Products & Technologies
Shafted Screw Conveyors
CEMA-compliant shafted screw conveyors for horizontal and inclined transport of bulk materials including wastewater biosolids, industrial sludges, agricultural grains, and dry bulk chemicals. Available in custom lengths, diameters, and material configurations.
Shaftless Screw Conveyors
Shaftless screw conveyors excel at transporting wet, sticky, and fibrous materials that wrap around center shafts — ideal for wastewater biosolids, municipal solid waste, and industrial sludge applications where conventional screw conveyors would clog.
