Dewatering screen in tailings dry discharge

Dewatering screen is a kind of equipment for dewatering, desliming and medium removal of slurry materials, which is widely used in various industries. So can dewatering screen be used for tailings dry discharge?
Practice has proved that the application of dewatering screen in tailings dry discharge has achieved good results. Dewatering screen is mainly used for dewatering, desliming and medium removal of tailings in dry tailings discharge, so that tailings can be discharged dry. At the same time, the useful components in tailings can be recycled. It can also effectively protect the environment.

In a copper ore mineral processing plant in eastern China, the original tailings dry discharge operation adopted the tailings dewatering process composed of thickener and filter press, which can be used normally under the condition of 95% pulp particles of -200 mesh, and the water content of the dehydrated tailings slurry is about 20%. However, with the continuous refinement of the grinding particle size in the later stage, the filter press can not complete the dewatering work well, and the service life of the filter cloth of the filter press is not long, which can last for up to 3 months. In addition, the discharge of the filter press is discontinuous, and the price is high.
Later, the concentrator of the copper mine listened to the suggestion of sinonine technical group and adopted a system composed of thickener, cyclone and dewatering screen for dry discharge of tailings. The system can meet the dewatering requirement of 80% of - 325 mesh, and the final water content of tailings slurry is about 15%. The continuous discharge of ore is realized, and the dewatering screen has no vulnerable parts and long service life, Moreover, the operation cost is reduced by about 50% compared with the filter press, which not only improves the tailings concentration efficiency, but also effectively reduces the investment of the plant.

It can be seen from the above that the dewatering screen can play a great role in the dry discharge of tailings in the concentrator.
Sinonine dewatering screen is not only used for dewatering and recovery of tailings in concentrator, but also used in ceramic materials, quartz sand washing plant, sand and stone processing plant of hydropower station, etc., which can efficiently dehydrate metal and non-metal ores. Its dewatering effect is good, processing capacity is large, screening accuracy is high, investment cost is low.
