Identify models, principal dimensions, wear parts and drive spares for legacy and current ERC installations. FLS now carries this mining product line.
ERC combines a static grizzly and eccentric-roll primary crusher in a compact frame. This page covers models, dimensions, part positions, material links and enquiry requirements for spares; project capacity figures are not universal manufacturing specifications.
The table follows the five standard models in the thyssenkrupp ERC brochure. Capacity varies with material, feed grading and CSS. Manufacture requires full model, serial number and drawing revision.
| Standard model | Roll diameter / width | Feed opening and discharge setting | Installed power / reference weight |
|---|---|---|---|
| ERC 18-14 | Diameter 1800 mm / width 1400 mm | Feed opening 1000 mm; CSS 100–220 mm | 160–300 kW; approx. 83 t |
| ERC 22-20 | Diameter 2200 mm / width 2000 mm | Feed opening 1200 mm; CSS 120–260 mm | 300–450 kW; approx. 138 t |
| ERC 25-25 | Diameter 2500 mm / width 2500 mm | Feed opening 1280 mm; CSS 120–260 mm | 450–600 kW; approx. 185 t |
| ERC 25-30 | Diameter 2500 mm / width 3000 mm | Feed opening 1280 mm; CSS 140–300 mm | 500–700 kW; approx. 215 t |
| ERC 25-34 | Diameter 2500 mm / width 3400 mm | Feed opening 1280 mm; CSS 140–300 mm | 600–800 kW; approx. 240 t |
The numbers on the diagram correspond one to one with the rows below.
| No. | Component | Location | Applies to |
|---|---|---|---|
| 1 | Roll shell | Working face of the large-diameter roll | ERC OEM family section (dimensions not specified) |
| 2 | Jaw liner | Fixed crushing face on the left of the roll | ERC OEM family section (dimensions not specified) |
| 3 | Eccentric roll assembly | Central eccentrically rotating assembly | ERC OEM family section (dimensions not specified) |
| 4 | Grizzly screen | Prescreening zone at the inlet | ERC OEM family section (dimensions not specified) |
| 5 | Hydraulic relief mechanism | Relief assembly beneath the jaw side | ERC OEM family section (dimensions not specified) |
Identify roll liners, segments, counter jaws, grizzly bars and side liners by impact and wear location. Each card links to the relevant component and material pages.
Roll Liner / Crushing Element
Mounted around the eccentric roll, these form the chamber with the counter jaw. Confirm diameter, width, segmentation, fixing interfaces and wear profile against the full ERC model and installed drawings.
View the common part page →
Roll Shell Segment
Segments surround the roll. Eccentric motion and slow reverse rotation distribute wear around its circumference. Check segment count, circumferential position, fixing holes and adjacent interfaces together.
View the common part page →Fixed Jaw / Counter Jaw
Opposite the roll, the jaw forms a continuous crushing gap. Its curvature, thickness, supports and hydraulic-setting interfaces depend on model and wear-compensation position.

Integrated Grizzly Bar
The static grizzly above the chamber bypasses fines. Confirm bar gaps, length, orientation, supports and replacement interfaces for the model and target feed grading.
View the common part page →Side Liner / Cheek Plate
These protect chamber sides and adjacent housing. Similar appearance does not establish compatibility of profiles, thickness, countersunk holes, edge overlaps or left/right parts.
View the common part page →Feed / Discharge Area Liner
These cover feed impact points, bypass passages and discharge transitions. Confirm zones by feed direction, drop height, lump size, liner holes and downstream chute structure.
View the common part page →Drive and support components are distinct from wear parts. Confirm eccentric shafts, bearings, bushes, hydraulic adjustment, pulleys and flywheels against interfaces and loads.
Eccentric Shaft Assembly
The eccentric shaft produces constant-stroke roll oscillation and is a primary load-bearing drive part. Confirm shaft diameter, eccentricity, fits, bearing seats and end connections together.
View the common part page →Roll Bearing & Bushing
These support the eccentric shaft and rotating roll under high radial load, impact and slow oscillation. Confirm type, clearance, bush dimensions, lubrication and seals from installation records.
View the common part page →Hydraulic Gap Setting & Retraction
The system adjusts the jaw gap, compensates liner wear and retracts for uncrushable material. Confirm bore, stroke, trunnions, seals and pressure rating for the model.
View the common part page →Pulley, Flywheel & V-Belt Drive
The OEM design uses a motor, V-belts and a high-inertia flywheel. Confirm diameters, grooves, taper bushes, bores, keyways, balance grade and guards from installed interfaces.
View the common part page →Jaw Support & Connection Parts
These connect the jaw, hydraulics and frame, affecting discharge setting and retraction. Check pins, lugs, bushes, fasteners and handedness together.
View the common part page →No. Confirm serial number, liner segments, fixings, jaw configuration, wear-compensation position, drawing and revision.
ERC originated in thyssenkrupp Mining Technologies, which joined FLS in 2022. Both legacy installation identity and current business succession must be retained.
Identification can start from the full model, serial number, installed drawings, worn-part photos, measurements and material/duty details. Traceable drawings and technical approval are required before manufacture.
Provide model, serial number, CSS, liner segmentation, drawing, photos, dimensions, materials and duty. We coordinate identification, material assessment, manufacture, quality control and delivery.

ANRANST provides customers worldwide with engineering assessment, production at certified foundries to the customer technical requirements, quality control and finished-part delivery for custom wear parts and industrial spares, with scope to support other custom industrial parts.
We review mating surfaces and interface dimensions and assess material, heat treatment and manufacturing feasibility.
Material grades and heat-treatment processes are specified order by order, stated in the technical agreement and tracked through production.
Drawing confirmation, material and process control, production tracking, inspection and acceptance coordination.
We coordinate manufacturing, quality confirmation, packaging and delivery of complete finished parts in a workable, closed-loop supply process.
Provide the existing model, drawings, drawing, materials or operating conditions so we can identify the appropriate technical review and supply route.
