Types of concrete mixers
Today, there is a huge selection of mixers on the market. They vary in price, volume of mixing drums, the device itself. Among such variety it is not easy to choose exactly what you need. This article will tell you about which concrete mixer to choose.
The main types of concrete mixers are gravity( free) and forced action. In the gravitational mixer, the mixing process is performed by a mixing pear, while in the forced mixer the blades rotate in a stationary drum. Practice shows that the forced method of preparing mixtures is better.
Mixing pear - basic mixer tool
Before you select the concrete mixer correctly, you need to know how they differ and are characterized. Probably, the main characteristic of any mixer is the volume of the mixing pear, because the quantity of the mixture produced directly depends on it in one approach. According to this indicator, they are very diverse: from 25 to 3000 liters. Concrete mixers up to 100 liters are used for small-scale chores, as well as for the construction of small objects, such as a garage or cellar. Their dignity is compactness and lightness.
More extensive units can already be used for the construction of country houses or other buildings. Giants for 3000 liters are used in concrete mixing plants and large construction sites.
The choice of concrete mixer will also depend on the class of the machine. On this basis, they can be classified into professional and non-professional. When buying this device, the closest attention should be paid to the mixing pear, because this is the most amortizable element of the concrete mixer.
They can be manufactured under hydraulic press or on rollers. Pears made on the press are smooth and have practically no welds, but their walls are rather thin. The drums produced on rolls can be immediately distinguished by the presence of welded seams. These tanks are not very aesthetic, but more durable and strong, because the walls they have from a thick metal.
Technical characteristics - what to consider when choosing?
Which concrete mixer is best for one or another purpose, will depend on the intensity of its operation. When heavy loads and large volumes of produced mixtures, of course, it is better to use a professional one. Such devices can work long enough without interruptions. For dacha construction suitable non-professional concrete mixers. These units will cope with the task at hand, while they are inexpensive.
Concrete mixers can be different in design. There are two basic types of structures: corona and gearbox. Venular units are simple, apparently, therefore, are popular with manufacturers. The reducer type of construction is reliable and durable.
Another important factor in choosing a mixer is the engine power. A good engine is the key to a successful and continuous operation of the device. It will cope with the voltage spikes in the network and will allow the concrete mixer to be used at 100% of its capacity.
The color of the concrete mixer is also important. According to SNIP, any rotating mechanism should have a bright red or orange color. Given the above factors that affect the choice of concrete mixer, you can make a kind of rating of concrete mixers, the first lines of which will occupy the machines, which combine power, reliability and low price.
