Dewatering Screens
Application and Kwatani Product
- Kwatani’s dewatering screen range features horizontal, inclined and multi-slope screen deck design options to ensure optimal water recovery from feed material.
- Kwatani’s custom dewatering screens offer excellent dewatering of wet material at high load capacity while retaining fine particle material in the screen bed. The dewatered material can be more easily handled, conveyed and stock-piled.
- The G-forces resulting from Kwatani’s ideal combination of amplitude/stroke and speed effectively squeeze water out of the screen bed.
- Test specific feed material Kwatani’s wet and dry material testing laboratory.
Kwatani Performance Benefits
- Kwatani dewatering screens are custom designed to meet the specific process requirements and ensure superior water removal without losing excess fines.
- Kwatani’s mechanically robust designs handle the harshest mining applications.
- In-house finite element analysis (FEA) on each custom design for optimum performance.
- Kwatani screens are designed for high load capacity, improved wear life and lower operating cost.
- Minimal maintenance required.
- Epoxy between bolted side plate assembly surfaces for additional corrosion protection.
- Kwatani also offers retrofit replacement screens that improve metallurgical screen dewatering performance while seamlessly matching the structural footprint of existing plant infrastructure with minimal structural modification.
Kwatani Configuration and Range
