The manual mixer for concrete, which is a special nozzle-mixer for a drill, has a very wide application for the preparation of a variety of building mixtures, and is also used as a tool for working with glues and varnishes of various kinds. All this is possible due to the high quality of mixing and ease of operation. However, when choosing such a device, all factors that can affect its operation should be analyzed.
Before you buy a mixer for concrete, you need to decide on the amount of work that you will perform with it, and only then choose a power tool in accordance with this. If you are interested in conducting an independent home repair, then you may well be satisfied with the household option, while saving up to 30% of the cost. If your profession is construction, then you should purchase a more professional device.
When choosing a mixer for concrete, it is necessary to take into account its power, for which you need to determine in advance the type of
construction mixes with which you will work. For example, for the preparation of building mixtures based on
concrete, which contains various fillers in the form of gravel, expanded clay or crushed stone, high torque is very important. In such cases, the best option would be a power tool whose power is kilowatts or more. If you are interested in a manual concrete mixer, the price of which is from 2000 rubles, for preparing light mixtures, for example,
parquet varnish or tile glue, then a tool with less power will help you, because in this case the speed is important, not the torque. A professional tool, and sometimes a household one, has the ability to control the speed, that is, you can choose a specific speed, which allows you to use the device for preparing different types of mixtures.
If you have already bought a concrete mixer, you should also carefully approach the issue of nozzle selection. To make the right decision, you need to determine what type of mixture the work will be carried out. We can say that in general there are three types of nozzles for the mixer: screw, cruciform, combined. The former are used for mixing paints and varnishes, the latter should be used in situations where air entering the mixture is undesirable, and the others are useful for any materials.
Fixing nozzles in any mixer is not particularly difficult, since everything is unified here. Manufacturers use the standard M14. He assumes that the nozzle will be clamped into the cartridge, and if it needs to be replaced, then you can unscrew the cartridge using a special gear wrench. The same standard applies to adapter chucks for rotary hammers, allowing them to be used as a mixer for concrete. For some cases, this option becomes a real salvation.
In conclusion, we can say that, when purchasing a construction mixer for concrete, it is necessary to pay attention to the presence of high torque, sufficient power, as well as the possibility of changing the speed of work.
