Real power

The useful power of the tool is the maximum power that it can deliver to the working nozzle. This power is always less than the power consumed (see below), since part of the electricity inevitably goes to heat and friction in the tool mechanisms. In addition, this parameter is not given for every model, often information in the characteristics is limited to power consumption. Nevertheless, the actual capabilities of the tool directly depend on the net power: the higher it is, the greater the speed and/or torque this model is able to develop, the easier it is for it to cope with tasks that require high efforts. So, to compare different devices with each other, it is best to use this parameter (of course, you can only compare models of the same type or similar in type).

Also note that high working power is not always an advantage: it accordingly affects the dimensions, weight and price of the tool, while in fact high speeds and efforts are not always necessary. Detailed recommendations on the optimal values for different tools and different types of work can be found in special sources.

Power consumption

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.

Rotation speed

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.

Max. torque

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.

Max. mixing paddle diameter

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.

Max. stirred weight

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

Functions

Soft start. This function allows you to avoid a sharp start of the engine at the beginning of work, which, on the one hand, allows you to avoid overloads on the power supply network, and on the other hand, splashing of building mixtures.

Speed controller. The ability to adjust the speed of rotation of the nozzle of the working tool will be very useful for working with mixtures of different consistency. As you know, for effective mixing of liquid materials, a high speed is required, and for viscous materials, a lower speed, but a higher torque.

Maintain momentum. With the help of special sensors, the speed control system monitors changes in load and, depending on this, increases or decreases the speed of the nozzle, thus maintaining the speed set by the user, regardless of the load. This ensures more efficient and better mixing and extends the life of the device.

Power button lock. Locking the power button when the tool is off allows you to avoid accidental start in abnormal mode, which increases the safety of the device. And vice versa: locking when the tool is on eliminates the need to constantly keep your finger on the power button, which is very convenient, especially during long work.

Electronic engine protection. The system provides automatic shut...down of the engine in case of overheating, jamming of the nozzle, or simply in case of a critical increase in load, which helps to avoid tool failure and extend its service life.

Brushless motor. The presence of a brushless (brushless) motor in an electric tool. Such motors are noticeably superior to traditional collector motors in terms of efficiency, which can significantly reduce energy consumption without sacrificing power; this is especially important for cordless tools (see "Power Source"), where this feature is predominantly found. In addition, brushless motors are quieter and produce virtually no sparks during operation, making them perfect for working in high fire hazard environments. Their main disadvantages are traditional — the complexity of the design and high price.

Weight

This refers to the weight of a fully assembled and ready-to-use construction mixer or drill mixer. What you need to pay attention to here is that the small weight of the device is not always its advantage. On the one hand, during operation, the tool has to be kept on weight, most often in a vertical position, which is very tiring. But on the other hand, heavy models are less susceptible to vibration, it is easier to fix them in one position.
