Molybdenum powder screening solution

Molybdenum powder is an important metal powder, mainly composed of pure molybdenum elements, in the form of grayish-white fine powder. Molybdenum powder has high density, high melting point, high strength, and good electrical and thermal conductivity. Under high temperatures or specific conditions, molybdenum powder can react chemically with some elements or compounds to generate compounds or alloys with special properties. It is widely used in various fields such as food, papermaking, textiles, metallurgy, medicine, aerospace, etc.

Molybdenum powder preparation process

Step 1: Pass molybdenum trioxide with a mass purity of not less than 99.95% through a 40-mesh sieve to obtain molybdenum trioxide powder.
Step 2: Load the molybdenum trioxide powder into the material boat at a loading amount of 2.0kg/boat to 4.0kg/boat for primary reduction to obtain molybdenum dioxide.
Step 3: Load the molybdenum dioxide into the material boat again at a loading amount of 1.0kg/boat to 2.0kg/boat for secondary reduction to obtain crude molybdenum powder.
Step 4: Use a vibrating screen machine to screen the crude molybdenum powder in step 3 through a 160-200 mesh sieve to obtain the molybdenum powder under the screen.
Step 5: Mix the molybdenum powder under the screen in step 4 in a mixer and obtain the finished molybdenum powder after natural cooling.

Purpose of Molybdenum Powder Screening

Remove impurities: Remove mechanical impurities in crude molybdenum powder and improve the purity of molybdenum powder.
Particle size classification: Classify molybdenum powder according to different particle sizes.
Improve physical properties: Control the bulk density and fluidity of molybdenum powder and improve the physical properties of molybdenum powder.

Analysis of Molybdenum Powder Screening Characteristics

Adhesion: Molybdenum powder has a certain degree of adhesion and is easy to form agglomerates on the sieve, affecting the screening effect. Therefore, corresponding measures need to be taken during the screening process, such as configuring an ultrasonic device to increase the frequency and effect of vibrating screen cleaning.
