Size reduction is key

Published:  08 July, 2011

The UK recycling sector demonstrates an ever-increasing thirst for plant flexibility and increased efficiencies, with future-proofing considerations now becoming increasingly important during the investment decision process.

Putting aside external pressures of volatile material markets, recyclers are now more focused on internal costs, favouring plant proven to lower operating overheads decrease maintenance downtime cycles and deliver a multi tasking capability across differing materials; while 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, while following in the mould of the WLK series single-shaft shredders, are a new generation of shredder. The Spider HRS list of new features and improvements is an impressive one.

Principally the Spider HRS 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 quick to replace, making it effortless to tailor the machines to different material flows, even after years of operation.

Because there is unrestricted access to the cutting system, cleaning and servicing are quick and easy to perform.  Furthermore, 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.
