What is the difference between screw conveyor and screw feeder

Screw Feeder is a kind of screw conveyor, but they are essentially different. Let me tell you about the difference between screw feeder and screw conveyor from the following aspects

Function difference

The biggest feature of Screw Feeder is that it is a precise feeding machine with quantitative material and constant speed of movement. It is more suitable for continuous metering and batching. It can weigh and measure the material during the transportation of the material to ensure that the material is on the specified value. The speed sensor is installed on the machine to control the moving speed of the material, so as to achieve quantification Feed, feed demand.

Screw Conveyor is mainly responsible for the function of material conveying, with a large conveying volume, and there is no too much refinement requirement in the conveying process.

Shape size difference

Screw Feeder has beautiful appearance, small screw pitch, small length, and small body. Most of them are placed in an inclined position to ensure convenient feeding. The design of the feed inlet is relatively obvious. It is a three-dimensional trapezoidal hopper with a wide top and a narrow bottom. The inclined screw feeder is generally a cylindrical body to maintain its airtightness.

Screw Conveyor has a larger body, most of them are placed in parallel, and some are inclined or vertical. The tubular and U-shaped fuselages are more common.

Transport material difference

The materials conveyed by Screw Feeder belong to the light industry (such as feed, fine powder, etc.), and the scope of application has certain limitations.

Screw Conveyor can transport cement, coal, chemical fertilizer and other large quantities of materials with a certain weight. It is commonly used in food, medicine, metallurgy, building materials, chemical industry and other industries, and has a wide range of applications.

Transport volume and work efficiency

Compared with the Screw Conveyor, the Screw Feeder has a smaller body, smaller capacity, and lower conveying capacity, but it has higher working efficiency. Screw Conveyor has enough transportation space, large conveying capacity and high working efficiency.

The above is the difference between Screw Feeder and Screw Conveyor, for reference only!
