Low noise and little powder dust. In the working process of Application of Raymond Mill, the grinding sound is soft, often about 80 db. The grinding roll and the grinding disk does not contact with each other. Vertical mill adopts integrated sealing, and the system works under negative pressure, so the powder dust is little.

Even final products. The qualified products inside the vertical mill can be timely discharged, thus avoiding over grinding and the product granularity is even. Grinding is an important technical link in the production of cement, as it not only determines the unit electricity consumption of cement production, but has great influences on the performance of cement. For a long time, cement grinding is completed inside ball mill as it has the features of simple structure, reliable operation, convenient maintenance and management, strong adaptability for the materials, continuous production, big production capacity, big grinding ratio and easy control of the fineness of the final products.

However, the effective energy availability is only 2%-5%, and the majority of the rest energy is changed into heat energy, and the economic benefits are not optimal. In recent years, traditional grinding mill is improved and updated, and new type of powder separation closed-circuit system is adopted and the cement grinding technology is developing rapidly. Especially the application of vertical mill greatly reduces the energy consumption of grinding slag cement and improves the grinding efficiency.
