Visitors to the recent K 2010 trade fair in Dusseldorf, Germany would have seen the truly innovative modular shredder offering from WEIMA Maschinenbau GmbH called the Spider HRS Shredder Series. The Spider HRS Series is a new breed of shredder, within the WLK mould, incorporating a number of new and unique developments to shredding technology.
The three Spider HRS models within the series of WLK series single-shaft shredders is equipped with an interchangeable pressing system designed to handle a variety of materials to include; lumps, film, and hollow moulds. The modular pressing systems are incredibly quick to replace, making it effortless to tailor the machines to different material flows, even after years of operation. And because there is unrestricted access to the cutting system, cleaning and servicing are quick and easy to perform.
The pressing systems are guided over belt-retaining strips - attached externally for straightforward replacement - and stored on plastic rollers for optimum system guidance and jamming prevention. Furthermore, the pressing system hydraulics installed beneath the machine housing can be fully removed, providing quick access for maintenance work. What's more, the pressing systems are controlled using a position-measuring system.
The new single-shaft shredders are generally equipped with a hydraulically-driven swivel screen basket, a mechanism that helps to prevent jamming of material between the rotor and the inner screen wall. The screening surface around the rotor has also been increased for faster material output, while the reduced size of the individual screen elements make screen replacement easier than ever before.
