Clear Edge’s 29076K polyamide filter cloth consistently exceeded service life targets, achieving breakthrough results in zinc purification processes.
Enhanced Performance Drives Repeat Orders for Zinc Refinement.
Polyamide Filter Cloth 29076K Secures Repeat 1000-Cloth Orders.
Clear Edge collaborated with a global mining and metals producer to optimize filter cloth performance for zinc purification. The process required robust fabrics to withstand operational challenges and meet a stringent 3000-cycle performance benchmark. After introducing the newly developed 29076K polyamide filter cloth through rigorous trials, Clear Edge exceeded expectations with a service life surpassing 4000 cycles. This exceptional performance resulted in two large-scale orders and bolstered Clear Edge’s reputation as a reliable technical solutions provider.
THE CHALLENGE
Delivering Consistent High-Performance Filter Cloths.
The challenge was to meet or exceed the 3000-cycle benchmark consistently while addressing cake release, cleanliness, and blinding issues.
- Site operated multiple Metso VPA 15 filter presses, requiring one to be constantly in maintenance.
- Target cycle life of 3000 was rarely achieved consistently by previous suppliers.
- Required robust monofilament fabric for easier cleaning, lower residue, and reliable cake release
THE SOLUTION
Optimizing Performance Through Rigorous Trials.
Clear Edge tailored solutions through onsite discussions, trials, and detailed evaluations to exceed expectations.
- Conducted preliminary trials and facilitated discussions on-site with Clear Edge technical and sales representatives, as well as via conference call with site engineers and the Clear Edge development team.
- Tested two filter cloth variants: polypropylene and polyamide (29076K).
- Ran a 260-cloth trial, assessing cycle count, cleanliness, and cake release.
- Enabled side-by-side comparisons under real process conditions.
- Provided detailed trial data showcasing longevity and efficiency metrics.
- Offered technical guidance to refine filtration setups for optimal results.
THE RESULTS
Record-Breaking Performance and Unmatched Endorsements.
Consistent success drove repeat orders and wider industry adoption of the 29076K fabric, highlighting the performance benefits of its polyamide yarns and specialized duplex weave pattern.
A press operator remarked, ‘We are very pleased with the performance of these cloths; we definitely want more!’
- Initial trial cloths achieved 4000+ cycles, surpassing the 3000-cycle target.
- Secured an order for 1000 cloths in May 2024, followed by another in October 2024.
- Received unprompted praise from a filter operator during a follow-up visit.
- Word-of-mouth recommendation led to an additional order for a nearby silver mine.
