Start with CSM-1120 and the complete installed-equipment documentation, then identify the screw agitator, liners, feed and discharge parts, screens, bearings, seals, materials and inquiry requirements.
This page uses the CSM-1120 listed in CITIC HIC's published project information to organize model identification and spare-part paths. Confirm other installed models and power ratings from project documentation.
CSM-1120 supports installed-equipment searches. Before manufacture, confirm the grinding chamber, agitator, shell, drive, shafting and drawing revision.
| Model | Model Status | Key dimensions | Required Checks Before Manufacturing |
|---|---|---|---|
| CSM-1120 | Listed in CITIC HIC published project information | Grinding chamber, agitator and shell dimensions confirmed by project drawings | Project, nameplate, general arrangement, drive, shafting, liners and drawing revision |
CSM-1120 is the current model entry. Confirm other installed CSM mills separately from the nameplate, project documents and drawings.
Each position is exposed to different high-velocity wear, slurry erosion, localized impact, corrosion or plugging risk, so materials and manufacturing processes are confirmed separately.
Screw / Impeller Agitator
Transfers energy within the grinding chamber and circulates grinding media and slurry. Confirm overall length, diameter, pitch, hand of rotation, shaft interface, segmented construction and installation direction.
Material Selection: Confirm wear-resistant alloy steel, high-chromium cast iron, ceramic or composite wear construction according to abrasive wear, impact, slurry corrosion and maintenance method.

Screw Tip / Flight Tip
Protects the outer edge and high-velocity tip area of the screw flight. Confirm position, left/right orientation or hand of rotation, curvature, thickness, hole pattern, segmentation and agitator interface.
Material Selection: Confirm high-chromium cast iron, wear-resistant alloy steel, cemented carbide or ceramic-composite construction according to localized wear, impact and replacement method.

Mill Shell Liner
Protects the inner wall of the grinding chamber shell. Confirm segmentation, ring level, curvature, thickness, hole pattern, upper/lower position and operating clearance to the agitator.
Material Selection: Confirm high-chromium cast iron, alloy steel, rubber, polyurethane or ceramic-composite liners according to abrasive wear, slurry and impact.

Discharge Pipe Liner
Protects discharge piping against slurry erosion and abrasive wear. Confirm inside and outside diameters, length, bend angle, flange, interfaces, flow direction and replaceable construction.
Material Selection: Confirm high-chromium cast iron, rubber, polyurethane, ceramic or composite pipe liners according to flow velocity, particle size, corrosion and pressure.

Internal Classifying Screen
Located at the internal classification or media-control position. Confirm location, apertures, slot width, outside diameter, thickness, support, orientation and adjacent channels.
Material Selection: Confirm wear-resistant stainless steel, alloy steel, polyurethane or composite screens according to particle size, wear, corrosion and plugging risk.
View Part Details →
Media Separation Screen
Prevents grinding media from entering the discharge system. Confirm slot width, open area, outside diameter, support, installation direction, media size and wear records.
Material Selection: Confirm wear-resistant stainless steel, alloy steel, polyurethane or composite screening construction according to media, wear, corrosion and plugging.
View Part Details →Check bearings and seals separately against the complete model, shaft and housing diameters, fits, tolerances, loads, speed, lubrication, flushing, process medium and temperature.
Bearing Sleeve
Supports the rotating shafting and maintains the specified clearance. Confirm shaft and housing diameters, inside and outside diameters, length, flange, oil grooves, fits, tolerances and lubrication.
Material Selection: Confirm bearing bronze or the original sliding-bearing material according to bearing pressure, speed, temperature rise, slurry isolation and lubrication.
View Part Details →
Shaft Seal
Isolates slurry, dust and lubricant. Confirm shaft diameter, groove, face or lip construction, pressure, temperature, speed, process medium and flushing method.
Material Selection: Confirm NBR, HNBR, FKM, PTFE, polyurethane or mechanical-seal materials according to medium, pressure, temperature and speed.
View Part Details →CSM 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, project, installation position and installed-equipment drawings. OEM drawing numbers and third-party part numbers are checked separately.
CITIC HIC's published project information lists CSM-1120. Confirm other installed models and power ratings from the complete nameplate, project and equipment documentation.
No. Also confirm the complete model, overall length, diameter, pitch, hand of rotation, shaft interface, segmentation, operating clearance, material, process and drawing revision.
Submit the nameplate and project, photographs of the grinding chamber and agitator, general arrangement, installation position, used parts, wear records and key dimensions to assess identification, reverse engineering and manufacturing requirements.
Provide the complete model, project, serial number, grinding-chamber and agitator dimensions, drawings, used-part photographs, materials, media and operating conditions. We will use them for identification, material assessment, manufacturing matching, quality control and finished-part delivery.
