Parnaby Cyclones rebrand and launch two innovative recycling solutions.
A long-established family owned company, Parnaby Cyclones has designed, manufactured and installed washing plant and equipment for the mining, quarrying, and mineral industries all over the world since 1973.
Through this global presence the Parnaby name has grown through the coal industry where they are known for outstanding customer service and robust, long-life equipment. This vast experience has brought additional confidence with their technology within the recycling sector which began 15 years ago and subsequently led to the design and manufacture of a Natural Medium Trial Wash Plant which was installed at their Chilton HQ three years ago.
Since then the plant has been used as a test bed for processing a wide variety of materials for several companies all of which have proved successful. This success has led further to the rebrand of the company and to introduce new innovative processing solutions for the recycling sector. The Parnaby process offers many benefits of wet separation, including:
- Volume reduction of landfill material
- Increased yields to high grade products
- Increased flexibility on feed moisture content
- Increased flexibility to process heavily contaminated mixed waste
- High throughput capability for improved payback time on capital expenditure
- Robust and flexible design for long life cycle and good residual value
- Ability for mobile/modular design for short-term projects
Incinerator Bottom Ash (IBA)
Parnaby Cyclones can offer two ‘market exclusive’ wet separation solutions which have been applied on IBA type material Both these solutions provide a volume reduction to landfill through highly efficient separation and create clean high-grade products for revenue generation.
Based on the Parnaby Cyclones Dense Medium Solution, bespoke designs are available to suit client requirements which provide improved separation efficiencies compared to dry separation. These solutions provide cleaned aggregates with aluminium from heavy ferrous and non-ferrous metals within IBA material from waste to energy systems.
Utilising the Parnaby Cyclones Natural Medium Solution they can offer a process which offers high throughput capabilities providing an efficient method of recovering unburnt material from IBA out of waste to energy systems and biomass power generation. This introduces a wet separation process which facilitates significant cleaning to create high-quality products providing attractive business models with reduced landfill costs.
This offers many benefits, including:
- High efficiency whilst maintaining high throughput
- Volume reduction to landfill whilst producing tangible products for revenue
- <5% Loss on ignition (LOI) on dried ash product
- <5% ash content in dried recoverable biomass product
- Improved efficiencies of existing eddy current and dry separation systems
- Short payback period on capital expenditure
A recent project for IBA biomass processing, Parnaby Cyclones supplied a 50-100tph Natural Medium Cyclone Plant with closed circuit effluent treatment. The plant processed a <20mm contaminated feed and achieved up to 99% wood recovery of >200um at 2% ash content. This produced an ash product up to 98% purity. The end result provides a wood product that is compatible for re-burning, and an ash product that is compatible for concrete block manufacturing.
In a further project in Belgium Parnaby Cyclones designed a 25-30tph Natural Medium Barrel and Cyclone Plant in conjunction with eddy current separators and closed circuit effluent treatment. Processing a contaminated feed of <100mm the wet process improved efficiency and throughput of magnetic systems and produced a concentrated aggregate for resale. The plant also produces a high-grade ash product for concrete block manufacturing and recovers ferrous and non-ferrous products for re-sale. In applications of this nature Parnaby Cyclones can supply Dense Medium options for further bespoke separation requirements.
Municipal Solid Waste (MSW)
Parnaby Cyclones offer a wet separation solution for MSW trommel fines with their Natural Medium Solution which offers many benefits, including:
- High throughput of up to 60tph with cost efficient scalability
- A heavy-duty design with robust construction providing high residual value and plant longevity
- New opportunities for processing highly contaminated raw feed stock
- Increase efficiencies of dry separation systems
- Low operating costs per feed ton
- Effective weight reduction to landfill
- Produces a clean aggregate for revenue generation
Parnaby Cyclones Wet Separation Processes can achieve a <4% moisture on course and fine aggregates >1mm. The process has the potential to extract course fibre for Refuse Derived Fuel (RDF) and Anaerobic Digestion (AD) materials and can produce a light, clean material stream for further dry separation to produce an RDF. Lastly, the process can also produce an organic rich filter cake product with AD compatibility.
A recent project processing MSW, Parnaby Cyclones supplied a 35tph Natural Medium Barrel Plant with closed circuit treatment. The plant processed a contaminated feed of <80mm trommel fines and achieved a <6% moisture course and fine aggregate. Furthermore, the plant achieved an AD grade organic filter cake product and lastly produced a compliant product for processing to produce an RDF.
Recent successful projects
Parnaby Cyclones Wet Separation Processes have been successfully applied to many recent projects. For a project involving C&I – soil remediation Parnaby supplied a 50tph custom Washing Drum Plant with closed circuit effluent treatment. Parnaby were appointed as principle contractor and designed a plant that was adaptable to hugely variable feed stock, including clay and hydrocarbon contamination. The plant has successfully reduced the volume of contaminated discard and produced saleable products. Parnaby have recently managed and installed an expansion of the system for further fines density separation.
In Italy Parnaby Cyclones designed and installed a plant to process MRF glass by supplying a 35tph Natural Medium Barrel Plant with closed circuit effluent treatment. Receiving a combination feed of <50mm and <4mm crushed glass the plant achieves <0.3% LOI on the 1mm-50mm glass and boasts a 99+% glass recovery. The process has also improved the efficiency of dry separation systems, while processing raw feed.
For a project processing WEEE Parnaby supplied a 20tph Natural Medium Cyclone Plant with closed circuit effluent treatment. Receiving a combination feed of <20mm the plant achieves up to 99% recovery of copper and achieves a mixed plastic cullet. Again, improved efficiency of existing dry separation systems whilst processing raw feed has been noticeable.
An international reputation
Parnaby Cyclones has an international reputation for excellence and service and provides a comprehensive service including consultation, design, manufacture, installation, after sales service and maintenance.
Parnaby Cyclones HQ is located at Chilton, Durham where all equipment is manufactured in-house at their 20,000 square metre site.
