The current Polysius impact crusher range: identify wear parts, spares and maintenance tools by primary/secondary model, impact-circle diameter, rotor width and installation position.
PB crushers perform primary or secondary crushing of medium-hard to hard feed in stationary, semi-mobile or mobile arrangements. This page focuses on standard models, core dimensions, part positions, materials and technical checks needed for spare supply.
The table follows the thyssenkrupp Impact Crushers brochure: the first 11 entries are primary PB…CR models and the following 9 are secondary PB models. Throughput depends on material, product requirements and configuration.

Different positions face high-energy impact, repeated rebound, sliding wear or edge erosion. Each card links to shared component and material pages.
Blow Bar / Impact Bar
The main impact-crushing parts on the rotor perimeter. Confirm section, length, rotor slot, hydraulic clamping faces, rotation and mass matching against full PB model and rotor drawings.
View the common part page →
First Impact Apron Liner
Receives high-energy material thrown from the rotor. Check curvature, sections, holes, fastening and rotor clearance against housing and apron drawings.
View the common part page →
Lower Impact Face Liner
In subsequent impact and shaping zones, liners face repeated impact and sliding wear. Profiles, widths, overlaps and gap-adjustment relationships differ between stages and cannot be mixed.
View the common part page →
Side Liner
Protect rotor sides and housing walls while clearing the blow-bar sweep. Confirm left/right parts, holes, thickness, assembly sequence and access-door positions against installation drawings.
View the common part page →
Feed & Housing Liner
Cover feed impact points, housing walls and transitions. Check drop-impact and downstream sliding zones separately rather than assuming identical thickness and material.
View the common part page →
Rotor Protection Liner
Protect end discs and areas around blow-bar slots. Confirm end profile, sectors, holes, clamping clearance and dynamic-balance effects with the rotor assembly drawing.
View the common part page →Confirm drive and functional parts separately for dimensions and interfaces, loads, materials, heat treatment, flaw detection, machining and assembly.
Cast Rotor Assembly
Manufacturer records show mainshaft, separate cast rotor discs, end discs, blow-bar slots and clamps. Confirm diameter, width, disc stack, mass matching, dynamic balance and bearing interfaces together by PB model.
View the common part page →
Rotor Shaft
Passes through the discs and transmits the full impact torque. Confirm journals, steps, keys/connections, end fits, bending runout and bearing/coupling interfaces against original drawings.
View the common part page →
Rotor Bearing & Housing
Support heavy rotors under impact and unbalance. Confirm bearing designation, clearance, housing bore, end covers, seals, lubrication and left/right orientation against installation records.
View the common part page →
Hydraulic Gap Adjustment Cylinder
Provide preload, gap adjustment and overload release for impact surfaces and grinding paths. Check bore, stroke, mounting distance, pins, pressure, ports and seals as a set.
View the common part page →
Impact Apron Assembly
Includes frame, liners, pivot shaft, adjustment rods and hydraulic preload. Check frame dimensions, pivot centres, liner layout and gap range as an assembly.
View the common part page →
Hydraulic Wedge & Retaining Parts
The manufacturer uses hydraulic clamping to secure blow bars and simplify reversal/replacement. Confirm wedge angle, contact faces, hydraulic loading points, retainers and rotor slots together.
View the common part page →No. Confirm serial number, rotor design, blow-bar section and length, clamping wedge, rotation, drawing and revision.
Do not assume so. Impact energy, sliding wear, fracture risk, fastening and replacement intervals differ. Select materials separately by position and duty.
No. Throughput supports initial identification only. Manufacture requires full model, nameplate, drawing, measured dimensions or approved drawings.
Provide PB model, serial number, rotor dimensions, blow-bar section, apron, drawing, used-part photos, material and conditions for identification, material assessment, manufacture, quality control and delivery.
