Customer Case: The XAZ6/450-30 fully automatic box-type filter press helps a South American mining client solve the problem of dehydration.
Case Background
A medium-sized copper mining enterprise in northern Chile has been struggling with the problem of low tailings dehydration efficiency for many years. The mine processes approximately 200 tons of copper ore daily, generating a large amount of highly fine mineral slurry with a high moisture content. The original old plate and frame filter press was manually operated, and the processes such as pressing the filter plates, discharging the cake, and cleaning the filter cloth all required frequent manual intervention. The single batch filtration cycle lasted for more than 90 minutes, severely restricting the progress of downstream material processing, and due to the high moisture content of the filter cake, the transportation cost remained high.
After conducting extensive online research and comparing various equipment, the manager of this mine processing plant contacted our engineering team, expressing the desire to seek a fully automated solution that can handle large volumes of mineral slurries, while minimizing manual operations and reducing the final moisture content of the filter cake to the greatest extent possible.
Solution
After communication, our technical team recommended the XAZ6/450-30 fully automatic box-type filter press, and customized the parameters according to the actual working conditions.
The specific configuration includes:
- Carbon steel heavy-duty frame, with surface anti-corrosion coating treatment
- Automatic hydraulic pressing system, with adjustable pressure
- Center hole feeding to ensure uniform distribution of the slurry in each filter chamber
- Dual dark liquid discharge method, with the filtrate being centrally discharged, and there is no spillage at the site.
- Once the filter plate mechanism is opened, all the filter plates separate simultaneously.
- Automatic discharge system, minimizing the need for human intervention
- Integrated automatic blowing function. Before removing the filter plate, it will blow away the remaining filtrate.
- A 304 stainless steel receiving hopper is placed below the filter plate, facilitating the centralized collection of the filter cake.

Operation Results
After a continuous operation period of three months, the customers provided the following quantifiable improvement achievements:
The fully automated process takes approximately 35 minutes per batch, reduced by 60% compared to manual equipment. Daily filtration batches increased from 12 to over 30 batches.
The integrated automatic blowing function controls the filter cake moisture content stably below 18% (previously 25%-28%), significantly reducing transportation costs.
One-time opening and automatic unloading eliminates two full-time operators per shift, requiring only one inspector to monitor the equipment.
Dual dark liquid outlet design seals discharge channels, eliminating splashing. The 304 stainless steel receiving hopper keeps the area clean and orderly.
No significant wear observed in core components after 90 days. The carbon steel frame and stainless steel hopper showed no signs of corrosion or instability.
Customer review
The person in charge of the mining processing plant later sent a feedback:
"The XAZ6/450-30 fully automatic box-type filter press has completely transformed our dehydration operation mode. With fewer personnel handling more materials, the quality of the filter cake exceeded expectations. Just the two functions of blowing air and one-time opening are enough to make this investment well worth it. We are already planning to order a second unit for another production line."
Case Summary
This case conclusively demonstrates that for mining customers facing the challenge of high-yield ore slurry dewatering, the XAZ6/450-30 fully automatic box-type filter press can bring:
- Significantly shorten the filtration cycle through full automation
- Lower cake moisture content reduces transportation costs
- One time, by adopting automatic unloading, the reliance on manual labor was reduced.
- The dual counter-current design creates a cleaner and safer working environment.
- The carbon steel frame and 304 stainless steel components ensure long-term durability.
The successful deployment of this equipment in the high-altitude mining areas of Chile has further verified its reliability and adaptability in various complex industrial filtration scenarios.
