Enclosed Helical Transport for Powders, Granules & Bulk Solids
The TSC Series Tubular Screw Conveyor provides dust-tight mechanical transport for dry, granular, or powdery materials within a fully enclosed cylindrical casing. Driven by an internal rotating helical flight, it moves bulk solids horizontally or at inclines up to 60° while maintaining over 99% dust containment. Available in carbon steel and hygienic AISI 304, 316L, or 321 stainless steel grades, the TSC Series protects against spillage, material loss, and workplace contamination.
