COMMON MECHANICAL SPARE PARTS IN A CEMENT PLANT

1. Crusher Spares

Critical wear and replacement parts of crushers for efficient crushing of raw materials.

• Hammers, Blow bars, Jaw plates, Liners
• Rotor assemblies, Bearings, Grizzly bars
• Toggle plates and seats

Working:

Breaks limestone, clay, shale into smaller pieces for processing.

2. Raw Mill / Cement Mill Spares

• Liners, Grinding media, Mill internals
• Girth gears, Pinions, Trunnion bearings

Working:

Raw Mill grinds raw materials into raw meal. Cement Mill produces finished cement.

3. Kiln Spares

• Tyres, Rollers, Girth gears, Seals
• Support bearings, Thrust rollers, Chains

Working:

Rotary kiln heats raw meal (~1450°C) to form clinker.

4. Cooler Spares

• Grate plates, Fans, Crusher hammers
• Roller bearings, Hydraulics

Working:

Cools clinker rapidly from 1450°C to ~100°C, improving energy efficiency.

5. Conveyor System Spares

• Belts, Idlers, Pulleys, Scrapers
• Gearboxes, Motors, Chains

Working:

Ensures smooth transport of limestone, clinker, gypsum, and cement.

6. Rotary Equipment Spares

• Seals, Couplings, Bearings, Sleeves
• Shaft assemblies

Working:

Maintain rotating machinery like kilns, mills, fans, compressors, and dryers.

7. Gearbox & Drive Spares

• Gears, Bearings, Shafts, Housings
• Lubrication systems

Working:

Gearboxes reduce speed & increase torque. Drives control speed and torque.

8. Hydraulic & Pneumatic Spares

• Cylinders, Pumps, Valves
• Filters, Hoses

Working:

Hydraulics use oil for high-force tasks, pneumatics use compressed air for fast operations.

9. Miscellaneous

• Fasteners, Gaskets, Expansion joints
• Heat exchangers, Valves & flanges
