A high-quality mixer for mortar allows you to get a uniformly mixed construction composition. An analogue in the form of a concrete mixer is suitable only for rough configurations, and if the optimal consistency of a soft mixture is required, the tool in question will be the best solution. We study the features of this device, as well as its varieties.
What is a mortar mixer?
The unit under consideration is an electric device that has a similar design with a drill. Using a special nozzle, the workflow for thoroughly mixing the ingredients is carried out.
The specified equipment is divided into classes that differ in the volume of work performed. For domestic purposes, it is better to purchase an aggregate whose capacity is about one kilowatt. During industrial and complex operations, a device of greater power will become more relevant. The most powerful units are focused on long-term operation in industrial volumes.
Design features
In terms of ergonomics, experts recommend choosing a mixer for a solution with a convenient handle. Most often, it is a pair of staples (ring version). Powerful modifications are equipped with a T-shaped handle in the form of a wide bracket with a similar element perpendicularly mounted. The speed control button is located directly under the lowermost part of the handle.
This arrangement of the part makes it possible to reliably hold the tool at high speeds. Professional modifications include mortar mixers with a pair of spindle chucks. In them, two nozzles are installed simultaneously at once, rotating in different directions. This design feature ensures efficient mixing of the solution components. A pair of shafts provides maintenance of the device while increasing its efficiency.
Modifications
The manual mixer for solution is produced by various companies in most countries of the world. Models of Russian and Chinese companies are mainly exhibited on the domestic market. At the same time, the quality of the devices competes with European brands. The factories track the technology and the final production of modifications.
To understand the features of this tool, we will review some manufacturers. Let's start with Interskol, a subsidiary of the Spanish company Freud. Experts note that the device in question is very convenient in operation. Its characteristics:
- the number of spindle rotation modes - two;
- initial / final speed indicator - 130/850 rotations per minute;
- functional - mixer and drill;
- the mass of the device is 5 kg;
- simultaneous processing ability - from 120 liters.
User reviews indicate that the device is suitable not only for private use, but also as an industrial tool.
Other manufacturers
The SKIL 1613 model, which has a power of 1.4 kW, is presented in the model line. According to users, the device is quite ergonomic and has a convenient handle. It is worth noting that the system has a special controller that allows you to keep the rotation of the working shaft constant if necessary.
The REBIR EM mortar mixer is equipped with a drill function, differs from analogues in that it does not have an annular handle from the pipe, the modification refers to mini-models, the power of which reaches 1300 kilowatts. The device is used for mixing light mixtures and concrete solutions.
Leading brands
Among the world leaders, the following brands can be noted:
- Makita brand electric mixer for mortar. As you know, Japanese manufacturers are jealous of the quality of their products. Therefore, the Makita mixer is one of the most popular. There is also a fairly large selection of devices in terms of power and spindle rotation. For example, the 6013 is a small device weighing three kilograms. In this case, the speed of the unit is 550 rotations per minute. User reviews confirm the high quality indicators of the tool.
- Bosch mixer. No one doubts the German quality, therefore the price of the device is rather big. Costs are offset by the durability and reliability of the device. The rotation of the motor shafts is 450 rpm with a maximum rate of 1050. Judging by the reviews of the owners, this model is one of the highest quality, but its cost is much higher than its analogues.
- Skill Another popular European manufacturer. Units belong to the middle price category, proved to be excellent in household operation and small construction. According to users, this modification optimally combines quality and price parameters.
The principle of the mixer for mortar
Built-in electronic filling makes it possible to adjust the speed in automatic mode. This approach ensures the maintenance of a constant mode of operation, due to the uneven rate of mixing of the mixture. When filled with water, the components start a chemical reaction. As a result, a viscosity is created that exerts resistance when the particles move between them. In addition, the weight of the composition requires increasing power to move a certain amount of the mixture.
These and related factors through a special nozzle affect the motor, the number of revolutions at the same time begins to fall. Here the automatic controller is turned on, preventing braking from developing, supporting the workflow in optimal mode. All professional modifications of the tool in question are equipped with a similar device.
Attachment Method
On the mixers for the preparation of the solution, several methods of fastening the working mechanism are used:
- Thread. The nozzle is mounted on the spindle using a threaded lock. The system is reliable, but it creates some difficulties during operation.
- Cam type chuck. Fastening is carried out by means of a special key that regulates the position of the working element in its slot.
- SDS type connection. Practiced on rotary hammers, great for working with adhesives, plasters and putties.
- Connection Type Fast Fix. It is a quick-clamping chuck, used on screwdrivers. Among the minuses - mixing heavy mixtures leads to rapid wear of the corolla faces.
The most reliable methods of fixing the nozzle in the mixer include the Morse cone system. This design makes it possible to work with solutions of any density; it is used in most professional versions.
