How to choose a concrete mixer for the house? Main criteria for the selection of concrete mixer

Construction & ndash; is a complex process, sometimes long and very difficult, especially physically. And, of course, different construction tools and equipment have already come up with many different useful things, which greatly simplify the work. And mixer – not the exception. By the way, the claim that for the private use of the equipment – an unnecessary luxury, just a myth (if you know how to choose a mixer for your home or small working teams).

General classification

The Building is of different scales. And depending on this, there are several basic types of equipment. First of all, this large-sized concrete mixer. They are indispensable in large-scale construction, for example, high-rise and multi-family homes, and utterly useless in private construction. For this there are compact models. They are designed specifically for private teams and home use where a large volume of solution is required. And to work with them, of course, several times lighter. How to choose a concrete mixer for private masters? It is necessary to rely on multiple criteria.

Movement

Still thinking about how to choose a concrete mixer for construction work, just decide for yourself what type of management needed. For example, in the construction of small scale (private) would be enough and manual equipment. It is cheaper than the automated counterparts, but requires physical effort in the work. On the other hand, automatic cement mixers small in size for a reasonable amount – it is an undeniable assistant for private construction. Here, everyone decides for himself what he needs to. Mixer manual – it's not just the consumption of physical strength, but also significant costs in time, that not every Builder can afford.

Bowl Volume

Drum concrete mixer is one of the key elements that you need to pay attention to. Bowl volume to one hundred fifty liters suitable for private construction. While those who are just still thinking how to choose a mixer, you should remember that the solution volume will be 2/3 of the volume of the drum. This is due to the process of mixing building mass and release it from the equipment. Can't believe sweet speeches and promises sellers that 130-liter mixers, it is possible to obtain 100 liters of solution.

The Engine and its power

It is widely believed that the more powerful the device the better it works. Regarding mixers is a myth, nothing more. The more literate you are using the equipment, the better and better it works – that is a fact. And the performance is not so strongly influenced by the power of the engine. Although this criterion can not be discounted. How to choose concrete mixer, focusing on the power? For private construction usually offer equipment up to 1 kilowatt. It is considered unprofessional, lightweight. When buying, always pay attention to the required voltage. For example, there are models of concrete mixers, which operate from the mains at 220V, and there are those that require more – 380 V and above. In this case, may additionally require a stabilizer or a generator. And, of course, wondering about how to choose the right mixer for your home, remember that for a long time requires a lot of power. If the period of use of the equipment does not exceed 12 hours, that is fine and 700 watts.

Upload solution

Also Important is how does the retrieval of the prepared solution from the drum. Of course, a powerful and large construction concrete mixer equipped with automatic feeding the finished mixes. Are there any for a private operation? Typically, the loading and unloading occurs in manual mode, if the volume of the drum less than 300 liters. But some manufacturers go to meet their customers and made a small cement mixer with semi-automatic feed system ready solution - for example, through the pedals. That is, to exert physical force still have. If you want to choose a concrete mixer for the house, pay attention to such models. This saves power when building.

Mixing

It would Seem that is easier: loaded cement, sand, poured water, turned it on and let equipment interfere with the solution. But all is not as it seems at first glance. There are two types of work of concrete mixers, regardless of their size and power. Each of them has its own advantages, disadvantages and purpose.

Gravitational effect

This type is considered universal and suitable for construction of any scale. A key feature is that the mixing and preparation of the solution is due to the blades located inside the drum. They thoroughly mix cement, sand and water to make a homogeneous mixture. Thinking about how to choose the right concrete mixer? Consider, on what principle it works.

Force action

This type of mixing is more suited to equipment designed for large-scale construction projects. Serious drum volume, impressive power – all this requires the most careful way of blending solution. Think how to choose a concrete mixer according to the principle of its action? Remember that equipment with forced mixing mode – this is an option for liquid concrete. That is, knead it cool the solution (e.g. for masonry or basement walls) are unlikely to succeed. In addition, on the market are not so many models of small volume with the specified type of mixing.

Gear

The gravitational kneading Mixers are divided into two types – and the crown gear. The first has earned a good reputation as reliable and durable. But wide distribution has not received. The fly in the ointment – complex repair. If the concrete mixer of this type breaks down, to replace the gearbox will be problematic, and in some cases even impossible.

Think about how to choose the concrete mixer with gravitational method of kneading? Note the coronal stirrer. They have a lot of advantages.

Coronary agitator

In another way, they are also called girth. Their lifetime is somewhat less than the gear. But when repairing this type of equipment is less whimsical, all items are easily replaced. What exactly is not you need to do is lubricate the mechanism inside, which may affect the work, slow it or even stop it.

It is Important to do when choosing – is the material from which the body of the mixer. For example, the drum itself can be made of metal, but the mechanism is covered with plastic. What is bad? Plastic tends to quickly come into disrepair. Good equipment – metal. This greatly adds his weight, but of reliability and validity do not have to borrow. Pay attention to how well hidden the control device, if electric mixer. And manual should keep from rain, snow and ice.

Practical advice

However, the manufacturer and the country in which the equipment do not always guarantee quality. Before buying will not be superfluous to ask the owners of similar models on the quality of the work of the mixer. Even with the pipelines of some of the eminent manufacturers go to such models which are not adapted to work with the solution. And, of course, you can always make yourself a cement mixer, if you have time and a little ingenuity. Suitable materials can look in their own bins or in specialized stores. Cost will turn out cheaper than to buy ready-made equipment.

How to make a concrete mixer?

To assemble the agitator, which will operate in manual mode, you will need not so much:

• Drum (you can buy a small volume specialty store or accommodate a tank of suitable shape);
• Relay (knob, which will scroll the reel);
• Stand (spinning tank).

In addition, you can take the blades that you want to weld to the tank, unless you have purchased a special drum, of course. Install the design on the front, insert the relay so that it is easily scrolled by moving the tank. Of course, such an improvised mixer will not differ a special quality of the solution, but for home use is quite suitable.
