Rotary vibrating sieve for screening powder materials

Rotary vibrating sieve is a commonly used screening equipment, which can be widely used in the screening of powder materials in chemical industry, metallurgy, building materials, ores, pharmaceuticals and other industries. The rotary vibrating sieve has the characteristics of simple structure, convenient operation, and large processing capacity, and can efficiently complete the screening of powder materials.

Working principle of rotary vibrating sieve for screening powder materials:

The screening principle of the rotary vibrating sieve is to make the powder material move relative to the screen surface through the vibration force, so as to realize the separation of the powder material. When the rotary vibrating sieve is sieving, the powder is evenly distributed on the sieve surface, and then due to the action of the vibration force, the material moves in a spiral shape, and finally the powder materials with different particle sizes are separated through the sieve holes. Larger particles are blocked on the sieve surface by the sieve holes, while smaller particles fall through the sieve holes to the lower layer. By adjusting the vibration parameters of the rotary vibrating screen, the screening of different powder materials can be realized.

The rotary vibrating sieve has the following characteristics and advantages in screening powder materials:

1. High efficiency: Adopting advanced design and vibrating sieve technology, it can quickly separate particles of required size. High screening efficiency can greatly improve production efficiency.

2. High accuracy: The rotary vibrating sieve is equipped with multi-layer screens, which can continuously separate materials with multiple particle sizes. The screen size and sieving levels can be adjusted as needed to achieve the desired precise sieving effect.

3. Strong adaptability: suitable for screening of various powdery materials, such as ores, chemical raw materials, food additives, etc. It can handle materials with a wide range of particle sizes, and has good adaptability to materials with special properties such as humidity, viscosity, and adhesion.

4. Simple structure and easy maintenance: the structure of the rotary vibrating sieve is relatively simple, easy to clean and maintain. Vulnerable parts such as vibrators and damping springs are also easier to replace and repair, prolonging the service life of the equipment.

5. Energy saving and environmental protection: The rotary vibrating sieve adopts vibration energy transmission during work, which can reduce energy consumption and noise generation compared with other screening equipment. At the same time, because the dust is less spilled, it is more in line with environmental protection requirements.

When using a rotary vibrating sieve for screening powder materials, there are several precautions:

1. Selection of sieve hole: The size of the sieve hole determines the particle size distribution of the material. The smaller the sieve hole, the smaller the particles that can be screened out. Therefore, when selecting the sieve hole, it is necessary to make a reasonable choice according to the particle size requirements of the material.

2. Material feeding method: In order to ensure that the material can be evenly distributed on the screen surface, the feeding should be uniform and continuous, and not excessive, so as not to cause the screen to be blocked.

3. Control of screening time: Too long screening time will cause materials to accumulate on the screen surface, affecting the screening effect; too short screening time may result in incomplete screening. Therefore, we need to reasonably control the screening time according to the characteristics of the material and the screening requirements.

4. Clean the screen: the screen is easily blocked by the deposition of materials, which affects the screening effect. Therefore, during the screening process, cleaning the screen in time to keep the screen holes unobstructed can effectively improve the screening efficiency.

In short, the rotary vibrating sieve has the advantages of high efficiency, high accuracy, strong adaptability, simple structure and easy maintenance in sieving powder materials. The rotary vibrating sieve plays an important role in the screening of powder materials. Reasonable operation and maintenance of rotary vibrating sieve can improve screening efficiency and ensure the quality of materials.
