04/03/2022· The tailings dewatering screen is often used in the dehydration of metal tailings, the dehydration link of the ceramic raw material processing system, the tailings extraction treatment of the beneficiation plant, the processing system of quartz sand, the processing system of sand and gravel in hydropower stations, etc. The tailings dewatering screen can also be
The process water bound by the tailings remains unused. With modern dewatering solutions, mining residues can be treated economically and the process water that they contain can be recovered. This saves both space and cost and is environmentally friendly. In mining, the term tailings refers to fine grained residues in the form of sludges.

a dewatering screen that directly receives the coarse fraction obtained during the first classification stage, produces a final cake with the enough concentration to allow its transportation through conveyor belts to the tailings deposit area . Pulp being filtered by the screen is pumped towards a cyclones battery cluster,
For dewatering of slurries with fine PSD, high G forces are required. The ANDRITZ decanter centrifuge A10 4 operates with high speed design capabilities for tailings and fine solids dewatering. Due to its large diameter to length ratio, it allows you to handle high volumes and increase recovery rates.
When the feed to the vibrating screen was reduced to 1.5 tph/ft to achieve equilibrium dewatering conditions , only 15 percent of the coal finer than 28 mesh was recovered in the screen oversize , When the scalping deck was added to the vibrating screen and the feed rate increased to 8 tph/ft, the recovery of material finer
The ® DW dewatering screen range has an innovative curved, sieve bend like feed section. This curved profile increases the screening area and the dewatering capacities, using centrifugal force to aid in the dewatering process. The main deck of the screen slopes upwards to maximise solids retention and dewater the cake bed.
The vibration dewatering screen is a newly developed tailings disposal technology. After the tailings are concentrated and dehydrated, not only save the construction cost and conventional maintenance cost, but also make good use of the wastewater, which the occupied space can be greatly saved, and the potential dangers of the tailings pond can ...
LDHB tailings dewatering screen has a good effect on tailings treatment. Generally, the tailings slurry with 18% 30% concentration can be treated with dewatering screens to achieve solid content of more than 85%, even some coarse sand tails can reach more than 90%, and reach the dry heap. The water under the screens can also be recycling.
