The new STADLER PX acceleration conveyor meets the demand for higher throughput in sensor-based automatic sorting, which can operate at higher working speeds. To achieve the desired result, STADLER has integrated the best features of its popular BB and DB conveyors, and has taken the opportunity to introduce a host of improvements. They include a new air stabilizer, which ensures consistent sorting quality at faster speeds with light materials, resulting in excellent purity of the output.
“At STADLER we are always very alert to how our customers’ needs evolve. We are constantly looking at ways to address these changes by improving our products or developing new ones,” explains Corinna König, Team Leader Product Management. “We found that we were increasingly combining our BB and DB conveyors in customers’ projects to achieve the desired result, so we developed the PX, which combines the best features of each into one conveyor. This means that our customers now have only one machine to operate and maintain, simplifying their operation and reducing their costs. And we went further, because we significantly increased the belt speed, even with light materials, so they can increase their throughput with just the one machine – and they can count on consistently high purity levels.”
Italian company Irigom Srl has installed 6 PX conveyors at its SSF (Secondary Solid Fuel) plant, which is designed to separate and recover all valuable material from the incoming plastic waste. The recovered PET, PE-LD and PP is sent to a recycling facility, while the residue is used to produce high-quality SSF. The conveyors have been operating for 3 months, sorting PET, PE-LD and PP materials for recovery, metals, and PVC which is removed from the process. Stefano Montanaro, CEO of Irigom, is impressed with the results: “The PX is performing very well. The fast speed up to 4.5 m/s is allowing us to significantly increase the total material input, while maintaining a very high-quality material in the output.”
