A regular increase in the scale of construction leads to an increase in demand for various materials necessary for work. Today, private construction is widespread, as people have all the necessary conditions to independently complete this task.
Concrete solutions are very important for the construction of any private construction. Their preparation is a rather difficult and long process of mixing sand and cement with a shovel. To facilitate this task, equipment is often purchased https://walder.ua/ru/ for preparing mortars and concrete.
To prepare stronger concrete, it is necessary to take into account the correct proportions of sand and cement, mixing them until a homogeneous mass is obtained. Then the resulting mass is poured with water and mixed until a homogeneous cement mortar is obtained. There are many mechanical mixers that automatically perform the entire process.
Thus, mechanical equipment for the preparation of various solutions is divided into two large groups:
1. For forced mixing.
2. Gravitational.
The principle of operation of gravity mixers is based on the mixing of components with the help of a rotating drum. Due to the rotation, the components are mixed in free fall. A similar method, as a rule, is used at concrete mixing plants, concrete plants. Such equipment is stationary, as it is not intended for regular movement. These mixers are not suitable for the construction of a private small house, but they are widely used for the construction of large objects.
Equipment for forced mixing includes the following: bsu such as https://walder.ua/ru/production/statsionarnye-bsu/, concrete mixers, concrete mixers and mortar mixers. However, the use of concrete mixers is possible in the construction of multi-storey buildings, and they are also used in concrete mixing plants and factories. For the construction of a low-rise private building, it is best to use the following equipment: mortar, concrete mixer.
Concrete mixers are the most popular, due to their reasonable cost, simple design, as well as ease of use and mobility. Stationary concrete mixers have a volume in the range of 500–600 liters, but there are those that reach 1200–1300 liters. The rotating drum is fully responsible for mixing the solution, as such devices have an electric drive. The concrete mixer is powered by a single-phase 220V network. The power consumed by the equipment depends entirely on the volume and performance. In general, concrete mixers consume power in the range of 800 W, which is much less than the power consumption of an electric kettle.
In order not to fail the electric motor of the concrete mixer, it is necessary to strictly follow the specific rules for operating the device. It should be remembered that materials should be loaded only while the drum is rotating. The equipment should be turned on strictly when the drum is in a vertical position. When uploading materials, it is necessary to observe a certain sequence. Initially, water is poured in, and only then is cement and sand loaded. It is very important to load cement first, and then sand, as the sand will stick to the walls of the drum, which will greatly complicate cleaning.
The solutions are mixed in a concrete mixer for approximately 2 minutes. The equipment works at a speed of up to 20 revolutions per minute, which means that the solution is mixed about 40 times. Such an indicator cannot be achieved by mixing the solution with a shovel. The mixture should also be discharged strictly while the drum is working.
It is necessary to regularly monitor the temperature regime of the engine. Its automatic shutdown may occur due to overheating due to prolonged operation without cooling.
The solvent mixer is another type of equipment for the preparation of various solutions. This device is slightly different from a concrete mixer, but the principle of operation is largely the same. The solvent mixer mixes the components in the finished solution with the help of vertical blades located inside the drum. The rules for operation are actually the same as the rules for using a concrete mixer. Components are loaded in the same sequence while the device is running.
When implementing any construction project, equipment for preparing solutions is simply necessary. Its use will allow not only to obtain a high-quality solution, but also to significantly reduce the cost of physical strength, as well as the time of its preparation, in contrast to mixing with a shovel.
