Parameters

Structural composition

• Casing: 

As the main structure of the equipment, it plays the role of supporting and protecting the internal components. It is usually made of solid metal materials and has good sealing to prevent powder leakage.

• Feeding device: 

It is used to evenly transport the materials to be classified into the Powder Classifier to ensure that the materials can stably enter the classification area.

• Rotor: 

It is the core component of the powder classifier. It is usually equipped with blades or fins of special shapes. The rotor rotates at high speed driven by the drive device to generate eddy currents.

• Drive device: 

It provides power to the rotor so that it can rotate at a certain speed. The drive device is usually composed of a motor, a reducer, a coupling, etc.

• Air outlet: 

It is used to discharge the airflow carrying fine powder, and the fine powder is collected by the subsequent dust collection device.

• Coarse powder outlet: 

It is located at the bottom of the equipment or other suitable positions, and 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 outside air or gas enters the powder classifier through a specific air inlet. The rotor rotates at high speed driven by the drive device, generating a strong vortex. The material is dispersed under the action of the vortex and moves in the air flow according to its own particle size, density and other characteristics. Due to its small mass, the fine powder can follow the air flow through the gap inside the rotor 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 rotor gap, and is finally discharged from the coarse powder outlet, thus achieving the classification of the material.

Advantages and characteristics

High classification efficiency:

The use of advanced classification principles and optimized structural design can accurately classify the material, so that the fine powder and coarse powder can be effectively separated. For example, its unique rotor structure and air flow field design make the material dispersion effect in the powder classifier better and the classification accuracy higher.

For materials with a wide particle size distribution, a good classification effect can also be achieved, and the powder selection efficiency can usually reach more than 85%, or even higher.

Large processing capacity:

The structural design of the equipment is reasonable and can meet the needs of large-scale production. It has a large feed and discharge port, as well as a spacious grading space, which can ensure the smooth passage of materials.

Under the premise of ensuring grading efficiency, it can handle a large amount of materials, and the single machine has strong processing capacity, which can effectively improve production efficiency.

Low energy consumption:

The equipment is optimized and designed using aerodynamic analysis methods. The resistance of the equipment is small, and the airflow in the powder classifier flows more smoothly, reducing the energy consumption of the fan.

The rotor drive device adopts a high-efficiency motor and reducer, which can achieve high-speed rotation at a lower power, further reducing energy consumption.

Easy to operate:

The equipment has a high degree of automation and is equipped with an advanced control system, which can realize remote operation and monitoring, making it convenient for operators to grasp and adjust the operating status of the equipment in real time.

The fineness adjustment is convenient. By adjusting the rotor speed, air intake and other parameters, the fineness of the product can be quickly changed to meet different production needs.

Strong adaptability:

It can adapt to the grading of various types of materials, including cement, ore, coal powder and other powder materials, and has a wide range of applications.

It also has good adaptability to materials with different humidity and temperature, and can maintain stable operating performance under harsh working conditions.

Low maintenance cost:

The equipment has a simple structure, a small number of parts, and the wearing parts are made of wear-resistant materials or have undergone special surface treatment, which has high wear resistance and corrosion resistance, reducing the maintenance and replacement frequency of the equipment.

The daily maintenance work is relatively simple. Regular inspection, cleaning, lubrication and other routine maintenance are required to ensure the normal operation of the equipment and reduce maintenance costs.
