How to choose the right tool?
First, we'll figure out the question: a building mixer, how to choose and what to look for? Buying a construction mixer, you need to realize for what purposes it is necessary. It is necessary to take into account the volumes of the mixed material and its consistency. For large volumes, powerful tools are required, for everyday purposes, simpler devices are suitable.
The same applies to the mass with a high viscosity, and various fillers( crushed stone, sand, gravel).For such materials you need a high torque, because you want to mix tight solutions. In this regard, if you intend to work with large volumes with a tight consistency, then units with a power of less than 1 kW should not be bought.
Smaller mixers are great for working with paints, varnishes, glues, where torque is not important, but speed. There are instruments with two speeds that can be used for both heavy and light materials. Mixer construction electric for concrete with built-in electronic control system, in many ways, will simplify the work.
For powerful tools you need a system to maintain the revolutions when working with the load. Alternatively, you can purchase a tool for working with all types of materials. However, it is not designed to work with a heavy load, use under such conditions will significantly shorten its service life.
Note! In the case of a drill mixer, under heavy loads, the spindle is often deformed, so it is worthwhile to carefully weigh the volumes of work to be done so that the purchase is not in vain.
All about the types and purposes of the nozzles
The nozzles for the tool deserve special attention. A construction drill-mixer, whose nozzle will not match the tasks that you need, will be ineffective. Heavy materials are always lowered to the bottom, so with stirring, they must be lifted, and the lungs, on the contrary, must be upset. Accordingly, these tasks are solved by nozzles, different in design. To lift the solution, attachments are used with a right-hand spiral, to lower to the bottom - with the left-hand spiral. The following types of baits are available:
- Screw - used for working with varnishes and paints. The blades of the screw squeeze the mixture down, and the top ones are pushed out, this does not allow the contents to splash;
- Agitators-crosses - are necessary for materials in which air should not enter;
- Combined - can be used with any materials.
Note! Simple nozzles have a ring, with its help the mixer can be resting on the bottom, the combined nozzles of such a ring do not, so they need to be kept on weight.
Mixer for building mixtures does not always come with a snap. The reason for this is that each consumer buys it for their own purposes, and nobody wants to overpay for unnecessary attachments, because they are purchased separately. But some companies, having carried out research and having learned average requests, produce tools with certain groups of baits.
What kind of electronics does an instrument need?
The hand-held construction mixer is equipped with an electronic adjustment system. So, the speed control allows you to select the best speed for a specific material. For viscous substances, the function of maintaining the speed of rotation is useful, which maintains the intensity of rotation. A smooth start does not allow splashing the composition at the beginning of the job. Unit Characteristics:
- Torque. One of the most important functions. The higher it is, the more suitable tool for working with viscous substances. So, the concrete tool needs for high-quality work in high torque.
- Number of speeds. For complex aggregates this is a very important factor, since it helps to dilute viscous materials.
Another important point is fixing the baits. To date, almost all manufacturers have moved to the standard M14.The nozzle is screwed onto the spindle and then unscrewed with a key. This allows even with a strong contamination to unscrew the nozzle without any problems. Also this standard allows the use of nozzles from different manufacturers.
Note! M14 is not the only standard, other fastening systems are also used.
