The M350 two-shaft shredder is said to be the perfect solution whenever a single-shaft shredder is not powerful enough to break down larger quantities of chips or even chips with large cross sections. According to Erdwich, a single-shaft shredder often isn’t powerful enough to achieve the desired result - especially when it comes to chips with special geometries. Instead, it recommends two-shaft machines, which are reportedly far better equipped to handle continuous, large-volume throughput rates - sometimes shredding as much as 4,000 kg of material per hour.
Shredding is a relatively straightforward process: The material in question first gets caught in the hooks of the blades. It is then pulled mercilessly into the system and shredded between the blades of the two counter-rotating shafts. Whether it's special waste, WEEE, metal shavings, electronic waste or bulky waste - even the most durable materials don't stand a chance against such a powerful pair of shafts, no matter the volume. In fact, as Erdwich points out, even materials that are fibrous, moist, heat-sensitive, elastic or very tough can be shredded with ease. What's more, these slow-running two-shaft shredders have been designed to keep both noise and dust to a minimum. Some of the stand-out technical features of these machines include a robust rotary shear cutting system, individually replaceable blade discs, various blade widths and shapes, bulkhead seals to protect the shaft bearing, mechanical or hydraulic drive concepts and a PLC unit with automated reverse and power down.
