A Redler-type multi-directional en-masse chain conveyor uses T- or U-shaped paddle elements attached to a central roller chain — moving bulk solid simultaneously in both the upper (loaded) and lower (return) runs of the casing with a single chain drive. Processing 0.2-50 t/h horizontally, on inclines, vertically, and around multiple direction changes in a single continuous casing path, it enables complex routing of powder and granules between production floors and areas inaccessible to belt or screw conveyors — all within a single dust-tight enclosed circuit.

The T- or U-paddle chain moves at 0.05-0.2 m/s; bulk solid fills the casing around the chain and is carried by en-masse friction in the upper run — rising vertically through enclosed duct sections and continuing horizontally as required. The return run in the same casing carries residual material back to the inlet — ensuring minimal in-system hold-up. Direction changes are achieved with standard casing bends and corner units requiring no additional drive points. A single variable-speed drive controls the entire circuit — simplifying control and minimising maintenance points across complex multi-floor layouts.
