　Product Overview

　　Screw quantitative feeder commonly known as the winch said or spiral said, is a collection of powder conveying, weighing and measuring and quantitative feeding control as a whole, electromechanical automatic control of integrated products; applicable to a variety of industrial production environment of powdery materials continuous measurement and batching control system; the use of a number of advanced technologies, reliable operation, high control accuracy; can be widely used in building materials, coal, metallurgy, electric power, chemical industry, grain, feed, glass, fertilizer, ash, sand, coke, soda ash, calcium carbonate and small lumps of coal, and other industries measuring powder or small lumps of materials process link. It can be widely used in the measurement process of powdery or small lump materials in the industries of building materials, coal powder, metallurgy, electric power, chemical industry, grain, feed, glass, chemical fertilizer, ash, sand, coke, soda ash, calcium carbonate and small lump coal. It can be divided into speed-regulating spiral scale and constant speed spiral weighing, it can be single-circuit measurement, can be used for a variety of measurement and mixed scale measurement of a variety of ways. Mainly used for powder measurement and transportation, divided into two kinds of double tube and single tube. Typical system mainly consists of steady flow feeding screw, measuring and conveying screw, frequency converter, load cell, and electric control system.

　Performance Characteristics

　　1, good sealing to adapt to strong, high reliability and long service life.
2、Flexible installation, flexible arrangement of inlet and outlet, can realize multi-point feeding and discharging, while the material also has the role of mixing and stirring, is the first choice for powder and small particles of material batching, conveying equipment.
3、More advanced technology, high precision measurement, more stable operation.
4、Feeding screw has a unique steady flow structure, in the entire cross-section of the feed port on the powder uniformly sinking, not easy to arch.
5、It can be used flexibly with other feeding equipments to realize the best automatic production process.
6、Adopting overflow feeding screw can play the functions of material locking, wind locking and flow stabilizing at the same time.
7, steady flow feeding spiral and metering spiral between the use of soft connection, not only to eliminate the steady flow feeding spiral on the metering spiral metering accuracy, but also according to the requirements of the site can be adjusted to any horizontal installation angle.
8、Measuring accuracy is better than ±1%, and the range of frequency conversion speed regulation is large.

Note: 1. The dimensions in the chart and table are based on the tube spiral LX series, for example, the center of steady material is 1800, and the center of measurement is 1500.
2. The dimensions of counter-current spiral LXN series and double-tube LXS series refer to LX series.
3. The value of conveying capacity is a reference value, when the speed ratio of reducer and pitch S, and material filling coefficient are changed, the conveying capacity will be changed accordingly.
