Sand Screw Conveyor

What is a Sand Screw Conveyor?

Sand Screw Conveyor is a device for conveying non-sticky dry powdery and granular materials such as sand. It can be conveyed horizontally, inclined or vertically. Sand Screw Conveyor can be divided into two types: fixed type and mobile type according to the installation method. According to the direction of conveying Or the speed is divided into two types: horizontal slow speed and vertical fast speed. In the actual conveying process, the horizontal slow speed screw conveyor is more commonly used.

Sand Screw Conveyor Application

Sand Screw Conveyor can be used for conveying all kinds of sand, such as: sea sand, mountain sand, river sand, ultra-fine sand, fine sand, medium sand, coarse sand, machine-made sand, etc.

Sand Screw Conveyor Features

1. The conveying distance is long, and the conveying distance of a single machine can reach 60-70 meters;

2. The fully enclosed structure design can ensure that the conveyed materials are not polluted;

3. There is a cleaning device at the discharge end, which can reduce material blockage;

4. The shell is made of seamless steel pipe, and the ends are connected with each other by flanges, which has good rigidity;

5. It can be arranged at different angles according to user requirements.

Principle of Sand Screw Conveyor

The Sand Screw Conveyor is mainly driven by the motor to rotate the screw. When the screw shaft rotates, due to the gravity of the material and the friction with the tank wall, the material can only move forward along the bottom of the conveyor under the push of the blade. Move to realize the conveying of materials.
