The significance of setting the cone angle is revealed by analyzing the relationship between the stator cone angle of annular gap mill (AGM) and the intensity of materials being abraded The simplified model of motion and that of dynamics have been established and the cone angle of stator arrived at.

In order to make annular gap mill to work steadily at the best state,promote its running stability and efficiency, a control strategy is proposed based on mathematical models of annular gap mill, which combines ordinary control system with dynamic self optimizing control system.

The method of combining theory and experimentation is used to study the law of movement and characteristic of receiving force of the medium - balls in annular gap mill.

This paper mainly introduces the structural characteristics of the annular gap affritor,a machine for producing super-fine powder.

Annular Gap Affritor, known as "Mill in 21st century" , is a kind of mill introduced by WUST in 1980 s.

The paper analyzes the present situation of annular furnace,discusses the optimum design scheme of large scale annular furnace from construction of furnace,distribution of heat,selection of burner and refractory,ascertainment of annular gap,and so on.

The principle of Bitchoff annular gap sealing of 6# blast furnace of Wuhan Iron & Steel Co.
