Compared with the traditional spiral dehydration equipment, the discharge concentration is about 60 percent, the dehydration rate is 55.56 percent, and the dehydration rate of the invention is improved by 32.68 percent.
Because the discharge concentration of the vacuum spiral dehydration equipment is high, the water content is low, the area of a traditional natural dehydration area can be reduced, and the civil engineering investment is low.
Application example 2
Aiming at quartz sand in the places of Guangdong, flotation concentrate is fed into the efficient vacuum spiral dehydration and chemical removal equipment after flotation operation, the feed concentration is 40%, the discharge concentration is 80%, and the dehydration rate is 83.33%.
