Scraper Conveyor

Product Overview Scraper conveyor is a fixed continuous bulk material handling equipment. The circulating scraper chain drives scrapers to push materials forward inside the closed trough. It is specially designed for horizontal or small-inclination conveying to realize enclosed material transfer.

Featuring sealed conveying performance, the unit adopts scraper chain and flight blades to transport bulk materials inside the trough. It is widely adopted for continuous transfer of powder, granular and small block bulk solids.

Main types include horizontal scraper conveyor and inclined scraper conveyor. Carbon steel trough is standard; stainless steel trough and wear-resistant liner plate options are available for ordinary, damp and mildly corrosive working conditions.

Main Structure & Key Features Scraper chain assembly: The scraper chain with flight blades is the core working component to push materials. Single-chain, double-chain and heavy-duty chain types are selectable for different materials and capacities.

Trough assembly: Closed steel trough with wear-resistant liner. Fully enclosed design reduces dust emission and material leakage, meeting environmental protection requirements.

Drive unit: Motor-reducer assembly supplies power. Sprockets drive the circulating scraper chain; tensioning device keeps the chain running stably.

Sealed material passage: Fully enclosed trough structure effectively controls dust, suitable for dust-sensitive production sites.

Compact layout: Occupies small space and can be arranged flexibly along production lines.

Typical Application Commonly used in grain, mining, chemical, fertilizer, metallurgy and environmental-protection industries for bulk material transport. Suitable for conditions as below: Enclosed conveying where dust control is required; Conveying powder, granules and small lump materials such as grain, coal powder, mineral powder and chemical pellets; Indoor bulk material feeding and transfer operations; Material conveying with high requirements for dust isolation.

Selection Notes Define material properties: particle size, bulk density, abrasiveness, moisture and viscosity to decide chain type, flight style and trough liner. Confirm required conveying capacity, conveying distance and inclination angle. The actual throughput will decrease with the increase of inclination angle. Not recommended for extra sticky materials that may cause chain jamming. Clarify working environment (indoor or outdoor), confirm anti-rust and dust-proof requirement. Check whether inlet hopper, discharge gate and speed regulation function are needed.

Conclusion With excellent dust sealing performance, stable pushing conveying and reliable operation, scraper conveyor is an ideal solution for enclosed bulk material transfer. Stable material transfer can be achieved when properly matched with material characteristics and site conditions.
