Maintainance

Cement plant Mechanical Maintenance

Mechanical maintenance in a cement plant covers the main production areas, rotating equipment, utilities, and the support systems that keep the line operating safely and reliably.

Quarry and crushers area

• Inspect crushers, transfer points, chutes, and wear parts.
• Check vibration, lubrication, and alignment on drive units.
• Watch for spillage, dust build-up, and feeder issues.

Reclaiming and stacking station

• Check bucket wheels, stacker/reclaimer drives, rails, wheels, and guide rollers.
• Inspect lubrication, alignment, and structural wear.
• Keep an eye on material flow and belt or chain tracking.

Raw mills area

• Inspect apron feeders, raw mill drives, mill bearings, diaphragms, liners, and lubrication circuits.
• Check gearbox condition, backlash, vibration, and temperature.
• Verify the condition of mill body, trunnions, and hydraulic systems.

Kiln area

• Inspect kiln shell, tyres, rollers, seals, thrust system, girth gear, pinions, and drive train.
• Monitor alignment, gear mesh, lubrication, and roller bearing condition.
• Check the preheater tower and feed-lifting systems connected to kiln operation.

Clinker cooler

• Inspect grate cooler drives, hydraulic systems, hammer crusher, and discharge mechanisms.
• Check wear on grate plates, fans, and bearings.
• Watch for overheating, air leakage, and material build-up.

Clinker transportation and clinker silos

• Inspect pan conveyors, drag chains, buckets, rails, wheels, guide rollers, and drive gearboxes.
• Check silos, spillage points, and transfer paths.
• Verify smooth clinker flow and avoid choking points.

Cement mill area

• Inspect ball mills, mill heads, bearings, liners, diaphragms, and drive systems.
• Check vibration, lubrication, alignment, and wear.
• Keep an eye on auxiliary systems such as feeders and conveyors.

Maintenance of gearboxes

• Check vibration, oil condition, bearing temperature, backlash, and tooth contact.
• Inspect shafts, housings, seals, couplings, and alignment.
• Repair pitting, broken teeth, and lubrication issues promptly.

Raw and cement material pumps

• Inspect screw pump bodies, drive units, bearings, and mixing chambers.
• Check discharge flow, wear, and air supply to pneumatic circuits.
• Keep feed consistency stable to avoid blockages and overloading.

Dust collectors

• Inspect filter bags, cages, hoppers, pulsing air jets, ducts, and fans.
• Watch pressure drop, emissions, and cleaning performance.
• Repair leaks and bag damage quickly to protect the line.

Vertical mill

• Inspect grinding table, rollers, hydraulic system, separator, and bearings.
• Monitor vibration, pressure, wear, and output quality.
• Keep lubrication and alignment under control.

Utilities

• Check hydraulic pumps, water pumps, compressors, blowers, and air dryers.
• Inspect electrical motors, couplings, and connected circuits.
• Use routine inspection and preventive work to avoid plant stoppages.
