The ION2 Hydro-mechanical belt filter (ION2 HMBF) is used for the screening and de-watering of primarily coal slurry but can be adapted for use in other mineral beneficiation processes. The ION2 HMBF differs from other screening and de-watering methods in that it actually increases the permeability and porosity of the material being treated, by reducing the potential for consolidation and settlement of the fines through it’s unique, patented* use of vacuum, pneumatic agitation, hydraulic placement and mechanical handling of the product. This means that screening efficiency is increased and de-watering ability improved.


• Modular design increases versatility of the system

• Screening of +100 micron particulate
• De-watering of +35 micron particulate
• 15 - 20% moisture content achievable
• Up to 100m3/hr slurry volume can be handled (30% solids)
• Low initial capital and running costs
• Low energy usage
• Simple operation - Low skills required
• Self cleaning to prevent filter blinding
• Rapid water recovery through continuous process
• Product discharge directly into other product streams
• Reduces environmental risks
• Either manual or fully automated control and monitoring
• Small footprint
• Quick return on investment
• Manufactured to ISO 9001-2000 quality standards
• 100% designed and manufactured in South Africa
