Portable Screw Conveyor

Introduction of Portable Screw Conveyor

The portable screw conveyor is a special design form of the conventional screw conveyor. The purpose is to more easily adapt to the transportation occasions where the transportation site changes frequently or only temporary transportation needs. The portable design realizes the flexibility of the application and more possibilities sex. The portable screw conveyor can be used for both outdoor and indoor applications. The tiltable design enables it to be used in loading vehicles or transporting materials in three-dimensional spaces, or to realize the connection between two devices.

Portable screw conveyor can complete centralized conveying, separate conveying, mixing, dehydration, custom batching, unloading, stacking, and use with other conveying equipment.

Type

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 industries with relatively strict sanitary conditions such as food and medicine.

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 ( Can be customized according to your production site conditions)

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, it overcomes the friction force between the material and the surface of the spiral, as well as the component force that slides down the spiral caused by the material's own weight. Lift up. The lifting height is generally not higher than 5 meters.

Application

Portable screw conveyors are used in a wide range of industrial and agricultural applications where the need for material transport may arise in different parts of a facility or across multiple locations. Some of the common applications of portable screw conveyors include:

Agriculture: Commonly used to transport grain, seeds and other crops. They can be used to transfer material from storage bins to trucks or vice versa, providing efficient and flexible material handling solutions.

Construction: For conveying concrete, sand and other construction materials in construction projects. They can be easily moved from one location to another and can transport materials to hard-to-reach areas.

Manufacturing: Can be used in manufacturing factories to transport raw materials, finished products and scrap. They can be customized to meet specific material handling requirements and can be easily moved to different parts of the plant as needed.

Mining: Can be used in mining operations to transport ore, minerals and other materials. They can be used to transport material from a mine to a processing plant or from one part of a processing plant to another.

Food processing: used to transport food raw materials, finished products and waste. They can be designed with food-grade materials and can be easily cleaned to meet hygiene requirements.

Features and Benefits

1. The universal wheel installed at the bottom of the Portable Screw Conveyor can rotate 360°, and can be braked and fixed during conveying operation, which can flexibly adapt to the conveying scene of unfixed position.

2. Inclined or vertical conveying, any angle within 30~90° can be customized, usually the inclination angle does not exceed 45°.

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 shell is connected by steel pipes through flanges, and the parts are connected as a whole, with good sealing performance, which will not pollute the site or cause material waste when conveying powder.

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.
