Use current CI711–CI732 models to identify blow bars, impact plates, rotors, bearings, aprons, hydraulic adjustment parts and materials for quotation.
Models and key specifications identify the machine. Wear parts and general spares link to component and material pages. Drawing references remain blank where no reliable match exists.
Weight, maximum feed, capacity and power come from Sandvik's current stationary HSI pages and support initial identification.

|---|---|---|---|---|
| CI732 | 29,650 kg | 350 mm | 250–575 t/h | 440 kW |
| CI731 | 27,750 kg | 1,000 mm | 400–700 t/h | 440 kW |
| CI722 | 16,256 kg | 350 mm | 150–250 t/h | 250 kW |
| CI721 | 16,000 kg | 900 mm | 200–400 t/h | 250 kW |
| CI712 | 11,184 kg | 300 mm | ≤150 t/h | 185 kW |
| CI711 | 11,005 kg | 600 mm | ≤200 t/h | 185 kW |
Actual capacity varies with material, feed grading, rotor speed, bar and apron configuration, gaps and operating conditions.
Identify each position separately. Select materials for impact, abrasion, metal in feed, target particle shape, replacement access and current failure patterns.

View the Component Page →Available traceable records do not provide a publishable part list matched to specific CI711–CI732 models. No speculative references are listed. Submit known OEM or third-party drawings for checking and quotation.
Reference Rules: Before quotation or manufacture, confirm full model, serial number, position, drawing reference/drawing, key dimensions, material and duty. Similar shape does not establish interchangeability.
No. Check rotor slot, bar section, length, weight, lock, working direction, material and matching backing strips or wedges.
Not necessarily. Feed size, impact energy, abrasion, rotor speed, apron stages and gaps all influence bars and liners.
Yes. Send full model, serial number, location, photographs and key dimensions or drawings. We identify the part before confirming supply.
Provide full model, serial number, position, OEM/third-party reference, photographs, drawings, material and duty for identification, material assessment, quality control and delivery.
