1. The angle of the concrete mixer’s mixing blades should be consistent and the mixing blades can’t be installed inversely.
2. The tilt angle of the mixing blades, too large or too small, can affect the output, so the tilt angle of the blades and the mixing axis is about 70 degrees or 80 degrees.
3. The best angle of the mixing blades is rotated to the upper part and show the mud 20-30mm.
4. We must tighten the installation of mixing blades and we should try to tighten the first nut on the mixing blade.
