Mobile Screw Conveyor

Introduction of Mobile Screw Conveyor

Mobile screw conveyor is to install universal wheel at the bottom of conventional screw conveyor, which is convenient to move and is suitable for the transportation of bulk materials in unfixed positions. It is designed as a separate type, the material box vibrates and the amplitude is adjustable, and it is easy to load and unload. In order to facilitate the cleaning of residual materials, it is designed as follows: the screw can be reversed for discharging, the lower end of the material pipe has a gate for discharging, and the whole screw can be easily taken out. The inlet and outlet of the mobile screw conveyor can be made into the required inclination angle according to the situation of the work site, and it can be connected and fixed with other supporting equipment.

Types of Mobile Screw Conveyor

Mobile screw conveyors can be divided into different materials and conveying angles according to the conveyed materials and site conditions:

1. Classification of different materials

Carbon steel: Q235 carbon steel material, suitable for conveying common materials.

Stainless steel: Made of 304 or 316 stainless steel, it is resistant to acid and alkali corrosion, high temperature resistance of 200 ° C, clean and hygienic, anti-rust, suitable for some industries with relatively strict sanitary conditions.

2. Different angles

Inclination: use the motor to drive the screw to rotate through the reducer, and through the rotation, the material is moved along the fixed casing and conveyed to the predetermined position. The inclination angle is 0-60°, and the conveying length is generally not more than 6 meters ( It can also be customized according to the user's on-site situation)

Vertical: Using the centrifugal force generated by the high-speed spiral body in the vertical circular shell, with the help of the friction force between the material and the shell, to overcome the friction force between the material and the surface of the spiral, and the component force that slides down the spiral caused by the material's own weight, the material is removed. Lift up. The lifting height is generally not higher than 5 meters.

Features and Benefits

1. The universal wheel is installed under the equipment, which can be moved at will, especially suitable for the operation of unfixed position such as bulk material loading.

2. Inclined or vertical conveying, conventional 45 degrees, can be customized at any angle within 30~90 degrees.

3. The conveying capacity can reach 142 cubic meters per hour, and the length can be up to 30 meters when it is inclined conveying, and the height can be up to 5 meters when it is vertically lifted.

4. The outer casing is connected by steel pipes through flanges to connect all parts as a whole, with good sealing performance.

5. The screw motor and the vibration motor are independently controlled. The material box is designed as a separate type. The material box vibrates and the amplitude is adjustable, which is easy to load and unload.

6. The screw can be reversed for discharging, the lower end of the material tube has a gate for discharging, and the whole screw can be easily taken out.
