Precautions of the plastic crushing and washing

There are also some precautions of the plastic crushing and washing, because of the different of plastic type, the processes of the plastic plastic are mainly separated to two types–hard material and soft material. Their washing and cleaning methed and equipment are certainly different.

In one hand, the waste crusher of soft material and hard material are different. Specifically, their blades are different. In the other hand, in the duration of the cleaning, the soft material like plastic woven bags are always floating on the surface of the water, we call them “flaoting material”, the hard plastic like PP flakes always sink under the water, we call them “sinking material”.

一般来说，硬塑料更干净，使用的水更少，因此不需要沉淀池。（沉淀池可以在污水沉淀后抽出并重复使用，这将大大节省用水。）然而，漂浮物非常脏，上面有很多漂浮灰烬，水的需求量很高。

如今，许多国家禁止污水排放，因此需要建造沉淀池和泥浆过滤设备，这样水基本上可以达到国家标准。
