Controlled Size Reduction with Low Fines Generation
The HAZEMAG Center Sizer HCS is a specialised solution for the controlled size reduction of pre-crushed mineral materials. Instead of using impact forces, the system applies compressive and shear forces between two counter-rotating rolls. This produces a consistent particle size distribution while reducing fines generation.
The Center Sizer HCS is used wherever stable, repeatable crushing is required, for example in the cement and aggregates industries or in industrial raw material processing. It reliably prepares material for downstream screening, grinding or conveying processes.
The machine is designed for high throughput and smooth plant operation. Product size is adjusted by changing the roll centre distance or the effective gap. Its robust construction supports consistent results and high plant availability during continuous operation.
Your Advantages of the CENTER SIZER HCS
- Controlled Crushing: The HCS uses compressive and shear forces to produce a consistent, repeatable particle size distribution.
- Low Fines Generation: The roll-crushing principle produces significantly fewer fines than impact-based processes.
- High Throughput: Designed to process large quantities of material while maintaining continuous plant operation.
- Energy-Efficient Operation: Continuous compressive crushing results in low energy consumption per tonne.
- Robust Design: Durable rolls and wear-optimised components support reliable operation, including with abrasive materials.

Application Areas of the PRIMARY CENTER SIZER HCS
The HAZEMAG Primary Center Sizer HCS is used for the primary size reduction of mineral materials. Two counter-rotating rolls apply compressive and shear forces to the feed, producing a controlled product size with low fines generation.
Its design supports stable, continuous operation at high throughput. The crushed material can then be conveyed to downstream screening or further processing stages. The specific application and achievable product size depend on the material properties, feed size and plant configuration.
Typical Materials
- Mineral raw materials such as limestone, dolomite, granite, basalt, sandstone and shale, depending on compressive strength, abrasivity and the specific application
- Raw materials for cement and construction materials, such as lime, gypsum, clay and chalk
- Aggregates such as gravel and crushed sand for asphalt and concrete mixes

Further Information on the HAZEMAG PRIMARY CENTER SIZER HCS
The Center Sizer HCS is centred on low-energy, compressive size reduction. The roll crushing principle with controlled gap setting operates significantly more efficiently than impact-based systems – particularly with consistent feed materials.
Energy input can be precisely matched to material characteristics and throughput requirements. At the same time, reduced fines generation lowers the overall energy demand of downstream process stages.
Typical performance indicators (material-dependent):
- Low specific energy consumption through compressive crushing
- Reduced dust and noise emissions
- Continuous operation without high rotor speeds
The Center Sizer HCS is designed and manufactured in accordance with applicable European Machinery Directives and relevant statutory requirements. The enclosed machine design and well-accessible service areas support safe day-to-day operation.
Key features:
- Mechanical and electrical safety devices
- Clear separation of operating and maintenance zones
- Optional configurations for demanding operating environments
Its compact footprint allows the Center Sizer HCS to be integrated into existing processing plants with minimal effort. It is particularly well suited as a secondary crushing stage downstream of a primary crusher. HAZEMAG supports the full integration process from material feed through to conveying.
Typical process flow:
Primary Crusher → Center Sizer HCS → Screen / Conveying System
Interfaces:
- Mechanical: feed and discharge connections, transfer points
- Control system: integration into existing plant control systems
- Signals: operational status and condition monitoring outputs
The Center Sizer HCS is designed for low wear, long roll service life and low operating costs. Continuous operation can provide economic benefits over the machine’s full life cycle.
HAZEMAG can support application-specific cost analyses based on actual process data.
Key factors:
- Throughput
- Operating hours
- Material hardness and moisture
- Wear costs per tonne
Frequently Asked Questions – HAZEMAG PRIMARY CENTER SIZER HCS
A Center Sizer is a roll crusher for the controlled size reduction of mineral materials. It uses two counter-rotating rolls to crush the material to the required product size.
The Center Sizer HCS is primarily used as a secondary Center Sizer when consistent product gradation, low fines generation and energy-efficient operation are required. Typical applications include the cement industry, raw material processing and recycling.
Unlike impact crushers, the Center Sizer does not use impact energy. It reduces material through compressive crushing. This produces fewer fines, and energy consumption can often be lower for suitable materials and applications, particularly with consistent feed material.
The HCS is suitable for medium-hard to hard, brittle materials such as limestone, marl, clay, gypsum, coal and various industrial minerals. It can also process materials with varying compositions reliably.
The consistent roll gap supports repeatable results, low wear rates and smooth plant operation.
Yes, absolutely. HAZEMAG supplies a full range of genuine OEM spare parts for the HCS – roll segments, bearings, seals and wear components – backed by technical support directly from the manufacturer. Parts are also available through the HAZparts online portal.
