Operation and Maintenance

Our comprehensive plant operation and maintenance services are meticulously designed to optimize cement plant operations, ensuring maximum efficiency and advanced maintenance practices. By entering an O&M contract, cement plant owners can benefit from guaranteed output at a predetermined price per ton based on performance metrics.

In a market characterized by an oversupply of products and rising operating costs, operational efficiency plays a crucial role in maintaining profitable margins. Our O&M support safeguards your investment from costly operational outages and optimizes fuel consumption.

This contractual arrangement reduces the project owner's responsibilities regarding basic provisions, while we assume full responsibility for ensuring that the plant runs smoothly and achieves the targeted annual production levels. Furthermore, we are committed to enhancing site readiness to address any design or installation errors and to delivering the plant in optimal working condition upon contract completion.

Full technical management of the plant provides five key benefits:

• Responsibility for the plant’s technical performance is assumed.
• Performance levels are guaranteed and linked to operating costs.
• Equipment reliability is enhanced, extending the plant's lifespan.
• Continuous technical support and online monitoring are provided by ASEC back offices.
• The risk of variable cost fluctuations for the client is reduced.

Indirect benefits include minimal investment protection, and our services within the technical management framework adhere to the best standards and practices. These include:

• Planning and managing operational functions: production, maintenance, inspections, preventive maintenance, and quality control.
• Implementing management systems across all operational areas, including inventory management, storage, and spare parts.
• Enhancing human resources management practices and ensuring compliance with international standards, including recruitment, training, and team replacements.

We recognize the critical importance of efficient shutdown maintenance in cement plants. To ensure continuous operations and maximum efficiency, periodic shutdown maintenance is essential. Our shutdown services are designed to minimize downtime, enhance safety, and optimize plant performance. 

These services include:

• Complete kiln section replacements, overhauls, and replacement of kiln accessories and bearing components (girth gear, roller bearings, nose rings, etc.).
• Grinding and alignment of riding rings and girth gear systems.
• Replacement of internal piping, ductwork, sheet metal components, cyclone roofs, and refractory works.
• Overhaul of tube mills, including diaphragm lining, bearing replacement, girth gear maintenance, and duct, cyclone separator, and crusher lining.
• Maintenance of separators and crushers.
• Overhaul of different cooler types.
• Maintenance of hydraulic systems and accessories.
• Replacement of rotors and parts for limestone and clay crushers.
• Overhaul and maintenance of various types of limestone reclaimers, including belt conveyor repairs (cold and hot vulcanizing) and preheater brick and castable work.
