Concrete Mixer Description

Concrete mixers, double cone mixers of reverse discharge type and tilting discharge type, and drum mixers have come out and developed one after another. The inner wall of the mixing drum of the self falling concrete mixer is provided with mixing blades arranged radially. During operation, the mixing drum rotates around its horizontal axis, adds the materials in the mixing drum, is lifted to the height by the blade, and falls by its own weight. In this way, it moves again and again to achieve the effect of uniform mixing. The structure of self falling concrete mixer is simple, and generally it is mainly used to mix plastic concrete. Concrete mixer is a machine that mixes cement, gravel aggregate and water to make concrete mixture. It is mainly composed of mixing drum, feeding and unloading mechanism, water supply system, prime mover, transmission mechanism, frame and support device. According to the nature of work, it can be divided into intermittent type (batch type) and continuous type; According to the mixing principle, it is divided into self falling type and forced type; According to the installation mode, it is divided into fixed type and mobile type; According to the discharging mode, it is divided into tipping type and non tipping type; According to the structural form of mixing drum, it can be divided into pear type, drum type, double cone, disc vertical shaft type and circular groove horizontal shaft type.

Performance characteristics of concrete mixer:

1.The whole machine has reasonable design, optimized performance and convenient use and maintenance.

2.Convenient operation, fast unloading speed, low energy consumption and low noise.

3.Firm and reliable, long service life, good mixing quality and high efficiency.

Operation steps of concrete mixer:

1.Empty vehicle test run shall be conducted before mixing.

2.Adjust the timing of the time relay according to the mixing time, and pay attention to the adjustment in case of power failure.

3.Wet the mixing drum, blades and site with water.

4.In case of electrical or mechanical failure in the process, part of the mixture shall be unloaded, the load shall be reduced, and the operation can be started after the failure is eliminated.

5.During operation and use, it shall be checked frequently to prevent safety accidents such as electric shock and mechanical injury.

6.After the test, turn off the power, clean the mixing drum and site, and clean up.

Maintenance methods of concrete mixer:

1.Maintain the cleanness of the machine body and remove the dirt and obstacles on the machine body.

2.Check the oil, circuit and control equipment at each lubricating position, and fill lubricating oil as required.

3.before each shift, add water in the mixing drum and idle for 1-2min, and check the reliability of the clutch and braking device at the same time.

4.During the operation of concrete mixer, check whether the noise of motor, reducer and transmission gear is normal and whether the temperature rise is too high,

5.After each shift, the concrete mixer shall be carefully cleaned.

6.To ensure its technical performance, we must pay attention not to shoddy in the maintenance and transformation, and high-quality bearings must be selected.
