The advent of a need to reduce the volume of green and other waste removed from sites means that shredders and chippers have become more popular in recent years, and not just for tree surgeons. It is shredders, however, that are more suited to handling a wider variety if material that is found on reclamation and landscape sites, we look at what is available in the market.
Chippers International offer the Gandini range of shredders, featuring machines that are either tractor mounted, tractor trailed or trailed with their own diesel engine. The Biomatich Line range includes the 79, 81 and 85 models – TPS variants are three point linkage mounted and require from 30-100hp, as do the TTS tractor trailed units whilst MTS versions feature 2, 3 or 4 cylinder diesel engines to drive the shredder, ranging in power from 20 to 50hp.
Across the range, rotor diameter is a standard 500mm and width is 250mm on the 79 and 81 models; 400mm on the 85 with feed openings of 260 x 150mm on the two smaller models and 410 x 220mm on the 85. Claimed outputs per hour of 12 to 25 cubic metres per hour depending on model and material diameter that the machines will handle varies from 130mm to 160mm. A neat feature is the self-sharpening rotor hammer system, with a claimed 800 hour maintenance free period. Also available is an optional CTP electronic feed device, which allows material through at a regulated pace according to the rotor speed and load. Fibreglass covers are fitted on these machines to aid in the reduction of noise levels and trailed machines offer a rotating body to enable the operator to feed material in at the most convenient angle and still alter the spout.
Larger machines from Chippers International include the Gandini Biomatich 89 and 91. These are bio shredders capable of handling larger volumes of waste (claimed up to 60 cubic metres per hour) and designed to be operated by 80 – 100hp tractors (TTS version) or powered by their own 122 and 172hp diesel engines (MTS version). These machines are aimed at working on composting and storage sites and moved either by tractor or lorry.
A heavy-duty rotor features 30 or 40 hammers placed in 10 rows, to a width of 1000 or 1200mm depending on model with a maximum opening of 400mm. Each hammer weighs 3kg and Gandini indicate that each one will last around 150-250 hours depending on material throughput. The machines are also capable of processing domestic rubbish as well as usual landscaping and green waste, and output can be via an optional rear conveyor to a stockpile.

Arbor Eater Brushwood Chippers market the Pezzolato S4000 and S7000 shredders to the UK market. The S4000 version will handle up to 140mm material and is said to cope with green waste, broken pallets, wood and other material such as glass and some plastic. A production rate of 10 to 12 cubic metres of material per hour is claimed using 48 double-sided hammers on the rotor. A hammer life of 50-100 hours is expected but this is dependent on the material processed and when the hammers are turned. A Hatz 33hp diesel engine powers the S4000 and the 360 degree unit sits on a trailed chassis for easy movement by truck or tractor. A computer controlled easy loading system means that material is fed to the rotor at the correct speed to reduce overload, and output is via a conveyor that is capable of being raised to 2.6m.
The larger S7000 model from Arbor Eater features 62 hammers on its 530mm diameter rotor and offers a 0.5 cubic metre intake hopper for easier loading. A claimed output of 20 cubic metres per
hour offers rapid shredding for all types of users, and the machine will handle a variety of materials that the contractor, council or landscaper can throw at it. Mounted on a 360 degree body and twin axle chassis for up to 80kmh towing speed, the S7000 features a hydraulic roller feed that assists with material flow into the rotor unit. A screener handles the material before it exits via the output conveyor for loading or stockpiling. Arbor Eater reckon a hammer life of between 100 and 250 hours dependent on work, and the 4 cylinder engine is controlled by an anti stress system to reduce revs when the engine load becomes too, allowing material through before building revs up again.

Timberwolf UK offer one professional shredder in their range of wood and waste handling products. The TW S425 machine is powered by a 45hp 4 cylinder Kubota turbo diesel engine and can handle a claimed throughput of around 3 tonnes per hour, dependent on the material to be shredded. An in feed dimension of 768 x 458mm means fairly large material can be fed into the autofeed system to the rotor. The hydraulic powered roller is driven by a high torque motor and controlled by an autofeed control system that alleviates stress and provides an auto backoff function. This system works with an autofeed system to give an even flow of material and means that it is fed back in with the hammers under less or no load. A safety bar prevents operators accessing the feed tunnel and dual controls either side of the machine help reduce the need to stand near the intake of the machine. A half length safety curtain just forward of the feed roller not only protects the operator but leaves enough view to ensure there is no need to push material through, as is the case with full length curtains say Timberwolf. Shredding is carried out by 18 swinging hammers – which are easily replaceable – and these can handle multiple material types in a variety of applications. Air paddles are also part of the 425’s system – this air flow is said to ensure a quicker discharge with soft or green material such as brash or cuttings. A 270 degree tube discharges into a truck, trailer or bin, but not towards the operator area.
Due to be launched at Saltex 2007 is the S426 model shredder from Timberwolf. This upgraded machine replaces the S425 machine with a host of new features, and is aimed primarily at the local authority and contractor market who demand a low weight, compact machine with high throughput.

Westcon Equipment (UK), supply Jenz shredders into UK users. The Jenz machines are aimed at professional users, councils and contractors and are capable of handling vastly superior quantities than smaller van towed machines. Westcon supply a variety of machines to the market, but the three smallest find favour with many small to medium users.
The smallest model is the Jenz AZ 30-80, which was the first Jenz machine to be mobile. Powered by a Perkins 100hp engine, the 30-80 has a claimed output of 25 cubic metres per hour in green waste, and 60 cubic metres per hour with bark. A 620mm rotor diameter features 22 hammers and output is via an optional conveyor.
Moving up the scale somewhat is the Jenz AZ460D. This is powered by Daimler 280hp engine and can be fixed, towed or on tracks dependent on application. Capacity wise, Jenz claim green waste output of 80 cubic metres per hour, bark at 140 cubic metres and scrap wood at 50 cubic metres so outputs can be very high for contractors who have vast tonnages to clear. An 820mm diameter rotor with 30 hammers handles the material and output is via optional conveyors to a heap or lorry. A monster machine in the Jenz range is AZ660 shredder, which is supplied with either a 430 or 490hp Mercedes engine. It can handle green waste at up 170 cubic metres per hour, bark at 220 cubic metres per hour and scrap wood at 110 cubic metres per hour so is capable of high level performance. Featuring a hammer mill with 38 hammers on its massive 1.04m diameter rotor, the AZ660 can vary the speed of flow according to the operator’s needs. Screens and conveyors are available in different configurations as required.

Another importer of larger equipment is CGCS (Midlands) Ltd. who market the TIM envipro range of shredders. A four models range encompasses machines with capacities from 25 to 120 tonnes per hour. The company not only sells these machines but hires them out and supplies used and reconditioned units, which are more suited perhaps for the landscaper wanting more capacity with a more permanently sited shredder.
TIM machines are Danish built and offer a sturdy construction. The SD 1360 and 1430 models are designed for shredding green waste and demolition wood. Featuring engines from 354 to 428hp, these models feature a computer to optimise throughput of material, which can be anything up to 150mm diameter and at rates of up to 280 cubic metres per hour. The flexibility of these machines is their key feature – a wide range of materials can be taken and handled with the hydraulic feeder roller and through to the 28 flails, each weighing 15kg. A variety of options include conveyors and metal detection system.
The larger brothers of the SD1360 and 1430 are the SD1600A and SD1600XL. Both machines are versatile and flexible in their uses, and both have a 600hp John Deere engine. The A designation differs from the XL in its chassis design – the A spec machine is towed via a drawbar, the XL by a fifth wheel system plus it has a triple axle setup for increased capacity. Both are capable of massive outputs and include similar features to the smaller models, including the same rotor size and hammer quantity. Screen areas can be changed from 50x50mm up to 300x300mm as required, and a total area of 4.3 square metres is standard. An optional 9m long conveyor allows for a heap of nearly 5m to be created, and extension sides allow for more capacity on the intake hopper if required.
