Concrete Mixing Methods and Concrete Mixers: State of the Art
When the drum is almost horizontal (inclination ≈ 0°), more energy is provided to the concrete because more concrete is lifted to the full diameter of the drum before dropping. It is during the drop that the concrete is knitted and mixed. Therefore, the higher the drop, the higher the energy imparted to the concrete.
