New generation spider shredder makes an impression

Colin Irons, National Sales Manager, from Fercell Engineering/WEIMA UK, specialists in the design, manufacture and installation of shredders and briquetters looks at the new Spider HRS Shredder and its appeal as a high security, high capacity solution (Level 4 to DIN 32757). “The confidential data destruction and confidential waste management sectors are showing more than just a passing interest in the new Spider HRS Series”, he commented. “With what appears a softening market in the UK, site efficiencies and plant flexibility have now become the new targets in the attempt to hold the bottom line.

The UK recycling sector in general, continues to demonstrate its insatiable thirst for plant flexibility, increased plant efficiencies, and future-proofing considerations as key drivers during the investment decision process. Putting aside external pressures like the current volatile material market, recyclers are focusing on internal operating costs, favouring plant proven to lower operating overheads, decrease maintenance downtime cycles and deliver a multi tasking capability across differing materials, at the same time retaining affordability.

The three Spider HRS models, now available to the UK, through the sole UK distributor Fercell Engineering of Aylesford, Kent, follow in the mould of the WLK series single-shaft shredders, to be launched as a new generation of shredder. The Spider HRS list of new features and improvements is an impressive one. Appealing to the confidential data sector in the Spider HRS capability of processing Computer Hard drives, CD/DVD, VHS tape cassettes, paper etc. in one machine.

Principally the Spider HRS is equipped with an interchangeable pressing system designed to handle a variety of materials to include lumps, film, sheet and hollow moulds. The modular pressing systems are 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 system hydraulics, installed beneath the machine housing, can be fully removed via a sliding draw providing quick access to minimise maintenance down time.

This new generation breed of 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.

Single-shaft shredders are supplied in rotor widths of 1000 mm, 1500 mm and 2000 mm, with a rotor diameter of 450 mm, delivering rotational speeds of up to 150 rpm.
