Start with CG810i, CG820i, CG830i and CG850i models to identify spider and liner systems, mainshafts, bushings, drive and hydraulic parts, then confirm drawings and request a quotation.
This page covers official specifications, key installation positions, material checks, drawing identification and enquiries relevant to spare-part supply. Model cards use the current short names on the manufacturer's website; the technical table retains CG800i designations.
Weights, feed openings, capacities and power ratings below come from Sandvik's current official CG800i specification table. Confirm the installed machine using its nameplate, serial number, chamber configuration and equipment documents.
| Model | Machine weight | Feed opening | Capacity | Motor power |
|---|---|---|---|---|
| CG810i | 128 t | 1,067 mm | 1,300–2,700 t/h | 315 kW |
| CG820i | 244 t | 1,372 mm | 1,500–4,000 t/h | 525 kW |
| CG830i | 380 t | 1,525 mm | 2,700–6,000 t/h | 660 kW |
| CG850i | 500 t | 1,549 mm | 3,800–8,250 t/h | 950 kW |
Capacity varies with ore properties, feed distribution, chamber, discharge setting and operating conditions. This table supports machine identification and does not replace project sizing or original equipment documents.
Spider protection, concaves, mantles and mainshaft sleeves are shown first. Each card identifies the installation position, service conditions and material checks, with a link to the shared component page.
Spider Cap, Shield & Arm Liner
Above the feed opening, these parts face direct impact from large rocks, uneven loading and sliding wear. Check spider geometry, arm count, plate profile, hole pattern, thickness and feed direction.
Material selection: Confirm manganese steel, quenched-and-tempered wear plate or composite protection against impact energy, thickness and fastening method.

Spider Underside Wear Liner
Protect the spider underside and adjacent areas against rock impact, rebound and abrasive flow. Check left/right orientation, plate layout, holes and contact surfaces against the spider.
Material selection: Choose manganese steel or quenched-and-tempered wear plate according to the balance of impact and sliding wear. For welded structures, also check weldability.
View the common part page →
Top Shell Wear Plate
Protect feed and rebound zones in the upper shell. Check installation zones, thickness, curvature, overlaps, fastening and boundaries with the concaves.
Material selection: Confirm quenched-and-tempered wear plate, manganese steel or composite protection against impact, abrasion and mounting method.
View the common part page →Identify the mainshaft separately from its protective sleeve. Check drive, load-bearing, bearing and hydraulic sealing parts by series, full model, serial number, drawing revision and mating dimensions.
Spider Assembly
The machine image locates the upper spider. For the assembly, check arm structure, central support, connecting flanges, lifting points, bushing seat and machine model.
Material selection: Confirm large cast-steel or welded structures, fasteners and support materials against original drawings, loads and nondestructive examination requirements.
View the common part page →Mainshaft
The machine image indicates the mainshaft centreline; it is not a photograph of the separate shaft. This critical load-bearing component must be checked separately from its external protective sleeve.
Material selection: Confirm forged alloy steel, heat treatment, journal accuracy, straightness and nondestructive examination against the full model, loads and original drawings.

Material selection: Confirm wear-resistant alloy steel and bearing copper alloys against contact pressure, lubrication, flatness and fit requirements.
View the common part page →The locally verified records do not yet provide a publicly traceable CG800i-specific parts list, so no numbers are invented here. With complete information, OEM drawing numbers and third-party part numbers are mapped separately to the model, part name, installation position and key dimensions.
Publication policy: Publish only numbers traceable to a model, installation position and original evidence. Record OEM drawing numbers separately from third-party part numbers; do not mix or infer them.
Sandvik's current product cards use CG810, CG820, CG830 and CG850; official technical tables and brochures use CG810i, CG820i, CG830i and CG850i. Enquiries should use the full nameplate designation and serial number.
No. The mainshaft is a critical load-bearing component; the sleeve is a separate protective part fitted around it. Check drawing numbers, dimensions and materials separately.
Part numbers must be traceable to the model, installation position and drawing revision. Without reliable evidence, inferred numbers are not published. Submit an OEM or third-party number for cross-checking.
Provide the full model, serial number, OEM or third-party number, drawings, used-part photos, material and operating conditions. These support part identification, material assessment, manufacturing matching, quality control and finished-part delivery.
