Standard Models and Key Dimensions
HAZEMAG Hammer Equipment Models and Key Dimensions
The table uses current official HAZEMAG HDS, HUM, HNM and HUV data. Capacity supports initial series screening; actual performance depends on feed material, particle size and configuration.

| HUM: 0703, 0705, 0708, 1008, 1013, 1313 | Single reversible rotor; Ø650–1,300 × 250–1,250 mm | Approximately 5–50 t/h at 95% below 3 mm; 15–250 kW | Hammers, rotor discs, grinding path, grate plates, casing liners and V-belt drive |
| HNM: 0703, 0705, 0708, 1008, 1013, 1020, 1313, 1325 | Twin non-reversible rotors; Ø650–1,300 × 250–2,500 mm | Approximately 10–190 t/h at 95% below 3 mm; twin-motor configuration | Twin-rotor positions, hammers and pins, grinding path, grate plates and bearing supports |
| HUV: 1013, 1020, 1313, 1622, 1626, 1630, 1634 | Variable single rotor; feed opening approximately 376–690 × 1,220–3,400 mm | Maximum feed size 120–280 mm; published capacity approximately 110–510 t/h | Rotor configuration, hammers, impact and grinding path, casing liners and drive interfaces |
| Legacy Series: Unirotor and Novorotor | OEM-listed predecessors of HUM and HNM respectively | Confirm legacy dimensions and configuration using the specific nameplate, year and drawings | Do not substitute current-series dimensions, hammers or rotor designs directly |
Hammer equipment does not share universally interchangeable parts. Before manufacture, check the full model, rotor count and rotation, rotor dimensions, serial number, drawing and revision, and installed parts.

Wear Parts
Hammers, Pins, Rotor Discs, Liners and Grate-Basket Wear Parts
Six component groups cover direct impact, load transfer, impact and grinding surfaces, and screened discharge. Each group links to materials and common part pages.
02
Hammer Pins, Shafts and End Locks
Hammer Pin & Retention Parts
Connects swing hammers to rotor discs while carrying alternating impact, bending and wear. Check diameter, length, end locking, disc spacing, hammer bore and removal direction.
View Part Details →
03
Rotor Discs, Spacers and Spacer Rings
Rotor Disc, Spacer & Ring
Rotor discs are arranged along the shaft to position the hammers and transfer loads; spacers and rings control disc spacing. Check disc count, thickness, hole pattern, shaft fit and axial location as a set.
View Part Details →
04
Centre Anvil, Impact Walls and Casing Liners
Central Anvil, Impact Wall & Housing Liner
The HDS centre anvil lies between the two rotors. HUM, HNM and HUV use impact surfaces and casing liners according to their designs. Installation positions, profiles and load paths differ between series.
View Part Details →
05
Grinding-Path Liners, Impact Bars and Spacer Bars
Grinding Path Liner & Spacer Bar
Provides secondary impact, fine crushing and product-size control. Presence, bar count, spacing and curvature depend on the specific HUM, HNM or HUV duty.
View Part Details →
06
Grate Bars, Grate Plates and Grate Baskets
Grate Bar, Segment & Basket
The HDS grate basket retains oversized particles and can be withdrawn with its frame for maintenance. HUM and HNM may use different grate plates or screens. Check openings, gaps, curvature, segmentation and supports.
View Part Details →Spare Parts
Rotors, Main Shafts, Supports, Drives and Grate-Basket Maintenance Parts
Drive components are listed separately. Check rotors, main shafts, bearing housings, pulleys, V-belts and grate-basket trolleys against the specific series and installation interfaces.
01
Rotor Assemblies
Rotor Assembly
HDS has twin rotors, HUM and HUV have single rotors, and HNM has twin non-reversible rotors. Identify each by series, rotor position, rotation, disc count, hammer arrangement and shaft-end interfaces.
View Part Details →
02
Rotor Main Shaft
Rotor Shaft
Transmits drive torque and carries hammer impact loads. Check shaft ends, bearing and seal seats, key or locking-assembly interfaces, disc-pack fits, rotation and dynamic balance requirements.

03
Rotor Bearings, Bearing Housings and Seals
Rotor Bearing, Housing & Seal
Supports the impact rotor and maintains shaft position. Check bearing designation, clearance, housing bore, end covers, temperature monitoring, seals and lubrication interfaces as a set.

05
Matched V-Belts and Tensioning Interfaces
V-Belt Set & Tension Interface
Confirm V-belts as a matched set by cross-section, effective length, belt count, matching tolerance, pulley groove profile and centre distance. Do not mix batches or replace only one belt.

06
Grate-Basket Trolley, Rollers and Guides
Grate Basket Trolley, Roller & Guide
The HDS grate basket can be withdrawn from the casing on its frame or trolley. Check rollers, rails, pins, stops and supports as a set against machine width and maintenance direction.

Frequently asked questions
Can HDS, HUM, HNM and HUV hammers be interchanged based on appearance?
No. Rotor count, rotation, disc spacing, hammer pins, swing clearance and operating conditions differ. Confirm each part against the full model, rotor position, dimensions, drawing and worn part.
Why are pulleys and V-belts listed separately?
They are part of the drive train. Dimensions, groove profile, belt count, matching and dynamic balance directly affect rotor operation, so they require their own identification details.
Which OEM model details are listed on this page?
The available material does not provide traceable catalogue numbers matched to specific models and positions. Numbers without catalogue, drawing or installation-record support are not published.
