A concrete mixer (also commonly called a cement mixer) is a device that homogeneously combines cement, aggregate such as sand or gravel, and water to form concrete. A typical concrete mixer uses a revolving drum to mix the components. For smaller volume works portable concrete mixers are often used so that the concrete can be made at the construction site, giving the workers ample time to use the concrete before it hardens. An alternative to a machine is mixing concrete by hand. This is usually done in a wheelbarrow; however, several companies have recently begun to sell modified tarps for this purpose.
The concrete mixer truck is just made up of the second class chassis and cement mixing transporting device,etc. The special devices of the mixer truck are PTO, the front and rear brackets of the mixing drum, reducer, hydraulic system, mixing drum, operation mechanism, cleaning system, etc. the working principal of the mixer truck is using the PTO take the power of the chassis, and also drive the variable stroke pump of the hydraulic system , changing the mechanical energy into hydraulic energy then transfer to the motor, and the motor drive the reducer, the reducer drive the mixing device, then mixing the cement, etc.
