What does a concrete mixer do?

Concrete mixer (commonly known as cement mixer) is a construction tool that mixes cement, gravel aggregate and water to make concrete mixture. The electric concrete mixer machine is mainly composed of mixing drum, feeding and unloading mechanism, water supply system, prime mover, transmission mechanism, frame and supporting device. The transmission mechanism adopted by the concrete mixer can effectively overcome the slipping phenomenon between the supporting roller and the mixer drum in rainy and foggy weather. The structural design of the electric concrete mixer machine directly affects the adaptability to various concretes and the strength and wear resistance of various materials. Therefore, in the structural design of the electric concrete mixer, it is necessary to fully absorb and learn from the advantages of various mixers to continuously improve the performance and use of the concrete mixer, and enhance the mixing capacity of the concrete mixer machine. For smaller projects, mobile concrete mixers are usually used. Its advantage is that concrete can be manufactured on the construction site, allowing workers to have enough time to use the concrete before it hardens.

What are the advantages of concrete mixer?

• Make the composition of the composition uniform macroscopically and microscopically.
• Destroy the agglomeration of cement particles and promote the development of dispersion.
• Destroy the initial hydrate film coating on the surface of cement particles.
• Promote collision and friction between material particles, reduce the impact of dust film.
• Increase the number of times each unit body of the mixture participates in the movement and the cross frequency of the movement trajectory, and accelerate the homogenization.

Various types of concrete mixers

1. According to the mixing principle

• Self-falling concrete mixer: There are radially arranged mixing blades on the inner wall of the mixing drum of the self-falling concrete mixer. When working, the mixing drum revolves around its horizontal axis, and the materials added to the mixing drum are lifted to a certain height by the blades, and then fall under its own weight, so that the repeated movement can achieve the effect of uniform mixing. The structure of the self-falling concrete mixer is simple, generally mixing plastic concrete.
• Compulsory mixer: The rotating shaft arm frame of the compulsory concrete mixer is equipped with mixing blades, and the materials in the mixing drum are added to form a cross flow under the strong stirring of the mixing blades. This mixing method is far stronger than the self-falling mixing method, and is mainly suitable for mixing dry hard concrete.

2. According to the nature of work

• Continuous working mixer: It is equipped with spiral mixing blades. Various materials are continuously weighed according to the mixing ratio and then sent into the mixer. The mixed concrete is continuously discharged from the discharge end. This kind of electric concrete mixer machine has short mixing time, high productivity, and its development is eye-catching.
• Periodic working mixer.

3. According to the shape of the mixing tank

• Drum type.
• Cone type.
• Disc type.

4. According to the working transmission mode

• Friction transmission, commonly known as friction mixer.
• Gear drive, commonly known as ring gear mixer.

In addition, the electric concrete mixer machine is also divided into split drum type and round trough type (that is, horizontal shaft type) mixer.

How to operate concrete mixers safely?

1. Empty test should be carried out before mixing.
2. Adjust the timing of the time relay according to the stirring time, pay attention to the adjustment in the case of power failure.
3. Moisten the mixing drum, blades and ground with water.
4. If electrical or mechanical failure occurs during the process, part of the mixture should be unloaded to reduce the load, and then turn on the machine after troubleshooting.
5. When operating and using, check frequently to prevent safety accidents such as electric shock and mechanical injury.
6. After use, turn off the power, clean up the mixing drum and the site, and clean it up.

How to install electric mini concrete mixer machine?

1. Install handrail bracket and mounting brackets (Note: When u-shaped wire is fixed, the higher the inclination if the handrail bracket moved up.)

2. Install walking wheel shafts and fixed (Note: Pay attention to usage of U Wire. And the walking wheel is fixed with a clamping wire.)

3. Install support wheels bracket and support wheels (Note: Do not fix the shaft screw too tight, so that the roller can be normal rotation.)

4. Install motor shield and motor (Note: The four screws of the motor should be matched with the spring pad and the flat gasket.)

5. Install lower drums and seals (Note: Pay Attention to the hole position when fixing the lower barrel, fix the sealing ring on the upper barrel.)

6. Install drums and mixing blades (Note: The upper and lower drum are in a straight line before fixing. Finally, fix the mixing blades.)
