Concrete mixers are devices or machines widely used in construction, which are used to make the concrete or concrete necessary to carry out the work of the works. If in the past, the mixing of the elements that make up concrete, such as cement, aggregates, and water, was carried out manually, today this task is entrusted to concrete mixers, which mechanize a heavy and laborious process, since the aggregates that They are used to make concrete, they are usually thick and quite heavy.
Where are you going to use it?
There are different types of concrete mixers, as many as needs and specific situations. If we attend to the question of the establishment and position in the works of these mixing machines, we can talk about:
Fixed or semi-fixed concrete mixers that are totally or partially permanently established in the place where the construction is carried out. They can also be located in a strategic position from which several works can be served without being so far away that the concrete is set.
Mobile or portable concrete mixers. They usually have wheels that facilitate their transport to the place where it is necessary to have the concrete mass. The most classic example would be the concrete mixer truck.
Mobile concrete mixers can also be dismountable, which have a series of pieces joined by screws, which makes their storage and transport much easier.
There are other folding models that take up less space and are comfortable in certain circumstances since the legs and the frame can be folded for storage until the moment they are to be used.
What motor do you need?
But, perhaps the most important classification of types of concrete mixers is the one that refers to the procedure by which the tank is moved. Within this, we differentiate between:
Electric concrete mixers. They are equipped with a motor of this type, which makes it necessary to have a power outlet or an electric generator nearby that is capable of powering it.
Engine concrete mixers. In this category, there are concrete mixers with a diesel engine, which run on diesel, which allows greater power, or with a gasoline engine, the most common model due to its high performance.
Before choosing between different types of concrete mixers, we have to bear in mind our true needs. Thus, electric concrete mixers are suitable for simpler jobs, for example, DIY. Their capacity is usually lower and they do more odd jobs.
concrete mixers, whether diesel or gasoline, can be used for more professional jobs because they provide more power and are more robust. In addition, they are endowed with greater autonomy on-site, since the existence of a power outlet is not essential.
Their power makes them useful for all kinds of uses, in larger jobs, and they can be operated anywhere with sufficient ventilation. One drawback of this type of concrete mixer, in cold weather, is that it requires a prior engine warm-up before use to achieve better performance.
What size to choose?
On the other hand, the size of the tank is also important, which will determine the type of work that the concrete mixer can do. The tank is the container installed on the rotating drum of the machine.
It must be taken into account that the capacity of the tank will always be greater than the total volume that the final mix will reach, which means that the amount of resulting mass or cement will always be less.
Precautions when using a concrete mixer
In any of the cases, the person who is going to use the concrete mixers must observe a series of precautions, among which is to follow the instructions provided by each manufacturer to the letter and to know clearly how it works.
Even if it is occasional work or DIY concrete mixers and other light models, it is highly recommended to always wear the right clothing, as a safety and protection measure. This includes glasses to protect the eyes, gloves, and rubber boots that isolate from any shock and clothing that is not too loose or with very protruding parts, to avoid the possibility of being caught by any of the moving elements of the machine.
If the concrete mixer is electric, the connection to the power outlet must be secured with a moisture-proof hose and the correct operation of the earth connection must be periodically verified to avoid accidents.
