The EPS Compactor can also understand the polystyrene foam reducing machine. The principle is to compress the EPS foam into pieces by a screw compression mechanism. In use, the operator simply puts the foam block into the hopper, and the machine has a tearing mechanism to break the foam block, and then the screw mechanism extrudes the small piece of EPS foam into a compressed block having a square cross section. The EPS Compactor can be used in several common forms such as cold press, hot press, hot melt, and hydraulic pressure.
There is a pressure regulating device at the front end of the compression section to adjust the compression ratio. According to the characteristics of the raw materials, the compression ratio can reach 30~40 times, so as to reduce the EPS volume, so as to facilitate long-distance transportation and reduce storage and transportation costs.
The cold-pressed EPS briquetting machine directly pushes the EPS foam by using a screw without heating. Hasswell introduced its smallest screw compactor at the 2007 K show in Germany, model cp-130. The machine's ability to process EPS is 13.6~18.4kg/h, the density of the final product will increase by 40 times, and the latest compaction density control can even reach 320.5kg/m3.
The hot pressing type briquetting machine is mainly used for pressing PU material. The difference between the hot pressing type briquetting machine and the cold pressing type briquetting machine is that a heater is added in the pressing section of the cold pressing type briquetting machine to pass the The material in the heating section is extruded in a semi-melt state by the discharge port. Heger exhibited this type of briquetting machine at the 2007 K show in Germany. This type of machine has a high extrusion density and can be achieved in unit yield. More than 500KG per cubic.
The compactor is mainly used to compact product scraps for large Styrofoam Compactor. There are also some other types of briquetting machines. The above models are the most used and the most common.
