Identify QMR², QMK², QMC² and QMS² installations, then check grinding rollers, tables, nozzle rings, bearings, hydraulics and drives for wear parts and spares.
quadropol® uses modular roller units configured for material and project. Only manufacturer-published families and installed models are listed; model codes are not interpreted as dimensions without evidence. Manufacture requires nameplate, serial number, installation drawings and actual interfaces.
Models come from current Polysius product pages, project references and QMR² / QMC² / QMK² brochures. No unpublished complete model table is inferred.

Before manufacture, confirm full model, nameplate, serial number, roller count, table/roller dimensions, TD / RD drive, separator, drawing number and revision.
Pressure, impact, abrasion, airflow erosion and heat differ by position. Confirm material, working layer and manufacture separately.
أسطوانة الطحن Tyre
Core quadropol® wear parts that compact and grind the bed. Confirm profile, working surface, bore, keys/clamps, roller position and wear allowance against installation drawings.
Material selection: Raw meal, clinker, slag and coal differ in abrasion and impact. Assess wear-resistant iron, alloy steel or composite hardfacing, controlling core toughness, working layer and cracks separately.

Grinding Table Liner / Segment
Form the rotating table surface and grinding bed with the rollers. Check segment count, curves, thickness, holes, inner/outer positions, dam-ring interfaces and wear templates as a set.
Material selection: Select wear-resistant castings, alloy steel or hardfaced composites for contact pressure, abrasion and thermal cycles. Joints, fastenings and remaining thickness are key acceptance points.
View the common part page →
Nozzle Ring / Louver Ring
Regulate upward air around the table to carry material. Confirm blade angles, flow area, sections, diameters, fastening and table clearance against housing and process configuration.
Material selection: Face high-speed dusty air, abrasion and local heat. Assess wear plate, alloy steel or local composite reinforcement, focusing on blade edges and fastenings.
View the common part page →
Dam Ring / Retention Ring
Control bed depth at the table edge and stabilize grinding. Match height, segments, diameters, interfaces, table position and adjustment to the specific QMR², QMC², QMK² or QMS² installation.
Material selection: Edges face sliding wear, compression and impact. Balance wear resistance, toughness and serviceability; dimensional changes affect the bed, so appearance alone is insufficient.

بطانة مزلق التغذية
Protect central feed/drop passages from lump impact, sliding wear and buildup. Check profile, holes, drop height, slope and position relative to table centre against chute drawings.
Material selection: Select wear plate, elastomers or composite liners for feed size, moisture, drop and adhesion; check blockage, delamination and fastener wear.
View the common part page →
Mill بطانة المبيت
Protect chamber casing, access doors and dusty-air erosion areas. Check zones, curves, holes, welded/bolted attachment, openings and airflow against casing layouts.
Material selection: Low-impact erosion zones may use wear plate or composites; high-impact areas require tougher bases. Control thickness, overlaps, distortion and welding heat effects.
View the common part page →
Reject Chute Liner
Protect passages for coarse particles not entrained by air, tramp metal and rejects. Check drop points, bends, doors, joints, holes and downstream interfaces against return-system drawings.
Material selection: Select impact and sliding-zone materials separately from wear plate, tough alloy steel or elastic composites, retaining maintenance and clearing space.
View the common part page →Check drive and functional spares by family, interfaces, loads, speed, material, heat treatment, flaw detection, seals, lubrication and dynamic balance.
Pre-Assembled Roller Unit
Includes roll, shaft, pivot support, rolling bearings, cylinder, lubricator and interfaces. Count and design vary by family/project; identify the complete assembly from drawings.
Material selection: Manufacture and accept shafts, supports, housings and connectors together against heavy-load fatigue, contact stress, flaw detection, heat treatment and fits.
Submit roller-unit assembly drawings →
Roller Bearing & Seal
Support the roller and exclude chamber dust. Confirm bearing designation, clearance, journal, housing bore, covers, lubrication, seal design and orientation against nameplate and installation records.
Material selection: Match bearings to original designation, load and clearance; select seals for dust, temperature, lubricant, journal condition and speed, not appearance alone.
View the common part page →
Hydraulic Cylinder, Accumulator & Seal Set
Each cylinder applies grinding force to its roller unit, with accumulators cushioning loads. Check bore, stroke, pins, mounting distance, pressure, interfaces and seals as a set.
Material selection: Select cylinder, rod and pin materials/surfaces for high-pressure fatigue and side loads; confirm seals for pressure, temperature, speed and oil, with pressure testing.
View the common part page →Table Drive علبة التروس & Coupling
For QMR², QMK², QMC²-TD and other table-drive configurations. Check motor, gearbox, coupling, output flange, thrust support, rotation, power and speed against nameplates and interface drawings.
Material selection: Confirm gears, shafts, couplings and supports against torque, contact fatigue, impact, tooth heat treatment, flaw detection, accuracy and lubrication.
Submit drive nameplates and interface drawings →QMC²-RD Roller Drive Unit
Each QMC²-RD roller has an independent motor and gearbox. Confirm drive count, roller speed, couplings, torque supports, rapid-decoupling interfaces and guards for the specific cementitious-material mill.
Material selection: Match gears, shafts and connectors to speed, torque, redundant operation, fatigue, heat treatment, balance and oil. They cannot be mixed with table-drive parts.
Submit QMC²-RD drive records →
Separator Rotor & Guide Vane
Control product fineness under high-speed dusty airflow. Confirm rotor diameter, vane count/angle, shafts, liners, balance grade, speed and mill-casing interfaces against separator drawings.
Material selection: Vanes and erosion areas require low weight, stiffness, wear resistance and weldability; control rotor/shaft dimensions, weld quality and dynamic balance.
View the common part page →Only the extraction/transfer arrangement explicitly shown on the current manufacturer page is presented. Loads and interfaces require design checks for the specific mill and building.
Roller Unit Extraction & Transfer Arrangement
The manufacturer shows a project arrangement for extracting and transferring a roller unit through the maintenance opening. Recheck rails, loads, travel, opening, lifting points and space for the specific mill and building.
Material selection: Project-specific maintenance arrangement, with no universal interchangeability claim. Design and accept structures, welds, pins, wheelsets and stops against roller-unit mass and site safety requirements.
Submit mill and building drawings for maintenance-layout assessment →No. Feed, roller count, rollers/tables, airflow, classification, drives and safety differ. Even similar model numbers require full model, serial number and drawing checks.
The manufacturer uses them as model identifiers, but a uniform public definition covering every generation has not been established here. No conversion is assumed; nameplates, drawings and measurements establish dimensions.
No. Dimensions, position, fastening, material or sample chemistry, hardness, wear conditions, roller unit and drawing revision are needed; use three-dimensional measurement and material testing where necessary.
Provide full model, serial number, roller count, TD / RD drive, drawing number, old-part photos, material, dimensions and conditions for identification, material assessment, manufacture, quality control and delivery.
