INCREASING OF SCREW CONVEYOR CAPACITY

Abstract

Screw conveyors are used for the transmission of powder, small-grained and liquid materials in the different areas of industry. Screw conveyors have rotating helical shafts inside fixed a through or pipe. The goods are delivered with the rotation of screw. The rotational speed of screw shaft is directly related to the transmission capacity. It leads to serious balancing and vibration problems in conveyor because of the increasing rotational speed of screw shaft. The transmission capacity of materials depends on three factors. These are dimension and geometry of conveyor, characteristics of transmitted material. In this study, these parameters and change of flow rate are examined and results are given in tables.
