Central Transmission Thickener

Central transmission thickener is applied to mechanical discharging of small radial flow live vertical flow sedimentation sink and concentrated sink. It can further separate the free water in the sludge to reduce sludge and improve the concentration of sludge. Then, it discharges the concentrated sludge out of the sink. The structure, construction condition and the characteristic are the same as that of the mud scraper. There is a grid on the scraping arm which is beneficial to improve the sedimentation efficiency. It’s mainly used in dewatering concentrate in wet separation as the first stage of dewatering----for concentration. Generally, it’s set between the concentration and filtration device, and it’s also used to dewater before concentration sometimes. Meanwhile, it’s also applied for dewatering in chemical industry and coal concentrate plant.

The water flows radially to all sides of the overflow tank through the water drum. As water slows down, the suspended objects are separated to settle down to the bottom. The upper liquid will be discharged from the sink through the overflow weir plate. Through the reducer drive and suspension transmission, the sludge is scraped into the central tank and will be discharged by hydro-static pressure or pump.
