How to choose a solution mixer

No construction event associated with the pouring of concrete cannot do without a solution mixer. This technique allows for counting minutes to prepare a high-quality solution, saving time and strength of the working brigade. In order to correctly choose a concrete mixer, you need to familiarize yourself with the technical characteristics, take into account operating conditions and purpose. In this article, we will consider in detail the popular models of mortarmers.

Species of mortarmes

Mixer mixers There are a lot, but the principle of operation of all models is reduced to one: the components of the solution are connected in one container and stirred by mechanically to obtain a uniform mass of the required consistency. A more common name of the solution mixers - concrete mixers. However, this does not mean that they can only work with concrete - equipment, if necessary, is used to knead other solutions from bulk ingredients, for example, for finishing works.

It is useful to know: concrete mixers professional builders call the simplified design of the gravitational principle of operation. According to the rules, if the mixed solution consists of a filler with a size of 1 to 7 cm, the machine is called a concrete mixer. If the diameter of the filler fractions does not exceed 1 cm, such a technique should be called a solution mixer.

To know how to choose a solution mixer, you need to understand what the differences between the models are. Each of them has a different capacity of the drum, power consumed, constructive execution, etc. There are differences in the characteristics of the resulting solution after stirring - it may be cement concrete, a pennation, a slag concrete, gypsum concrete, ceramic concrete or other non-clear types of mixtures. The basis of any solution is a mechanism with blades, located inside the drum and driven by an electric motor. The presence of other nodes depends on the configuration and purpose of the machine (support elements, traverse, tipping mechanism, electrical equipment, etc.).

Mixer mothers on the principle of work

All models of mortar mixers can be conventionally classified by two main categories that differ in principle: periodic and continuous. In the first case, the machine works cyclically and with certain interruptions. Such models are mainly acquired for domestic use, since in this case the scale of work is not so large, as in industrial construction, and work can be stopped at any time.

Concrete mixers of continuous action are characterized by a greater power compared to periodic. They are also more difficult from a constructive point of view, since all components are designed for long-term and non-stop operation, which means that they have increased wear resistance. In the amount, all these factors are reflected at a fairly high price. Continuous mortarmers are rarely used in private construction, since all its technical potential they can disclose only in conditions of a large-scale construction site, where the brigades workers work in a few shifts and we are talking about large volumes of the solution.

Mixed Mixed Mixing Method

Despite the fact that in all concrete mixers, the solution is mixed with special blades, the mixing method may differ. There are compulsory and gravitational principles of impact on the solution.

In machines with forced mixing, the drum is fixed, and only the blades are working inside it. And the gravitational concrete mixer can be distinguished by the rotating drum. The principle of operation is hidden in the title - mixing of the solution is carried out by influencing the gravity force. On the inner walls of such a drum attached blades, and when the drum begins to spin, the solution flows from one blade to another, evenly mixing.

Mixed mixers with a compulsory mixing method are considered to be more productive than cars with gravitational drums. Basically, they are used in plants for the production of concrete. They are ideal for working with liquid solutions from small-flow fillers. Below on video shows the principle of operation of forced concrete mixer:

Gravitational models are good for home use or small private construction. They differ in greater compactness compared with forced, and also do not require such operating costs (less power). Simple design breaks extremely rarely, and wear-resistant components serve for many years.

Silence mixers by type of device

And the last thing you need to know for an adequate selection of the solution mixer is the type of device. This means that the machines have a specific technical package that characterizes its operational characteristics, quality and durability.

By type of device, mortarmers are:

1. Wenty - can also be called belt or corona. This type of machine has a drum with a gear wheel around it (crown). The highest quality is the steel crowns, but they are quite difficult to produce, so in most models there are cast iron or generally plastic components. Both cast iron, and plastic are short-lived, and it is possible to understand that the crown of the mortar mixer is not made of steel, in the cost of the model. In addition, the car with a cast-iron crown is very noise.
2. Reducer - There is no price in such cars and the belt at all, and the pear is attached directly to the gear shaft. Such mortar mixers are durable and more productive, but their main disadvantage is that if such a car breaks, the repair will be very expensive, since the gearbox will need to be fully changed.

Venetic concrete mixers are best suited for private construction. Though they are not so durable as gear, but repair them is much cheaper and easier.

How to choose a concrete mixer

When choosing any construction equipment, it is necessary to repel from the alleged amount of work. If you are planning to pour a concrete foundation once, and then use a solution of the mixer once a year, it makes no sense to buy an expensive professional model. However, if you are going to pour the same concrete foundation, and then take a solution to a solution for rent, you can purchase semi-professional products of the average price category.

Not only the frequency of use, but also the required volumes of the solution affects the choice - the capacity of the drum depends on this. For private construction, machines with a drum up to 100 liters are mainly used. Another important criterion is how much the technique is protected from external influences. Protection is represented by insulating coatings and covers. The inner walls of the drum should be treated with anti-corrosion and wear-resistant compositions, the engine should also be protected from premature abrasive wear. Ideally, the concrete mixer should easily understand that after completing construction work it could be cleaned. The cost of the solution mixer depends on its functionality. Before you acquire any model, you will certainly read its technical characteristics.

What should be paid attention to:

1. Tank capacity - focus on the upcoming volumes of work. For the construction of a single-storey building, a garage, a toilet or a barn, a tank is suitable for 90-100 liters. If you want to simply lay a tile or make garden tracks, you can purchase a completely compact model by 50 liters. For the construction of a building in 2-3 floors, the volume should be slightly larger - by 100-130 liters. It should be taken into account that the amount of solution obtained after stirring is always obtained by 30-40% less than the claimed volume of the tank. For example, in a gravitational machine by 65 liters, it is not more than 45 liters of the solution at a more time, and in a more productive model by 180 l - no more than 120 l of the ready mixture.
2. Power consumption - the ability of equipment depends on the engine power to qualitatively mix large or small ingredients. It is worth notify that there is no productivity here here, that is, this does not mean that the engine is more powerful, the more a concrete mixer can do. As a rule, this connection is observed between the increase in power and the volume of the tank, because the greater the tank, the greater the solution it is necessary to mix and the stronger the engine should be. However, there are no restrictions here - engines in household models operating from 220V, have a maximum power of 1 kW. If you need a more powerful mixer, you will have to select a model that can work from 380 V, although, as practice shows, a capacity of 700 watts is enough for home use.
3. Case thickness - the thickness of the drum, the longer the concrete mixer will last. The components of the solutions are slow, but even the most durable steel is correct, therefore the body thickness should be at least 2 mm.
4. And the last thing to pay attention to when choosing a model is its color. Here we are not talking about whether you like yellow or green concrete mixers, but about the question of security. It is better to give preference to the brightest colors so that the concrete mixer was noticeably from afar during any weather. Therefore, green, gray and brown is better to avoid, and yellow or orange will well stand out against the background of any landscape.
   

Useful advice: If the concrete mixer has a wheeled frame, it will be easily transported by the construction site, thereby reducing the cost of operation and using the use of the technique more comfortable.
