Currently used to store cement storege silo has become the dominant direction, not just because of the steel plate welded repository to save money, shorten the construction period, and easy clean-up and removal.

Cement silo storage in the form of:
       Cement repository is in the library and other locations based on the conical bottom of the mixing chamber to reduce the discharge pressure of the inside of the funnel flow silo elimination. A mixing chamber located feeder holes 8-12, 8-12 is provided in the inflatable region of the mixing chamber and the annular region between the base wall, the relative rotation of the annular discharge cell is inflated, so that the mixing chamber toward the central part of the cement. In the top-down flow process, the cutting level of the material layer to generate mixing action of gravity, into the mixing chamber silo after the pneumatic mixing chamber for continuously stirred further homogenized. This library homogenized value of up to 5-9. Power consumption 0.15-0.30kwh / t.

After absorbing surface hydration of cement particles, cement powder is highly absorbent body material. The more fine cement mill. Adhesion greatly increased, decreased mobility, easy crust, bagging. Therefore, cement silos should be strictly controlled moisture intrusion. Cement silo moisture intrusion into the cement itself, rainwater infiltration and climate aid flow disassemble into three types, you can probably take the following to be addressed another way.

Clinker reservoir conditions relatively perfect, try adding a cement themselves into the water. For medium-sized libraries in terms of fly ash cement plant. Clinker into the water Shaoshao. Confused timber drying moisture control less than 1% of cement in the water storage is less than 0.5% of individuals less dangerous. For small cement plant in terms of clinker storage conditions are poor, mostly plant clinker open dumps, or water cooling, with a portion of the water into the mill clinker. Since most of the plant's drying equipment is imperfect, so that water into the mill admixture exceeded, especially the production of fly ash cement kiln plant, fly ash drying moisture 25% and some more to make cement According to the survey is much larger than 1% moisture content, moisture absorption part kiln plant library library cement fly ash up to 5% larger library cement water, surface hydration of cement particles first, with fully gelling, greatly adds adhesion, which is an important cause of small cement plant cement silo knot arch. Recommend revisions to the competent authorities "moral cement kiln management procedures" in the entry of moisture on the material, minimizing drying moisture of the material. Cement kiln drying system they should improve one's strength and clinker repository, try to add to cement themselves into silos of water content.

This is very rare in the region south of the Yangtze more rain. Therefore, the two put an end to rain penetration. Because rainwater infiltration make cement silo crust, caking, bagging. Cement silo seepage another way to take more and more important. For brick kiln factory silo, because seepage crust, knot arch situation even worse. Rainwater infiltration is divided into libraries and library top wall infiltration.

These Pneumatic flow aid disassembly must spend a certain number of shortening the atmosphere, however. The compressed air dehumidification and rigid often not valued by the people. Aid flow from the broken arch demolition action, and shorten the amount of moisture into the atmosphere of another part of the water, so that the local cement water content increased adhesion to increase, adding to the agglomeration, knot arch can perhaps, therefore, must fulfill rigid and dehumidification to shorten the atmosphere.
