Start with five standard models and key dimensions to identify jaw liners, roll surfaces, grates, hood wear protection, eccentric roll shafts, bearings and hydraulic spares, then confirm materials and drawing for an enquiry.
ERC combines an eccentric single-roll crusher with a static grate. This page covers the standard models, dimensions, installation positions, material selection, drawing checks and enquiry information directly needed for spare identification.
Models, capacity, feed opening, roll diameter and width, CSS, drive power, equipment weight and overall dimensions come from the corresponding official FLS datasheets.
| Model | Capacity | Feed opening | Roll diameter / width | CSS range | Drive power | Equipment weight | Overall dimensions L×W×H |

| ERC 25-25 | 1,450–4,900 t/h | 2,500 × 1,300 mm | 2,500 / 2,500 mm | 100–260 mm | 450–600 kW | Approximately 185,000 kg | Approximately 7,100 × 4,700 × 4,300 mm |
| ERC 25-30 | 2,150–7,300 t/h | 3,000 × 1,300 mm | 2,500 / 3,000 mm | 100–300 mm | 500–700 kW | Approximately 215,000 kg | Approximately 7,100 × 5,200 × 4,300 mm |
| ERC 25-34 | 2,600–8,800 t/h | 3,400 × 1,300 mm | 2,500 / 3,400 mm | 100–300 mm | 600–800 kW | Approximately 240,000 kg | Approximately 7,100 × 5,600 × 4,300 mm |
The numbers on the diagram correspond one to one with the rows below.
| No. | Component | Location | Applies to |
|---|---|---|---|
| 1 | Integrated static grizzly | Upper feed-side screening section | ERC22-20 |
| 2 | Housing | Machine housing | ERC22-20 |
| 3 | Roll | Eccentric roll inside the chamber | ERC22-20 |
| 4 | Jaw | Crushing surface opposite the roll | ERC22-20 |
| 5 | Hydraulic gap setting system | Adjustment assembly beside the crushing chamber | ERC22-20 |
| 6 | Hood | Top of the housing | ERC22-20 |
Parts are ordered by actual installation position: jaw liners and roll surfaces in the chamber first, followed by static grates, side guards, hoods and discharge areas. Each item links to its part and material pages.
Crushing Jaw Liner
Attached to the swing jaw, these form the fixed wear face on the jaw side of the ERC chamber. Check model, liner segments, tooth profile, thickness, hole pattern, assembly direction, CSS range and used-part wear profile.
View Part Details →Roll Liner / Roll Surface
These fit around the eccentric roll and form the principal wear surface working against the jaw liners. Check roll diameter and width, segment count, circumferential location, fastenings, surface profile and rotation direction.

Roll Shell Segment
For segmented roll surfaces, identify each segment by circumferential position and assembly sequence. Check arc length, width, interfaces, fastening holes, locating structure and adjacent segment overlaps.
View Part Details →Integrated Static Grizzly Wear Parts
The integrated static grate on the feed side allows fines to bypass the crushing chamber. Check grate length, openings, bar cross-section, spacing, support positions, wear direction and replacement access.

Side Liner / Cheek Plate
These protect chamber sidewalls and areas near the roll ends. Check left/right side, plate shape, thickness, hole pattern, jaw and roll clearances, discharge passages and wear zones.
View Part Details →Hood Liner
FLS datasheets identify the lined hood as one of the largest components handled during routine maintenance. Check machine model, hood profile, liner segmentation, lifting points, fastening holes and maintenance opening direction.

Discharge Chute Liner
Located below the chamber, these face high-velocity material flow and localized impact. Check discharge direction, plate thickness, segment numbers, hole patterns, overlaps and blockage clearance.
View Part Details →These three core spare categories link to their general part pages. Parts with the same name are not interchangeable by appearance across ERC models. Check structure, dimensions, loads, fits, materials and drawing.
Eccentric Roll Shaft and Roll Assembly
FLS datasheets identify the roll assembly with bearings and liners as the largest transport unit. Check eccentricity, journals, roll diameter and width, bearing housing spacing, keys/locking assemblies, rotation direction and dynamic balance.
View Part Details →
Bearings, Bushings and Housings
Bearings support the eccentric roll under cyclic crushing loads. Check bearing model, clearance, journals, housing bores, locating/floating end, seals, lubrication and temperature monitoring interfaces.
View Part Details →Hydraulic Gap Setting and Tramp Release System
These adjust CSS, compensate for liner wear and release uncrushable objects. Check cylinder bore, stroke, working pressure, mounting trunnions, valve blocks, accumulators, ports and seal grooves.
