Operate Steadily.
Deliver Consistently.
NHD Pan Vacuum Filters are widely used in alumina industry. Currently, over 260 units have been installed worldwide, with units of up to 260 m² currently operating in alumina 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.
