The application of the 630 automatic hydraulic box-type filter press in the tailings slurry dewatering project of a mining company in South America

2026-06-01

Project Background

A mining company located in South America mainly engages in the screening and flotation processing of copper ores. The beneficiation workshop generates approximately 30 cubic meters of tailings slurry every day, with a solid content of about 25%. The particles are fine and contain a small amount of residual flotation reagents. The customer's original centrifugal dewatering equipment has high operating energy consumption, is prone to wear, and has a high moisture content in the output, resulting in high costs for tailings storage and transportation.

Solution

The client contacted us through the online platform and made the following requests:

The equipment needs to be able to handle fine-grained tailings and should not cause the filter cloth to get clogged.
The moisture content of the discharged material should be lower than 20%, which is conducive to dry storage.
There is no centralized drainage system on site. The filtrate must be clean and reusable.
The equipment is simple, reliable and easy to maintain.

We have recommended the automatic hydraulic box-type filter press (with center-feed system) and made targeted configurations:

Rack:Carbon steel (reinforced)

Filter plate:Reinforced PP, 630×630mm

Filter cake thickness:30mm

Feed method:Center feed

Discharge method:Counterflow

Feed pressure:0.6 Mpa

Compression:Automatic hydraulic

Pulling plate:Manual pulling of the plate

Operation results

Two months after the equipment was officially put into use, the customer provided the following feedback:

Filter cake moisture content: Stabilized at a range of 17% to 19%, which is better than the requirement of 20%.

Processing capacity: Each batch can handle approximately 2.5 tons of dry solids, with 4 to 5 batches per day, fully meeting production requirements.

Filter liquid quality: The suspended solids content in the filter liquid collected at the underflow outlet is less than 150 ppm, and it can be directly pumped back into the flotation process for reuse.

Energy consumption: Compared to the original centrifuge, the electricity consumption per unit processing volume has decreased by approximately 40%.

Maintenance status: The manual plate pulling mechanism has no electronic faults. After the workers become proficient in operation, they can independently complete the cake unloading task every shift.

Customer Review

"The performance of this filter press exceeded our expectations. We were initially concerned that manually pulling the plate would affect efficiency, but in fact, the cake discharging speed was very fast, and there were few fault points. The undercurrent design eliminated the problem of muddy water flowing in our workshop, and the environmental inspection was also successfully passed. What we are most satisfied with is the clean filtrate, which has helped us save a large amount of industrial water."
