Metso showcases shredder design for quick cutting table replacement

Metso Waste Recycling, Helsinki, Finland, has released a new video demonstrating how a complete cutting table replacement on a M&J PreShredder can be performed in less than 100 minutes.

The M&J PreShredder Series features an open cutting table, with bolts and bearings mounted away from the cutting area. This design allows for easy access and maintenance to reduce downtime, the company says. 

According to Metso, the whole operation can be carried out using a smaller crane because the cutting table and hopper can easily be disassembled. After that, only eight bolts between the table and the frame of the shredder need to be loosened before the table can be removed for service or replacement. Furthermore, the bolts have been positioned in such a way that they are not stressed during operation, which makes them easy to loosen. 

"A big advantage of this clever design is that it provides for both better HSE and plant availability, as welding operations can take place in a much more convenient and efficient working environment,” says Morten Kiil Rasmussen, commercial director for Metso Waste Recycling. “The video is impressive to watch because it shows how effective workflows can be when engineers carefully consider the process from the beginning."
