HAAS TYRON 2000XL 2.0 - Wood
Background
Hadfield Wood Recyclers (Enva Ltd) is one of the oldest and biggest wood recyclers in the UK. With over 38 years of experience in the industry, Hadfield handle wood waste for many national and international waste management companies, local authorities and other public sector bodies.
Hadfield operate three main sites within the UK (Manchester, Middlesbrough and Tilbury), where they process vast quantities of waste wood. This wood is processed and then recycled into over 20 sustainable, saleable products such as wood fibre bedding or it is sent to small and large-scale biomass facilities as fuel.
Challenge
At their Tilbury facility, Hadfield process 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.
In order to increase the quality of their recovered material, Hadfield Tilbury needed to refine their existing process. Their existing pre-shredder, a Hammel 750, was the first stage in the recovery. It was struggling 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 required so that the stream of shredded wood entering the picking station was not too deep as to hide any foreign objects / impurities, but not sparse enough to decrease the facilities required tonnages.
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 came to CRJ Services Ltd for a solution capable of hitting their operational targets, as well fitting seamlessly into their existing process.
Solution
After a thorough discussion to identify Hadfield’s requirements, CRJ Services suggested that the Haas Tyron 2000XL 2.0 (7-7/4) with its twin shaft setup, would be able to consistently produce the required particle size, at the desired tonnage per hour.
Hadfield then had several different machines bought to site for a period of demonstrations, where 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”.
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 overband magnet, at the correct height and angle. Hadfield also wanted the first overband magnet, attached to the Tyron’s outfeed conveyor, to expel the ferrous metal a further away from the machine, then was seen in the demonstration.
CRJ Services 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 overband magnet. Haas also successfully customised the overband magnet, to extend further from the outfeed conveyor, so that metals collected by the magnet are expelled the desired distance from the shredder.
