Concrete mixing plant has higher requirements on the quality stability of cement. Powder silo is a kind of main equipment used to store bulk cement or other powder materials. It is usually combined with mixing machinery and batching machinery to form various types of mixing plants.

Work, use bulk cement vehicle first cement or other powder charge transport in the body, open the unloading door, powder and through the gate into the screw conveyor, and then is continuously measured to powder in the weighing hopper. The powder bin is mainly composed of the storage part, the broken arch system, the dust removal system, the unloading device and the base frame. Concrete is a kind of heterogeneous complex composite material, which can improve the strength and durability of concrete. The cement used in the concrete mixing station is bulk cement, which is stored in small powder bins such as 100t or 200t. Because of the impurities such as caking, bolt, cloth and grinding ball in cement, it will seriously affect the normal use of the mixing plantand the homogeneity of the concrete, thus causing the quality of the concrete to decrease.

Because bulk cement controls the quality of cement in the process of production, especially the stability of 100 %, ensures the quality of cement production. In the process of transportation, bulk cement trucks are used to be delivered directly from the cement factory to the users, and the circulation channels are clear and clear, so as to prevent adulteration or shoddy work, thus guaranteeing the stability of transportation quality. In the process of storage, bulk cement does not deteriorate in a normal storage tank for 13 months; In the process of use, the cement measurement is accurate and without loss, which ensures the accuracy of cement consumption, and ensures the quality of concrete and engineering. So bulk cement can be widely used. But because the cement itself is very strong water imbibition, powder and granular materials the fine cement mill, the stronger water imbibition, hydrated cement particles after absorbing water surface, to increase adhesion, mobility, easy to wriggle through the earth crust, and even caking. Cement agglomerate or cement storage, exists in gypsum, alkali oxide in water gradually formed potassium gypsum, stored in the hanging wall of phenomenon, is the cement and condensed water caused by hydration, therefore, should strictly control the moisture in the cement silo. There are three types of water intrusion in cement silo including cement itself, rainwater infiltration and air flow device. Along with the application of bulk cement, due to a long, long time of storage and transportation, cement agglomerate phenomenon has become so common that it can happen in cement plants, can also occur after delivery of the transportation, storage, etc. In the process..
