After the raw material formula according to the specific technical requirements is mixed by an internal mixer, the raw materials which are originally colloid, particles and powder and the batch materials are fused and melted into a micelle. But the dispersion degree between various batch materials and rubber (plastic) in the raw materials is low, and only the common dispersion degree is achieved. In order to fully disperse various components in the micelle into sheet materials or granular materials which can enter a forming process, the sheet materials or the granular materials are subjected to thick-passing, thin-passing, triangular bag making, thick-thin kneading and refining by an open mill according to the industrial terminology, and then the sheet materials or the granular materials are prepared into rubber particles by a sheet discharging machine or a granulating machine. These procedures have traditionally been manually operated both on stand-alone machines and from machine to machine.
