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.

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.
