Concrete mixers – basic information
The concrete mixer is one of the essential building tools that can be used in many ways. You can find many varieties of these machines on the market, so it is a good idea to look into their specifications in order to choose a model well suited to our current, and possibly future needs.
What is a concrete mixer used for?
A concrete mixer should be recognized by everyone, and its purpose is also rather well known. They are primarily used to mix cement, water, sand and gravel together to create a single mixture of concrete. Drum-shaped concrete mixers, which are probably the most basic type, are best known and most common. However, this is not the only option among Construction equipment and other types of such equipment can be found.
Features of concrete mixers
- Mixer shape
This is where we separate the pan and drum concrete mixers. Pan mixers are smaller in capacity, so they are especially suitable for renovation work. Drum concrete mixers, on the other hand, are more professional machines.
Here we distinguish between stationary, portable and truck concrete mixers. We should pay the most attention to portable devices – they are the most mobile of the whole group, and by far the lightest and most comfortable to use.
- Working modes
Here we distinguish 2 types of concrete mixers – continuous and Batch mixers. The first type are machines which are most often used in large concrete plants. During the construction of a house, batch concrete mixers are used, whose design allows for frequent switching on and off.
What should you know before purchasing?
When choosing a concrete mixer, several key factors should be considered. One of them is the mixer’s capacity. We choose a concrete mixer depending on the type of project we want to carry out. During bigger projects it is worth considering a much bigger machine. Concrete mixers usually have two capacities – working and total capacity. The working capacity determines the maximum amount of raw material produced, while the total capacity is the maximum capacity of the drum.
We distinguish between drum and pan concrete mixers. Pan concrete mixers are perfect for larger investments. Their main advantage is a larger capacity, which in turn allows to mix much more material in a shorter time. Drum-shaped concrete mixers are characterized by lower capacity and therefore, they are suitable for working on smaller investments.
There are two types of manual tilting are available. The first one uses a round handle and is by far the most popular but requires more force. This option is used in cheaper and less professional concrete mixers. The “crank” tilting is used in larger and more expensive concrete mixers. The tilt is achieved by means of a worm gear, which helps the user. This solution significantly helps during operation and reduces fatigue. It is especially recommended for companies where employees work with this equipment on a daily basis.
- Power supply
Single-phase and three-phase concrete mixers are available on the market as well as those powered by an internal combustion engine. Today’s three-phase designs are much more powerful than single-phase ones, but this comes at the cost of electricity consumption. Single-phase motors will be much more Economical and often Sufficient. An interesting solution is the use of an internal combustion engine, which will work perfectly on construction sites without access to electricity.
