Production of concrete in a concrete mixer - exploit the technique correctly

mixer Principle of operation - it is useful to know when buying

Special construction machinery, concrete mixer or concrete mixer called, firmly settled on building sites all over the world.Outwardly, it resembles a barrel with an open top, often delivered at an angle to the frame and rotating around its own axis.The drive can be manual, run by an electric motor or other transfer (in Mixer Truck).

Invented many such mechanisms.And their classification is conducted primarily by what principle of the mixer applied.In simpler mechanisms used gravity mixer: in a rotating drum are vanes, and the mixture was stirred because of them.

For more homogeneous compositions used forced mixing: the blades are driven by mixing the components inside the fixed drum.Mixers can be rotated continuously or intermittently be mobile or stationary, to prepare concrete (when up to 70 mm fraction) or solution (fines).

How to work with the concrete mixer - simple rules for

hardware store offers a large number of models of concrete mixers for domestic use and the construction in a private home ownership.All of these are rather simple, using gravity mixing principle (in the majority) and driven via a belt drive or a toothed crown iron from the electric motor.Average power consumption is about 700 watts.

All model variants are readily available at a cost.For proper operation of the issue of how to prepare the concrete in a concrete mixer, successfully solved all models.With an average drum volume of 160 liters of ready-mixed concrete output or standard solution is 2/3 or about a hundred liters.

But, as in any business, you need to know how to work with concrete mixer.First of all, follow the recommendations of use management.Do not change the recommended angle of inclination of the drum.Winning the increase in volume will be "compensated" deterioration in the quality of mixing and reduction of uniformity of composition, increasing time on his preparation and additional load on the motor.

To prevent premature failure, you need to follow the recommended continuous operation.As a rule, the use of asynchronous electric motors allow heavy-duty use under high load.

concrete mixer Production in own

Before how to mix concrete in a concrete mixer , you need to prepare the required amount of cement, sand and gravel required factionalism.It is desirable that the sand and gravel were clean - no additives clay and dust.The best granite or gravel.These conditions are important to follow to obtain a high-quality concrete.

Of course, you need a source of water flow, if possible, not mineralized, without salt and other typical additives.For proper preparation of concrete or mortar must first be mixed in the desired proportions of cement and sand in the dry state.This can be done in a separate vessel (a bath, trough, etc.) and then adding the composition to the drum mixer.

water is poured to the same in the right amount after filling the dry mixture.After stirring the resulting solution is added last rubble.The whole process is illustrated in the video mixer operation is shown here in actual construction.

It is equally important for the actual conditions of use of this technique to know, how to clean the mixer .In order to use the mixer repeatedly, it is necessary to wash after using a water jet or even pouring it into a bucket drum.You can add water with a lot of gravel and carefully twisting the drum to drain it.Gravel will take over the remnants of the solution.

not leave the solution in the drum.Harden, it would deprive the opportunity to work on.Removing uncured solution of the drum pretty hard.It is necessary to dismantle the mechanism of the mixer.Attempts clear solution without disassembly of the pieces can lead to deformation of the shaft and stop rotation of the drum uniformly.So the best way to preserve the device is ready for operation will maintain its purity mixer in between use.
