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.
Reduction drive
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").
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.
