According to the main problems on the current domestic mill operations control process,the dynamic mathematical model of the volume of ore mill is set up.

Key links such as mill\'s feed qty control,mill\'s inlet water qty control and mill\'s grinding density of the system are explained in details.

The performance and design parameter of grinding mill used in mineral processing plant of Yongping Copper Mine is introduced in this paper.

Study on smooth start device with hydraulic slip clutch in a mill;

Development and Application of Liners for Cylinder of Mill;

By making a elastic dynamic model of a large mill in its starting, the paper analyzes the effect of smoothly starting time and accelerating pattern on the dynamic load of the mill produced in its smoothly starting, gives some correspounding calculation formulae, and draws the relative charac terstic curve by use of the Matlab.
