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

Overloading causes the mixer shaft to stop rotating. Simply adjust the feed quantity, unload the excess material, and reduce the load on the mixer shaft.

Section 2: There are large foreign objects between the agitator blades or side blades and the inner wall of the tank.

This situation can also cause the side-entry mixer's shaft to stop turning or turn slowly. A large foreign object between the mixing blades or side blades and the tank inner wall can also lead to the shaft's stoppage. The foreign object gets trapped due to the excessive gap between the concrete mixer's mixing blades or side blades and the tank inner wall.

When the side blade gets stuck with material against the inner wall, a sharp, piercing noise is often heard before the agitator shaft stops rotating. In such cases, the machine should be immediately shut down for inspection, with foreign objects manually removed, and the gap between the side-in agitator blades or the side blade and the tank inner wall re-adjusted.

Section three: Side-entry mixer motor drive belt too loose

Loose drive belts on side-entry mixers can cause the mixer shaft to rotate slowly or stop altogether. If the drive belts are too loose, insufficient power is transmitted. In such cases, simply stopping the machine and adjusting the tension of the side-entry mixer's drive belt is sufficient.

So, if you encounter issues with a side-entry mixer running slow, generally following the above methods to resolve the problem is correct.
