Cutting without a break – Increasing process reliability in sawmills with metal detectors

Apart from hazards due to nails or fence pieces, burdens from the last war are still a problem when processing large logs. The handling of ingrown munition remnants is still part of the daily business of a sawmill on the German-Belgian border …

Mesutronic presents itself at the LIGNA 2019

From the 27th to the 31st May the international wood industry meets at the LIGNA in Hanover.

The LIGNA maps the entire value chain of the wood industry. Here is where the top decision-makers and an interested specialist audience from the industry meet. In hall 25 at our booth H 46 we present our reliable and safe metal detectors.

Our specialists are looking forward to many interesting discussions about “Metal Detection Made in Germany”.

 

 

Mesutronic once again presents reliable metal detectors to the wood industry at the LIGNA

Kirchberg i.W./Hanover. The international wood industry will meet again from 22 to 26 May 2017 at the LIGNA in Hanover. The LIGNA covers the entire value creation chain in the wood industry. This is where the industry’s top decision-makers and interested trade visitors meet.

Mesutronic metal detectors for the protection of production machines

We also have interesting machines for the wood industry at our LIGNA trade fair booth. Our metal detectors and separators will certainly be of interest to top decision-makers in particular, since the use of our devices protects sawing systems, shredders, choppers or pellet presses against harmful metal parts.

Metal detectors save money

We are presenting our reliable, safe, money-saving metal detectors at Booth H 46 in Hall 25. Amongst others we are presenting the METRON 05 D. The separable tunnel-type metal detector is used on conveyor belts and in vibrating trough feeders and material chutes. The detector makes use of practice-oriented and reliable technology that has proven itself in use over many years. The device is quick to mount and provides high detection accuracy, even in the harsh industrial environment. A worthwhile investment that protects valuable production equipment.

METRON 05 VT impresses through price/performance ratio

We are also presenting the METRON 05 VT metal detector for direct installation in the trough of a vibrating trough feeder. The reliable detector is quick and easy to mount in all common trough shapes and impresses with its price/performance ratio.

Our experts will be glad to advise you

Our experts will be glad to advise trade fair visitors on these and other interesting Mesutronic metal detectors and separators and we look forward to many interesting technical discussions about “Metal Detection Made in Germany”.

Precise and reliable Metal detectors from Mesutronic protect the processing machines of the industry giant Stora Enso

Somewhere on a round timber yard in South Germany: a gripper places a tree trunk on a conveyor belt, which guides it through a metal detector. Suddenly an alarm siren sounds and the conveying process is stopped – a piece of metal has been detected. This, or something similar, is the common metal detection process in the wood industry. Possible metal contaminants often have to be intercepted before cutting in the sawmill in order to protect the expensive saw blades. But what about the protection of machines in the further processing? The Finnish industry giant in the wood segment, Stora Enso, has relied for years on the proven technology from Mesutronic GmbH from Kirchberg im Wald to protect its production machines. But first things first!

Detection of larger metal parts to protect your production.

Detection of larger metal parts to protect your production.

The Stora Enso company can look back on a hundred years of history and is today one of the largest timber processors worldwide. Its five business divisions generate an annual turnover of around 10.3 billion euros with a total of 28,000 employees. The ‘Wood Products’ segment is one the most successful in the company and is really impressive with a sawing capacity of 5.6 million cubic metres. Part of the Stora Enso family is located in the picturesque town of Pfarrkirchen in Lower Bavaria. This location mainly produces KVH® solid structural timber and Duobalken/Triobalken® beams for the construction industry. Naturally the production also generates waste – the so-called industrial wood residues. These are woods generated as by-products, residues or waste in the woodworking industry. Of course the industrial wood residues are not simply disposed of in the Pfarrkirchen works, but are recycled in a sustainable and environmentally friendly manner. First of all the wood is collected in silos and prepared for the further processing. The first metal detector from Mesutronic is already installed before the collecting containers; it acts, so to speak, as the entrance inspection. It is mounted under a vibrating channel and has the task of detecting larger metal parts that could damage the downstream shredder. And it has been successfully doing just that for over ten years now. After the silo there are in principle two possibilities for further utilisation. Firstly, combustion in the in-house heating plant or, secondly, processing into wood pellets. In the latter case, further processing steps follow that require a great deal of care. The raw materials are ground further in a grinder and fed to the pelletizing plant via a piping system. Then, under high pressure, the material is pressed through a steel die, which has holes in the desired pellet size.

The high pressure heats up the wood and causes the lignin in the material to liquefy, so that it can act as a binding agent. In order to protect the die, a metal detector with a separation system must be placed before the pelletizing plant. Stora-Enso in Pfarrkirchen thereby utilises a solution from the textile industry. The Metron 05 PowerLine metal detector is combined with the high-performance Texreject separation system to form a highly efficient complete system. The metal detector is mounted in a piping system and checks the ground wood before the separating diverter. If a metal contaminant is detected, the detector sends a signal to the Texreject, which then separates out the contaminated material. The separation of the small fragments of wood in a controlled manner is both a big challenge and new territory in the wood industry. The separator from Mesutronic provides all the conditions required to overcome this difficulty. Thanks to the pneumatic diameter of 500 mm it can cope even with enormous streams of material without problems. With its fast flap opening time of 0.16 s it separates contaminants from the product stream reliably and without interruptions in production and diverts them into a bad material container. Contaminations that occur are, for example, the steel wedge hammers used for marking solid structural timber. These are so hard that they would irreparably damage the pellet die and bring production to a standstill. The reliable and low-maintenance metal detectors and separators from Mesutronic have been reliably preventing that for many years.
