• Grinding in Ball Mills: Modeling and Process Control

The design of a ball mill can vary significantly depending on the size, the equipment used to load the starting material (feeders), and the system for discharging the output product. The size of a mill is usually characterized by the ratio “length to diameter” and this ratio most frequently varies from 0.5 to 3.5. The starting material can be loaded either through a spout feeder or byResearch of Mathematical Model of the Ball Mill ,From the operation mechanism of the ball mill with double inlets and outlets, this paper gives a research work to the simulation of the ball mill with double inlets and outlets, and proposes a corresponding mathematical model of the six controlled with six control variables of the ball mill with double inlets and outlets, and simulates with Matlab using the operation data of a power plant.
