Description

Technical Field

[0001] The present application relates to the field of cement processing, and in particular, to a high-strength cement processing method and a processing device thereof. Background Art

[0002] As the foundation of building materials, the performance of cement directly affects the quality and service life of buildings. With the continuous advancement of modern construction technology and the increasing requirements for material performance in engineering projects, the strength, durability, crack resistance and other properties of traditional cement can no longer meet the needs of some high-end projects. Therefore, the research and development of high-strength and high-performance cement has become an important topic in the current field of building materials.

[0003] The traditional method of producing cement is mainly to mix, crush, grind, preheat, and burn raw materials such as limestone and clay to finally obtain cement clinker. However, the strength of cement produced by this method is limited, and it is easy to degrade in certain special environments (such as high temperature, high humidity, and corrosive environments). In order to improve the strength and other properties of cement, researchers have tried to add various admixtures and mixed materials to the raw materials, but this method often leads to increased production costs, and sometimes it is difficult to ensure the uniformity and stability of cement.

[0004] In recent years, with the continuous development of materials science and engineering technology, some new methods for producing high-strength cement have gradually emerged. These methods have significantly improved the strength, durability, crack resistance and other properties of cement by optimizing the raw material ratio, improving the production process, adding new admixtures and other means. For example, some researchers have added reinforcing materials such as alkali-resistant glass fiber and carbon fiber, as well as adhesives such as phosphates and silicates to the cement raw materials, which has significantly improved the strength of cement. At the same time, by precisely controlling parameters such as temperature, atmosphere and time during the firing process, the quality and strength of the clinker can be further optimized.

[0005] However, the existing high-strength cement processing process has high costs and poor temperature control, and there is a great need to improve the processing technology and processing equipment. Summary of the invention
