Types of concrete mixer

When we are going to choose a best concrete mixer for a specific application, we must consider these factors: location site, the amount of concrete needed and the construction schedule.

When we are going to choose a best concrete mixer for a specific application, we must consider these factors: location site, the amount of concrete needed and the construction schedule.There are two main categories of mixer: forced type concrete mixer and self-loading concrete mixer.

(1) Forced type concrete mixer:

Forced type concrete mixer machine can be divided into two types. One is twin shaft concrete mixer and the other is planetary concrete mixer. Their working principles are very similar. They both mix concrete through the rotation of the shaft. Meanwhile the blades attached to the shaft are just like many hands to mix the concrete more homogeneous. The difference between them is that twin shaft concrete mixer has two horizontal shafts while the planetary concrete mixer has one vertical concrete mixer.

Twin shaft concrete mixer:

On the other aspect, the mixing blades of twin horizontal shaft concrete mixer rotate reversely. The blades mix materials repeatedly to make the materials more homogeneous. In this fierce process of rotation, it saved much more time. Therefore, the twin shaft concrete mixer is featured by high efficiency and low time-consuming. This concrete mixer is widely used in the whole world for it is more cost effective.
      
Planetary concrete mixer:

However, for planetary concrete mixer, the two groups of mixing blades mix materials pros and cons. The revolution and rotation speed of the blades give the mixer a high output without causing the segregation of materials with different grain size and weight. The movement of the material inside the trough is smooth and continuous. This concrete mixer is featured by high efficiency, high quality and low maintenance. The concrete it produces is with higher quality. But the price of it is very expensive.
We have listed the advantages and disadvantages of the two kinds of concrete mixer. Just choose a proper one according your own situation. In the next, we will give some advice in the choice of self-loading concrete mixer. Please pay attention on our website. 

     


(2) Self-loading concrete mixer :

Working principles of self-loading concrete mixer :

The working principle of self-loading concrete mixer is quite different from forced type concrete mixer. Many mixing blades are soldered to the wall of the drum. When it starts to work, the drum revolves around horizontal axis. The mixing blades fixed on the drum will lift the materials needed to be mixed to a certain height. Then the materials fall down through the gravity. This concrete mixer operates repeatedly in this way to mix concrete.

Advantages and disadvantages of self-loading concrete mixer :

This kind concrete mixer has simple structures, little wear and it is very easy and convenient to maintain. Furthermore, it adapts materials well and has a relatively small volume. Therefore, it applies to produce plastic concrete and damp-dry rigid concrete. What’s more, this concrete mixer has wheels and it's very convenient to move.

However, Due to it works through the rotation of drum; its stirring intensity, rotating speed and volume has been limited. It leads to lower efficiency than forced type concrete mixer. Therefore, this kind concrete mixer can be used in a relatively small construction site or is for personal use. So, just think over which concrete mixer is more appropriate to you. Choose a best one for your project.
