1. PAINPOINT DRIVEN OPENING

Managing a cement plant’s material handling system presents persistent challenges that directly impact your bottom line. Are you experiencing:
Excessive Downtime: Unplanned stoppages due to conveyor belt failures, spillage, or component wear, halting the entire production line and costing thousands per hour in lost output.
High Maintenance Costs: Frequent manual interventions for cleaning, adjustment, and replacement of idlers, rollers, and belts, driving up labor and spare parts expenditures.
Material Spillage & Dust Emission: Fugitive material loss creates safety hazards, increases housekeeping labor by up to 30%, and leads to regulatory noncompliance and environmental penalties.
Energy Inefficiency: Misaligned or poorly tensioned conveyor systems consume excess power, with industry data indicating over 15% of a plant’s electrical load can be attributed to inefficient conveying.
Inconsistent Feed Rates: Unreliable transfer points cause fluctuations in raw meal or clinker feed to the kiln or mill, compromising process stability and final product quality.

How can you achieve reliable, clean, and energyefficient material transport from crusher to preheater to packing plant? The solution lies in specifying highperformance conveyor idlers engineered for the cement industry’s harsh conditions.

2. PRODUCT OVERVIEW: HeavyDuty Conveyor Idlers for Cement Plants

Our product line comprises a complete range of heavyduty conveyor idlers designed for the abrasive and highload environment of cement production. These components support the belt along its entire journey, ensuring smooth material transport of limestone, clay, coal, clinker, and finished cement.

Operational Workflow:
1. Load Reception: Impact idlers at transfer points absorb the shock of falling material (e.g., from crusher discharge), protecting the belt carcass.
2. Carrying Phase: Troughing idlers along the conveyor length form the belt into a trough, maximizing load capacity and centering the material stream.
3. Return & Cleaning: Return idlers support the empty belt on its journey back. Spiral or rubber disc return idlers actively clean sticky material from the belt underside.
4. Transition & Alignment: Transition idlers between troughing and flat sections manage belt stress. Training idlers automatically correct minor belt misalignment.

Application Scope & Limitations:
Scope: Suitable for indoor and outdoor overland conveyors handling all bulk materials in cement manufacturing (ROM limestone to fine cement). Available for belt widths from 500mm to 2200mm.
Limitations: Specific sealing packages are required for applications with extreme fines (e.g., fly ash) or in washdown areas. Maximum recommended ambient temperature is 30°C to +60°C.
