With the increasing consumption of resources in China, resource reserves have fallen sharply. To this end, China has promulgated various policies to promote the implementation of China’s sustainable development strategy. For the treatment of large quantities of slag in the mining industry, many companies use slag as raw materials to process cement and other new energy sources. Vertical mill slag powder equipment plays a key role in the processing of slag.
The application of the vertical grinding slag micropowder technology makes the processing of slag more elaborate. In the cement manufacturing production process, the slag is used as raw material to realize the recycling of waste and reduce the pollution of the slag to the environment. The vertical mill is mainly used as the main grinding equipment in the slag production line. In addition to vertical grinding, customers can also choose other auxiliary equipment, such as feeders, vibrating screens, etc., to make the slag production line process more complete.
With the gradual improvement of the research and development technology of the mill, the vertical mill technology of the foreign mill manufacturers is more and more mature, and the product technology advantages of the vertical mill are also increasingly prominent in many milling equipment. Domestic mill manufacturers have learned from foreign successful experiences and carried out major technological reforms. They have re-launched vertical mill products with their own related technologies, and gradually accepted them for the domestic cement, electric power and chemical industries, and become the ideal equipment for industrial grinding. .
In the vertical grinding slag production, vertical grinding has the following technical advantages. The first is that the vertical grinding uses the principle of material layer grinding to grind the material with low energy consumption. The energy consumption of the vertical mill system is 30% to 40% compared to the ball mill system. Vertical grinding does not have the metal impact of the ball in the ball mill colliding with each other and hitting the liner, so the noise is small. Secondly, the vertical mill adopts a fully enclosed system, and the system works under negative pressure, which reduces the pollution of the dust to the environment. At the end of the day, the vertical mill uses hot air to transport materials. When the material with large moisture content is ground, the inlet air temperature can be controlled to achieve the desired final moisture. It can be dried in the vertical mill to grind into the material with the moisture up to 15%~20%.
