Construction mixer: photo, characteristics and rating of fixtures - Setafi

The construction mixer, the photo of which is presented in the article, is mainly used for preparing mixtures of different densities. Some models can also be used as a drill for wood and metal. When choosing, first of all, pay attention to the power and speed of rotation. No less important parameters are the convenient location of the handles and the weight of the tool. The basic selection rules are described in this material.

Main technical characteristics

To figure out how to choose a construction mixer, you need to study several technical characteristics. Among them, the mixing speed of the solution, as well as power, feeding method and other parameters are of great importance.

Speed

The devices operate at 2 speeds, which are measured by the number of revolutions made in one minute:

1. The first lies in the range from 500 to 650 full rotations in 1 minute. Suitable for mixing with a solution with a very dense consistency. They can be well processed, for example, putty.

2. The second one is from 700 to 900 spins. Suitable for lighter mixtures. It can be varnish or paint.

Some devices are equipped with only one speed, others have two at once. Moreover, if we say which is better - a concrete mixer or a mixer, it is not necessary to focus on speed. In this sense, the volume of the mixture is more important. If you need to prepare a small amount of concrete up to 1.5 m3, a mixer is also quite suitable. When mixing larger batches, a stirrer is indispensable.

Power

To make a bargain, take into account the rating of construction mixers. Moreover, it is easy to see that different models differ in their power. For mixing a liquid mixture, a unit with an indicator in the range from 600 to 1000 watts is quite enough. If the mixture is viscous like a primer, a more powerful model from 1000 watts is required. If you mix dense solutions using cement, the indicator should be at least 1500 watts.

Feeding method

The choice of a construction mixer is also related to the type of food. According to this indicator, devices are divided into 2 classes:

1. Network (220 V).
2. Rechargeable.

On the one hand, battery-powered models are more convenient. They are mobile, portable and can be used almost anywhere. But on the other hand, the battery needs to be constantly charged, besides, after 2-3 years of active use, a replacement may be required.

If you use a network tool, these problems are not present, but it is limited by the length of the cable. If there is no outlet, it will not work. Therefore, the question arises as to whether it is possible to use a perforator as a mixer. This is a perfectly acceptable replacement, because both units are equipped with approximately the same electric motor. In addition, a hammer drill is a fairly common tool that is likely to be found on a construction site or in the household.

nozzle type

This indicator largely determines the type of construction mixers:

• framed;
• screw;
• screw.

Framed are used to prepare those solutions in which you need to get rid of air bubbles. They are used, for example, to prepare a composition with an adhesive base.

The screw nozzle is used to work with liquid solutions of low density. It can be a composition with paint or varnish. The screws are equipped with 2 spirals that work in different directions. One spiral pushes the mixture up, the other down.

If you figure out which construction mixer is better to buy, you can pay attention to the screw mechanism. It also consists of 2 spirals - right- and left-handed. This is the best option for different mixtures, and cooking is gentle, as the liquid splashes on the sides.

Handle type

This is no longer a technical, but a consumer characteristic, which also matters. Handles can be in the form of a ring or the letter "T". The ring option is not suitable for everyone, because hands can be very tense during operation. Therefore, it is better to choose the second option.

It is worth considering that the greater the power, the greater the width of the handle should be. In this sense, it does not matter which is better - a concrete mixer or a construction mixer. Both devices work with viscous mixtures, so you need to hold the unit in your hands and make sure that the handle is comfortable enough.

Model Rating

After studying the technical characteristics, it becomes more clear which construction mixer is better. To specifically answer this question, it is also worth studying the rating of different models. If you choose the best options in terms of price-quality ratio, you can pay attention to the following options:

1. 1. BOSCH GRW 18-2 E - a device of a well-known German brand. It features a high power of 1800 W, high-quality assembly and the ability to adjust the speed through an electronic system. But at the same time, the price is higher than that of a number of other instruments.
   2. Metabo RWEV 1200-2 - Another German instrument that develops a power of 1200 watts. Equipped with 2 rubberized handles, making it comfortable to hold during operation. If we consider which construction mixer to choose for different jobs, we can focus on this particular model. Along with kneading, it is used for drilling in wood and even metal.
   3. DeWALT D21510 - a light and compact device (weight exactly 3 kg) with an average power of 710 watts. At the same time, it has a high torque of 50 N * m. Allows you to fit different whisks with a maximum diameter of 160 mm. Considering which drill mixer is better to choose, you can stop at this option.
   4. Makita UT1401 – a powerful device of 1400 W with a maximum speed of 730 rpm. Equipped with a 3 m cable, while the weight is not too big - 5.5 kg. It has 2 rotation speeds, equipped with a soft start mechanism. But in some reviews, an uncomfortable handle is noted.
   5. RedVerg RD Mix develops power of 1500 W, operates in 2 speed mode, can gain 800 rpm. Equipped with 2 handles with anti-slip insert, convenient to operate. Another plus is that heat is quickly removed when the gearbox is heated. Therefore, the device can be used continuously for a long time. At the same time, the weight is 8 kg, so it is better to work in one place.

Thus, there are several criteria by which you can understand how to choose a manual model concrete mixer. Each model has its own characteristics, pros and cons. Therefore, before buying, you need to analyze not only technical, but also consumer characteristics.
