Screw Conveyor
The basic principle of the screw conveyor remains unchanged today from when Archimedes first used an internal type helix to remove water from the hold of a ship. With the technological innovations of the past century and a great deal of research in the field, screw conveyors have become precision pieces of equipment that can move materials either horizontally, on an incline or vertically. They can be used as feeders, distributors, collectors or mixers and can be equipped to either heat or cool while performing the task. With proper covers and gaskets they become weatherproof, dust tight and rodent proof. Their compact design allows them to fit easily into restricted areas that would otherwise be unsuitable for most types of bulk material handling equipment. They are simple to install and support and require very little maintenance. Per foot, they are undoubtedly one of the most economical types of bulk material handling equipment available today.
Types –
Screw conveyors are used for positive displacement/ handling of free flowing as well as lumpy materials over a distance, while screw feeders are used for controlled feeding of free flowing material (taken out as a discharge from a container) to a bin for volumetrically controlled or weight controlled quantity by way of changing rotary speed of the feeder.
We manufacture screw conveyors in various profiles as per demand of the process such as –

Materials of Construction –
Generally screw conveyors and feeders are manufactured in MS, IS- 2062 GR-A, carbon steel, stainless steel SS304 and other grades as per demand of the customer. We make U-Trough type or enclosed tube type screw conveyors as per requirement of the process. These can be supplied in a wide range of diameters (50mm- 600mm) and length as long as 40 meters, in M.S. or S.S. construction.
Our production facilities have also kept pace with inherent advancements in design. Numerous specialty machines have been designed and methods have been devised that help assure and control manufacturing tolerances; thus providing for interchangeability of parts, greater ease of assembly, smoother operation and longer life.
