CJZJ intelligent management filter press is a new type of highly intelligent filtration equipment with three-stage dewatering processes: feeding, diaphragmless pressing and dry-blowing. The intelligent management system and operating monitor system achieve true unattended, reduce labor costs, and improve the scientific and technological construction of enterprises.
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.

3. Stable unloading system: filter plate single-block pulling swing technology to realize fast and complete unloading;
4. Intelligent control system: adjusting feeding, pressing and drying time intelligently to maintain the uniform quality of the product;
5. Operation monitoring system: ensuring the safe and stable operation of equipment through multiple monitoring systems of sound and image;
6. Stainless outer packing: configured with 304 or 316 stainless outer packing to ensure products are always new;
7. Filter cloth diagnostic system: rapid diagnosis of filter cloth damage to timely replacement of filter cloth and to avoid material leakage;
8. Updated technology system: independent detection and alarm of filter cloth and grout spraying.
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;
5. The intelligent management system and operating monitor system of Changjie CJ series intelligent filter press privode comprehensive guarantee for the safe, stable and high efficient operation, and promote the automation, intelligence and leanness of mining enterprises.

4. Remote service system.
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 ℃ the recommended concentration (mass ratio) is ≥ 20%.
1. A Copper Ore Plant in Zoffy, Vietnam
Filter Material: Copper concentrate
Material fineness: -200 mesh, 65%
Moisture content: ≤10%
Area per set: 66㎡
Capacity of single set: 100t/d
The Plant finally adopted the CJ series filter press to filter copper concentrate after detailed investigation on other equipment like vertical filter press, after which the water content was <10% and the filtration efficiency was up to 153kg/㎡•h.
2. A Copper-molybdenum Ore Plant in Inner Mongolia
Filter Material: Copper concentrate
Material fineness: -200 mesh, 95%
Material concentration: 50%
Moisture content: ＜12%
Area per set: 712㎡
Capacity of single set: 600t/d
The Plant adopted two kinds of equipment to process copper concentrate in the beginning: ceramic filter and tank-type pressure filter. The water content of ceramic filter was >15% which cannot meet production needs. The water content of tank-type pressure filter was 13%, accompanied with pretty high fault rate and maintenance costs, less than 40% operating rate.Then the CJ series filter press was adopted through technical improvement, after which the water content of filter cakes was changed to <12%.
