A screw conveyor is a device that relies on a motor to drive the screw to rotate, and materials are carried to a certain height through the rotation of blades. The screw conveyor consists of a main shaft, blades, conveying pipe, motor, hopper, and bracket, and is suitable for conveying granular materials in industries such as food, chemical, plastic, and agriculture.

Spiral conveyors are divided into parallel conveying, inclined conveying, and vertical conveying according to their conveying methods. They are classified into carbon steel, stainless steel, manganese steel, etc. according to their materials. There are also two types of cylindrical powder pipes and U-shaped pipes, which are suitable for conveying powdered and granular materials in industries such as food, pharmaceuticals, chemicals, and plastics.

A screw conveyor is a mechanical device that uses an electric motor to drive a screw to rotate and move materials to achieve conveying purposes. Spiral conveyors can transport horizontally, obliquely, or vertically, with advantages such as simple structure, small cross-sectional area, and good sealing. In terms of conveying form, they are divided into axial screw conveyors and non axial screw conveyors, and in terms of appearance, they are divided into U-shaped screw conveyors and tubular screw conveyors.

U-shaped screw conveyors are divided into two types: axial and non axial: axial screw conveyors have a central shaft, which is suitable for conveying materials that are not easy to stick and have certain friction. The wear resistance of screw conveyors has certain requirements, and the shaft and internal bearings for conveying screws in non axial conveyors do not exist. This eliminates the problems of material accumulation and flow blockage. Therefore, the axial screw conveyor is suitable for conveying materials with high viscosity, high moisture content, and poor fluidity, such as sludge, garbage, etc.

At present, there are many types of conveying equipment on the market, such as screw conveyors, belt conveyors, chain plate conveyors, bucket elevators, etc. Today, we will learn about screw conveyors, which industries they are suitable for, and what materials are suitable for selecting screw conveyors.

Screw conveyor is a continuous conveying equipment that uses spiral rotation to move materials. It is suitable for conveying flour, grain, cement, fertilizer ash, sand, gravel, coal powder, small coal and other materials. Screw conveyor is not suitable for conveying perishable, viscous, easy to clean and fast materials. Pipe type screw conveyor is generally used for conveying materials at large angles and can also be used for horizontal conveying.

Spiral feeder, also known as powder feeder, powder elevator, etc., is a device that lifts powder and small granular materials to a fixed height in a spiral manner. It is used in combination with dryers, dryers, etc., to spirally transport raw materials from a low place to a high place. The powder screw elevator (screw feeder) produced by our company is made of 202/304 stainless steel and meets the hygiene standards. The screw elevator has the characteristics of fast feeding speed and stable operation. It can be customized according to the different needs of customers with various heights and lifting capacity feeders, and some functions can be added.
