Comparison Vitals Professional Em 1612-2BR Twin Mixer Plus vs Eibenstock EZR 23 R R/L Set

The power consumed by the construction mixer (see "Device") during operation. High power provides the device with high performance — such a model can easily cope with complex tasks, such as mixing a large volume of mixture at a time or while working with heavy fillers, such as crushed stone. On the other hand, high power affects the power consumption of the device, its weight, dimensions and cost. It makes little sense to purchase a powerful model if you select a tool for domestic use from time to time.

The rotation speed of the nozzle or mixing container provided by a plaster mixers. High rotation speed devices work best with paints, varnishes and glues. Low rotation speed models do a good job of preparing thick mixtures. Many modern plaster mixers and mixer-drills support the ability to adjust the speed (see "Features"), which allows user to choose the most optimal mode for a particular mixture. Powerful tools especially need a rotation under heavy load support system.

The higher the torque, the better the tool handles viscous masses, where special force is required to turn the mixing nozzle. It is measured in Newtons per metre (N/m). Note that with an increase in the speed of rotation (see "Number of revolutions"), the torque decreases, and vice versa.

The vast majority of attachments for construction mixers have a standard size in length, usually 600 mm. But their diameter may differ, its maximum size is limited by the manufacturer, which must be considered when choosing. The indicator depends on the technical characteristics of the tool. The most popular sizes are 120mm, 140mm and 160mm nozzles. The larger the diameter of the auger, the easier it can cope with a large volume of mixed mixture.

The ability to switch speeds allows you to cope with various types of tasks: low speed and high torque are perfect for mixing viscous or heavy mixtures, and vice versa — high speed and low torque are better to cope with liquid materials such as paint, glue, etc.

Note that the support for two speeds provides the presence of a two-speed gearbox. At the same time, many modern construction mixers with a single-speed gearbox support the ability to smoothly adjust the speed of rotation of the nozzle (see "Functions / Capabilities").

Type of reverse provided in the design of the tool.

Reverse allows you to switch the direction of rotation of the nozzle. The type of switch responsible for this function is also indicated here. There are sliders, flags, and on the start button. Here is a detailed description of each of these varieties:

- Slider. The switch is in the form of a slider with two opposite positions. As a rule, it moves in the “back and forth” direction relative to the tool chuck - this format is considered the most practical. The sliders are quite simple and at the same time convenient and visual. That is why they are the most popular option nowadays.

— Flag. A switch in the form of a flag, usually installed above the start button and flipped left and right. One of the advantages of a checkbox is that it is right at hand and can be switched with virtually no unnecessary movements (which is not always possible with a slider).

- On the start button. Reverse switch combined with the start button. Such a combination button is usually made in the form of a “rocker”, and the direction of rotation depends on which side of the rocker the customer pressed; The same press immediately starts the engine. This design allows you to easily and quickly change the direction of rotation - for this you do not need to be distracted by individual switches, just move your finger slightly and press the other half of the start button.
...
— There is no reverse. In models without a reverse function, you will have to use special right- and left-handed whisks to mix solutions. Nozzles of the first type are intended for the preparation of thick cement and plaster mixtures, of the second order - for mixing substances with a low degree of viscosity. Mixers with reverse do not have such strict requirements for twisting the spiral in the working nozzle, since the direction of rotation of their shaft can be easily changed.

Numerical value, expressed in liters, indicating the maximum volume of solution that the mixer can mix in one step.

The type of internal thread of the spindle determines the possibility of using one or another nozzle with the tool. Also pay attention to the "Type of cartridge" (see below). Most construction mixers today have a metric thread on the spindle for attaching nozzles: M12, M14, M18, M20, M24, but there are also spindles with ⅝” inch internal threads.

The chuck type determines the mechanism by which the attachment is attached to the construction mixer and by which the energy of the tool is transferred to the work area. Nozzles with different types of fastening are not interchangeable.

— Key. One of the simplest and most reliable solutions, well suited for tough jobs. The nozzle is fixed in the cartridge using a special key, and after work it is removed with the same key that is included in the package. Even if you fill the junction with glue, the nozzle is still easy to remove with a wrench and improvised tools. But this process can become problematic if you lose the key. Due to the great popularity of this mechanism, the user can use nozzles from different manufacturers.

— Quick release. Models of this type use the FastFix (QuickFix) quick-clamping clamp, due to which the drill is fastened without the use of additional tools. This allows you to quickly change the tooling without much effort, the user does not need to resort to the help of any improvised tools, hand effort is enough. A simple and convenient solution, but some experts consider it not the best option for heavy work.

— Morse taper and key. The attachment of the nozzle of these tools has a special tapered shank that is inserted into the tapered hole of the spindle. The main advantage is high centering accuracy. Most often used in...mixer drills, but not very popular.
