En-masse chain conveyors (also known as scraper conveyors or drag chain conveyors) for horizontal, inclined, and vertical bulk material transport. Uses scraper chains in closed rectangular casings for reliable, dust-free conveying.

Fully enclosed rectangular casing prevents material spillage and dust emissions. Meets strict environmental regulations for clean workplace operation.
Flexible layout with configurable feed and discharge points along the casing. Ideal for complex process routes requiring intermediate material handling.
Wear-resistant chain designs and optional heat-resistant liners for conveying abrasive materials (ash, slag, clinker) and high-temperature applications.
Bidirectional conveying capability allows material transport in either direction, adding flexibility to process layout and system design.
Simple chain-and-sprocket drive mechanism with easy-to-replace wear parts. Inspection ports along the casing for quick access without disassembly.
Small cross-section profile compared to belt conveyors of equivalent capacity. Fits into tight spaces and multi-level plant layouts.
Coal feeding to boilers, bottom ash removal, fly ash conveying in thermal power plants. Withstands abrasive ash and high-temperature environments.
Raw meal, clinker, and cement powder conveying between process stages. Sealed design prevents material loss and contamination.
Safe, sealed transport of chemical powders and granular materials including soda ash, carbon black, pigments, and catalysts.
Gentle en-masse conveying for grain, oilseeds, and biomass materials. Low material degradation compared to pneumatic systems.
Handling of wood chips, rice husk, bagasse, and other biomass fuels. Explosion-proof configurations available for combustible dust.
RDF (refuse-derived fuel) and MSW conveying with heavy-duty chain designs for irregular, bulky, and abrasive waste materials.
An en-masse (or scraper/drag) chain conveyor moves bulk material inside a fully enclosed rectangular casing using a continuous chain fitted with scrapers. The scrapers push the material as a solid "en-masse" column, so it conveys horizontally, on inclines, and even vertically with minimal turbulence and dust.
It handles abrasive and high-temperature bulk solids such as coal, ash, clinker, cement, soda ash, grain, biomass, wood chips, and chemical powders. Wear-resistant liners and heat-resistant chains are available for harsh duty.
MS is the horizontal type, MC is the inclined type, and MZ is the vertical / Z-type (en-masse) unit. They share the same enclosed casing principle but differ in layout to suit horizontal, inclined, or vertical conveying routes.
Capacities range from 6 to 500 t/h depending on material and casing size. Maximum horizontal conveying length is about 80 m and maximum vertical lift about 40 m; longer or higher layouts can be achieved with multiple units.
Yes. The casing is fully sealed for dust-free operation. Explosion-proof configurations with pressure-relief panels and anti-static components are available for combustible dust such as grain, flour, and wood waste.
Chain conveyors have a smaller cross-section, sealed dust-tight casing, multiple inlets/outlets, and can run horizontally, inclined, and vertically in one unit. Belt conveyors are better for very long-distance, high-speed horizontal transport of non-abrasive materials.
