A novel controller for coal circulation and pulverized coal flow in a coal mill is proposed.The design is based on optimal control theory for bilinear systems with additional integral action.
A practical approximation to the fundamental integro-differential equation for batch grinding is presented and a solution developed.The solution is written in terms of two experimentally determined basic parameters of the system, (1) rates of breakage and (2) breakage function, and is in a form suitable for simple extension to describe continuous grinding systems.
A set of questions at the end of each chapter helps to connect theory with practice, and an accompanying solutions manual is available to instructors.
