The power output of the motor in the mixing equipment is transmitted to the agitator through a stirring shaft, so the stirring shaft must be strong enough.
At the same time, the mixing shaft should not only be connected with the mixer, but also through the shaft sealing device and bearings, couplings and other parts, so the mixing shaft should have a reasonable structure, high machining accuracy and mating tolerances. According to the support situation, the stirring shaft can be divided into cantilever type and single-span type. The cantilever mixing shaft does not set the intermediate bearing or the bottom bearing inside the mixing equipment, so the maintenance and repair is convenient, especially for the biological, food or pharmaceutical mixing equipment with high cleanliness requirements, which reduces the components in the equipment, so it should be selected as a priority.
