Homogenization storehouse is a kind of cantilever cylindrical silo used to store powdery loose materials, which is a common construction form in storage. The homogenization library can be constructed separately or in combination. This warehouse form usually includes: the top of the warehouse, for the storage equipment; the silo, for the storage of loose materials; the bottom of the warehouse, below (above or below ground level) There are bottom unloading devices, conveying equipment and weighing equipment; the latter is the foundation of the silo.

Homogenization refers to the process of reducing the fluctuation range of the chemical composition of the material and making the chemical composition of the material uniform by adopting one-step process measures. Raw material homogenization: the process of making the raw material ingredients uniform after grinding through reasonable matching or pneumatic stirring. Adopthomogenizing libraryThe purpose of homogenization is to ensure the quality of clinker, which is the basic measure and prerequisite to reduce consumption, and also an important way to stabilize the quality of cement.

In the process of cement production, raw material homogenization is an important process link in the production of homogeneous chain, which plays an important role in improving the output of cement clinker and ensuring the stability of cement quality. Therefore, the design of the raw material quality homogenization library is directly related to the quality of the homogenization effect, whether it can ensure that the composition of the raw material into the kiln is highly uniform, and complete all the tasks of the whole raw material homogenization chain.

Some cement enterprises do not make full use of the homogenization efficiency of the raw meal homogenization warehouse, and only store it as raw meal, resulting in large fluctuations and instability of raw meal composition in the kiln, which seriously affects the performance of the rotary kiln and the safe and stable operation of clinker quality. Therefore, how to make good use of the existing equipment and facilities of the raw material homogenization library and fully tap the homogenization efficiency of the raw material homogenization library has become a problem we have to face.

Rawhomogenizing libraryNote the use of the following:

(1) The pneumatic valves and flow valves in each zone must be in good condition and flexible and adjustable.

(2) Every time the kiln is stopped, a single-zone blanking test must be carried out, that is, a fixed single-zone blanking, and it is judged how much the flow valve is opened to meet the normal feed rate of the kiln. If the full opening still cannot be reached, it must be dealt.

(3) During the operation, it is found that the blanking amount in the aeration zone is too small, and it must be handled in time to ensure that the blanking amount in each zone is consistent.

(4) The homogenization library should be diligent in management and solve problems found in time. The homogenization effect of the homogenization library, which has been neglected for a long time, is poor.

(5) The lower discharge structure of the homogenization warehouse is different, but as long as there are multiple discharge points, the homogenization effect can also be improved.
