Start with the PM model, roll diameter and width to identify roll wear systems, load-bearing and hydraulic spares, materials and drawing references for quotation.
The official FLS HPGR brochure lists roll diameter, width, grinding force, dual-motor power and overall dimensions for PM0, PM1 and PM3 to PM10. HPGR Pro features apply to new machines or confirmed Standard upgrade projects.
Dimensions are from the official FLS HPGR / HPGR Pro Upgrades brochure. For roll surfaces, bearings, hydraulics and drive spares, also verify serial number, fixed/floating roll position and upgrade configuration.

HPGR Pro features include rotating side plates, mechanical skew limiters, stud detection, oil-lubricated main bearings and the AMPS machine-protection system. Verify applicability by machine size and project modification documents.
The roll centre, edges, side plates and feed/discharge passages have different wear mechanisms. The cards link part location and material choices to component pages; final confirmation follows the PM model and drawings.
Roll Surface / Roller Tyre
The main working surface of the high-pressure material bed. Check diameter, width, surface design, edges, wear profile and connection to the roll shaft.
Material assessment: Verify roll substrate, hardfacing and carbide wear system against the original design and ore abrasiveness.
View the Component Page →
Tungsten Carbide Stud
Embedded studs retain an autogenous protective material bed. Match diameter, length, head shape, spacing density, sockets and edge transitions.
Material assessment: Confirm carbide grade, cobalt content, toughness and abrasion resistance for the ore and original design.
View the Component Page →
Edge Block / Edge Protection
Protect roll edges and control edge wear. Check inner/outer side, circumferential position, mounting grooves, fastening and transition to the studded area.
Material assessment: Assess carbide composites, high-chromium wear alloys or hardfacing against the original construction.
View the Component Page →
Cheek Plate / Rotating Side-Plate
Contain material at the roll-gap sides under high-pressure abrasion. For HPGR Pro rotating plates, also check the rotating mechanism, clearance and seals.
Material assessment: Select high-chromium materials, bimetallic composites or quenched-and-tempered wear plate by side-plate design and wear zones.
View the Component Page →
بطانة مزلق التغذية
Withstand coarse-particle impact and stabilize feed to the roll gap. Check position, drop angle, thickness, hole pattern and side-plate interfaces.
Material assessment: Use quenched-and-tempered wear plate, bimetallic composites or high-chromium materials by impact and wear intensity.
View the Component Page →
بطانة قناة التفريغ
Withstand compacted-cake drops, impact and sliding wear. Check drop height, impact point, liner joints, fixing and service access.
Material assessment: Select quenched-and-tempered plate, bimetal or ceramic–rubber composites separately for impact and sliding zones.
View the Component Page →
الكاشطة / المنظف
Remove adhered material from rolls or passages. Check scraper profile, preload, clearance, movement direction and bracket interfaces.
Material assessment: Assess wear-resistant polyurethane, rubber or hardfaced steel scrapers for adhesion and wear conditions.
View the Component Page →
Press Frame / Hopper Liner
Protect frame and hopper areas exposed to impact, compression and sliding wear. Check plate shape, thickness, overlap direction and mounting.
Material assessment: Quenched-and-tempered wear plate, bimetallic composites or polymer liners confirmed for the duty.
View the Component Page →Distinguish HPGR Standard / Pro, PM model, machine side, fixed/floating roll and upgrade status. Only confirmed reference matches are published on component pages.
Main Bearing & Bearing Seal
Check PM and bearing models, fixed/floating end, clearance, lubrication, seal design and temperature-monitoring connections.
Material assessment: Bearing steel and seal systems such as NBR, HNBR and FKM; confirm grades against the original part and fluid.
View the Component Page →
Hydraulic Cylinder & Seal Set
Load the roll gap and move the floating roll. Check bore, rod diameter, stroke, pressure, mounting trunnions, seal grooves and fluid.
Material assessment: Polyurethane primary seals with NBR, HNBR or FKM secondary seals, verified for pressure, temperature and fluid.
View the Component Page →Roll Shaft & Roll Assembly
Include fixed and floating rolls, shafts and connections. Check journals, bearing seats, roll interfaces, concentricity, heat treatment and nondestructive testing.
Material assessment: Large specialist alloy-steel forgings; confirm material and heat treatment by original drawings, loads and inspection specifications.

علبة التروس, Coupling & Drive Shaft
Identify each side of the dual-motor system as an assembly. Check power, ratio, output shaft, coupling, torque limitation and mounting datums.
Material assessment: Transmission alloy steel and matching bearing materials; confirm gear and shaft heat treatment against the original design.
View the Component Page →Oil Lubrication & Filtration Components
For HPGR Pro oil-lubricated main bearings, check pumps, filters, coolers, valves, pipe connections, oil and monitoring elements.
Material assessment: Select seal and hose materials by oil, temperature and pressure; verify metal housings and connections against system drawings.
Send Drawings and References →Mechanical Skew Limiter Assembly
An HPGR Pro assembly that limits floating-roll skew. Check machine size, mounting side, locking design, links and sensor connections.
Material assessment: Load-bearing structures and pins require the drawing-specified alloy steel and surface treatment; generic shape alone cannot establish a replacement.
Send Drawings and References →Submit the PM model, Standard / Pro version, fixed/floating roll, machine side, roll diameter and width, drawing revision and used-part photographs with any reference to prevent number-only mismatches.
First check PM model and machine size, then roll diameter, width, serial number, surface type, fixed/floating roll position and Standard / Pro configuration.
FLS states that machine sizes 4–10 can receive Pro upgrades. Each modification and part still requires checks against size, serial number, upgrade scope and modification drawings.
Yes. Submit the reference, PM model, roll diameter and width, location, surface layout, used-part photographs and material data to establish a match.
Provide PM model, Standard / Pro, serial number, fixed/floating roll and side, surface layout, OEM/third-party reference, drawings, material and duty. These support identification, material assessment, production at certified foundries, quality control and delivery.
