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.
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 Matpro Machinery 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.
After a thorough discussion to identify Hadfield’s requirements, Matpro Machinery suggested that the Haas Tyron 2000XL 2.0 (7-7/4) with its twin shaft configuration, would be able to consistently produce the required particle size, at the desired tonnage per hour.
Hadfield then had several different machines brought to site for a period of demonstrations, so they could get a feel for the options available to them. Following the demonstrations, Hadfield chose the Haas Tyron as their preferred machine. Speaking with Steve Greenwood – Remote Sites Manager, we asked him why the Haas Tyron was selected? “We choose the Haas Tyron 2000XL 2.0 as it gave the best crushed material and TPH when on demo put against the other machines,” he said.
As previously mentioned, the selected pre-shredder would have to seamlessly fit into their existing process. This was a challenge, as the standard Tyron 2000XL 2.0 outfeed conveyor would not reach the second stage of their process, a second over band magnet, at the correct height and angle.
Matpro took this information away, and in collaboration with Haas, developed solutions to the challenges. A custom, hydraulically controlled, extended outfeed belt was developed to fit seamlessly between the Tyron shredder and Hadfield’s second over band magnet. Haas also successfully customised the over band magnet, to extend further from the outfeed conveyor, so that metals collected by the magnet are expelled the desired distance from the shredder.
One year on from the sale of the Haas Tyron to Hadfield – Tilbury, we went to visit Steve Greenwood – Remote Sites Manager to see how the custom Tyron pre-shredder was performing.
1. Why was the Haas Tyron chosen?
The Haas Tyron gave best pre-crushed material and TPH when on demo put against the other machines.
2. What throughput do you get from the Tyron?
40tph, but can go higher but may compromise quality into the picking station with the feed being too deep.
3. How has the Haas Tyron performed?
Very well, with a good back up from Matpro engineers
4. Would you recommend the Tyron?
5. How would you rate the service you have received from Matpro Machinery?
5.a. During the purchasing of the machine?
5.b. The after sales support following the purchase?
Good support with parts, engineers and advice.
