Electric concrete mixers facilitate professional construction work. The selection criteria are clearly influenced by the ability to conduct specific volumes and final results.
Features
When choosing an electric concrete mixer in Moscow or another city, pay attention to the design of the unit. It can consist of a screw device or have a drum mechanism. Units of the first modification have a rotating core, which mixes the components due to internal rotation, combining liquid and viscous solutions. The result is a homogeneous plastic mixture.
Such equipment is used for a significant amount of construction work. Such a system requires significant costs, including a certain design configuration.
Short description
An electric concrete mixer for the home is not just a mechanism, but a device that requires evaluation in comparing the criteria of quality, price and additional costs. The mechanism is based on the rotation of the drum with the remaining internal blades remaining in a static position.
For example, a gravity electric concrete mixer makes it possible to carry out construction work on a private courtyard or small site without the involvement of professional crews. In this case, it is possible to produce independently concrete mixtures of various categories in a small volume.
Varieties
Before purchasing an electric concrete mixer, you should pay attention to the following points:
- Type of torque transmission (sometimes gravitational or gear type).
- Cost.
- Power indicators.
- Reliability and uninterrupted operation.
- Maintainability.
Gearboxes
Gear-type electric concrete mixers are equipped with a separate enclosed unit, which prevents sand, gravel or cement from entering the structure. Such units have a reliable assembly and low noise level. All operational characteristics are manifested in view of the proper maintenance and use of equipment.
When the device fails, it will be necessary to organize a laborious repair process. It is quite problematic to do it yourself, because it requires the participation of specialists, which is expensive.
Aggregates with crown type of work
Electric coronal type concrete mixers are equipped with an open mechanism, which is fixed on the body of the circumference of the unit drums. The fixture is exposed to building compounds, which increases the percentage of deterioration of parts. The advantages include unpretentiousness in maintenance and ease of operation.
The popularity of coronal units is due to the optimal and understandable design, as well as maintainability. In turn, gear analogs are more productive and reliable, however, they are difficult to use and require the participation of a professional to repair.
Design
How to choose an electric concrete mixer? Inexpensive it is best to purchase domestic equipment in specialized stores or via the Internet. To do this, you need to determine the operating mode of the equipment. In this regard, there are devices of continuous and periodic action. The second option overheats faster and is not suitable for intensive and frequent use.
The electric concrete mixer is more durable and is often used for production purposes. Continuous cycle machines will cost from 80 thousand rubles. Units are serviced, as a rule, by a shift of two operators.
Manufacturers
The following is an overview of concrete mixers from the best manufacturers. Let's start with the Lebedyan brand. Specifications:

Profmash B130
A high-performance manual electric concrete mixer is presented in the review by a model from a domestic manufacturer. The package includes a mixer, a polyamide element with four crowns, the ability to remake the working part from metal to a plastic analog.
Steel is a reliable and durable material compared to cast iron. It does not crack when dropped. At the same time, the cost of such a mixer will be higher. In the manufacturing process of the part, it is first poured into a mold and then cooled. Then the resulting workpiece is ground on a machine and adjusted to hardening.
"Bison ZBSE-120"
A standard gravity concrete mixer with a dosed feed of the finished solution has the following characteristics:
- Power - 400 watts.
- The volume of the kneaded and obtained mixture in liters is 120/60.
- Dimensions - 360/720/810 mm.
- Weight - 60 kg.
- Estimated cost - from 10.5 thousand rubles.
Inforce BS 140/600
The compact and stable modification is equipped with a corrosion-resistant coating, has a long working life and the possibility of many hours of continuous operation. Bearing elements are located inside the drum mechanism.
Parameters:
- Power indicator - 600 watts.
- Loading / delivery of the solution - 140/75 l.
- Dimensions - 1290/1055/690 mm.
- Weight - 57 kg.
"Foreman ECM 140"
The manual electric concrete mixer of this brand is distinguished by a high protection class IP45D and a reinforced frame with metal slopes.
Main characteristics:
- Cost - from 18 thousand rubles.
- Dimensions - 820/720/440 mm.
- The working functional of loading / output is 140/10 liters.
- Weight - 6 kg.
- Power - 650 watts.
"Whirlwind BM-120"
Below are the technical specifications of the electric mini concrete mixer from this manufacturer:
- Dimensions - 610/400/580 mm.
- Weight - 28 kg.
- Performance indicators - 120/85 l.
- Power - 450 watts.
- Price - from 9.5 thousand rubles.
Simple and compact modification is equipped with additional stiffeners on the drum mechanism, fixing is carried out using a foot drive.
How to choose an electric concrete mixer?
When choosing the technique in question, you should pay attention to such important points:
- Accounting for the working volume of the drum and its delivery of the finished mixture. For example, when performing one-time work up to 100-120 liters of concrete output, a mini-version with a mechanical drive is quite suitable. For larger-scale construction, vehicles with a capacity of 150 liters and above are required. Models with a volume of more than 300 liters are used for the construction of multi-storey buildings.
- Power parameter. The higher this indicator, the longer the equipment will be able to function continuously at the maximum load of the drum. Depending on the required capabilities, choose machines with power from 0.7 to 1.5 kW, taking into account the volume of work and comparing them with the characteristics of the equipment.
- The material of manufacture. The version with a cast iron knob works more actively, includes polyamide gears and a gear transmission. The node has a long service life, while users note good quality in terms of continuous operation.
- Forte with a 150 liter activator will cost at least 15,000 rubles, in contrast to the analogue, which is known for its anti-corrosion coating. Such nodes are easier to buy and use in the process of large-scale construction.
Recommendations
According to reviews, electric concrete mixers with a volume of more than 180 liters in household use are not functional. When choosing equipment, you should pay attention to such an indicator as the yield of the finished solution. Many manufacturers overstate or hold back this figure. Despite sellers' assurances that the drum can be loaded to the maximum, the actual filling of the tank is no more than 2/3.
Among other things to pay attention to:
- Type of motor protection. There should be a special casing and proper placement of the ventilation grille with protection from sand and cement.
- The possibility of unloading the mixture in metered portions with the rotation of the mechanism in different directions. Modifications with an adjustable wheel allow you to fix the drum at the right angle, which greatly simplifies and speeds up the work process.
- Strength and shape of the blades. Customer feedback indicates that elongated elements with slots in the middle are the best option.
Total
An electric concrete mixer makes it possible to facilitate the construction of various facilities. When choosing a modification, you should take into account the reviews of the owners and the characteristics of the device. If the machine is required for one-time use, it is more reasonable to rent it. In other cases, it is necessary to take into account the capabilities of the equipment and the estimated scope of work.
