Start with the MB nominal diameter and project shell dimensions, then identify shell, end and trunnion parts, chutes, grinding rods, bearing bushes, gear-drive parts, materials and inquiry requirements.
This page follows CITIC HIC's published MB nominal-diameter series and project dimensions. Confirm the specific power, throughput and installed configuration from the complete model.
The model suffix identifies the nominal shell diameter. Shell length, discharge arrangement, rod-size distribution, supports, drive and liner arrangement vary by project.
| Model Series | Nominal Shell Diameter | Shell Length | Required Checks Before Manufacturing |
|---|---|---|---|
| MB-15 | 1,500 mm | Confirm against the mill shell length for the project | Nameplate, general arrangement, discharge, liners, supports and drive |
| MB-21 | 2,100 mm | Confirm against the mill shell length for the project | Nameplate, general arrangement, discharge, liners, supports and drive |
| MB-27 | 2,700 mm | Confirm against the mill shell length for the project | Nameplate, general arrangement, discharge, liners, supports and drive |
| MB-32 | 3,200 mm | Confirm against the mill shell length for the project | Nameplate, general arrangement, discharge, liners, supports and drive |
| MB-36 | 3,600 mm | Confirm against the mill shell length for the project | Nameplate, general arrangement, discharge, liners, supports and drive |
| MB-45 | 4,500 mm | Published project dimensions include approximately Ø4.6×6.7 m | Project, nameplate, general arrangement, discharge, liners and drive |
The numbers on the diagram correspond one to one with the rows below.
| No. | Component | Location | Applies to |

| 1 | Mill head | Visible circular head of the second rod mill from the left | Ma'aden project, Ø4.6×6.7m wet rod mill |
The system is organized by installation position and consumable category. Each position has different impact, sliding wear, slurry erosion, corrosion or bending-fatigue conditions, so materials and processes are confirmed separately.
Shell Liner / Shell Plate
Protects the shell interior and controls the movement of grinding rods and material. Confirm the arrangement, curvature, thickness, hole spacing, shell diameter, rotation direction and rod trajectory.

Feed End Liner
Protects the feed-end head and interfaces with the feed trunnion. Confirm inner and outer ring positions, segmentation, curvature, hole pattern, rotation direction and throat interface.
View Part Details →
Discharge End Liner
Protects the discharge-end head and transition area. Confirm inner and outer ring positions, segmentation, curvature, hole pattern, discharge structure, rotation direction and adjacent liners.

Head Liner / End Liner
Entry for end-liner categories. Before manufacture, specify the feed or discharge end, ring layer, segmentation, hole pattern, rotation direction and drawing revision.
View Part Details →
Trunnion Liner
Protects the inner surface of the feed or discharge trunnion. Confirm the end, inside and outside diameters, length, taper, flange, hole pattern, rotation direction and adjacent structure.
View Part Details →
Feed Chute Liner
Protects the feed chute and material-impact zone. Confirm flow direction, segmentation, thickness, curved surfaces, hole pattern, drop height and feed interface.
View Part Details →
Discharge Chute Liner
Protects the discharge and downstream transfer area. Confirm flow direction, segmentation, thickness, curved surfaces, hole pattern, drop height and downstream interface.
View Part Details →
Grinding Rods / Steel Rods
Grinding media subjected to repeated bending, impact and wear. Confirm diameter, length, straightness, size distribution, rod consumption, breakage records, ore and mill dimensions.
View Part Details →Check support and drive parts separately against the complete model, shell dimensions, journal, fits, gear parameters, material, heat treatment, lubrication and inspection requirements.
Trunnion Bearing / Bushing
Supports the trunnion and carries radial loads. Confirm journal and bearing-bush dimensions, width, oil grooves, contact pattern, clearance, bearing housing and lubrication.
View Part Details →
Girth Gear / Ring Gear
Meshes with the pinion to transmit main drive power. Check module, tooth count, pressure angle, helix angle, split joints, mounting distance and contact pattern.
View Part Details →
Pinion
Meshes with the girth gear to transmit motor and gearbox output. Check module, tooth count, pressure angle, helix direction, shaft interfaces, backlash and contact pattern.
View Part Details →A similar diameter is not enough. Confirm the project nameplate, complete model, shell length, discharge arrangement, supports, drive and general arrangement.
No. Also confirm length, straightness, hardness gradient, impact toughness, rod-breakage records, rod-size distribution, mill dimensions, ore and operating conditions.
Submit the nameplate, shell diameter × length, general arrangement, installation position, used-part photographs, rod and wear records, and key dimensions to assess identification, reverse engineering and manufacturing requirements.
Provide the complete model, shell diameter × length, serial number, liner arrangement, grinding-rod specification, drawings, used-part photographs, material and operating conditions. We will use them for identification, material assessment, manufacturing matching, quality control and finished-part delivery.
