Start with GM140-60, GM240-170 and roll diameter × width, then identify the roll surface, studs, edge protection, cheek plates, bearings, hydraulics, materials and inquiry requirements.
This page uses GM140-60 and GM240-170 to organize model identification and spare-part paths. Confirm other installed models from the complete nameplate and project documentation.
The numbers in a GM model identify nominal roll diameter and width. Confirm the actual power, pressure, capacity, roll-surface configuration and bearing system from project documentation.
| Model | Nominal Roll Diameter | Nominal Roll Width | Required Checks Before Manufacturing |
|---|---|---|---|
| GM140-60 | 1,400 mm | 600 mm | Project nameplate, roll-surface type, bearings, hydraulics and drawing revision |
| GM240-170 | 2,400 mm | 1,700 mm | Project nameplate, roll-surface type, bearings, hydraulics and drawing revision |
Nominal model dimensions do not replace manufacturing dimensions for the roll surface, studs or structural parts. Confirm roll-surface type, hole pattern, edge protection and fits from the original drawings.
Roll surfaces and studs are presented first. Different positions are exposed to high contact stress, abrasive wear, edge wear or feed impact, so materials and manufacturing processes are confirmed separately.
Roll Surface / Roller Tyre
Directly grips and compresses the material bed and is the HPGR's principal wear zone. Confirm roll diameter, roll width, surface construction, base material, assembly method and wear zones.
Material Selection: Forged alloy-steel base with studs, hardfacing or composite wear construction. Confirm material and process according to ore, pressure, particle size and maintenance method.

Roller Stud
Embedded in the roll surface to form an autogenous wear-protection layer while resisting high contact stress and abrasive wear. Confirm diameter, length, head shape, layout, hole diameter and fit.
Material Selection: Confirm the cemented-carbide system and its fit with the base according to impact, ore abrasiveness, stud-breakage records and press-fitting process.

Edge Protection / Edge Liner
Protects roll-surface edges and controls edge wear. Confirm left/right orientation, segmentation, profile, fastening arrangement, roll-surface interface and wear height.
Material Selection: Confirm cemented carbide, wear-resistant alloy steel or composite construction according to edge pressure, impact and replacement method.

Cheek Plate / Side Liner
Located on both sides of the roll gap to limit lateral material escape while resisting severe wear. Confirm clearance, profile, left/right orientation, support construction and adjustment range.
Material Selection: Confirm quenched-and-tempered wear plate, composite wear plate or ceramic-composite construction according to abrasive wear, impact and clearance stability.

Feed Chute Liner
Protects the feed chute against material impact and sliding wear. Confirm segmentation, thickness, overlap, hole pattern, drop height and flow direction.
Material Selection: Confirm quenched-and-tempered wear plate, high-chromium cast iron or composite wear construction according to the ratio of impact to abrasive wear.

Discharge Chute Liner
Protects the product-cake discharge and transfer area. Confirm flow direction, segmentation, thickness, curved surfaces, hole pattern, supports and adjacent-equipment interfaces.
Material Selection: Confirm quenched-and-tempered wear plate, high-chromium cast iron, ceramic or composite wear construction according to particle size, velocity and impact.

Press Frame Liner
Protects the press frame and adjacent feed-receiving area. Confirm installation zone, thickness, hole pattern, welded or bolted attachment and maintenance access.
Material Selection: Confirm quenched-and-tempered wear plate or composite wear plate according to impact, abrasive wear, weldability and replacement method.
View Part Details →Check support and hydraulic parts separately against the complete model, load, interfaces, fits, tolerances, lubrication, pressure, material and seal combination.
Bearing & Bearing Seal
Supports the roll assembly and isolates dust and lubricant. Confirm the complete bearing designation, clearance, journal, housing bore, tolerances, seal combination and lubrication system.
Material Selection: Use bearings and seals to the original specification. Confirm bearing housings and shaft parts according to load, temperature rise, fits and inspection requirements.

Hydraulic Cylinder Seal
Maintains pressure in the roll-loading system and excludes contaminants. Confirm cylinder bore, rod diameter, groove, operating pressure, temperature, fluid and seal-stack orientation.
Material Selection: Confirm polyurethane, NBR, HNBR, FKM, PTFE or composite seals according to pressure, temperature, speed and hydraulic fluid.
View Part Details →
Scraper / Cleaner
Removes adhering material from the roll surface or adjacent area. Confirm position, direction, blade profile, clearance, bracket, preload and roll-surface construction.
Material Selection: Confirm quenched-and-tempered wear steel, polyurethane or composite scraper blades according to material adhesion, wear, temperature and roll-surface protection requirements.
View Part Details →GM part numbers must be confirmed against the complete model, installation position and drawing revision. Numbers are not inferred on this page.
Selection Guidelines: Part numbers must match the model, installation position and installed-equipment drawings. OEM drawing numbers and third-party part numbers are checked separately.
No. They identify the machine's nominal roll diameter and width; they are not manufacturing dimensions for the roll tire, studs, edge blocks or cheek plates.
No. Also confirm geometry, hole pattern, fit, base material, press-fitting process, ore, pressure, stud-breakage mode and roll-surface maintenance strategy.
Submit the nameplate, roll diameter and width, equipment general arrangement, installation position, used-part photographs, roll-surface wear records and key dimensions to assess identification, reverse engineering and manufacturing requirements.
Provide the complete model, roll diameter, roll width, serial number, drawings, used-part photographs, materials and operating conditions. We will use them for part identification, material assessment, manufacturing matching, quality control and finished-part delivery.
