The Maintenance and Use of Vibrating Screen Mineral Processing
1. Check the anchor bolts. In the precautions for the use of vibrating screen, we need to carefully check the anchor bolts. This position is easy to loosen, once it is loose, it will produce great vibration and noise, even burn down the motor, which will cause great damage to the equipment. 2. Check the screen.Niobium and tantalum are mainly produced from columbite–tantalite ores, and 60% of their production is nowadays located in the Democratic Republic of Congo and Rwanda.
