The invention relates to an experimental system and a method of ore grinding process control, and belongs to the technical field of automatic control. The system comprises an operation optimization control device, a process loop control device, and a three-dimensional virtual ore grinding process operation device, wherein the three-dimensional virtual ore grinding process operation device comprises a virtual object operation device and a three-dimensional visualization operation device, new software and hardware technologies and simulation technologies are used on the process loop control device to enable the process loop control device in development and the three-dimensional virtual ore grinding process operation device to be as close as possible to a real industrial environment, and the process loop control device has good visuality and compatibility. The system further integrates the operation optimization control device, so that the problems that in the real industrial process, the loop set value is depended on human experience, arbitrariness is high, and decisions are unreasonable are solved. Therefore, the experimental system and the method of the ore grinding process control are good in versatility, strong in compatibility, and have three-dimensional visual effects. The experimental system and the method of the ore grinding process control are free from the restriction of a hardware device. The dynamic substitution between the optical control algorithm and the device model algorithm can be achieved, and the openness is good.
