Nowadays a glass wool production plant is a major user of recycled glass collected from households and industry. Depending on the availability and price of raw materials versus recycled glass (=cullet) the percentage of cullet can vary a lot. This states requirements for the raw material process, which must be adaptive for rapid changes. Lahti’s flexible recipe handling combined with utilization of accurate dosing belt scale technology allows fast change in the cullet percentage.

Some of the glass wool producers use powder cullet and want to mix cullet with batch in the mixer. For such cases the Lahti mixers with wear resistant liners and mixing tools is a versatile solution.
