Forglass has been selected by Stoelzle Glass Group to design, fabricate and install a cullet handling system at its Köflach plant, Austria.
The challenge presented by the client was to increase the capacity of cullet transport and reduce its overall footprint at the same time.
The Forglass-designed system will handle the unloading of PCR cullet brought in by truck or bucket loader, storing it in three new silos and dosing it directly on to belt conveyors.
The Polish glass technology supplier will also design and construct a steel-framed building for the entire system, which will be attached to the existing batch plant.
The Forglass technology is based on dedicated equipment for unloading the PCR cullet, crushing it to a predetermined size, then transporting it via vibrating chutes and bucket elevators into the silos, designed particularly to handle abrasive materials.
Dosing of the material will be accomplished by belt scales, placed directly under the silos.
The client will enjoy the nearly doubled cullet storage capacity and an increased overall efficiency of the cullet line by 25%.
The compact design of the entire transport system will occupy much less space than the old system, and the batch plant will gain the ability to control cullet size, thanks to a crusher, designed and manufactured by Forglass.
