Review 19 current HRC standard models and the legacy WB series, including capacity, roll diameter and width, tooth segments, scrapers, fixed and floating roll shafts, drives and hydraulic protection.
This page covers models, roll dimensions, component positions, mechanisms and materials relevant to HRC identification and spare-parts supply. Before manufacture, use the nameplate, full model, serial number, general arrangement, drawing or traceable worn part to confirm fixed or floating roll position, tooth profile, rotation and drive interfaces.
The table uses current official HAZEMAG HRC data, grouped into the 05, 06, 08, 10 and 12 series. WB is retained for identifying legacy installations.
| Series and Standard Models | Capacity / Maximum Feed Size | Roll diameter / width | Key Spare-Part Checks |
|---|---|---|---|
| HRC 05: 0505, 0507, 0510 | 200 – 400 t/h max feed 225 mm | Roller diameter 520 mm; Roller width 510 – 1,020 mm | Smaller shaft assemblies, tooth segments, scrapers and drive interfaces |
| HRC 06: 0605, 0607, 0610, 0616, 0620 | 300 – 1,200 t/h max feed 300 mm | Roller diameter 680 mm; Roller width 510 – 2,040 mm | Fixed and floating rolls, tooth segments, bearing housings and hydraulic protection |
| HRC 08: 0810, 0816, 0820 | 750 – 1,550 t/h max feed 400 mm | Roller diameter 850 mm; Roller width 1,020 – 2,040 mm | Roll-body length, tooth-segment arrangement, scrapers and drive configuration |
| HRC 10: 1010, 1016, 1020 | 850 – 1,750 t/h max feed 400 mm | Published roll width 1,020–2,040 mm | Full model, roll-body diameter, floating-roll mechanism and interface dimensions |
| HRC 12: 1210, 1216, 1220, 1225, 1230 | 1,050 – 3,100 t/h max feed 500 mm | Roller diameter 1,280 mm; Roller width 1,050 – 3,050 mm | Large roll shafts, tooth segments, rocker arms, hydraulic cylinders and drive base |
| Legacy Series: WB | Confirm legacy capacity and dimensions for the specific machine | Current HRC dimensions cannot be used directly as replacements | Check the nameplate, serial number, general arrangement, drawing and installed parts together |
The numbers on the diagram correspond one to one with the rows below.
| No. | Component | Location | Applies to |

| 1 | Crushing roll | Paired rolls inside open chamber | HRC |
| 2 | Drive assembly | Rear roll drive | HRC |
| 3 | Housing | Housing around rolls | HRC |
Five groups cover replaceable tooth segments, roll shells, side liners, bottom wear plates and adjustable scrapers. Materials are initial candidates; confirm them against drawings, worn parts and inspection requirements.
Replaceable Crushing Segment
HRC polygonal roll bodies carry replaceable crushing tooth segments. Tooth profile and count depend on the application. Check fixed or floating roll position, model, roll width, segment position, rotation and fastening method.
View Part Details →Roll Shell & Segment Carrier
This load-bearing structure supports the tooth segments and transmits torque. Check roll diameter and width, mounting interfaces, segmentation, keys or splines, end connections and dynamic balance requirements.
View Part Details →Side Liner & Side Plate
Protects the crushing-chamber sidewalls and areas beside the roll ends while limiting material escape. Profile, thickness, hole pattern, segmentation and fastening orientation depend on HRC model and roll width.
View Part Details →Bottom Liner & Discharge Wear Plate
Protects wear-prone areas below the rolls, on the bottom plate and near maintenance covers. The card uses the official HRC machine image to indicate the area; confirm individual sections against installation drawings.

Adjustable Scraper & Cleaner Blade
Removes material adhering to the rolls and keeps the crushing zone clear. The OEM states that scrapers can be adjusted and replaced individually. Check location, clearance, edge profile, supports and adjustment mechanism.
View Part Details →Check fixed and floating roll shafts, bearing housings, belt drives, connections, rocker-arm hydraulic protection and gap-adjustment parts as a complete system against installation interfaces.
Fixed & Floating Roll Shaft Assembly
The fixed and floating rolls have different support and relief functions. Check each roll position, shaft end, roll width, rotation, bearing seat, seal seat and drive connection separately.
View Part Details →
Bearing, Housing & End Seal
Supports both roll shafts while allowing the floating roll to move as designed. The card image is a generic identification reference. Confirm bearing designation, clearance, housing bore, end cover, seals and lubrication against the installation.
View Part Details →Drive, Gearbox & Coupling Assembly
The drive sits on a base connected to the crusher. The floating-roll drive moves with the rocker arm while maintaining belt tension. Check the motor, belt drive, reduction interfaces, couplings, rotation and mounting position.
View Part Details →Floating Roll Rocker, Cylinder & Torsion Shaft
The floating roll is mounted on pivoting rocker arms supported by hydraulic cylinders. A torsion shaft keeps the arms moving in parallel to allow uncrushable objects to pass. Check these components as a complete mechanism.
View Part Details →Gap Adjustment Wedge & Shim
Sets or corrects the crushing gap and compensates for wear of the crushing tools. Check adjustment method, location, thickness combinations, load-bearing faces, stops and control-system interfaces.
View Part Details →No. Confirm fixed or floating roll position, segment location, tooth profile, tooth count, rotation, serial number and drawing. The model only narrows the identification scope.
No. Check bore, rod diameter, stroke, mounting trunnions, pressure, rocker-arm interfaces, synchronisation between both sides and seal configuration.
Provide the full model, serial number, fixed or floating roll position, roll diameter and width, tooth profile, rotation, drawing, worn-part photographs and operating conditions. These support identification, material assessment, manufacturing coordination, quality control and finished-part delivery.
