In the huge system of cement production, the material transportation link is like the blood vessels of the human body, which runs through the whole process and is crucial. Cement materials have the characteristics of high particle hardness, large conveying volume, and long conveying distance, which places extremely strict requirements on the conveying pipeline. Alumina ceramic pipes came into being under such a background, so what unique advantages does it have in cement transportation?
From the perspective of wear resistance, alumina ceramic pipes can be called "wear-resistant masters". Its inner wall is made of high-purity alumina ceramic material and is sintered at high temperature. This ceramic material has extremely high hardness, with a Mohs hardness of about 9, which is far higher than ordinary steel materials. During the cement transportation process, cement particles continue to scour the inner wall of the pipe, and ordinary steel pipes may suffer severe wear in a short time, resulting in wall thickness reduction, leakage, and other problems. The alumina ceramic pipe can effectively resist the wear of cement particles with its hard inner wall, and its wear resistance is 5-10 times that of ordinary steel pipes. For example, in a cement clinker conveying pipeline, when ordinary steel pipes are used, some severely worn pipe sections need to be replaced every year. After using alumina ceramic pipes, the service life of the pipes is extended to more than 5 years, which greatly reduces the maintenance cost and downtime for maintenance.
In terms of conveying efficiency, alumina ceramic pipes also perform well. The surface of its ceramic lining is smooth, and the roughness is only 1/5 - 1/10 of that of steel pipes. This greatly reduces the resistance of cement materials when flowing in the pipeline, and can be conveyed at a higher flow rate. According to actual tests, under the same conveying pressure, the flow rate of cement conveyed by alumina ceramic pipes can be increased by 20%-30 % compared with ordinary steel pipes. For large-scale cement production companies, this means that they can increase the conveying volume of cement and improve production efficiency without adding too much power equipment.
In addition, alumina ceramic pipes have good high temperature resistance. In cement production, some high-temperature materials such as cement clinker and high-temperature gas need to be conveyed through pipelines. Alumina ceramics can maintain stable physical and chemical properties in high-temperature environments above 1000°C, and will not deform, soften or be damaged by high temperatures. This enables alumina ceramic pipes to safely and stably transport high-temperature cement materials, ensuring the continuity of the production process.
At the same time, alumina ceramic pipes also have a certain degree of corrosion resistance. During the cement production process, the material may contain a small amount of acidic or alkaline substances, which will cause corrosion to the pipe during long-term transportation. Alumina ceramics have strong corrosion resistance to most acidic and alkaline substances, which can effectively prevent the pipeline from leaking due to corrosion and extend the service life of the pipeline.
In the complex and critical link of cement transportation, alumina ceramic pipes provide cement companies with reliable and efficient material transportation solutions with their unique advantages such as excellent wear resistance, efficient transportation capacity, good high temperature resistance and corrosion resistance, and become an indispensable and important equipment in cement production.
