20+ YRS Proven Experience

High Durability

Constructed from SANS 50025 Grade S 355 JR steel with VRN500 wear-resistant linings in high-impact zones for maximized longevity.

Optimized Trough

Maximizes storage capacity with efficient incline angles, optimized trough to enhance dewatering.

Advanced Drive

Utilizing single-motor or electro-hydraulic drive systems to ensure consistent performance under heavy load and backlog conditions.

Flow Efficiency

Engineered transfer points and specialized scraper cleaning systems minimize blockages and carryover for continuous operation.

Removable SSC Configuration
// Plant Integration

Adaptable Geometries

The SSC is mounted on rails with wheels, so the entire unit can be rolled or winched out from under the boiler.

Key design considerations include precise boiler-to-trough sealing and effective ash cooling, ensuring safe and efficient handling even in the most demanding coal-fired boiler environments.
