Operate Steadily.
Deliver Consistently.
NHD Rotary Table Vacuum Filters are widely used in the industry of phosphoric acid. Currently, over 300 units have been installed worldwide, with units of up to 320m² currently operating in phosphoric acid applications.
These filters have also been progressively adopted in other sectors including metallurgy, environmental protection, ore washing, and paper manufacturing.
Water-saving nozzles
deliver low energy consumption and high flushing power, working synergistically with anti-clogging filter elements.
Low distribution valve
minimizes scaling and clogging, reducing cleaning frequency
Segmented filter discs
ensure smooth operation and strict flatness control
Plate-type distributor
ensures uniform slurry distribution for better cake drying and washing efficiency
Air suction hood
reduces gas leakage, facilitates tail gas collection, and improves working environment
Grid-supported frame
features low-density high-strength construction, minimizing shadowing and bridging effects while preventing pan scaling.
