Screw feeder Screw weighing feeder is a mechatronics product that combines automatic weight weighing, PLC automatic control and screw conveying mode to realize continuous conveying of bulk materials and dynamic metering, and automatic control feeding. The single-tube screw weighing feeder is a screw weighing feeder with only one spiral tube, and the conveying and weighing and measurement of materials are completed in one spiral tube. The material is discharged from the container or storage silo and conveyed by a screw conveying mechanism with a steady flow, while accurate weighing is carried out by the weighing system, and then the material is accurately fed according to the preset proportion and flow rate. 
The characteristics of the single tube screw weighing feeder are:
1. The size is small, the structure design is exquisite, it is easy to install and displacement, and the installation space requirements are relatively small.
2. Metering and feeding at the same time, material conveying and metering can be completed in a spiral tube, saving application space and cost.
3. The advanced steady flow technology is used to ensure the smooth transportation of materials, reduce the possibility of material agglomeration or blockage of the spiral pipe, and ensure the stable application and measurement control accuracy.
4. It has stable working performance and high reliability, and can continue to operate stably for a long time to ensure the smooth progress of production.
5. The control instrument has a communication interface and can communicate with other host computers. The operation interface of the control instrument is also very simple, which is convenient for on-site operators.
The applications of the single tube auger weigher feeder are:
1. Application industries and materials: In agriculture, environmental protection, food, chemical, cement, steel and building materials and other industries, it can be used to convey and measure the feeding of various powdery, small particles and small lump materials, such as flour, grain, fertilizer, pulverized coal, etc. However, some large, high-viscosity materials are not suitable.
2. Applications: It is suitable for industrial production operations that require quantitative feeding, such as chemical, food and other manufacturing industries, for raw material feeding and batching on the production line; In the field of environmental protection of solid waste disposal, the amount of waste disposed of can be counted. There are also some loading operations that can also be completed with feeders to achieve fast, efficient and accurate loading.
