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 |
The numbers on the diagram correspond one to one with the rows below.
| No. | Component | Location | Applies to |
|---|---|---|---|
| 1 | Feed hopper | Grey feed hopper above the roll frame | GM HPGR product family |
| 2 | Roll frame | Green roll frame on the left | GM HPGR product family |
| 3 | Gear reducer | Green gear reducer between roll frame and motor | GM HPGR product family |
| 4 | Drive motor | Large drive motor at the right | GM HPGR product family |
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.
View Part Details →
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.
View Part Details →
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.
View Part Details →
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.
View Part Details →
Feed Chute Liner
Protects the feed chute against material impact and sliding wear. Confirm segmentation, thickness, overlap, hole pattern, drop height and flow direction.
View Part Details →
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.
View Part Details →
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.
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.
View Part Details →
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.
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.
View Part Details →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.
