Screw conveyors are designed for horizontal and inclined (up to 20dgr.) conveying of grain and products of its processing. They are used as a part of production line for silos, mills, groats mills, feed mills, drying and cleaning towers, threshing and cleaning towers and oil mills.

The main advantages of screw conveyors manufactured by Sevkavelevatorspetsstroy Corporation, LLC, against the domestic and foreign analogues are the following:

  • Availability of permit issued by the Federal Service for Ecological, Technological and Atomic Supervision, availability of conformity certificate GOST and hygienic certificate;
  • Reliability of construction;
  • Use of advanced materials and components during production. Bearings are made in Germany and in Japan. Rollers of special series are made of a pipe with use of self-centering bearings. Gear motors are made by Bauer (Germany) and Motovario (Italy).
  • Long-term lifetime of products;
  • Low price against the foreign analogues;
  • No expenses for customs clearance formalities and transportation from foreign countries.

All types of screw conveyors are produced in accordance with Technical Specifications and Gostehknadzor requirements and in accordance with international standards valid for these products. The factory manufactures and supplies spare parts and components for all types of screw conveyors: tension and drive stations, intermediate sections, screws of any pitch and any coiling and other components.

Screw conveyor consists of the following parts: auger formed by spiral surface, welded to the tubular shaft; trough or cylindrical casing with outlet spouts; intermediate (suspended) or end bearing, one of which is thrust; and drive.

Operation concept of screw conveyors is based on continuous conveying grain by rotating auger mounted in fixed trough. There are different slow- and fast-running screw conveyors. In slow-running horizontal and inclined conveyors the product is held from turning by gravity and friction on trough. Raw material coming in the working zone of auger slides along the auger from the loading zone to the discharge zone moving by a spiral. The auger is started by a gear-motor.
