The principle of the foam briquette machine is to compress the foam into blocks using a screw compression mechanism. When in use, the operator only needs to put the foam block into the hopper. There is a shredding mechanism inside the machine to break the foam block, and then the spiral mechanism squeezes the small block of foam into a square compression block. This briquetting machine can use several common forms such as cold pressing, hot pressing, hot melting and hydraulic pressure. There is a pressure adjustment device at the front of the compression section to adjust the compression ratio. According to the characteristics of the raw materials, the compression ratio can reach 30 to 40 times, in order to achieve the purpose of reducing the volume of the foam, and facilitate the long-distance transportation and recycling granulation.
