Shredder
Another tool in the chip processing system is a simple shredder. The shredder cuts material that can be metered by auger into flowable chips. This shredder is the most cost effective addition to a chip processing system for chips greater than 4" but less than 10" and for material without large solids that can be conveyed in an auger.

RS45 and RS50 series
The design for the RS45 and RS50 series is derived from the logic of the world’s first industrially produced four-shaft shredder, the RS30. Like the RS30, the RS45 and RS50 versions use the shredder design of the patented UNTHA four-shaft system with perforated screen (patent number 319535). Both series are ideal for multi-shift continuous working and particularly difficult operating conditions.

|
RS60 and RS100 series
The RS60 and RS100 have been developed from the RS50 series. Our extensive experience with the smaller series has been incorporated into the design of what is currently the largest four-shaft series available from UNTHA. The RS60 and RS100 machines are also equipped with the patented UNTHA four-shaft system with perforated screen (patent number 319535). With a cutter clearance width of 1.5 m and height of 1 m, the machines in both series are capable of shredding up to 10,000 kg of material per hour with a driving force of 100 kW. The features on offer mean that an extremely wide range of materials can be shredded.

"M" SERIES SHREDDERS
Alongside the traditional 4-shafts equipped shredders, I.S.V.E. proposes a series of single-shaft equipped shredders with pusher-drawer.
These machines are purposely studied to shred thick materials and highly resistant to cut such as plastic blocks and sheets, various types of timber, paper, extruded polymer pipes, etc.
Operation drawings:
A pusher-drawer with hydraulic drive pushes the material towards a tools-holder roller which carries out the first breaking and thanks to its rotation and to the COUNTER-BLADE action makes a first breaking and the shredding of the product.
The product passes through a drilled screen, which allows establishing the final sizes of the material.

RS30 series
The world’s first four-shaft shredder is part of UNTHA’s RS30 series. With this series, the four-shaft shredder and perforated screen invented and patented (patent number 319535) by Anton Unterwurzacher were incorporated into an industrially produced machine for the first time. Over the last 25 years the series has been continuously developed and improved and offers highly sophisticated technology.
The four-shaft shredders in this series can be supplied with three different driving powers and have been a favorite among our customers for many years. The numerous cutter and screen variants, which can be individually combined to suit your requirements, allow the shredder to be used for a wide range of applications, which is why this shredder was also originally known as the "universal shredder".
RS30-450
Cutter clearance [mm] 450x560
Driving power [ kW ] 11/15/22
Through-put [kg/h] up to 1,000
|
|
RS40 series
Immediately after completing the development of the world’s first four-shaft shredder, the RS30, UNTHA started designing a larger series with different cutter clearances. This resulted in the RS40 series, which also featured the patented UNTHA four-shaft system with perforated screen (patent number 319535) used in our RS30 series (a range which was already proving to be very successful). Larger cutter clearances and significantly higher driving powers allow this series to be used in a much wider range of applications. A broad range of cutters is available and can be combined with different versions of the perforated screen for specific tasks. Driving powers of up to 37 kW provide through-put rates as high as 3000 kg per hour.

Tires and rubber
Shredding is the only way to reduce the growing mountain of used tires. UNTHA has therefore developed special cutters for two and four-shaft machines for this very purpose. Depending on the intended use, both shredder systems can achieve a defined rubber granule size of 20 to 100 mm and larger. The rubber granules produced are mainly processed further in recycling plants, e.g. granule factories, or burnt in cement works as an alternative energy source.

LANNER® chip crushers are suitable for breaking up steel wool, stainless steel, titanium, aluminium, brass and cast chips that are high in oil content. The broken, free flowing chips achieve around 20% of their original volume depending on the type of material.
Chips from high-alloyed or rough materials are not a problem for our chip crushers. The robust design of the electromechanical motor means you can apply ideal crushing parameters. You have the option of a hydraulic motor for chips with a high percentage of bulk. Added bulk such as rods or turned parts are removed from the crushing area by automatic bulk separators. If bulk like this does end up in the crushing funnel, the motor switches itself off. Then a part of the crushing wall opens. A quick reversal of the knife head sends some of the already crushed chips and the bulk part out through the open hatch. Then the hatch closes and the crusher starts up again.
An SPS controller in the control box manages the disturbance function on a fully automatic basis.

Crushing of large swarf is a prerequisite for automatic swarf processing and cost-efficient transport.
THE ADVANTAGES OF THE STEIMEL- SWARF CRUSHER TYPE RS:
- High crushing performance with low energy requirement
- Low noise crushing
- Good accessibility of crushing chamber
- Can be integrated in any swarf processing system
- Long service life of low wear crusher tools
- Low maintenance cost due to quick replacement of wearing parts
- No special foundations required (B25 sufficient for dowel fixing)
THE FUNCTION:
Long swarf is fed into the crusher hopper by swarf conveyor systems or other means. By an ultrasonic sensor at the crusher hopper the crusher is automatically switched on and off.
The long swarf in the crusher hopper is drawn by the tearing arm. Supported by guiding hooks it is first transported to the coarse crusher and then to the fine crusher. The broken short swarf is discharged by two wiper blades via a chute.
Small sized solid parts usually pass through the crusher without blocking. Larger parts and bar-ends which might block the crusher initiate the blocking control. A reversing sequence is automatically started to discharge the solid parts. If this is not possible after several clockwise and counter-clockwise rotations of the crusher head the crusher stops. The blocking material can then be removed through the inspection hatch. Due to the typically inclined position of the STEIMEL crushers there is hardly any spilling of swarf or coolant.

The HAMMEL KompBio is a multi talent. Different machines are united in one:
* primary shredder
* screen
* secondary shredder
The HAMMEL KompBio works in several steps. In the first step the feeding material, for example:
* biomass
* fresh wood
* root stems
* tree stems
* compost
* wet wood
* waste wood
is pre-shredded, afterwards it drops on the integrated disc screen, where organic and mineral parts are separated and discharged. The here generated end product is suitable for composting.
The clean, pre-shredded wood is then carried to the secondary shredding step. Exchangeable screen baskets and the design of the secondary unit guarantee an exact and regular end product with almost 100% constant chip size according to further usage of the crushed material (composting or energy utilization).
The secondary shredder, integrated in the HAMMEL KompBio, produces chips with a size of approx. 40 mm to 100 mm (depending on the size of the screen basket). Alternatively, the HAMMEL KompBio could be used as a windrow turner. For this purpose the screen basket of the secondary shredder is kept open during the shredding process.
In case the material contains metal parts, the HAMMEL KompBio can be optionally equipped with a magnet. By the way, our multi talent does not only shred wood but also a multitude of other materials.
