Unloading of cement - mechanism of action, types of unloading, loading.

Cement is a specialized technique that provides бестарную transportation, transportation of cement factories, warehouses at a construction site. As for unloading cement, there are some ways by gravity and пневморазгрузка, and loading is gravity and air. Unloading of cement by gravity. So, gravity load acts as if gravity. For such a load is typically used specially designed sleeve. It is connected to the top manhole, which is on the cement drive, and material (cement) poured himself thus in the tank. Unloading of cement according to the method of «gravity» is due to the fact that the axis of the tank leans a few degrees (7 - 9), and also due welded to the side, again at some angle (usually - 45 or 50 degrees). Cement same under its own weight, and also under the influence of the known all gravity comes to the exit, and just unloaded. So, the unloading of cement is a rather simple process. That process was somewhat faster, the tank is typically equipped with special spare parts - vibrators.  Cement trucks belonging to this type, do not differ very high price, but have some disadvantages. For example, during unloading and loading operations cement «dusty». Importantly, during this process a small amount of cement remains at the bottom of the tank, and these residues can be removed manually.

Unloading of cement, and their loading is possible and pneumatic method, which we now examine. Pneumatic unloading is as follows. All the matter is that the cement carrier is equipped with a rotary compressor, влагомаслоотделителем, collector, and a pressure gauge and a special system of воздухоотходов equipped with check valves and ball valves. It is due to all this technology and is unloading of cement. In the process of unloading in the tank includes a number of air, thus creating pressure (up to two atmospheres) and open the taps. So, faucets there is a unloading of cement. Air blows it. And the unloading of cement pneumatic method. With regard to пневмозагрузки, here is used all the same equipment. But downloading all of this equipment is aimed at creating in the vacuum tank. This way is very popular and actual in modern times. The technique, which is equipped with a pneumatic system, should, of course, more expensive than the gravitational analogs, but this is quite fair, because the pneumatic system operates much more efficiently and with better quality in work.

As for the maximum weight that can be carried by the cement carrier, the decisive role played by rules of traffic police. As a rule, the capacity of any cement is much more than its weight. For example, the capacity of the cement weight of 14 tons, up to 40 tons. If the load in such a cement carrier to the maximum, then the movement is not very safe for your person, and for the other traffic participants. Maximum weight of transport, moving on the highway 38 tons. So if you exceed this limit, then unloading cement () can happen very soon, on a post of traffic police. In fact, regardless of the tank's capacity, you can download only 24 tons of cement.

So, we figured out how to unload cement and download, dismantled the types of downloads (discharges). We hope that this material will be useful to you.
