What is Aluminum powder laboratory test sieve?

 

Aluminum powder laboratory test sieve is a device specially used for aluminum powder particle size analysis and classification. It is widely used in the screening and quality inspection of aluminum powder in the laboratory. It can achieve efficient screening of aluminum powder through vibration or rotation to ensure the uniformity and quality of aluminum powder.

What are Aluminum powder laboratory test sieves used for?

1. Particle size analysis: Aluminum powder samples can be separated into different particle size ranges through a series of sieves with different mesh sizes. This helps determine the particle size distribution of aluminum powder, which is a key parameter for evaluating its quality and performance.

2. Quality control: Sieving can remove impurities and oversized or undersized particles from aluminum powder to ensure that the product meets specific quality standards. This is essential to ensure the consistency and reliability of aluminum powder in various applications.

3. Research and development: During the research and development of aluminum powder, sieving can be used to study the effect of particle size on material properties. This helps optimize the production process and develop new aluminum powders with specific properties.

Working principle of aluminum powder laboratory test sieve

 

Vibration screening: The aluminum powder laboratory test sieve generates excitation force through the vibration motor to make the screen box vibrate in the horizontal, vertical or three-dimensional direction. The vibration makes the aluminum powder disperse quickly on the screen surface, the fine particles pass through the screen, and the coarse particles move along the screen surface and are discharged from the discharge port.

Rotation screening: Aluminum powder laboratory test sieve makes aluminum powder move in a circular motion on the screen surface through the rotational motion, the fine particles pass through the screen, and the coarse particles move along the screen surface and are discharged from the discharge port.

What are the advantages of the aluminum powder laboratory test screen?

1. Solve the problem that aluminum powder is light and difficult to screen due to its floating property: Aluminum powder is light and has high floating force, which makes it difficult to screen effectively by traditional screening methods. Aluminum powder laboratory test screen installs low-amplitude, high-frequency ultrasonic vibration waves on the screen, which can convert electrical energy into high-frequency mechanical vibrations, so that the material on the screen surface always remains suspended.

2. Solve the problem that aluminum powder is easy to agglomerate: Aluminum powder particles are easily agglomerated due to electrostatic effects or other factors, resulting in blockage of the screen holes and incomplete screening. Appropriately reduce the feed amount and control the flow rate of the material to avoid excessive accumulation of materials on the screen and agglomeration.

 

3. Optimize the screening process: Aluminum powder laboratory test screen can also improve the screening efficiency and quality by optimizing the screening process. Reasonably design the screen area and screen hole size to improve the screening efficiency. According to the characteristics of the material and the screening requirements, reasonably control the screening speed to ensure the stability and efficiency of the screening process.

4. Solve the problem of static electricity effect: Aluminum powder is easily charged during the screening process, which may cause the material to agglomerate and agglomerate, affecting the screening effect. Aluminum powder laboratory test sieve is necessary to be grounded before the screening equipment is operated to eliminate the static electricity effect. Apply adsorbent or antistatic agent on the surface of the screen to prevent the material from being charged.

Structure of aluminum powder laboratory test sieve

 

Aluminum powder laboratory test sieve is a device used for particle size analysis and screening experiments on aluminum powder or other granular materials. This test sieve usually consists of a sieve frame, a sieve, a vibrating device, a base, a collection container, an operating panel, etc. The sieve frame is the main part of the test sieve. A sieve is installed at the bottom of the sieve frame for screening particles. Screens of different specifications can be replaced as needed.
