The production process of molybdenum powder is a complex physical and chemical process. Most industries choose the process method starting from ammonium molybdate and undergoing thermal decomposition and hydrogen reduction. The specific process includes the roasting-stage reduction method; the ammonium molybdate two-stage reduction method . There are two types of reduction equipment: fixed bed type and fluid bed type.

The various processes are as follows:
1. Baking-segmented reduction method:
Ammonium molybdate → roasting → molybdenum trioxide → screening → primary reduction → molybdenum dioxide → screening → secondary reduction → molybdenum powder → screening → batching

2. Two-stage reduction method of ammonium molybdate:
Ammonium molybdate → primary reduction → molybdenum dioxide → screening → secondary reduction → molybdenum powder → screening → batching

The molybdenum powder produced by any process must meet the production needs of different powder metallurgy products. The quality of molybdenum powder is mainly measured on the basis of chemical purity and physical properties. The main content of physical properties is particle size and bulk density (fluidity). Therefore, the vibrating screen is irreplaceable in the molybdenum powder production process.

Linear vibrating screen
Linear vibrating screen manufacturer - machine introduction
DZSF series linear vibrating screen uses the vibration motor installed at the bottom of it as vibration source. When working, the two motors spin in opposite directions, the eccentric blocks at the ends of motor produce vibration force. Under the action of vibration force, the screen box which supported on the four compression spring produces a continuous linear vibration. In the process of the movement, the materials do the projectile motion and keep going in a straight line at the same time. The materials enter into the feed port, go through the multi-layer screen, then different size of materials was separated out from different outlet.
