How does a concrete mixer with self-loading
The construction of an automatic concrete mixer is represented by a compact machine on self-propelled chassis. On them there is a concrete mixer and a loading box. The size of the device is not very large and is about 150-200 liters, and the speed of the chassis is no more than 5 km / h. The productivity of the device is about 150 cubes of solution for a two-barrel barrel and slightly more than 100 cubes for a 150-liter barrel.
The entire process of preparing concrete is fully automated, and the conformity of proportions of concrete components is monitored by the computer system. However, you can not do without an operator, it is necessary to monitor the entire process and timely implementation of tasks. The mixture will be ready in 20 minutes. For placing concrete in hard-to-reach places, a rotating drum is provided that rotates around the axis.
How to prepare a concrete mix with a concrete mixer
Despite the fact that the process is automated, there is some order of solution preparation.
Step 1: water supply
Water is supplied first, so make sure that the liquid is in the machine before loading the dry components.
Step 2: Loading
materials A bucket of the necessary amount of raw material for the concrete solution is poured out through the guide hopper into the drum. The work is done by the operator's command. To place the mixture, you do not need to print the bags, since there is a special crest on the ladle for this. Dose mixture is determined by the system, which eliminates the possibility of error in proportions.
Step 3: Mixing the raw material
All components are mixed with the unit, and as a result, you get the building concrete of excellent quality. Once the solution is ready, it can be discharged into any available container in two ways: standard and accelerated. According to the standard type, concrete is pushed out by rotating the drum on its axis and turning it to the location of the container. By the quick type: the drum rises above its level by half a meter and tilts to the container along the level of its flanks.

The difference between professional and household mixers
Builders often face the choice of which concrete mixer is better for repair, what benefits and advantages it has, depending on price variations.
It is worthwhile to understand that the professional device has a larger volume, the size of the drum, is made of high-quality kinds of metal with various protective coatings. The motor power of the unit, as a rule, should be such that it can work for at least 12 hours without interruption.
Classic drum capacity: 200 liters. If less, the device becomes less profitable and more expensive to operate. At the same time there are concrete mixers and less than 100 liters, and more than 300.
For professional units, there is the presence of large drums with internal rotation of blades that mix the solution. These they allow you to create a variety of solutions, especially those designed for laying pavers.
The main drawback of professional devices: the impossibility of mixing the solution with gravel and crushed stone.
If you still need to prepare such a mixture, use gravity concrete mixers that allow mixing the ingredients in a spinning drum with blades that do not rotate but hold the solution at the walls during its mixing.
How to choose a professional concrete mixer
For household needs, you must choose a device that works from the network, but does not overload it. For a professional unit, you must connect a different power source."Home" devices can prepare up to 200 liters of concrete, while professional devices can up to 1000 liters per connection.
Pay special attention to the drum, which must be so thick as to mix the compound with a large mass and at the same time such that it can be moved around the territory( ie it must be mobile).Remember that the entire volume of the drum is not intended for absolute filling, a third must be empty so that the components can be freely mixed.
The last recommendation: choose models of well-known manufacturers and do not spare your wallet, since you always have to pay for quality.

We hope that your choice will not upset you, but the way you use the device will please for many years.
