Technical Characteristics of Screw Conveyor

It is composed of a driving device, a closed tank and a screw. The coal in the tank is pushed and output by the rotation of the screw .

The screw conveyor is characterized by simple structure, small cross-sectional size, good sealing, reliable operation and low manufacturing cost. It is convenient for intermediate loading and unloading. The conveying direction can be reversed or transported to the opposite two directions at the same time. Materials can also be stirred, mixed, heated and cooled during transportation. The material flow can be adjusted through the loading and unloading gate. However, it is not suitable to transport perishable, viscous, caking and large materials. In the process of conveying, the materials are easy to be broken, and the spiral and chute are easy to be worn. The unit power is large. In use, the sealing of the material groove and the appropriate gap between the screw and the material groove shall be maintained.

Vertical screw conveyor is suitable for short distance vertical conveying. The screw of flexible screw conveyor is composed of flexible shaft and synthetic rubber blade, which is easy to bend. It can be arranged arbitrarily according to the site or process requirements for space transportation. The blades of screw conveyor have on-site pulling type and integral pulling loss. The on-site pulling type can be made into any thickness and size, and the integral pulling type is not suitable for making non-standard screws.

From the perspective of the displacement direction of conveying materials, Hongtai screw conveyor is divided into two types: horizontal screw conveyor and vertical screw conveyor. It is mainly used for horizontal conveying and vertical lifting of various loose materials such as powder, granular and small pieces. This screw conveyor is not suitable for conveying special materials that are easy to deteriorate, viscous, easy to agglomerate or high temperature, afraid of pressure and corrosive.

Screw conveyor is generally composed of conveyor body, material inlet and outlet and driving device; The spiral blade of screw conveyor has three forms: solid spiral surface, belt spiral surface and blade spiral surface. Among them, the blade spiral surface is relatively less used and is mainly used to transport materials with high viscosity and compressibility. This spiral hanging surface type has the functions of mixing and mixing materials during the completion of conveying operation.

Compared with other conveying equipment, screw conveyor has the advantages of small section size, good sealing performance, stable and reliable operation, multi-point loading and unloading in the middle, safe operation and simple maintenance.
