In recent years, the new dry-line infrastructure investment has been rising, affecting the economic benefits after the project. There are many reasons for the gradual increase in funding, such as capital contribution, construction engineering, equipment costs, and cement equipment installations. However, the status of planning factors that result in the addition of funding cannot be ignored. In the planning process of the cement plant, based on many inductive elements such as materials, sites, funds, etc., the new dry-line equipment investment was reduced from the planning point of view, and the trapezium mill was determined to be the medium-speed T-type. Mill process technology skills Cement system equipment is very important.
Grinding is an important skill process for cement production. It not only determines the unit power consumption of cement production, but also has an important impact on cement function. For a long time, the trapezium mill process skill cement clinker grinding is carried out in a ball mill through the medium-speed T-type grinding price. The ball mill has strong adaptability to materials and is easy to adjust the fineness of the milled products; the equipment is simple in structure, reliable in operation, convenient in handling and so on. However, the effective utilization of energy is low, only 2% to 5%. In the past ten years, the cement grinding skills have been greatly developed. The traditional mill has been improved, and high-efficiency powder selection equipment has been adopted. Vertical mill and kneading mill have also been used one after another, which greatly reduces the energy consumption of grinding and improves the grinding power of the trapezium mill process. .

The rationality of the placement of the powder chamber in the trapezium mill is very important. The material is sorted by inertia force, gravity and vortex flow in the powder selection chamber to make the coarse and fine particles fully separated. The spatial scale selection is more reasonable, which makes the powder selection power significantly improved and the energy consumption is reduced.
The rotor system in the process of the trapezium mill is easy to condition. Because the motor speed of the powder separator and the number and angle of the small blades and the auxiliary blades are adjustable, the system parameters can be matched to reach the aspiration state, and the grain size of the product is easy to be adjusted.
Because of the improvement in grinding skills, it also has a certain impact on the characteristics of cement particles. Therefore, it is necessary to study the process of dissecting the process of trapezium mill and the change of the role of medium-speed T-type grinding, so that the improvement of skill equipment and the optimization of operating parameters can reach energy saving, consumption reduction and cement function improvement. Inductive effect.
