Comparison Dnipro-M BM-160S vs Compass HM-130E-2

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 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").

— 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.

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.
