You can try using silicone plastic sorting machine.
Silicone machine is used for solid waste crushed material sorting, screening out silicone, rubber, wood, gum paper and dust from plastic granules and recovering clean plastic.
Silicone machine is based on the differences in the friction coefficient and collision coefficient of the components of the mixed solid waste, when moving on the inclined plane or colliding with the inclined plane bouncing, different movement speeds and bouncing trajectories are generated to achieve the separation of plastics and silicone rubber (that is, the use of elasticity and friction to the discarded plastics in the silica gel, rubber, wood, adhesive paper and dust to separate out of the plastic).
