary and secondary raw materials, crushing procedures for the production of certain grain sizes, forms, surfaces or for the outcrop of multi-component materials play a central role.

The utilised crusher must meet stringent requirements of today’s time when processing rocks, ores and coals. Materials to be crushed become more and more difficult in terms of handling, high throughput capacities are required and the energy input is a key focus. Therefore the application of energy-efficient roll crusher with high throughput rates becomes more and more important from the economic and ecologic point of view.

The HAZEMAG roll crusher meets these requirements and is characterized by the following points:

  • Low specific energy demand
  • High to very high throughput rate
  • Intelligent design with tramp metal protection
  • Automatic gab setting
  • Simple maintenance
  • High variety of crushing tools
  • Cubicle product with minimal fines
  • Trouble-free operation with very sticky and moist materials
  • Applicable for adhesive feed material
Operation
Operation

The operating principle is based on a continuous generation of pressure between two counter-rotating rolls, so that crushing takes place without interruptions in contrast to the intermittent jaw crushers. During operation, the high rotational energy of the crushing rolls and the drive components reduce the peak loads ideally and uniform power consumption is achieved.

If a non-breakable tramp metal enters the machine, it is essential to open the crushing gap to let the tramp material pass. This is achieved by using the so-called floating roll, which is supported in pivoting rocker arms. The rocker arms are supported by the lower housing via hydraulic cylinders. In order to guarantee parallel retraction of the floating roll, the rocker arms are connected with each other over a torsion shaft. The rotational reaction of the floating roll allows an almost frictionless movement and a great escape path.

Housing
Housing

Housing and drive bracket of the HAZEMAG Roll Crusher are very sturdy and thus suitable for heavy-duty applications. They are fitted with easy to exchange wear parts. The design of the housing allows a crushing segment changing below the feed hopper via easy dismountable hoods.

Drive Assembly
Drive Assembly

The drive is assembled on a base frame, which is connected with the roll crusher. The floating roll drive, also supported in pivoting mode, is connected with the floating roll rocker arm by a coupling rod. Thus it is ensured that a constant drive belt tension exists during the retraction movement of the floating roll, and during the adjusting of the gap.

Crushing Rolls
Crushing Rolls

The crushing rolls for primary and secondary crushers are made up of a roll body in polygon design which is equipped with exchangeable crushing segments. As a result of the specific geometry between roll body and crushing segment an optimum tight fit is achieved, thus being able to stand up to the high crushing forces. Depending on the respective task definition, the shape of teeth and their number are selected.

Application
Application
  • Ideally suited for the processing of soft to medium hard materials
  • Specific size reduction with a low generation of fines
  • Excellent solution when the raw material contains cohesive materials (clay) with a high moisture content
  • Designed with one fixed roll and one hydraulically adjustable floating roll – the reduction of the feed material is achieved by a combination of shearing and compression
