Spiral feeder, also known as spiral feeder, is a production measuring equipment that controls feeding, dynamic metering, and continuous conveying of powdered materials. Spiral scales are divided into single tube single-layer and double tube double-layer structures. The single tube single-layer structure completes both metering and conveying simultaneously, while the double tube double-layer structure achieves stable flow and conveying in the upper layer and metering and conveying in the lower layer. The stable flow effect is better and saves space. The length of the spiral scale can be determined by the actual situation; According to the user, a double tube structure is generally used for material measurement, which requires the installation of a screw conveyor and the simultaneous use of a screw scale to complete material measurement. It is mainly used for measuring powder materials or small particle materials.

Basic configuration of spiral scale:

① Scale frame (spiral feeder) ② Weighing screw machine ③ Weighing sensor ④ Frequency converter ⑤ Weighing controller ⑥ Control cabinet

Scope of application of spiral scale:

Widely used in the measurement of powder materials or small particle materials in industries such as power, metallurgy, coal, chemical, port, building materials, ceramics, etc. Commonly measured materials include fly ash, slag powder, raw material powder, coal powder, etc. in the cement industry.
