In the cement production process, in order to ensure the smooth progress of the production process, loose materials such as: broken limestone, cement raw material, cement clinker, different types of cement and mixed materials (fly ash, granulated blast furnace slag), etc. Storage is necessary, and the storage capacity is also large. For powdery loose materials, such as raw cement, finished cement, pulverized coal and ground slag, almost all are stored in silos. The homogenization silo is a cylindrical single or multi-silo silo, large silo and round storage. It has been proven to effectively store granular loose materials, clinker and broken limestone, as well as powdery loose materials. Such as cement, cement raw meal or fly ash.

Homogenization refers to the process of reducing the fluctuation amplitude of the chemical composition of the material and making the chemical composition of the material uniform through the use of one-step process measures. The purpose of homogenization using the homogenization warehouse is to ensure the quality of clinker, the basic measures and prerequisites for reducing consumption, and it is also an important way to stabilize the quality of cement. The main structure of the raw meal homogenization silo is composed of a top distributor, an inflatable tank in the silo, a discharge device at the bottom of the silo, an inflatable metering silo, a load cell, a manual gate valve, a pneumatic switch valve, an electronically controlled pneumatic flow valve, and an inclined conveyor. It is composed of tank and air-filling pipeline system and accessories inside and outside the warehouse.

Homogenization of raw meal: The process of making the raw meal after grinding into a uniform composition through reasonable collocation or pneumatic stirring. The homogenization of the raw meal adopts air stirring and the action of gravity, which produces a "funnel effect", so that when the raw meal powder is discharged downward, it is possible to cut multiple layers of material and mix it fully. The use of different fluidizing air causes the parallel material surfaces in the silo to have different sizes of fluidization expansion, some areas are unloaded, and some areas are fluidized, so that the material surface in the silo is tilted for radial mixing and homogenization. The homogenization warehouse should meet the requirements of raw meal homogenization and unloading.
