Cullet handling system design improvements
Stoelzle Glass Group has turned to technology supplier Forglass to design, fabricate and install a system for handling cullet at the group’s Köflach plant in Austria. The challenge is to increase the capacity of cullet transport, while also reducing its overall footprint.
The Forglass system is designed to handle the unloading of PCR cullet brought in by truck or bucket loader, storing it in three silos and dosing it directly onto belt conveyors.
Poland’s Forglass will also design and construct a steel-framed building for the entire system, which will be attached to the existing batch plant.
The proven technology provided is based on dedicated equipment for unloading the PCR cullet, crushing it to a predetermined size, before transporting it via vibrating chutes and bucket elevators into the silos, which have been specially designed to handle abrasive materials. Dosing of the material will be accomplished by belt scales, placed directly under the silos.
On completion, cullet storage capacity will be nearly doubled and the overall efficiency of the cullet line will be increased by some 25%.
The compact design of the entire transport system will occupy significantly less space than the old system and the batch plant will gain the ability to control cullet size, thanks to the new crusher, designed and manufactured by Forglass.
