The fluidity, particle morphology and particle size distribution composition of molybdenum powder have obvious effects on the screening efficiency when using a large-mesh vibrating screen. Effective area, material of screen surface and screen size. The shape of the screen hole of the vibrating screen is also one of the factors that determine the screen penetration rate. The particle size of the under-sieves sieved by the circular sieve is smaller, while the effective sieve surface of the rectangular sieve is large, the quality of the sieve surface is light, and the production capacity is large. Molybdenum powder particle size of shaped and square meshes.

The reasonable selection of the vibration motor is the key factor affecting the screening effect of the vibrating screen. Generally speaking, larger amplitude and lower vibration frequency are used for molybdenum powder with larger particle size; smaller amplitude and higher vibration frequency are used for molybdenum powder with smaller particle size. In addition, the uniformity of feeding has a great influence on the screening process of molybdenum powder. If the feeding is too much, it will increase the load on the screen surface of the vibrating screen, reduce the screening efficiency, and accelerate the frequency of screen breakage.
