The pre-expansion machine is a crucial link in the production process of EPS packaging products and EPS insulation boards. For a good pre-expansion machine, if it can produce a large number of foamed particles with uniform specific gravity per unit time, it will be convenient. It can greatly save the cost of raw materials and bring greater profits to users. In order to shorten production time, aging time, reduce steam consumption, and produce high-quality products, the selection of pre-expander must be studied carefully. Arguably, this is the most important part of overall project management.
●Using the bottom discharge method, the temperature difference of the foamed particles can be controlled, and the impact on the environment can be minimized
●A vibration sensor is used to precisely control the foaming specific gravity, and the deviation of the foaming specific gravity is kept at a minimum
The fluidized bed plate adopts punching structure, which can effectively improve the drying effect and shorten the curing time
●Scientific and reasonable air supply system can effectively improve the transmission speed
●Scientific and reasonable pipeline design can effectively reduce energy consumption
●Humanized structural design, easy maintenance
The tank body and head are made of high-quality stainless steel before leaving the factory, and the upper and lower heads are assembled with the tank body to ensure internal dimensional accuracy and reduce the probability of failure
●The automatic control system can record the production status and production volume of the equipment in real time
