[0002] In modern industrial production, mixers have been widely used in many fields, such as chemical, pharmaceutical, food and environmental protection. In the chemical industry, mixers are used to evenly mix solid materials such as granules, powders and pigments to improve mixing efficiency and product quality. In pharmaceutical processes, mixers are used to evenly mix various pharmaceutical powders to improve pharmaceutical production efficiency and quality. At the same time, mixers also play an important role in the environmental protection industry. The working principle of a rubber mixer is usually to mix the rubber material in a mixing chamber by rotating the agitator. The shape and speed of the agitator can be adjusted according to different mixing requirements to ensure that the rubber material can be fully mixed and evenly mixed.

[0003] When mixing rubber particles, existing mixers have the problem of uneven mixing due to the different sizes of plastic particles.
