[0002] Polystyrene foam board is EPS board, which is a polystyrene foam plastic board with a closed-cell structure made by pre-foaming expandable polystyrene beads and then heating and molding them in a mold. It has the advantages of light weight, low price, low thermal conductivity, low water absorption, good electrical insulation, sound insulation, shockproof, moisture-proof, and simple molding process. Therefore, it is widely used as thermal insulation, sound insulation, and shock-resistant materials for construction, ships, automobiles, trains, refrigeration, and freezing. In the process of recycling polystyrene foam board waste, a polystyrene foam board crushing and recycling device is needed.
