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.

Vibrating screens can be applied in many industries, such as mining, construction, chemical, pharmaceutical, food processing, etc. The following are some common applications of vibrating screens:

1. Mining: Vibrating screens can be used to screen materials such as ore, coal, limestone, etc. to ensure the quality and purity of the materials
2. Architecture: The vibrating screen can be used to screen building materials such as concrete, sand, and stones to ensure the quality and uniformity of the materials.
3. Chemical industry: Vibrating screens can be used to screen chemicals, coatings, paints, pigments, and other materials to ensure the quality and purity of the materials.
4. Pharmaceutical: The vibrating screen can be used to screen materials such as drugs, vaccines, and syrups to ensure the quality and purity of drugs.
5. Food processing: The vibrating screen can be used to screen materials such as flour, sugar, starch, and milk powder to ensure the quality and uniformity of the materials.

The impurities mixed in mung beans are generally stones, dust, weeds, etc. If you want to get rid of these impurities, a linear vibrating screen is the first choice for removing these impurities. The main reasons for choosing a linear vibrating screen are the following:

1. The linear vibrating screen has a large output and high efficiency. Generally, the output of the linear vibrating screen can be between 1 and 10 tons per hour. Compared with the rotary vibrating screen, the large output of the linear vibrating screen is more suitable for the needs of manufacturers.
2. The linear vibrating screen has a simple structure and is easy to maintain. For the equipment with simple structure for the production line, if there is a problem, it can be repaired in time, and the fault is checked.
3. The full-closed structure of the linear vibrating screen, the dust will not fly, because there are dust and other impurities in the mung bean, the full-closed structure can prevent the dust from flying in the workshop and protect the clean environment of the workshop.

For screw conveyors used in metallurgy, mining and chemical industries, the shaft end gland is widely sealed with packing. Because the particle size of the coal powder is 200 mesh, it is in the form of fine powder and has a certain fluidity, so it is often because the shaft end of the screw conveyor head is not tightly sealed and many coal powders are leaked. Although asbestos packing, oil-impregnated asbestos rope and flexible graphite ring are also used as sealing packing, the leakage control effect is not ideal. Pulverized coal leaks around the equipment every day, which wastes and pollutes the environment and affects civilized production. In order to solve this problem, the following method hopes to be useful to you.
1.Lubricating grease must be added into the gland every 3-4 days, otherwise the coal powder will still be leaked or the coal powder will leak out
2.After each installation and disassembly, the gland bolts must be tightened for about one month after starting up, so that the packing and the shaft closely fit together. But it is not necessary to press too tightly, the gland bolts can be adjusted according to the actual situation.
