Concrete mixers of gravitational and forced action on construction sites are very popular. The parameters of the model are quite different. If we consider forced-type devices, we can observe the following: all of them can work with concrete of different brands. They are often used to mix refractory solutions.
Also, these devices are suitable for the preparation of finishing mixtures. However, their advantages do not end there. With high viscosity adhesive mixtures, they cope perfectly. For example, you can mix the plaster. On average, a new forced-action concrete mixer (market price) costs about 60 thousand rubles.
Modifications with a horizontal camera
A device with a horizontal arrangement of the chamber (forced-action planetary mixer), as a rule, is made with electric motors. Directly starters are manual type. The kneading plates are quite wide. Thus, the performance of such devices is high. Also, a distinctive feature of the model can be called the presence of a cranked 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 mounted directly on 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
Devices with vertical cameras (forced-draft concrete mixer drawings 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 on 400 liters. It is more expedient to select a steel frame. A long stand is used to secure 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
Making a forced-action concrete mixer with a belt drive is quite simple. First of all, a reservoir is taken for the model. In some cases, use an ordinary barrel. 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 with the installation of the central shaft. In this case, the drive will require a cranked type. It can be used with a broken concrete mixer. A belt-type gearbox is installed next to the engine. In order to fix it, a small metal platform is made.
The motor should ultimately not come in contact with the frame. In order to install the gearbox, the starter is selected first. It is also important to use a stopper for the camera. All this will allow you to safely fill 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.
Chain Drive Models
Making a forced-mix concrete mixer with a chain drive is possible only with the help of a drive with a distributor. In this case, the tank is selected for 700 liters or more. Directly the shaft is installed in the central part. To fix it, you will need to make a strong bed. Most often, steel profiles are used for this purpose. If we consider the usual modification, then the starter can be selected manually.
In this case, the suspension near the box is mounted on bearings. The frame itself must abut against the side stops. For better stabilization of the structure, partitions are welded near the camera. The motor in the mixers must be located at the bottom, away from the loading hole. The gearbox for assembly is selected worm. It connects to the shaft through a pulley. The combs for these mixers are mainly of a curved type. All this allows you to successfully work with mixtures of high viscosity.
10 kW concrete mixers
10 kW forced-action concrete mixers make it easy to use 600-liter chambers. In this case, it is important to install the comb with small blades. To start the assembly of the structure, a frame is prepared for the tank. You can even make it from metal profiles. Many experts, in order to increase the stability of the mixer, advise soldering partitions on the sides of the structure.
The central shaft itself must be mounted after securing the camera. The boot cover for these devices can be made of various widths. The drives to the mixer are selected only cranked type. The suspension will be required in turn with a loop. Due to this, the shaft will rotate clearly around the axis. Directly, a 10 kW motor must be connected to a manual starter. At the end of work, it is important to install a safety clutch.
12 kW model
On a homemade forced concrete mixer 12 kW, you can install a chamber of 700 liters. In this case, the starter is allowed to use the manual type. However, models with electronic modifications are quite common. The assembly frame needs to be installed not high. All this will allow you to easily place the crankshaft. Many experts recommend to choose a suspension bracket for the mixer with a loop. In order to fix the limiter on the shaft, a welding inverter is used. In this case, the worm gearbox can be used.
15 kW modifications
They make forced-use concrete mixers of 15 kW with both vertical and horizontal arrangement of the chamber. If we consider the first option, then the capacity can be selected safely to 70 liters. In this case, the comb can be used with large blades. Also, some experts in the tank solder steel plates at a small angle. All this allows kneading mixtures of high viscosity. In this case, concrete can work with any brand.
A wide rack is used to secure the container. In this case, a boot cover for the model is not required. Actuators are mainly used with valves. Electric motors are then mounted with a gearbox. If we consider modifications with a horizontal arrangement of the tank, then the drive is selected cranked type. In this case, comb with blades is better not to use. In order to avoid a large load on the device frame, 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 convenient loading of the mixture.
Conventional Disc Concrete Mixer
Discs are typically used in large capacity mixers. In this case, the tanks are usually installed in an upright position. If we talk about the standard manual model, then it is more advisable to choose a steel frame. The handle itself must be kept away from the barrel. In this case, a 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
Forced concrete mixers with guides are typically used on large construction sites. These devices are designed to work with dry mixes. Electric motors for them are selected on average by 15 kW. In this case, the drives are used both cranked and worm type. In some versions there are valves. If you are assembling a model with guides, you should first fold the bed. In this case, the side stops should be wide so that the tank with the mixture does not tip over.
Manual starter devices
Forced-action concrete mixers with manual starters are very much in demand today. They are installed under engines of various power. If we consider the modification of 12 kW, then to assemble the device you need a rotor box.
The stator is connected directly to the output drive. The worm gear is selected based on the size of the shaft. If we talk about devices with belt transmission units, then for the assembly you need to use a distributor.
