How to choose a concrete mixer?

2025-09-28

A concrete mixer, as the name suggests, is essentially an essential concrete mixing device for a concrete mixing plant. Common types of concrete mixers include forced mixers and free-fall mixers. Concrete mixers are widely used in large-scale construction projects, such as roads, bridges, and water conservancy projects. They are highly efficient equipment. Today, we'll take a closer look at concrete mixers.

Concrete mixers play a crucial role in a concrete mixing plant. They consume a significant amount of equipment, so it's important to be familiar with their operation. Next, we'll detail the operating procedures and precautions.

Planetary Mixer

1. Using a Forced Internal Mixer

Before using the mixer, flush the cavity with a small amount of mortar and scrape off the mortar. Otherwise, any cement mortar stuck to the drum wall will drain away. Weigh the various concrete raw materials as needed, then add gravel, sand, and cement to the concrete mixer in that order. Start the mixer slowly and evenly, adding water to ensure a smooth mixing process. The feeding time should be kept within two minutes. After adding water, continue stirring for about two minutes. Pour the mixture onto a steel plate and stir manually for about one to two minutes to ensure it is thoroughly mixed. Finally, turn off the power and clean the equipment.

II. Precautions During Mixer Operation

1. The mixer must be supported by a stand and placed in a secure location.

2. Before using the mixer, inspect it to ensure that the equipment's controls and components are in good condition before operating it. The mixer drum must be free of foreign matter, as this will affect subsequent mixing.

3. For safety reasons, personnel are strictly prohibited from passing or remaining under the hopper while the mixer is rising into the hopper. Tools must not be inserted into the mixing drum while the mixer is running.

4. If on-site maintenance is required, the mixer hopper must be secured and the power must be turned off before repairs can be performed. If access to the mixing drum is required, someone must be present outside for supervision.

Currently, there are many different types of concrete mixers, making it important to choose the right one.

III. How should one choose a standard concrete mixer?

1. Cost-effectiveness of the equipment;

2. Production scale: Select a concrete mixer based on annual output;

3. Determine the production capacity of the concrete mixing equipment based on the size of the construction site;

4. To produce high-quality concrete, you must choose reliable production equipment;

5. Consider the equipment's advancement, reliability, quality, and versatility;

6. Pursuing comprehensive equipment technical performance is unwise and will lead to unnecessary investment. However, pursuing low investment while compromising equipment technical performance will increase operating costs, which is also undesirable.

7. Forced concrete mixers offer excellent mixing quality, strong overload capacity, zero segregation during discharge, high production efficiency, and are suitable for mixing concrete with a variety of performance requirements. Currently, forced mixers are widely used in commercial concrete mixing equipment.

If you're still confused after reading this, or find it too complex, consider choosing a Zenith planetary concrete mixer. This model is driven by a mixing motor and a planetary gear reducer. The reducer housing rotates via internal gears, and one or two planetary arms on the reducer rotate independently, enabling the mixer to rotate 360° without blind spots, quickly and efficiently mixing materials. It can be used with a variety of fixtures and materials to meet the needs of a wide range of mixing materials.

The following is a comparison of our product with other common products:

Comparison Aspects	Planetary Concrete Mixer	Regular Mixer
Drive and Mixing Method	The planetary mixer is driven by a stirrer motor and a planetary gear reducer. The reducer housing is rotated by internal gears. 1-2 sets of planetary arms on the reducer rotate on their own, ensuring a 360° rotation with no dead spots, achieving rapid and efficient mixing of materials.	Traditional mixers typically use a single or multi-shaft mixing method, which may result in mixing dead zones, leading to poor homogeneity.
Mixing Uniformity	Mixing uniformity can reach over 90%, ensuring fast and efficient mixing and meeting a wide range of applications.	Mixing uniformity is relatively lower, potentially affecting the performance and quality of the mixture.
Production Efficiency	The planetary mixer has a short mixing cycle and high production efficiency, with a wide theoretical production rate, suitable for both laboratory and large-scale production lines.	Traditional mixers have a longer mixing cycle, resulting in lower production efficiency.
Discharge Cleanliness	The planetary mixer discharges cleanly, with no residual material at the bottom of the drum, ensuring each processing session results in a clean and tidy mixture.	Traditional mixers may have residual material at the bottom, requiring additional cleaning procedures.
Scope of Application	Can be used with various fixtures and materials, meeting a wide range of mixing material needs, applicable to various industries and purposes.	Features are more limited and may not be able to meet the diverse material processing needs.
Mixing Power	Mixing power can be as high as 75 kilowatts (e.g., the MMP2000 model), ensuring effective handling of multiple types of aggregates.	Lower power, which may be limited when handling large-scale or special materials.
Theoretical Service Life	The theoretical service life is 10, 000 or 20, 000 batches, enabling long-term continuous operation with relatively low maintenance needs.	The theoretical service life may vary depending on specific design, with potentially higher maintenance costs.
Size and Load Capacity	Planetary mixers have a wide range of capacities, from 550 liters of feed capacity for the MMP375 to 3000 liters for the MMP2000, offering strong load capacity.	May lack the capacity to handle larger mixing needs.
Material Adaptability	Specially designed mixing blades and adjustable speed features can adapt to materials with different viscosities and flow properties, significantly increasing its practicality and adaptability.	May have limited performance when dealing with special materials.
