What is the difference between screw conveyor and screw feeder?

Screw conveyors and screw feeders are common material conveying equipment, and their differences are mainly in the following aspects:

1. Different functions: the screw conveyor is mainly used to transport various bulk, powder or small block materials such as cement, grain, chemical fertilizer, etc. within a long distance. The screw feeder is used for quantitative feeding or continuous uniform feeding of powdery or small granular materials, such as coal powder, cement, granular materials, etc.

2. The structure is different: the screw conveyor is usually composed of a screw body, a feed port, a discharge port, a transmission device, a bracket, etc., and the screw body can be configured with a single head or a double head according to different needs. The screw feeder is generally composed of a hopper, a screw rod, a transmission part, a control system, etc., and the hopper generally has a batching valve for adjustment and control.

3. The location of the equipment is different: the screw conveyor is generally located at the end of the production line, and is used to transport the materials produced on the production line to containers or vehicles for storage or transportation. The screw feeder is generally used as the starting point of the production line to quantitatively feed the raw materials to the next process.

4. Different scope of use: Since the screw conveyor can transport materials of various specifications, its scope of application is relatively wide, and multiple devices can be expanded to work. The screw feeder is generally suitable for conveying quantitative and uniform granular materials, so its application range is relatively narrow.

In general, screw conveyors and screw feeders are different in function, structure, equipment location, and scope of use. Users should consider comprehensively according to the characteristics of materials and conveying requirements when choosing to use, and choose the one that suits them. equipment.
