concrete cement mixers working principle

The working principle of a concrete mixer is to drive the mixing drum to rotate through an electric motor and a reducer, push the mixture out of the mixing drum with the help of a hydraulic system, and perform operations such as feeding and unloading through a feeding and discharging device.

The concrete mixer is mainly composed of an electric motor, a reducer, a hydraulic system, a mixing drum, a feeding and discharging device, and other parts. When the concrete mixer starts working, the raw materials are loaded into the mixing drum. The motor rotates the reducer, and the reducer transmits power to the mixing drum, causing the mixing drum to start rotating. At the same time, the hydraulic system provides pressure to push the mixture out of the mixing drum and output it to the construction site where it needs to be poured with the help of a discharging device. During the mixing process, operations such as feeding, mixing, and unloading of the mixed materials are also required. When mixing materials in the mixing drum, the mixing plate moves along the tracks set at various angles, so that the mixed materials are quickly and evenly mixed in the mixing drum. Then, the discharging device is opened to discharge the mixture and transport it to the place where it needs to be used, such as a construction site, through a conveying pipeline.

The design of concrete mixer aims to make the motion tracks of the components of the mixture in the mixing process intersect and cross each other in the relative convergence area as much as possible, produce mutual collision to the maximum extent in the entire volume of the mixture, and increase the number of times each component volume participates in the motion and the crossing frequency of the motion tracks as much as possible, so as to create the most favorable conditions for the concrete mixture to achieve microscopic and macroscopic homogeneity. The purpose of mixing is to make the components uniform at the microscopic and macroscopic level, destroy the aggregation phenomenon of cement particles, and promote the development of dispersion phenomenon; destroy the initial hydrate film coating layer on the surface of cement particles; promote the collision and collision between material particles and reduce the influence of dust film.
