The mixing arm drives the mixing blade to force the mixing of the material in the tank body, the mixing effect is very strong, and the mixing quality is better.There are two steel bearing protection circles between the mixing arm and shaft.to prevent coarse sand.In the steel circles there is a airway. When certain pressure of air goes though it,a pressure protection mat will be formed between the interface of the mixing arm and shaft to prevent water and mud from close to shaft head and prolong the service life of the mixer.
