Consistent particle shape with reduced fines generation
The HAZEMAG HRC roll crusher is designed for the gentle crushing of soft to medium-hard materials and selected hard, brittle materials. It processes limestone, dolomite, marl, gypsum, coal, coke, phosphates and other suitable brittle feed materials. The machine is suited to industrial applications that require consistent particle shape, high throughput and reduced fines generation compared with impact or hammer crushers.
At the heart of the HRC are two counter-rotating rolls. Feed material is drawn into the crushing gap and reduced by compressive and shear forces. Hydraulic gap adjustment allows the product particle size to be adjusted. In the event of an overload, the hydraulically supported floating roll retracts automatically, widening the gap so that uncrushable foreign objects can pass through.
The HRC is used in mineral processing, the cement and building materials industries, and coal and coke processing. Its gentle crushing action produces a consistent particle shape with reduced fines generation compared with impact or hammer crushers.

Questions and answers about the HAZEMAG ROLL CRUSHER HRC
A roll crusher reduces material between two counter-rotating rolls. Feed material is drawn into the crushing gap and broken by compressive and shear forces. The HRC is suited to soft to medium-hard materials and selected hard, brittle materials, producing a consistent particle shape with reduced fines generation compared with impact or hammer crushers.
The HRC roll crusher is used for the gentle crushing of suitable feed materials where consistent particle shape and reduced fines generation compared with impact or hammer crushers are required. Typical applications include mineral processing, the cement and building materials industries, and coal and coke processing.
The HRC can process limestone, dolomite, marl, gypsum, coal, coke, phosphates and other suitable brittle materials. Suitability is assessed according to the feed material characteristics and the required size reduction task.
Product particle size can be influenced by adjusting the gap between the rolls. Hydraulic gap adjustment allows changes to be made during operation. The actual crushing result also depends on the feed material characteristics and roll configuration.
If an uncrushable foreign object enters the crushing gap and causes an overload, the hydraulically supported floating roll retracts. The wider gap allows the object to pass, reducing the risk of machine damage.
Yes. HAZEMAG provides genuine spare and wear parts and service support for the HRC roll crusher. Parts include toothed crushing segments, impact elements, hydraulic components, bearings and wear plates.
