The silo for drying expanded polystyrene of various volumes is designed to dry expanded polystyrene granules after the foaming procedure. It consists of a telescopic metal frame, which allows you to adjust the height and volume of the silo, as well as a mesh insert with a cell of 1-2 mm. In the silo, the foamed granules are silted to stabilize the pressure inside the granules and are then used in the production of polystyrene concrete or foam plastic.
