How to choose a concrete mixer for a private house and cottages

Cottage and suburban area – this is not only kebabs and relaxation on fresh air, but also a large number of diverse construction work requiring the use of various equipment and equipment. Even the simplest concrete work will take place much more effective if you do not manually knead the solution, but resort to to the help of a concrete mixer. Modern devices of this class compact in size, excellent functionality and significantly increase labor productivity, allowing save a lot of time. All that is required of you is to choose suitable concrete mixer!

The best manufacturers of concrete mixers – which company to choose

Currently, a huge number of various types of concrete mixers with their own functional features that directly affect efficiency work. The price range also varies: you can buy as inexpensive Chinese model, and high-quality, but expensive equipment from famous American or European manufacturers. In general, experts recommend paying attention to the products of the following brands:

  1. Caterpillar;

  2. Denzel

  3. Inforce

  4. Zirtek;

Each of these manufacturers has in its own directory a large number of different concrete mixers, and in order to choose the best option, you should familiarize yourself with characteristics, as well as examine customer reviews to test this or that model in action.

The principle of operation and the construction of the concrete mixer

Concrete mixer designed for instant cooking high-quality cement-sand mixture for construction work. Such a device works automatically, but as a driving force almost always acts electric current. Main nodes Any concrete mixers are:

  1. Drum equipped with blades. Serves as a reservoir into which all components are loaded and mixed together cement-sand mixture;

  2. Frame – steel or aluminum frame on which all key elements of the device are fixed;

  3. An electric motor is an engine that drives a drum with blades;

  4. Control panel designed to control work devices

If the concrete mixer belongs to the household class and has acceptable dimensions and light weight, the scope of delivery may enter wheels designed for transportation and movement devices during operation.

Types of Concrete Mixers

All concrete mixers currently on sale are can be divided into two general categories.

Forced Concrete Mixers

Forced concrete mixers

They are a fixed tank, inside of which the shaft rotates with the blades fixed on it. It is with their help and is the preparation of high-quality cement-concrete mixture, uniform and well mixed. Concrete mixer enforcement actions are mostly professional devices held by construction trusts and organizations involved in monolithic work.

Advantages

  • High-quality mixing of concrete mixtures;

  • Long term of work;

  • High reliability;

  • Ability to work with a solution of various consistencies – from liquid to thick;

disadvantages

  • High price;

  • Demanding on the size of the fraction of the components used;

  • Significant power consumption;

Gravity type concrete mixers

Gravity type concrete mixers

The main unit of such a device is a drum, on the walls whose blades are fixed. It drives electric motor, and, being in rotation, the drum mixes components of the cement-sand mixture to a homogeneous state.

Advantages

  • Unpretentiousness to the used components;

  • Mobility;

  • Low cost;

  • Simple and reliable design;

  • Low power consumption;

  • It mixes even coarse concrete mix;

disadvantages

  • Low productivity;

  • To obtain a solution of uniform consistency, long work;

Gear type concrete mixers

Devices whose design is similar to the class described above, however, it differs from it in the type of drive used. In this models the traction force of the electric motor is transmitted to the drum through gearbox having a specific gear ratio. This allows adjust drum speed and reduce power consumption and engine load;

Advantages

  • High performance;

  • Simplicity of construction;

  • Maximum reliability

disadvantages

  • High price;

  • The need for careful operation;

Concrete Mixers

Gear type concrete mixers

The most common devices that are popular at home and when performing small monolithic works. Principle the action is similar to that of gravitational models, it differs only method of transmitting force from an electric motor. For this purpose a crown is used – a special toothed belt fixed by drum circumference. By interacting with the pinion gear, the crown drives the drum, and the solution is kneaded;

Advantages

  • Compact dimensions;

  • “Omnivore” – allow you to knead a solution containing a fraction various sizes;

  • Low cost;

  • Simple, unpretentious in operation design;

disadvantages

  • Low productivity due to the small tank volume;

    The need for careful monitoring of the state of the crown in avoidance of failure;

Concrete mixer selection options

Having decided on the type of concrete mixer, it is necessary to take into account its key features that directly affect functionality.

Total drum volume

drum volume

The higher the volume, the more concrete mixes at a time device. There is also the reverse side of the coin: for kneading a lot of mass will need a lot of electricity, and it is likely that some percentage of the finished mixture will be unused.

  1. For use in everyday life, models should be preferred, volume which will be up to 100-150 liters;

  2. Industrial production may require more spacious concrete mixers, from 150 to 300 liters;

  3. Professional monolithic work associated with large filling areas, require the use of powerful and roomy devices with a volume of more than 300 liters;

Engine power

A parameter that directly affects the performance of the device and the ability to work in particularly difficult conditions. For use in models with an electric motor are quite enough 500-800 watts. Industrial production may require much more powerful devices, up to 1-1.5 kW.

Voltage

A parameter that directly affects the applicability of a particular devices at home or at work.

  1. When used in a domestic environment should give preference for single-phase concrete mixer voltage 220V;

  2. Industrial models are almost always equipped with three-phase 380 volt motor;

The material of which the crown is made

Very relevant parameter for household concrete mixers, directly affecting the resource of the device.

  1. Polyamide is a strong, durable and reliable material. Is different high resource and unpretentious in operation. Crown of polyamide, usually has a four-part design, which simplifies it repair: if damaged, just replace the damaged one fragment;

  2. Cast iron. “Grandfather” material, widely used in budget devices. Sufficient durability subject to the rules operation;

  3. Steel. Used in the most expensive models of concrete mixers and provides excellent performance. The only negative is the price;

Which concrete mixer to choose?

Which concrete mixer to choose

  1. Buying a device for one-time construction work, preference is best given to the household model of the crown type, 220 V mains and equipped with an electric motor power 0.5-0.7 kW;

  2. In the case where the use of a concrete mixer will wear regular, gearing should be preferred type, operating from a network in 220V and having a tank volume of 150-200 liters;

  3. Professional execution of monolithic work requires use of appropriate equipment. Concrete mixer with a tank with a capacity of 250-300 liters, the electric motor of which It works from a network of 380 V. is the best choice.

How much does a concrete mixer cost?

  1. Compact gravity concrete mixers with up to a tank 100 liters is quite budget: their cost rarely exceeds 10 thousand rubles;

  2. Coronal devices for domestic use have a similar order. numbers on the price tag – from 8 to 15 thousand rubles;

  3. Professional forced equipment is the most expensive. Prices for models from well-known manufacturers almost always start with a mark of 50 -55 thousand rubles and can reach up to 200-250 thousand.
