What is the difference between screw feeder and ordinary screw conveyor?

The biggest feature of the screw feeder is that it is a precision feeding machine with quantitative material and constant speed of movement. More suitable for continuous metering and batching. It will weigh and measure the material during the process of transporting the material to ensure that the material is on the specified value. A speed sensor is installed on the machine to control the moving speed of the material, so as to realize the quantitative feeding and feeding requirements. The ordinary screw conveyor is mainly responsible for the function of transporting materials, with a large conveying capacity, and there is no excessive refinement requirement in the conveying process.

?one. shape size difference

?The screw feeder has beautiful appearance, small screw pitch, small length, and small body. Most of them are inclined 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.

Ordinary screw conveyors are larger in size, most of them are placed in parallel, and some are inclined or vertical. The tubular and U-shaped fuselages are more common.

two. Transport material difference

Although screw feeders and ordinary screw conveyors have many types of materials and are similar, there are also differences between them. Due to physical and model reasons, the materials transported by the screw feeder belong to the light industry (such as feed, fine powder, etc.), and the materials transported by the ordinary screw conveyor can transport cement, coal, fertilizer, etc., with a certain weight. To put it simply, the feeding of the screw feeder has certain limitations, and the ordinary screw conveyor is more inclusive of the transportation of materials.

?Four. Transport volume and work efficiency

Compared with ordinary screw conveyors, the screw feeder has a small body and a small capacity, and its conveying capacity is small, but its work efficiency is high. Ordinary screw conveyors have enough transportation space, large conveying capacity and high work efficiency.
