Necessity of dewatering vibrating screen in application of barite dehydration


Dewatering vibrating screen is a kind of slag water separation machine with low cost and high returns for mud and slurry dewatering, watering quartz sand, tailing treatment etc. It has a good effect on barite dehydration. Mud water content at about 18%-30% can reach content more than 80% on the screen after the treatment of dewatering vibrating screen, and can be dry heaped and transported after drying. Water under screen can be recycled after turbidity removal. 

Dewatering vibrating screen plays an important role in barite dehydration with low cost and high performance, and easy to install and replace. It is preference of barite manufacturers to save resources and increase revenue.

Usually the barites mining in the mountains has high mud content, can pick up the barites after washing. So dewatering is necessary. However, most of the dewatering equipment in barites concentrator is old-fashioned screw separator, which can only separate barite with large particle, and the fine particles loss with mud water causing waste of sources and income loss. Dewatering vibrating screen can reduce the loss of barites.

Concentrator should increase a dewatering screen after screw separator, and put the mud water outflow from screw separator into dewatering screen. Thus, can reduce the loss of barites through the second dressing, and the dried fine particles can be dry heaped and transported. Water under screen can be recycled after turbidity removal.
