Screw Conveyor

Screw Conveyor

A transportation equipment that uses the driving device to drive the screw and move the material to achieve the purpose of transportation.
【 Capacity 】:
Xinhai screw conveyor can be customized according to actual working conditions and customer requirements.


Simple structure, small cross-sectional dimensions;

Good sealing and reliable operation, convenient for central loading and unloading;

The conveying direction can be reversed, or be opposite simultaneously;

The materials can be stirred, mixed, heated and cooled in the transportation process;

The material flow can be adjusted through the handling gate;

Large unit power, keep the sealing of the material groove and appropriate clearance between screw and shell.

【Product Structure】

The screw conveyor is composed of the closed tank box and screw. The material in the tank body is pushed out by the screw rotation. The weight of the material and the friction resistance of the chassis to the material make the material not rotate with the blade of the screw conveyor.

【Successful case】

Screw Conveyor-case

Xinhai Mining provided the mineral processing EPC+M+O service for a gold mine tailings cyanide removal project in Mongolia. In the stage of material transportation, Xinhai Mining customized the belt conveyor and screw conveyor two kinds of conveying equipment for this project. Among them, the screw conveyor has the good and reliable working state, easy to central loading and unloading. Besides, the transport direction of spiral conveyor can be reverse, or opposite at the same time, which greatly improved the transportation efficiency of materials.
