After the crusher refines and mixes the materials, it conducts heat melting treatment on the rubber products, and then through the repeated rolling of the pressure rollers, the fragmented materials are formed into complete rubber sheets for other uses.

[0003] However, the previous open mixing devices required manual cutting of the rubber sheets with a spatula, taking out the refined rubber sheets or putting them back into the pressure rollers for continued rolling. After completion, if there were still impurities remaining on the surface of the pressure rollers, manual cleaning was required, which was time-consuming and laborious. If the cleaning was incomplete, it was easy to mix into the next batch of rubber products.
