如何将塑料变成颗粒？
塑料制品在我们的日常生活中发挥着重要作用，但废弃的塑料制品也给环境带来了巨大的压力。为了解决这个问题，塑料颗粒的回收利用就显得尤为重要。今天，我们将向您展示废旧塑料如何回收并转化为塑料颗粒。主要工艺是将废旧塑料粉碎成碎片，然后熔化。
Shredding
Waste plastics are first sent to the plastic shredder for crushing, breaking large plastic materials into small particles for subsequent processing.
Washing
The crushed plastic pellets will be sent to the washing equipment for cleaning to remove the surface dirt and impurities to ensure the purity of the pellets.
Melting and pelletizing
The cleaned plastic pellets are fed into the plastic pelletizing machine where they are heated and melted into liquid plastic. This process can be accomplished by heat and friction.
Cooling and Cutting
将熔化的塑料挤出成细丝，在水槽中冷却，然后通过切割机切成小塑料颗粒，形成塑料颗粒。这些颗粒可以再次用来制造新的塑料制品。
