High efficiency dewatering and dry discharge project for iron ore tailings

1. Project background:
A well-known domestic iron ore enterprise is facing land occupation, safety risks (tailings dam), and environmental pressure caused by traditional wet tailings storage.. To achieve“ Green Mines” Transformation urgently requires deep dewatering of tailings slurry to achieve; Dry pile "; Or“ Dry emissions; The standard.
2. Challenges and Requirements:
Processing the tailings slurry with extremely fine particles, poor settling properties, and difficult filtration.. The filter cake is required to have a high degree of consolidation, making it easy to transport and store. The system requires high processing capacity to match the upstream beneficiation capacity. The equipment needs to have a long wear life and adapt to harsh working conditions.
III. Nuclear Xu Solution:
The core equipment of this project isDU type rubber belt vacuum filter:
1.High strength annular rubber belt:Carrying the vacuum chamber and filter cloth, it has excellent tensile resistance, wear resistance, and anti deviation performance, and its service life is twice that of traditional equipment..
2.Nuclear Xu's patented filter cloth regeneration technology:Combining specific chemical cleaning agents and high-pressure water jets, it effectively removes fine particle embedment and solves the core pain point of fine particle material filtration - filter cloth compaction..
3.Multi stage variable vacuum design:Based on the dewatering characteristics of tailings, different vacuum degrees are applied at different stages to optimize the dewatering path, improve efficiency, and reduce energy consumption.. 4. Modular structure: Easy to transport, install, and maintain, especially suitable for remote mining areas.
Fourth, Application Effect and Customer Value:
1.Extreme Dehydration:The moisture content of the filter cake is reduced to below 15%, and it can be squeezed into a ball by hand, and it will disperse when released, perfectly meeting the requirements of dry stacking..
2.Processing capacity:A single device can handle dry basis quantities exceeding 50 tons/hour, fully meeting production needs..
3.Safety and Environmental Protection:Fundamentally eliminating the risk of tailings dam failure, reducing land occupation, and receiving high praise from local environmental protection departments..
4. Cost savings:The transportation cost of dry pile is much lower than that of slurry transportation, and the subsequent reclamation cost is significantly reduced..
