Screw Conveyors

Bulk Technik supplies both tubular and trough screw conveyors of various sizes and lengths with drives to match the capacity. The screw conveyors can be installed horizontally or inclined at angles and they can be supplied in mild steel or different grades of stainless steel.

The standard tubular conveyor sizes range from 100 NB to 500 NB with their lengths being limited by the deflection of the internal screw flight shaft. Generally we do not recommend the use of centre bearings forthe tubularscrew conveyors, because these often lead to material blockages and maintenance issues. The tubular conveyors are supplied with a housing that has an inspection hatch on the inlet and discharge side. A screw flight with both a drive and idler shaft is custom designed for the application with specific attention given to the type of spiral that is used (solid, ribbon, tapering, increasing pitch,

Other type of screw conveyors that Bulk Technik can supply include: twin screw conveyors, mixing conveyors, cooling conveyors, reversible conveyors and conveyors with multiple inlets.
