ways to calculate concrete mixer drum rotation

Design and Calculation of a Concrete Mixer (100 kg) – IJERT

Once the materials are sufficiently mixed thee rotation of the drum is reversed and the blade arrangement pushes the concrete through to the discharge end of the mixer. Commonly self-loading, reversible mixers are mid-size to large-size units mounted on a two-or four-wheeled trailer for transportation between sites.

Design and Calculation of a Concrete Mixer (100 kg)

The drum on a reversible mixer has one horizontal axis around which it rotates. In mixing position, the drum rotates in one direction; the blades mix by lifting and dropping the materials during each rotation.

Oct 31, 2012 · you must calculate for the 1500liter means 1.5 cubic meter capacity. Because after mixing 1.5 cm raw materials compacts up to 1 cm. So calculate the torque required to rotate or move the 2400kg x1.5 = 3600kg. So required torque to move 3600kg @ 1m( depends on your arm length) = 36000Nm. So you will require 36000Nm capacity gearbox.

Sand = 35×2 = 70 liters. Aggregate = 35×4 = 140 liters. Concrete yield in slurry state = 2/3 (cement+Sand+Aggregate) = 2/3 ( 35+70+140) = 170 liters. 10% excess = 170 + (170x (10/100) = 187 liters. Therefore, volume of concrete mixer should be at least 200 liter if you want to use one whole bag of cement.

Study on the dynamic performance of concrete mixer’s mixing drum

distribution shape of the concrete changes with the rotation of the rotating drum. The shape of the concrete on a cross section should be as that shown in Fig. 2. Rotating speed can not be too high, otherwise, the concrete will form a ring distribution in the rotary drum, and can not form an effective mixing.
