Filter Presses

Modern mining requires efficient, cost-effective and environmentally friendly technologies for fine solids dewatering. A filter press, schematically shown below, utilizes the pressure difference provided by the feed pump and pressurized media to achieve solid-liquid separation and has been gaining popularity in the mining industry for both tailings as well as ore concentrate fines dewatering. DADI, through its regional operations, provides the award-winning Jingjin filter press manufactured by Jingjin Environmental Protection, Co. Ltd, a world-wide authority in industrial filtration technologies.

High Efficiency Press

High Efficiency Membrane Filter Press

With decades of technical advancement and innovation, the high-efficiency membrane filter press has been widely used in coal preparation, mineral processing and titanium dioxide manufacturing. It is known as a workhorse filter press that delivers consistent throughput, excellent availability and stable performance.

•    High efficiency, 3-4 cycles per hour.
•    Quick feeding by simultaneous feeding from both ends.
•    Improved dewatering performance using single chamber feeding plates. For example, < 8% cake moisture can be achieved on copper and gold concentrate filtration. 
•    Multiple sizes available including 1000, 1250, 1500, 1600, 2000 and 2500×2600 models (numbers referring to plate size in mm).
•    High throughput, up to 1,500 m2 filtration area on a single unit.

Single Chamber Press

Single Chamber Feeding with Air Drying Filter Press

In a single chamber feeding with air drying filter press, slurry is fed into each filtration chamber independently, resulting in a more uniform cake formation. Instead of squeezing the cake by the membrane plate, compressed air is directly introduced to the filtration chamber in this type of filter presses. While the compressed air penetrates the cake, more liquid can be removed without further compressing the cake. Thanks to the unique design, this filter press can produce a low moisture and loosely structured cake, which is preferred in many dewatering applications.

  • Excellent sealing and easy filter cloth replacement.

  • Low cake moisture, e.g., <7% cake moisture on iron ore and gold concentrate and <13% moisture on clean coal can be achieved; Cake moisture usually 8-15% less than competing filter presses on the market, depending on specific applications.

  • Efficient cloth washing using 30-50% less water.

  • High filtration area, 13% higher than conventional plates.

  • Fully automatic and high efficiency with 4-5 cycles per hour. Optional automatic cake dischargers available.

Ultra-High Pressure Membrane Filter Press

To increase the operating pressure, all major components of the filter press, including membrane plates, hydraulic unit and main frame body have been carefully engineered and fabricated to make the ultra high pressure press. At the membrane pressing stage, pressurized water is pumped into the membrane plates and the working pressure can reach 100 bars, whereas the conventional membrane filter press using compressed air normally operates from 7 to 12 bars. Thanks to the ultra-high working pressure, this type of filter presses has been widely used for ultrafine particles and tailings dewatering in many industries.

  • Ultra-high and adjustable working pressure (10 to 100 bar).

  • High feed pressure, up to 40 bar.

  • Self-locking hydraulic cylinders for maximum safety and energy saving.

  • Low cake moisture, 20-30% lower than conventional presses. For example, 17-18% cake moisture on titanium oxide yellow pigment (80 bar), 13-16% on coal flotation tailings (55 bar) can be achieved.
