The ultrafine vertical mill is simple and compact in structure and high in reliability, and it is an important grinding equipment in metallurgy, chemical industry, cement, ceramics, construction, power and other fields.

However, the shortcomings of ultrafine vertical mills are obvious, that is, high energy consumption and high iron loss. In recent years, with the increase of energy and the decline of energy quality, energy saving and consumption reduction have become a hot spot in ultrafine vertical mill research.

At present, the measures of energy saving and consumption reduction of ultrafine vertical mill mainly focus on the improvement of structure, optimization of working parameters and automatic control.

Compared with medium and small mills, the advantages of large mills are that they can save construction cost, operation and maintenance cost, simplify the equipment configuration and automation requirements. However, the energy consumption per unit of large mill is higher than that of small and medium mills, so the development of specifications is limited.
