Customer Background
The customer is a medium-sized copper mining enterprise located in the Antofagasta Region of Chile, mainly engaged in the mining and initial processing of copper concentrates. The mine’s daily processing capacity is approximately 600 tons. The existing filter press equipment is old and has problems such as high moisture content in the filter cake, low efficiency of manual discharge, and rapid wear of the filter cloth. The customer hopes to introduce a fully automatic solid-liquid separation system to reduce the transportation cost of tailings and improve the utilization rate of return water.
Solution
We provided this customer with a fully automatic box-type filter press (Model 1000, carbon steel frame, concealed liquid outlet). It integrates automatic hydraulic pressing, automatic hole blowing, automatic plate pulling, and automatic vibration discharge. The filter plates are made of corrosion-resistant PP material. The filtration area was configured according to the customer’s requirements. The filtration pressure is set at 0.6 MPa, ensuring that the thickness of the filter cake is stably controlled at 30 mm. The machine interface adopts an HG flange with an imported DN80, seamlessly connecting with the customer’s existing pipelines.
Operation Effect
-
The moisture content of the filter cake decreased from the original 28% to below 22%, significantly reducing transportation weight.
-
The automatic vibration discharge system reduces discharge time by 8 minutes per cycle, and the need for manual intervention is reduced by approximately 70%.
-
Slurry leakage is prevented, avoiding splashing and improving the workshop working environment.
-
The constant 30 mm filter cake thickness facilitates subsequent stacking and transportation.
-
The suspended solids content in the return water is lower than the customer’s expected standard, allowing direct reuse in the production process.
Customer Feedback
The production manager of the mine stated: “This filter press truly operates fully automatically. From pressing to discharge, there is basically no need for manual intervention. The hole blowing and vibration functions are particularly practical. The filter cake is very dry and is discharged very cleanly. We plan to purchase another one next year for another production line.”
Case Summary
This Chilean copper mine successfully addressed the issues of low tailings dewatering efficiency and high labor costs by introducing the fully automatic box-type filter press, achieving waste reduction and water resource recovery. This solution is also applicable to solid-liquid separation requirements in other mining, chemical, and environmental protection industries.
