Description

Technical Field

[0001] The utility model belongs to the technical field of rubber processing, and in particular relates to a mixer for rubber mixing. Background Art

[0002] Rubber refers to a highly elastic polymer material with reversible deformation. It is elastic at room temperature and can produce large deformation under a small external force. It can return to its original shape after the external force is removed. Mixing is the process of mixing raw rubber or plasticized raw rubber with compounding agents into mixed rubber using a rubber mixer. It is the most important production process in rubber processing.
