CJZH high-efficiency automatic filter press is a new type of intelligent filtration equipment with three-stage dewatering processes: feeding, diaphragmless pressing and dry-blowing. It is upgraded with intelligent control system based on CJAH high-efficiency automatic filter press. CJAH can automatically adjust the pressing time and record the capacity and other parameters, reducing operating cost of the enterprise and manual participation.
1. The feed filtration is based on the delivery pressure of the slurry pump, so that the slag entering the filter chamber is trapped by the filter cloth to form a filter cake; the water is filtered through the filter cloth to achieve solid-liquid separation;
2. Press filtration is to press on the side of the porous filter cake formed by the feed filtration, shrinking the voids and eliminating the water in the voids;
3. Dry-blowing filtration uses high-speed compressed air to pass through the cake and remove intermittent water, further reducing the moisture content of the cake.
Regardless of how much pressure is used to press the filter cake, the gap between the material particles cannot be completely eliminated. Therefore, the dry-blowing filtration, using high-pressure air to pass through the cake and remove moisture from the particles gap , is the important means to reduce the moisture content of the filter cake. However, effective prevention of short-circuit of compressed air during drying is the key to effective drying. Dry-blowing filtration is the unique design of the CJAH Series high-efficiency filter press. Other filters press cannot achieve filter cake to be blown dry effectively without dry-blowing filtration technology.

1. Filter cloth diagnostic system: realize rapid diagnosis of filter cloth breakage, replace filter cloth in time to avoid material leakage;
2. Outsourcing of equipment surface: The surface of the equipment can be covered with a variety of corrosion-resistant materials.
1. High performance: Filtered iron concentrate cake can achieve moisture content <6%, Under the same material and filter conditions, the filter cake moisture content can be 5-8 % lower than that of box filter press, box diaphragm filter press and frame filter press;
2. High capacity: single daily processing capacity is larger, the production capacity of same filter area is much larger than that of the box diaphragm filter;
3. High intelligence: Intelligently adjust the filtering parameters such as feed time, press time, filtration pressure, etc.; Automatically record important parameters such as cake weight, moisture content, air pressure, voltage, current, motor speed, hydraulic pressure, working temperature, etc.; automatic filter cloth regeneration; automatic detection of faults; unattended;
4. High adaptability: The equipment has been applied under different conditions of over 5,000m altitude, different material concentrations and different grinding granularity, and the moisture content of filter cake can achieve the lowest in the industry.
1. The equipment is suitable for mining, metallurgy, chemistry, food, pharmaceutical industry and environmental protection fields;
2. When used in materials which is relatively difficult to filter and form cakes, maximize performance benefits, achieve lower moisture content, and improve customer filtration quality;
3. Operating environment temperature is 5-90 °C, the recommended concentration (mass ratio) is ≥ 20%.
1. A Copper Company in Yunnan
Filter material: copper concentrate
Material fineness: -400 mesh, 90%
Feeding concentration: 50%
Moisture content: 10%
Filtration area per set: 328 ㎡
Daily capacity per set: 600t/d
The plant originally adopted a well-known diaphragm filter press in China, but the moisture content was high and needed a lot of manual assistance. The daily capacity per set was only 180 t/d. The plant turned to use CJ series filter press after several rounds of on-site inspections and trial demonstrations, and then the moisture content reduced to below 10% and daily capacity per set is over 600 t/d.
2. A Mining Mompany in Sichuan
Filter material: gold concentrate
Material fineness: -200 mesh, 70%
Feeding concentration: 40%
Moisture content: 8%
Area per set: 100 ㎡
Daily capacity per set: 110t/d
The plant successively purchases CJ series filter press to process gold concentrate. The economic and technological needs of the enterprise are fully satisfied by reducing the moisture content to 8%.
3. A Mining Company in Tibet
Filter material: copper-molybdenum mixed concentrate
Material fineness: -325 mesh, 90%
Feeding concentration: 40%/60%
Moisture content: 10%/12%
Area per set: 648 ㎡
Daily capacity per set: 750/700t/d
The plant originally adopted ceramic filter to process copper-molybdenum mixed gold mine, the moisture content was as high as 18-20%, ceramic plate capillary pores are frequently blocked, and pickling costs are high. CJ series filter press was adopt after 2017 technical transformation, the moisture content is about 10% now.
4. A Copper Mine in Qinghai
Filter material: copper, lead, zinc concentrate
Material fineness: -320 mesh, 90%
Feeding concentration: 40-50%
Moisture content: 8%/11%/10%
Area per set: 255/60/80 ㎡
Daily capacity per set: 300/80/100 t/d
The plant originally adopted vacuum ceramic filter to process copper lead and zinc concentrate, the moisture content of filtercake was high and unable to use car transport, led to product sales difficulties. CJ series filter press was adopt after technical transformation, the average moisture cotent of filtercake is 10%, and sales problems are solved.
5. A Phosphorus Chemical Company in Hubei
Filter material: phosphorus tailings/ phosphate ore/ phosphate concentrate
Material fineness: -200 mesh, 82%/ -200 mesh, 80%/ -400 mesh, 70%
Feeding concentration: 50%-60%/ 50%/ 45%
Moisture content: 9%/ 12%/ 10%

单台产能：650 /600/500 t/d
Daily capacity per set: 650/ 600 /500 t/d
The plant originally adopted ceramic filter to process phosphorus tailings, the moisture content of fitercake was over 20% and unable to stack. Five sets of 120m2 ceramic filter had a daily output of less than 250 tons. Later, the plant adopt 5 sets of CJZH high-efficiency automatic filter press.The moisture content of filtercake is 9% and daily capacity per set is 700 t/d now. Meanwhile, filter cloth regeneration effect is remarkable and its service life is greatly extended, and the calcium content of the filter cloth is extended from 7-15 days to 60 days.
