Parameters

Structural composition

• Casing: 

As the main supporting structure of the equipment, it plays a role in protecting the internal components. It is generally made of strong materials such as steel to ensure good sealing and prevent powder leakage.

• Feeding device: 

It is used to transport the material to be classified into the Powder Classifier. It is usually designed to allow the material to enter evenly to ensure the stability of subsequent classification.

• Rotor: 

It is the core component, on which blades or fins of special shapes are installed. The high-speed rotation of the rotor generates centrifugal force and vortex, so that the material can be classified in it.

• Drive device:

 It provides power to the rotor to rotate at a specific speed. It is usually composed of a motor, a reducer, a coupling, etc.

• Air outlet: 

It discharges the airflow carrying fine powder so that the fine powder can be collected later.

• Coarse powder outlet: 

It is used to discharge coarse powder that does not meet the fineness requirements after classification.

• Working principle: 

After the material enters the powder classifier from the feeding device, it falls under the action of gravity. At the same time, the air or gas from the outside enters the powder classifier. The rotor rotates at high speed driven by the driving device, generating a strong vortex. The material is dispersed under the action of the vortex. Due to its small mass, the fine powder can follow the airflow through the gap inside the rotor or a specific channel and be discharged from the air outlet; while the coarse powder is subjected to a large centrifugal force due to its large mass, and cannot pass through the relevant channels, and is finally discharged from the coarse powder outlet, thereby achieving material classification.

Advantages and characteristics

High classification efficiency:

• Multiple classifications: 

Through the unique structural design, the material can undergo multiple classification processes in the powder classifier, which improves the accuracy and efficiency of classification. For example, some high-efficiency ultra-fine rotor powder classifiers are equipped with multi-stage rotors or special classification areas, which can SCReen the materials more carefully.

• Good dispersion effect: 

The high-speed rotation of the rotor and the special spreading device can fully disperse the material in the airflow, increase the separation effect of fine powder and coarse powder, and thus improve the powder selection efficiency.

• Flexible fineness adjustment: 

The fineness of the product can be easily changed by adjusting the rotor speed, air volume and other parameters to meet different production needs. And this adjustment has high sensitivity and reliability, and can quickly and accurately achieve fineness control during the production process.

• Large processing capacity: 

The equipment has a reasonable structural design and can meet the needs of large-scale production. It has a large feed volume and processing capacity, and can meet the high-output requirements of the production line.

Low energy consumption:

• Optimized structural design: 

The flow path of the airflow in the powder classifier has been optimized, which reduces the resistance of the airflow and the energy consumption of the fan. At the same time, the design of the rotor can also reduce the energy consumption of the drive device while ensuring the classification effect.

• Efficient energy utilization: 

Some high-efficiency ultra-fine rotor powder classifiers adopt the design of internal circulation wind, which can make full use of the energy of the airflow, reduce the amount of external air introduced, and further reduce energy consumption.

• Wide range of application: 

It can be applied to the classification of various materials, such as cement, ore, coal powder, chemical raw materials and other powder materials, and has good adaptability to materials with different particle size distributions and physical properties.

Easy maintenance:

• High wear resistance of vulnerable parts: 

Wear-resistant linings or parts made of wear-resistant materials are usually installed in wear-prone parts, which improves the wear resistance of the equipment and reduces the frequency and cost of maintenance.

• Easy structure maintenance: 

The structural design of some equipment is easy to disassemble and install, which can save time and labor costs when maintenance or replacement of parts is required.
