Our Customer

Hadfield Wood Recyclers, part of the Enva family, is one of the oldest and biggest wood recyclers in the UK. With over 38 years of experience in the industry, Hadfield handles wood waste for many national and international waste management companies, local authorities and other public sector bodies, as well as industry including construction and retail.

Hadfield operates three main sites within the UK (Manchester, Middlesbrough and Tilbury), where they process over 300,000 tonnes of waste wood a year. The wood is processed into more than 20 sustainable products including wood fibre animal bedding, feedstock for panel board, and biomass for large and small-small-scale boilers in the UK and Europe.

The Challenge

At its Tilbury facility, Hadfield processes thousands of tonnes of waste wood every week. The raw waste wood must be treated through their multi-stage process before being stockpiled, ready for shipping to various destinations.

Hadfield had previously operated a Haas Tyron 2000 pre-shredder, as the initial stage of their process. This slow speed shredder had reached an impressive 12,000 hours of operation before Hadfield decided they required a new machine.

It was vital for the replacement pre-shredder to produce a consistent particle size, at the desired tonnage per hour. This was crucial for Hadfield, as their third stage of recovery was a manual picking station where a consistent particle size is needed for efficiency.

The desired throughput of 40tph was specifically required so that the stream of shredded wood entering the picking station was not too deep as to hide any foreign objects / impurities, whilst still producing enough throughput to meet their operational requirements.

Being the first stage in a multi-stage process, the size of particle, and the speed at which the particles are expelled from the pre-shredder is crucial to the success of the entire process.

Hadfield again came back to CRJ Services for a solution, having already purchased two Haas Tyron pre-shredders previously. This machine would have to be capable of hitting their operational targets, as well as fitting seamlessly into their existing process.
