Business Solution Overview
Supports Mechanised Coal Handling: The conveyor is designed to achieve mechanisation of coal falling, loading and transportation in underground working faces. This helps mines move away from more manual handling methods and improve operational continuity.
Built for Underground Mine Conditions: The machine is specifically described for coal mine working faces and tunnels, including thin and medium-thick seams and inclined blasting faces. Features such as reverse running and adaptation to uneven bottom plates support practical underground use.
Continuous Conveying Performance: The product description highlights low failure rate and continuous conveying. For coal operations, this supports steadier material flow and reduced disruption across the production cycle.
Flexible Model Coverage: With listed capacities of 40 t/h, 60 t/h and 80 t/h, the range can suit different production requirements and mine layouts. This gives operators options for matching conveyor performance to seam conditions and transport demands.
Maintenance-Friendly Design: The conveyor is described as easy to maintain, with a compact structure and simple operation. These characteristics can help simplify routine servicing and day-to-day underground operation.

Why Choose Underground Chain Scraper Conveyor for C?
Three-Part Conveyor Structure
The scraper machine is composed of nose, middle and tail sections for a clear and practical underground conveyor layout. This structure integrates the drive, conveying and return functions into one system.
Simple Installation and Operation
The product description highlights compact structure, simple operation and fast installation. This makes it suitable for underground environments where setup efficiency matters.
Continuous Conveying with Low Failure Rate
Designed for continuous coal transport, the conveyor is described as having a low failure rate. This supports more stable material movement in working faces and tunnels.
Reverse Running Capability
One model can run in reverse, which helps when handling bottom chain accidents. This adds operational flexibility in underground coal mining conditions.
Adaptable to Uneven Mine Floors
The conveyor can adapt to uneven and curved bottom plates in coal mining faces. It can also withstand vertical and horizontal bending of goods as described.
Multi-Function Mine Face Use
One listed model can also serve as a track for coal mining machine operation and as a fulcrum for the front end of the liquid night stand. This supports broader use at the mining face.
