Scraper Conveyor

1. Overview

The Scraper Conveyor is a continuous drag-type conveying equipment designed for abrasive, high-temperature and large-particle bulk materials. Different from screw conveyors, it adopts a circulating endless chain assembly with integral scrapers to push materials along the closed trough. The fully enclosed body prevents dust leakage and material spillage. With strong traction force, high temperature resistance and stable operation under heavy load, it is the ideal solution for harsh working conditions such as mining, industrial clinker, ash slag and bulk mineral transportation.

2. Working Principle

The drive head sprocket drives the high-strength circular scraper chain to run cyclically. After materials fall into the feeding trough, the rigid scrapers generate continuous traction force to drag the material layer forward along the trough liner. Thanks to the internal friction between material particles, the whole material moves integrally without scattering. The return section adopts lower track guiding to avoid chain deviation. Materials are discharged at the designated outlet, realizing stable, long-distance and multi-point feeding/discharging conveying in complex layouts.

3. Core Features & Advantages

- Fully Enclosed & Eco-Friendly: Welded sealed trough structure achieves zero dust emission, compliant with modern environmental protection discharge standards.

- High Temperature Resistance: Special heat-resistant chain and liner design, suitable for materials up to 280°C such as clinker and hot slag.

- Powerful Traction Capacity: Thickened high-strength scraper chain bears heavy load, stable conveying for large-particle and abrasive materials.

- Multi-Point Feeding & Discharging: Support multiple inlets and outlets, flexible layout for complex production line routing.

- Low Material Damage Rate: Integral dragging movement without screw extrusion, protecting material original particle shape.

- Durable & Low Maintenance: Replaceable wear-resistant liner and heat-treated chain, long service life and easy replacement of wearing parts.

- Anti-blocking & Stable Operation: Optimized trough cross-section and chain tensioning system prevent jamming and chain deviation.
