Screw conveyor systems transfer materials using mechanically operated screw blades, unlike Pneumatic conveying which utilises air pressure. The primary function of a screw conveyor is to convey bulk materials or liquids, usually from upstream equipment such as a screw feeder or rotary valve. Screw conveyors consist of a trough or tube containing a spiral screw blade wrapped around a central shaft, when operating, the screw spins driving the material through the enclosed passage.
Typically Screw conveyors are used horizontally or at a slight incline of up to 45 degrees, however when plant space is a premium, a vertical screw conveyor design can help. In these instances a vertical screw elevator should be used. Screw elevators are commonly used for storage silo and hopper discharge, in a wide range of industries including food and waste processing, food manufacturing and aggregates.
The range of screw conveyor systems at SN Engineering account for materials at extreme temperatures, diverse material substances and corrosive materials. Depending on your processing requirements, the team at SN Engineering are always happy to discuss bespoke projects and requirements, to account for plants and spaces of all sizes.
