Application of rotary vibrating screen in chemical industry
Application of Large-scale Rotary Vibrating Sieve in Chemical Industry

Rotary vibrating screen is a commonly used screening equipment, which is widely used in material screening, classification, removal of impurities and other processes in the chemical industry. Here are a few applications of rotary vibrating screens in the chemical industry:

Classification and screening: rotary vibrating screen can be used for classification and screening of chemical raw materials, intermediates and products. For example, for the screening of polymer particles, screens with different apertures can be used according to the particle size to separate particles of different particle sizes to meet the needs of different particle sizes. In addition, for the classification and screening of granular materials such as catalysts, adsorbents, and activated carbon, rotary vibrating screens are also commonly used equipment.

Removal of impurities: There are often impurities in raw materials, intermediates and products in the chemical industry, such as metal particles, fibers, particles, etc. These impurities will affect the quality of materials and process efficiency. The rotary vibrating screen can be used to remove these impurities to ensure the quality of the material. For example, for metal particles in granular materials, a combination of magnetic screening and rotary vibrating screen can be used to remove metal particles to achieve the purpose of purifying materials.

Recycling: In the chemical industry, some materials can be recycled through rotary vibrating screens. For example, for materials such as waste polymers and waste liquids, they can be classified, screened, and dried through rotary vibrating sieves to recycle useful materials and reduce waste rates and waste of resources.

In short, the rotary vibrating screen has a wide range of applications in the chemical industry, and is often used in material screening, classification, removal of impurities, recycling and other processes. When using a rotary vibrating screen, it is necessary to select appropriate parameters such as screen aperture, amplitude and vibration frequency according to the material properties and screening requirements to ensure the best screening effect and productivity.

Rotary vibrating screen is a commonly used screening equipment, which is widely used in materials screening, grading, removing impurities and other processes in the construction industry. Here are a few applications of rotary vibrating screens in the construction industry:

Sand screening: The sand and gravel materials commonly used in the construction industry need to be screened to meet the needs of different particle sizes. The rotary vibrating screen can be used to screen and classify sand and gravel materials to separate sand and gravel particles that meet the requirements. At the same time, the rotary vibrating screen can also remove impurities in the gravel and improve the quality of the gravel.

Cement production: The rotary vibrating screen can be used for material screening in cement production. For example, in the production process of cement raw materials, limestone, clay and other materials need to be screened to separate the material particles that meet the requirements and ensure the quality of cement.

Concrete Production: In the process of concrete production, the aggregate needs to be screened to meet the strength and quality requirements of the concrete. The rotary vibrating screen can be used for sieving and grading the aggregate to separate the aggregate particles that meet the requirements and remove impurities and dust.

Construction waste treatment: Construction waste often contains useful bricks, steel bars and other materials, which can be separated and recycled by rotary vibrating screens. The rotary vibrating screen can be used to screen, classify, remove impurities and other processes for construction waste, reduce waste disposal costs and improve resource utilization.

In short, the rotary vibrating screen has a wide range of applications in the construction industry, and is often used in sand and gravel screening, cement production, concrete production, construction waste treatment and other processes. When using a rotary vibrating screen, it is necessary to select appropriate parameters such as screen aperture, amplitude and vibration frequency according to the material properties and screening requirements to ensure the best screening effect and productivity.

Rotary vibrating screen is a commonly used screening equipment, which can separate granular materials according to particle size. Aluminum powder is a common metal powder that can be sieved through a rotary vibrating sieve.

The working principle of the rotary vibrating screen is to make the granular material roll, jump and collide in the screen hole under the action of gravity through the vibrating screen, so as to realize the screening of the material. For fine particles such as aluminum powder, it is necessary to use a sieve with a smaller sieve size for sieving to ensure the separation effect.

During the sieving process, attention needs to be paid to controlling the sieving time and amplitude to avoid particle breakage and loss caused by excessive vibration and excessive sieving time. In addition, it is necessary to keep the screen clean and clean the particles blocked by the screen in time to ensure the screening efficiency and accuracy.

In short, the use of rotary vibrating sieves for aluminum powder sieving requires the selection of appropriate sieves and control of sieving conditions to obtain a good separation effect.

The size of the screen suitable for screening aluminum powder varies with different application scenarios and screening requirements. Generally speaking, the pore size of the screen should be smaller than the average particle size of the aluminum powder to ensure the screening effect.

The following are some commonly used sieve sizes suitable for sieving aluminum powder, for reference only:

A mesh with a sieve aperture of 20 mesh or smaller can be used to separate finer aluminum powder, and is usually suitable for the process of preparing high-precision metal powder;
A sieve with a mesh size of 40 mesh or smaller can be used to separate medium-sized aluminum powder, and is usually suitable for the process of preparing high-strength alloys;
A sieve with a mesh size of 80 mesh or smaller can be used to separate coarser aluminum powder and is generally suitable for the process of making conventional metal products.
It should be noted that if the pore size of the screen is too small, the sieve hole will be blocked and affect the screening effect; if the pore size of the screen is too large, the screening accuracy will be affected. Therefore, the selection of an appropriate screen size needs to take into account the specific screening requirements and the physical characteristics of the aluminum powder

Usage of vibrating screen
1. Installation of vibrating screen: Firstly, it is necessary to ensure that the installation position of the vibrating screen meets production requirements and determine the installation method based on on-site conditions. Generally speaking, the vibrating screen can be installed above the silo, below the storage tank, or other appropriate positions.
2. Adjusting the amplitude and frequency of the vibrating screen: Before using the vibrating screen, it is necessary to adjust the amplitude and frequency of the vibrating screen to ensure the screening effect and production efficiency of the materials. The amplitude can usually be adjusted by changing the size of the screen, while the frequency can be adjusted by changing the speed of the motor.
3. Start the vibrating screen: Before starting the vibrating screen, it is necessary to ensure that the motor and reducer have been installed correctly, and check whether the connection between the screen and the motor is secure. Next, you can press the switch to start the motor and observe the operation of the vibrating screen.
4. Adjusting the amplitude and frequency of the vibrating screen: When using the vibrating screen, it is necessary to adjust the amplitude and frequency in a timely manner based on the characteristics of the material and production needs. Generally speaking, the finer the particles of the material, the smaller the amplitude and the higher the frequency.
5. Cleaning the vibrating screen: After using the vibrating screen, it is necessary to clean the screen and reducer in a timely manner to ensure the normal operation of the equipment and production safety. Water or cleaning agents can be used for cleaning, but corrosive chemicals must not be used.
