UNTHA LR wood waste shredders

UNTHA’s powerful LR1400 wood shredder is renowned for its incredibly high throughput. Characterised by its reliability and performance even in the toughest wood shredding environments, this machine is mainly used by joiners, carpenters and sawmill operators who have a wood waste volume in excess of 12m³ per week.

Suitable for processing materials such as pallets, solid wood, logs, chipboards, veneers, bark, wooden pallets and MDF, the LR1400 can achieve a homogenous particle size perfectly suited to biomass heat recovery and wood briquette production.

This robust machine includes a hydraulic swing pusher which load-dependently presses the material against the rotor. The rotor is fitted with indexable, interchangeable cutters which grab the wood waste and shred it against the static cutting bars and perforated screen.

Hazardous Waste Shredders

Ever-changing legislation and an increasing awareness of the need to develop safe and environmentally responsible waste disposal methods, mean that the processing of any waste packaging falls under great scrutiny. IBC containers, drums and cartons that have previously housed hazardous substances such as chemicals, acids and alkalis are therefore becoming increasingly difficult to discard.

In just the same way that chemicals need to be stored and processed in a safe and controlled manner, the storage containers must also be handled with care before they enter the waste stream. The co-disposal of hazardous and non-hazardous wastes in to landfill was banned in July 2005. In autumn 2007, the Government also outlawed the crude shredding of IBCs and waste chemical barrels which were then mixed in a pit with lime or other neutralising agents before land filling.

But even the most hazardous wastes pose no problem for UNTHA’s robust specially configured RS shredder series, as mechanical seals and drop-out zones keep aggressive and corrosive materials away from the bearings and gear boxes. Capable of handling up to 205 litre steel or plastic drums, and 1000 litre IBC bottles, UNTHA’s four shaft machines with a ram device allow companies to shred their hazardous waste on site. When the resulting fraction exits the waste shredder it can then be transported using a conveyor belt into a specialist mixing plant, whereby it is combined with a neutralisation agent under controlled conditions, to ensure that the material is inert before final disposal. This chemically neutral substance can then be safely reused; energy can even be harnessed from it.

Medical Waste Shredders

Rather than operating a ‘one size fits all’ approach to waste management, UNTHA’s pioneering engineers have worked alongside organisations in every sector to develop bespoke shredding solutions that satisfy varied application requirements.

When it comes to shredding medical waste such as soiled dressings, surgical gowns, packaging and sharps, organisations need look no further than the heavy duty UNTHA RS series. Special cutter configurations have been purposefully designed for this material type, and interchangeable screens allow the required particle size to be achieved.

This slow speed, high torque machine is a powerful shredding solution. Incorporating the latest design of mechanical seals, the bearings and gear box are protected from any ingress of corrosive materials. This specially configured UNTHA RS series shredder has an intelligent foreign object protection mechanism to prevent damage to the cutters in the event of unexpected items accidentally entering the medical waste stream. Titanium hip joints are a particular problem and are often found in medical waste.

Aluminium Can Shredders

Organisations often approach UNTHA UK to ask what solutions we can provide for the shredding of aluminium drinks cans. Whilst every scenario is different, the UNTHA RS shredder usually lies at the heart of every recommendation.

We often find that, at the waste disposal stage, consumers naturally place things in aluminium cans that shouldn’t be there, for instance blades, cigarettes and wood. This can potentially result in a small amount of waste contamination, which needs to be addressed if operators are to achieve a clean product with a maximum financial return .

Aluminium cans may be fed into the RS shredder loose or in non-rigid bales, and if required the machine can be fitted with a ram device to aid the shredding process. The material is then shredded down to a pre-defined, consistent particle size for optimum recycling. UNTHA UK recommend the use of ferrous magnets and eddy current separators to sort ferrous materials and plastics from the resulting fraction, thus achieving a really clean product.

Using a modular system which allows tailor-made solutions to be devised, the RS can be specially configured for aluminium shredding. For instance the unique UNTHA-designed compressed air system cleans the gaps between the cutters preventing wear and also to giving an indication of cutter damage. This well-engineered design feature achieves cost, time and maintenance efficiencies for users.

Cable Shredders

Waste shredders are being increasingly sought for the processing of old cables, because it is no longer economically viable to export loose cable to China. Instead cables can be sampled, graded and shredded to aid the recovery of copper, lead, steel and plastic.

UNTHA’s slow speed, high torque four shaft technology is perfect for cable shredding because operators can achieve an efficient and safe shred, with the reduced risk of a spark. Interchangeable screens also provide accurate size reduction and particle size flexibility.

If you are a cable or household wiring recycler, browse through the UNTHA RS30, RS40 and RS50 brochures to find out more about these purposeful waste shredders. If you have a specific requirement, for instance the shredding of industrial cables for which we would recommend the RS50, then please contact a member of the UNTHA UK team. It’s what we are here for.

Textile Shredders

Textiles are a notoriously difficult product to shred because the materials can be so inconsistent. However the rugged design and hard-wearing cutter systems of the UNTHA RS shredder handle this tough application with ease.

Materials fed into the machine’s main cutters are pre-shredded and re-shredded in a single operation. Anything that does not fall through the screen is passed on to the secondary cutters for re-shredding, ensuring thorough processing regardless of the nature of the textile.

With configurable speed, torque, cutting systems, screens and sealing variants, this range of flexible UNTHA shredding machines can also be tailored to suit clients’ specific requirements.

ASR (Automotive Shredder Residue)

Whilst predominantly a plastic-based waste, Automotive Shredder Residue (ASR) can come in all shapes and sizes. An incredibly robust machine is therefore required for this type of industrial shredding.

Once scrap vehicles have been fed into a fragger, the resulting items such as seats, dashboards and plastic air filters constitute ASR. However there is still metal waste within this material. A high performance shredder with a sophisticated foreign object protection system is therefore needed to ensure a safe and efficient waste management process.

The world-renowned UNTHA TR shredder is perfect for this application. For instance:

• When foreign matter is detected the machine immediately stops and the door and screen automatically open to prevent any damage to the cutting system. In addidion there is a shear pin coupling to protect the drive mechanism , ensuring safe, efficient and machine-friendly removal of the object

• The machine availability uptime is increased by up to 10% as a result of UNTHA’s patented quick change cutting system

• All machine components are easily accessible via maintenance doors

• The integral heavy duty steel frame structure ensures this machine can handle ASR effectively without problem

• High throughputs are achieved by using a large diameter rotor.

Other shredders you may wish to consider for ASR include:
