Star feeder, also known as rotary feed valve, star discharger, etc., is a commonly used material conveying and feeding equipment.
The star feeder is mainly composed of a housing, a rotor, and a drive device. The housing is usually cylindrical, with a rotor installed inside. There are multiple blades or compartments evenly distributed on the rotor, and the shape is similar to a star, hence the name. The drive device is generally a motor and a reducer to provide power for the rotation of the rotor.
Its working principle is: when the motor drives the rotor to rotate, the material falls into the compartment of the rotor from the upper feed port. As the rotor rotates, the material is carried by each compartment and transported to the discharge port below. By controlling the speed of the rotor, the feeding amount of the material can be adjusted.
Star feeder has the following features:
1. Good sealing
It can effectively prevent material leakage and external air from entering, and is particularly suitable for pneumatic conveying systems that require high sealing performance. It can maintain good sealing performance under positive or negative pressure working conditions to ensure stable operation of the system.
2. Dosing
The feeding amount of materials can be controlled more accurately to meet the needs of different production processes. By adjusting the speed of the rotor, the feeding amount can be precisely adjusted.
3. Strong adaptability
It is suitable for conveying various powdery, granular and small block materials, such as coal powder, cement, grain, chemical raw materials, etc. At the same time, it can adapt to different working temperature and pressure ranges and has strong versatility.
4. Compact structure
Small size, light weight, small space occupation and easy installation. It can be connected with various upstream and downstream equipment to form a complete material conveying system.
5. Reliable operation
It has high reliability and stability, and low failure rate. The gap between the rotor and the housing is small, which can reduce material blockage and wear and extend the service life of the equipment.
In industrial production, star feeders are widely used in cement, chemical, metallurgy, electric power, grain and other industries for quantitative feeding, unloading and air locking of materials, providing strong support for the automation and efficiency of the production process.
