The current Polysius high-pressure bed-grinding range: identify wear, bearing, hydraulic and drive parts by project configuration, roll design, diameter/width and installation position.
polycom® is customized for material, output and process rather than sold through uniform public model codes. Published configurations, historical installation size ranges and roll, bearing, hydraulic and drive data support spare identification against actual machine records.
The current website describes project-specific polycom® configurations without uniform model codes. The table lists only traceable current configurations and historical mineral-HPGR dimensions.
| Published configuration / installation range | Roll diameter / identification range | Roll width / configuration | Capacity and application | Product status |
|---|---|---|---|---|
| polycom® raw-material finish grinding | Customized by material and output | Project-specific | Published maximum capacity exceeds 2000 t/h; maximum feed size 60 mm | Current product |
| polycom® cementitious-material finish grinding | Customized for cement clinker, slag and other materials | Project-specific | Paired with sepol® classification | Current product |
| polycom® pregrinding / combined grinding | Adapted to the existing ball mill circuit | Project-specific | Capacity-expansion and energy-saving retrofits | Current product |
| Polysius mineral HPGR installed range | Roll diameter 0.5–2.8 m | Roll width 0.2–1.8 m | 20 to over 2500 t/h; 2 × 50 to 2 × 3000 kW | Historical technical-data range |

Roll surfaces, studs, edges, cheek plates and chutes face different pressure, impact and wear mechanisms. Confirm materials and processes separately by position.
Forged / Welded Roll Body
Hardfaced profiles retain a material bed for autogenous wear protection. Confirm diameter, width, hardfacing type, pattern, hard layer and edge design against installation drawings.
View the common part page →Compound-Cast Roll Body
A tough core and high-compressive-strength outer layer serve high-specific-wear duties. Confirm layer thickness, interface, profile, ends and shaft assembly as a complete roll unit.
View the common part page →
Hard-Metal Studded Roll Surface
Studs retain a protective material bed. Diameter, length, density, pattern, edge zones and hole fits vary with roll and feed.
View the common part page →
Cheek Plate / Side Liner
Limit lateral escape from the roll gap and stabilize the feed column. Check profile, thickness, clearance, supports, left/right position and edge wear zones by roll diameter and width.
View the common part page →
Roll Edge Protection
Protect high-wear roll ends against spalling and side leakage. Confirm segments, fastening, end faces, overlaps with stud zones and left/right roll position against original drawings.
View the common part page →
Feed Chute Liner
Cover feed drop points and the material column, supporting uniform feeding and protecting the chute shell. Confirm holes, joints, drop height, access and cheek-plate interfaces against chute drawings.
View the common part page →
Discharge Chute Liner
Protect cake-discharge and transfer passages against sliding wear, local impact and buildup. Confirm profile, holes, joints, slope and downstream interfaces against discharge-chute drawings.
View the common part page →Check drive and functional parts individually for interfaces, loads, materials, heat treatment, flaw detection, machining, sealing and system parameters.
Fixed Roll Unit
Roll body, mainshaft, bearings, seals and end interfaces are fixed on one frame side. Confirm diameter, width, journals, supports, drive end and surface design as an assembly.
Submit fixed-roll assembly drawings →Floating Roll Unit
Moves along guides under hydraulic cylinders to generate grinding force. Besides rolls and bearings, check sliding guides, pressure beams, cylinder mounts, stops and skew-control interfaces together.
Submit floating-roll assembly drawings →
Roll Bearing & Seal
Carry high grinding forces, impact and skew loads. Confirm bearing designation, clearance, housing bore, covers, labyrinths, oil seals, lubrication and left/right position against installation records.
View the common part page →
Hydraulic Cylinder & Seal Set
Apply preload and grinding force to the floating roll, working with accumulators to absorb load fluctuations. Check bore, stroke, mounting distance, pins, pressure and interfaces as a set.
View the common part page →Drive Gearbox, Coupling & Torque Support
Rolls are usually driven separately. Confirm motors, gearboxes, couplings, hollow-shaft or shaft-end connections, torque supports and guards together by power, speed, rotation and interfaces.
Submit drive nameplates and interface drawings →
Lubrication, Cooling & Scraper System
Includes bearing lubrication, cooling lines, filtration, monitoring and roll/discharge cleaning parts. Check pumps, valves, filters, nozzles, scrapers and instruments against medium and schematics.
View the common part page →Current manufacturer pages explicitly configure machines for material, process and project requirements without a uniform public model table. Identification requires nameplate, roll diameter/width, surface design, serial number and drawings.
No. Roll construction, pressure, specific wear, edge protection, maintenance and project configuration differ. Assess the complete roll unit and operating conditions.
No. Confirm fixed/floating position, journals and housing bores, bearing designation, clearance, cylinder dimensions and pressure, seals, interfaces and drawing revision.
Provide serial number, roll diameter/width, surface design, fixed/floating position, bearing and hydraulic nameplates, drawing, used-part photos, material and conditions for 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 equipment brand, complete model and serial number, part name, part number or drawing number, drawing revision, quantity, material requirements and duty. If identifiers are unavailable, send photographs and key dimensions.
