Identify legacy models, principal dimensions, wear parts and drive spares. The former Mining Technologies business became part of FLS in 2022.
RollSizer applies shear and tension at low speed and high torque. CenterSizer crushes between the rolls; SideSizer crushes between roll teeth and side combs. This page identifies legacy wear parts and spares; project configurations do not establish universal interchangeability.
The table follows the historical thyssenkrupp RollSizers brochure and DRS 1000 × 3000 C data sheet. Capacity, power, feed and weight depend on material, tooth profile, Center/Side arrangement and project configuration.

| DRS 500 | 500 mm / 1000–2000 mm | Approx. 480–650 mm (SideSizer approx. 200 mm) | Up to approx. 1500 t/h / 55–220 kW |
| DRS 660 | 660 mm / 1500–3000 mm | Approx. 650–850 mm (SideSizer approx. 300 mm) | Up to approx. 2500 t/h / 160–500 kW |
| DRS 800 | 800 mm / 1500–3000 mm | Approx. 750–1050 mm | Up to approx. 3500 t/h / 200–630 kW |
| DRS 1000 | 1000 mm / 2000–3000 mm | Approx. 950–1300 mm | Up to approx. 5000 t/h / 250–700 kW |
| DRS 1250 | 1250 mm / 2000–3000 mm | Approx. 1200–1600 mm | Up to approx. 7500 t/h / 450–800 kW |
| DRS 1500 | 1500 mm / 3000–4000 mm | Approx. 1400–2000 mm | Up to approx. 10000 t/h / 750–1200 kW |
| DRS 1000 × 3000 C (B) | 1000 mm / 3000 mm | Feed opening 3000 × 2280 mm; machine 6600 × 3740 × 1625 mm | Coal/lignite; up to approx. 3000 t/h; 2 × 200 or 2 × 250 kW |
Series numbers and roll length support preliminary identification. Before manufacture confirm the full model suffix, serial number, tooth profile and rows, breaker-bar option, drive arrangement and drawing revision.
Identify tooth segments, rings, breaker bars, side combs, liners and fasteners separately. Each card links to the corresponding component and material pages.
Replaceable Tooth Pick / Tooth Segment
Teeth surround both rolls; profile, row count, axial position and roll spacing determine gripping and discharge. Confirm CenterSizer/SideSizer, full model, tooth sequence and installed drawings.
Material selection: OEM literature specifies wear-resistant steel selected for the duty. Confirm grade, hardness and reinforcement from drawings and actual impact and abrasion conditions.

Replaceable Tooth Ring
CenterSizer may use complete tooth rings or individual replaceable blocks. Check diameter, axial width, interfaces, rotation direction and tooth arrangement together.
Material selection: Assess alloy cast steel and local reinforcement; final material, heat treatment, NDT and life targets follow the original drawing.
View the common part page →Breaker Bar
DRS CenterSizer can have a height-adjustable breaker bar to increase reduction and control product size. Confirm whether it is fitted and its installed height.
Material selection: Select wear-resistant steel or composite reinforcement for the working face's impact, compression and abrasion.
View the common part page →
Side Crushing Comb / Cleaner
SideSizer teeth and adjustable side combs form the discharge gap. Confirm tooth profile, comb position, gaps and fixing holes against the installed arrangement.
Material selection: Comb teeth need impact toughness, edge wear resistance and fixing strength. Similar appearance or hardness alone is insufficient for replacement.
View the common part page →
Side Liner / Wear Protection Plate
Housing and chamber liners protect structures and maintain working clearances. Confirm CenterSizer/SideSizer layout, thickness, holes and edge profile.
Material selection: Select quenched-and-tempered wear plate or cast wear parts for material hardness, impact and sliding wear; verify welding and countersunk-hole requirements.
View the common part page →
Tooth Segment Fastener
Fasteners clamp and locate tooth blocks, rings or mounting bases under cyclic impact and vibration. Confirm thread, head, strength grade, preload and locking together.
Material selection: Specify high-strength alloy steel, heat treatment, mechanical properties and corrosion protection from drawings. Check fasteners with tooth segments as mating interfaces.
View the common part page →Drive components are separate from wear parts. Confirm shafts, bearing housings, gearboxes and synchronizing systems against installed interfaces, loads and drawings.
Crushing Roll Shaft Assembly
Includes the shaft, segment mounting zones, end connections and bearing seats. Confirm spacing, length, tooth profile, shaft position, rotation direction and complete shafting drawings.
Material selection: Confirm shaft material, forging route, heat treatment, NDT, fit tolerances and surface quality against the drawing and torque loads.
View the common part page →
Bearing & Bearing Housing
These carry radial and axial loads from low-speed, high-torque shafts. Check bearing type, clearance, housing bore, labyrinth seals, lubrication passages and mounting side together.
Material selection: Confirm bearing type from installation records; housing casting or weldment, machining accuracy and NDT follow the original drawing.
View the common part page →Heavy-Duty Gearbox
OEM DRS documentation uses custom heavy-duty gearboxes with synchronized single-drive or twin-drive arrangements. Confirm ratio, input/output interfaces, side and lubrication before quotation.
Material selection: Confirm gear and shaft materials, carburizing or quench-and-temper treatment, tooth accuracy and inspection from nameplates, drawings or traceable samples.
View the common part page →Drive Connection & Synchronizing Stage
DRS configurations may use one drive with a synchronizing stage or two independent drives. Identify shafts, couplings, synchronizing gears and guards from the actual layout.
Material selection: Specify materials and heat treatment for torque, impact, fits and fatigue life. Similar appearance cannot replace interface checks.
View the common part page →No. Confirm roll length, C/S arrangement, row count, profile, breaker bar, shaft position, serial number and drawing revision.
Not entirely. CenterSizer mainly crushes between the rolls; SideSizer forms the working gap between teeth and side combs. Check segments, side liners and fixings separately.
This page records thyssenkrupp Mining Technologies installations from before 2022. The business joined FLS in 2022, so both legacy nameplate identity and current succession must be retained.
