Fly ash is an industrial waste discharged from thermal power plants and belongs to pozzolanic active materials. It contains more active silica, activated alumina, which reacts with calcium hydroxide at room temperature to form stable hydrated calcium silicate and calcium hydrated calcium aluminate. These components contribute to the hardening of the mixture and increase strength. In addition, fly ash is a spherical molten powder, and the particles are glassy, the particles mainly have two types of minerals: one is glass and about 70% to 80%; the other is crystalline, about 15%~20%. These spherical particles are the main reason for the improved workability of the mixture. Highway engineering uses fly ash to build roads, which can not only reduce waste into treasure, but also reduce the pollution of road materials and improve the quality of roads.
The wide application of fly ash in various engineering projects makes the grinding equipment for processing fly ash, raymond mill, more popular with the owners of major fly ash manufacturers. In the years of practice and continuous improvement, Kefid has a unique advantage in the design and production of raymond mill, and its equipment structure has been improved. When grinding fly ash, because the whole machine is three-dimensional structure, it is systematic and can be a self-contained production system. The finished product has a uniform fineness, the wear-resistant parts of raymond mill are made of high-quality steel and are made of high-performance wear-resistant materials for reliable operation. This equipment has become a new choice of equipment for waste utilization because of its low dust pollution, low noise, small size, easy adjustment, and easy maintenance.
