Start with the MQG series, complete nameplate and shell dimensions, then identify shell, end and grate-discharge parts, trunnion parts, bearing bushes, gear-drive parts, materials and inquiry requirements.
This page follows CITIC HIC's published MQG nominal-diameter series and connects the shell, end, grate-discharge, trunnion, support and drive parts.
Confirm shell length, discharge arrangement, supports and drive configuration from the complete model, nameplate and installed-equipment drawings.

The system covers shell liners, lifters, end liners, grates, feed parts, trunnion liners and grinding media. Wet-mill pulp lifters are not assumed to suit the dry-discharge arrangement.
Shell Liner / Shell Plate
Protects the shell interior and works with lifters to control the movement of grinding balls and material. Confirm the arrangement, curvature, thickness, hole spacing, shell diameter, rotation direction and adjacent liners.
View Part Details →
Lifter Bar / Lifter Plate
Lifts grinding balls and material and controls their trajectory. Confirm lifter height, profile, pitch, arrangement, hole pattern, shell diameter and rotation direction.
View Part Details →
End Liner / Head Liner
Protects the feed-end or discharge-end head. Confirm the end, inner or outer ring, segmentation, curvature, hole pattern, rotation direction and interfaces with the throat or discharge 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 feeder interface.
View Part Details →
Discharge Grate / Grate Plate
Controls the passage of correctly sized material while protecting the discharge end. Confirm aperture shape, open area, segmentation, curvature, hole pattern, rotation direction and plugging or wear records.
View Part Details →
Mill 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 →
Grinding Balls / Steel Balls
Grinding media subjected to repeated impact and wear. Confirm diameter distribution, ball consumption, mill size, speed, ore hardness, corrosion and breakage rate.
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 mill trunnion and carries radial loads. Confirm journal diameter, bush inside and outside diameters, width, oil grooves, contact pattern, clearance, bearing housing and lubrication.
View Part Details →
Girth Gear / Ring Gear
Meshes with the pinion to transmit the main drive. Confirm module, tooth count, pressure angle, helix angle, split joint, center distance, backlash and contact pattern.

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 →CITIC HIC's published MQG range covers MQG-09 through MQG-45. Confirm the specific shell length, discharge arrangement, supports and drive configuration from the complete model and installed-equipment drawings.
Do not assume interchangeability. Dry discharge, ventilation and material conditions differ. Confirm the general arrangement, grate, discharge structure, rotation direction, drawing and drawing revision.
Submit the nameplate, shell diameter × length, general arrangement, photographs of the grate and discharge area, liner arrangement and key dimensions to assess identification, reverse engineering and manufacturing requirements.
Provide the complete model, shell diameter × length, serial number, liner layout, drawings, used part photographs, materials and duty. We coordinate identification, material assessment, manufacturing selection, quality control and finished part delivery.
