I. Introduction.
The raw meal homogenization library is an important part of the cement production process, and its main function is to homogenize the raw materials to ensure the stability and product quality of the subsequent production process. However, due to various reasons, the raw meal homogenization library may be blocked, crusting and other phenomena during use, which affects the homogenization effect and the normal operation of the production line. Therefore, it is very important to clean and dredge the raw meal homogenization warehouse in time. This article will introduce in detail the methods, precautions and preventive measures for cleaning and dredging the raw meal homogenization warehouse.

2. Analysis of the causes of blockage in the raw meal homogenization warehouse.
The main reasons for the blockage of the raw meal homogenization warehouse include: fluctuation of raw material composition, high water content, high temperature in the warehouse, uneven distribution of air flow, rough inner wall of the warehouse or hanging materials, etc. These factors may lead to crusting and blockage of raw materials in the warehouse, which seriously affects the homogenization effect and the normal operation of the production line.
3. Cleaning and dredging method of raw meal homogenization warehouse.
1.Manual cleaning and dredging.
For small raw meal homogenization warehouses, manual cleaning and dredging methods can be adopted. The specific operation is as follows: close the infeed and discharging valves, empty the materials in the warehouse, and use a steel drill or hammer to knock on the inner wall and pipeline of the warehouse to loosen the blockage. At the same time, use a steel brush or shovel to clean up the loose blockage and keep the pipeline and the inner wall of the warehouse unobstructed.
2.Mechanical cleaning and dredging.
For large-scale raw meal homogenization warehouses, the method of mechanical cleaning and dredging can be adopted. The specific operation is as follows: insert the pipe into the blockage part of the warehouse, and use mechanical force to clean out the blockage. Commonly used mechanical cleaning equipment includes pipeline dredging machines, hydraulic dredging machines, and compressed air dredging machines.
Fourth, the cleaning and dredging precautions of the raw meal homogenization warehouse.
1.Safety first.
In the process of cleaning and dredging the raw meal homogenization warehouse, safety should always be put first. Due to the possible presence of flammable and explosive gases in the warehouse, the use of open flames and sparks should be avoided. At the same time, in the process of cleaning and dredging, attention should be paid to avoid sudden rupture of pipelines and equipment, so as to avoid personnel and environmental pollution.
2.Prevention.
In order to reduce the blockage of the raw meal homogenization warehouse, preventive measures should be taken. Regularly spray anti-hanging coating on the inner wall of the warehouse, keep the temperature and humidity in the warehouse stable, control the flow and speed of feeding and discharging, and regularly inspect and maintain pipelines and equipment. These measures can effectively reduce the occurrence of blockage and improve the stability of the production line and product quality.
V. Conclusions. The cleaning and dredging of the raw meal homogenization warehouse is an indispensable link in the cement production process. By understanding the cause of the blockage and taking appropriate cleaning and dredging methods and preventive measures, the normal operation of the raw meal homogenization warehouse can be ensured, and the stability of the production line and product quality can be improved. In actual operation, appropriate cleaning and dredging methods and preventive measures should be selected according to the specific situation, and the safety operation procedures should be strictly adhered to to ensure the safety of personnel and the stable operation of the production line. At the same time, strengthening equipment maintenance and inspection, and finding and solving potential problems in a timely manner is also an important guarantee for improving production efficiency and product quality.
