Start with standard RollSizer 500–1500 sizes and roll lengths to identify crushing teeth, tooth rings, side combs, breaker bars, liners, roll shafts, bearings, gears and drives, then confirm materials.
CenterSizer crushes between the two rolls; SideSizer crushes between the toothed rolls and side combs. The same machine size may have different roll lengths and drive arrangements. Confirm spares against the full DRS model, serial number, toothed roll layout and drawings.
Values come from the official FLS RollSizers brochure. Feed size, capacity, power and weight are example or guidance values for medium-hard limestone. Actual project values vary with tooth profile, material, particle size, density, roll length and product size.

| RollSizer 800 | 1,500 / 2,000 / 3,000 mm | Approximately 920 mm | 750–1,050 mm | Up to approximately 3,500 t/h | 200–630 kW | Approximately 27 / 32 / 40 t |
| RollSizer 1,000 | 2,000 / 3,000 mm | Approximately 1,020 mm | 950–1,300 mm | Up to approximately 5,000 t/h | 250–700 kW | Approximately 42 / 51 t |
| RollSizer 1,250 | 2,000 / 3,000 mm | Approximately 1,450 mm | 1,200–1,600 mm | Up to approximately 7,500 t/h | 450–800 kW | Approximately 81 / 100 t |
| RollSizer 1,500 | 3,000 / 4,000 mm | Approximately 1,800 mm | 1,400–2,000 mm | Up to approximately 10,000 t/h | 750–1,200 kW | Approximately 125 / 150 t |
The numbers on the diagram correspond one to one with the rows below.
| No. | Component | Location | Applies to |
|---|---|---|---|
| 1 | Crushing teeth | Toothed working surfaces of both rolls | CenterSizer |
| 1 | Toothed segments | Around the crushing roll | SideSizer operating design; no size-specific assembly |
| 2 | Crushing rolls | Two rolls in the crushing chamber | CenterSizer |
| 2 | Lateral crushing comb | Stationary comb beside the roll | SideSizer operating design; no size-specific assembly |
| 3 | Breaker bar | Below and between the rolls | CenterSizer |
| 3 | Crushing roll | Circular roll body | SideSizer operating design; no size-specific assembly |
Follow the material as it enters the chamber, is gripped by the toothed rolls, crushed in the centre or at the sides, and discharged. Each item links to its part and material pages.
Replaceable Crushing Tooth / Tooth Pick
Teeth fit on roll tooth rings or shaft slots to grip and shear material. Check CenterSizer / SideSizer configuration, roll diameter, tooth position and profile, installation angle, holder, fastening structure, rotation direction and target product size.
View Part Details →Tooth Ring / Tooth Segment and Roll Shell
The complete tooth ring or segment set forms the roll's working profile. Check roll diameter and length, segment count, tooth layout, shaft bore/splines, flanges, spacers, keys, fastenings and assembly sequence.
View Part Details →Side Crushing Comb / Side Liner
SideSizer crushes between its toothed rolls and adjustable side combs, which also determine product size. Check left/right side, comb tooth profile, clearance, adjustment range, hole pattern, supports and discharge direction.
View Part Details →Breaker Bar / Anvil
Some primary CenterSizer configurations use a breaker bar below the rolls for secondary breakage of large lumps. Check roll spacing, bar profile, tooth surfaces, installation height, supports, replaceable wear blocks and discharge clearance.

Housing Liners, End Plates and Scrapers
These protect chamber sidewalls, ends and accumulation areas below the rolls while maintaining roll clearances. Check zone numbers, left/right orientation, curvature, plate thickness, hole patterns, overlaps, scraper clearance and wear location.
View Part Details →Confirm high-torque, low-speed drive parts against single/dual drive arrangement, shaft spacing, roll length, rotation direction and complete drawings. Machine appearance or size alone does not establish interchangeability.
Crushing Roll Shaft
Roll shafts carry tooth rings and transmit high torque. Check overall shaft length, shaft spacing, bearing seats, ring/spline/key interfaces, flanges, drive end, rotation direction, concentricity, non-destructive testing and repair history.
View Part Details →Bearing and Bearing Housing
Bearings support both rolls and maintain shaft spacing and tooth clearances. Check bearing designation, clearance, shaft/housing fits, end covers, seals, lubrication, temperature monitoring, locating arrangement and left/right side.

Synchronisation Stage, Gears and Gearbox
Single-drive configurations coordinate both rolls through a timing stage; dual-drive configurations drive each shaft separately. Check drive type, ratio, tooth count, module, helix direction, mounting distance, bores, couplings, lubrication and tooth contact.
View Part Details →Fluid Coupling and Drive Connection
These connect motors, reducers and rolls while absorbing start-up or overload shocks. Check power, speed, bores, keys, coupling dimensions, fluid filling, guards, brakes and electric/hydraulic drive configuration.
View Part Details →Tooth Fasteners, Spacers and Shims
These locate crushing teeth, rings and side combs and set roll-system clearances. Check position numbers, threads, grade, length, head type, locking method, spacer thickness, shim stack and site assembly sequence.
View Part Details →FLS specifies materials by application, not one universal grade. First screen material families against feed hardness, abrasiveness, moisture and stickiness, maximum lump size, tooth profile, impact and used-part failure. Complete confirmation using drawings, material testing, heat treatment and acceptance requirements.
Machine size alone is insufficient. Crushing position, side combs, tooth profiles and discharge clearances differ. Check the complete structure, roll length, tooth position, drive, serial number and drawings.
The official table lists several standard roll lengths for a single machine size. Weight, tooth segment count, shaft system and housing change accordingly. Machine size is only the first level of installation identification.
Provide the full model, serial number, CenterSizer/SideSizer type, roll length, toothed roll layout, tooth positions, drawings or samples, used parts, material and feed conditions. We use these to identify parts, assess materials, match manufacturing requirements, control quality and deliver finished components.
