The number of beads added to the EPS pre-expander is very accurate each time, the temperature in the machine is displayed at any time, the air intake is uniform, and it is equipped with an air blowing device; in addition, this equipment is equipped with an air-drying, crushing and feeding device, which is also easier to control. The feeding device is generally equipped with a suction filter device, and the powder is not easy to enter the pre-expander, and it is not easy to cause blockage and agglomeration. For raw material beads with low blowing agent (longer storage time) and lighter pre-expanded beads, it can also achieve better results, which is good for cost reduction and adaptability of raw materials. Especially considering the requirements of environmental protection, some manufacturers have implemented the use of raw materials with low foaming agent content (about 3010).
