Due to sheer volumes required, chipboard panels are among the most popular products in the timber industry. FunderMax, a renowned supplier of wood- based and compact laminate solutions, sets great store in high-quality manufacture. To guarantee this, FunderMax engaged Geroldinger, the Upper Austrian bulk goods specialist.
When it comes to storing difficult bulk goods, building materials manufacturers like FunderMax do well to come to GEROLDINGER. For its chipboard production, FunderMax requires not only that storage facilities are watertight, but also that they are able to handle urea, which is extremely difficult to store.
Since urea is a very hygroscopic bulk good that may form hard crusts because of its capacity to absorb water, it is normally kept in Big Bags or open in warehouses. Because of possible clumping and crust formation, storage in silos is seen as very risky.
“The challenge with this project consisted of controlling the dosing from a large volume of urea down to a very small volume so as to best supply the subsequent process,” is how
