The impeller shaft of the side-entry mixer can become slow to rotate when it exceeds the normal working load, and if the load is too heavy, it may cause the impeller shaft to stop rotating.

Overloading caused the mixing shaft to stop rotating. Simply adjust the feed amount, discharge the excess material, and reduce the load on the mixing shaft.

Two: There are large foreign objects between the agitator blades or side blades and the interior wall of the tank.

This situation can also cause the side-entry mixer's shaft to stop turning or turn slowly. A significant foreign object between the mixing blades or side blades and the tank inner wall can also lead to the shaft stopping, which is due to the excessive gap between the concrete mixer's mixing blades or side blades and the tank inner wall.

When side vanes get caught on material against the inner wall, a sharp, piercing sound is often heard before the agitator shaft stops rotating. In such cases, the machine should be immediately shut down for inspection, and foreign objects should be manually removed. The side-entry agitator vanes or the gap between the side vanes and the inner wall of the tank should be re-adjusted.

Section three: Sideloaded mixer motor drive belt too loose

Improperly loose drive belts on the side-entry mixer motor can lead to the slow or complete stop of the mixer shaft rotation. If the drive belts are too loose, it results in insufficient power transmission. To resolve this issue, simply stop the machine and adjust the tension of the side-entry mixer motor's drive belt.

So, if you encounter issues with a side-entry mixer running slow, it's generally correct to address the problem using the methods mentioned above.
