Gravity and forced action concrete mixers are in high demand on construction sites. The parameters of the models are quite different. If we consider forced-type devices, we can notice the following: they can all work with concrete of different grades. They are often used for mixing refractory mortars.

Also, these devices are suitable for the preparation of finishing mixtures. However, their benefits do not end there. With adhesive mixtures of increased viscosity, they do an excellent job. For example, you can knead the plaster. The average cost of a new forced-action concrete mixer (market price) is about 60 thousand rubles.

Modifications with a horizontal camera arrangement

Horizontal chamber device (forced planetary concrete mixer) is usually produced with electric motors. Directly starters are available manual type. Plates for kneading are used quite wide. Thus, the performance of such devices is high. Also, a distinctive feature of the model can be safely called the presence of a crankshaft drive. In order to assemble the device yourself, you need a regular barrel. In this case, the gearbox is used manual type. The suspension is directly installed at the bottom of the frame. If we consider modifications with a tank of 500 liters, then the electric motor should be selected for 12 kW.

Vertical Camera Models

Device with vertical chambers (drawings of forced action concrete mixer are shown below) are in great demand nowadays. In this case, an electric motor is not required to assemble the model. The tank for these purposes can be used for 400 liters. It is more expedient to select a steel frame. A long stand is used to mount the tank.

In order to rotate the shaft, a special handle is attached. In order to be able to load the mixture into the barrel, a hatch is cut out. Depending on the comb, the quality of the mixture may vary. It should also be noted that mixers with a vertical arrangement of the chamber can be manufactured with electric motors of various capacities.

Belt driven devices

It is quite simple to make a forced-action concrete mixer with your own hands with a belt drive. First of all for the modelthe reservoir is taken. In some cases, a regular barrel is used. In order to install racks for it, you will need to use a welding inverter. Quite often, partitions are welded on the sides in order to increase the stability of the structure.

After fixing the tank, you can proceed to install the central shaft. In this case, the drive will require a crank type. You can use it from a broken concrete mixer. A belt type gearbox is installed next to the motor. In order to secure it, a small metal platform is made.

The motor should ultimately not come into contact with the frame. In order to install the gearbox, the starter is selected first. It is also important to use a limiter for the camera. All this will allow you to safely pour the mixture into the tank. Combs for such models can be used in various shapes. In this case, much depends on the capacity of the tank, as well as the power of the motor.

Models with chain drive

It is possible to make a do-it-yourself forced-action concrete mixer with a chain transmission only using a drive with a distributor. In this case, the tank is selected for 700 liters or more. The shaft is directly installed in the central part. To fix it, you need to make a solid bed. Most often, steel profiles are used for this purpose. If we consider the usual modification, then the starter can be selected manual type.

In this case, the suspension near the box is mounted on bearings. The frame should directly rest against the side stops. For better stabilization of the structure, partitions are welded near the chamber. The motor in the mixers must be located at the bottom, away from the feed opening. The gearbox for assembly is selected worm. It connects to the shaft through a pulley. The combs for these mixers are mainly taken of a curved type. All this allows you to successfully work with mixtures of high viscosity.

10kW Concrete Mixers

10 kW forced-action concrete mixers allow you to safely use 600 liter chambers. In this case, it is important to install the comb with small blades. To start assembling the structure, a frame for the tank is prepared. You can even make it from metal profiles. In order to increase the stability of the mixer, many experts advise soldering partitions on the sides of the structure.

Directly, the central shaft must be attached after fixing the camera. The loading cover for these devices can be made in various widths. Drives to the mixer are selected only crank type. The suspension will be required in turn with a loop. Due to this, the shaft will rotate clearly around the axis. Directly the 10 kW electric motor must be connected to a manual starter. At the end of the work, it is important to install the safety clutch.

12 kW model

You can install a chamber of 700 liters on a self-made forced-action concrete mixer of 12 kW. In this case, the starter is alloweduse manual type. However, models with electronic modifications are quite common. The frame for assembly must not be installed at a high height. All this will allow you to place the crank drive without any problems. Many experts recommend choosing a suspension for a mixer with a loop. In order to fix the limiter on the shaft, a welding inverter is used. In this case, the gearbox can be used worm type.

Modifications for 15 kW

They make 15 kW forced-action concrete mixers with both vertical and horizontal chambers. If we consider the first option, then the capacity can be safely selected for 70 liters. In this case, the comb can be used with large blades. Also, some experts in the tank solder the steel plates at a low angle. All this is allowed to knead mixtures of high viscosity. At the same time, you can work with concrete of any brand.

A wide rack is used to secure the container. In this case, the loading cover for the model is not required. Actuators are mainly used with distributors. In this case, electric motors are connected with a gearbox. If we consider modifications with a horizontal arrangement of the tank, then the drive is selected crank type. In this case, it is better not to use combs with blades. In order to avoid a heavy load on the frame of the device, the side racks on the partitions are soldered. After fixing the central mixing shaft, it is installed by an electric motor with a gearbox. The next step is to choose a limiter for a comfortableloading mix.

Conventional Disc Concrete Mixer

Discs are generally used in high capacity mixers. In this case, the tanks are usually installed in a vertical position. If we talk about the standard manual model, then it is more expedient to select a steel frame. The handle itself must be away from the barrel. The loading chamber is made in the central part of the tank. All this allows you to evenly distribute the load on the mixer.

Modifications with guides

Guided forced-action concrete mixers are generally used on large construction sites. These devices are designed to work with dry mixtures. Electric motors for them are selected on average by 15 kW. In this case, drives are used both crankshaft and worm type. In some modifications there are distributors. If you are assembling a model with guides, you should first fold the frame. In this case, the side stops should be wide so that the tank with the mixture does not tip over.

Devices with manual starter

Compulsory concrete mixers with manual starters are in high demand today. They are installed under engines of various capacities. If we consider a modification of 12 kW, then a rotary box will be required to assemble the device.

Directlythe stator is connected to the output drive. The worm mechanism is selected based on the dimensions of the shaft. If we talk about devices with belt drives, then you need to use a distributor for assembly.
