Recycling never stops: back to full productivity after an overhaul project (video)

Making high-quality raw materials from scrap on a large scale in the best operative and efficient way. This is what Belgian Scrap Terminal (BST)’s core business is all about. Or the “art of recycling” for which the company is known. What happens when it is time to overhaul the metal recycling machines of such scale?

People have always recycled things. It is simply in our nature. Nowadays, it has become a necessity to find smarter ways to handle the re-usage of goods in our modern lives. The family behind Belgian Scrap Terminal knows the recycling business well.

“My grandfather started as a street dealer. In the 70s, he purchased his first machine for the Willebroek site in order to step deeper into the scrap business,” says Patrick Craenhals, owner and CEO of BST.

The family has continued growing and developing the company. In 1970, they began recycling discarded consumer goods and industrial scrap, which is made into reusable raw materials for customers in steel and non-ferrous industries. From its own terminal in the port of Antwerp (Kallo), BST exports recycled materials to steel producing customers located around the world.

BST’s relationship with Metso also has a long history. Metso Lindemann has been a trusted brand for BST for some time, and BST has cooperated with its experts to gain access to their deep industry knowledge. Metso’s Metal Recycling business line offers a wide range of solutions for the fragmentation, compaction and separation of virtually every type of metal scrap. The focus has always been on designing and building first-class equipment that gives customers the highest availability and minimizes downtime. The service portfolio covers the entire life cycle of a plant.

Time for an overhaul project 

“We decided, after a good study, that it was time to have a big overhaul maintenance of the 1,250 ton scrap shear, Craenhals says.

The shear had been installed in 1993. Metso’s Andreas Schenzer, Head of Technical Services at Metal Recycling Services, summarizes the situation: “Whenever you destroy metal with other metals, you get wear. Once you refurbish the machinery, it’s like new. And you’re back on track for another 20 years.”

The overhaul project for BST was a combination of three services that Metso provides: the supply of parts, Metso’s experts working onsite, and the usage of Metso’s new repair center in Düsseldorf, Germany. The scope included the repair of the shear piston, stamper piston, press lid, side cylinder, main pusher cylinder and the 16.5 ton blade slide. In practice, this meant keeping the “old lady running” with state-of-the-art technology based on the latest industry trends.  

Benefits of full service repair center

For the BST shear overhaul, the Düsseldorf repair center played a key role alongside the work going on onsite. The Metso repair center provides full service with standard warranty, from the repairs of parts and components, such as shredder rotors, blade slides and hydraulic cylinders, to complete machinery overhaul projects.

For BST, the parts were brought to the Düsseldorf center for Metso’s technicians to work on.

“The customer would come to carry out quality inspections and then take the parts back to the site. From there, our people onsite would make the assembly,” Metso’s Schenzer describes the process.

The repair center ensures in-time delivery, quality control and assurance along with the benefit of being close to the customer.

“We follow the same high quality standards with our repairs and refurbishments as we do when manufacturing new equipment,” highlights Marcelo Farah, Vice President, Metal Recycling Services at Metso.

An evaluation of a components repair needs can be provided within a few days after receiving it in Düsseldorf.

Recycling continues – always improving

“It will take us 2 ½ months to do all the necessary repairs and changes of blades and the old parts of the construction. We are very happy to have them here and to do a very good job”, tells BST’s Craenhals about the work with Metso’s specialists.

“And it is our target that we can meet the highest possible percentage in recycling and to recover all precious metals. Getting more out of processes, while putting less in, is critical in today’s world of metal scrap processing,” says Schenzer. He adds with content: “Recycling never stops.”
