Comminution Theory & Process Equipment

Whether grinding is to be performed wet or dry, or in a ball mill or rod mill, a choice must be made between open or closed circuit. Other factors which require thought are mill size, speed of mill rotation, moisture content, retention time, circulating load, type and sizes of grinding media, mill pulp level, mill shape, power, and relation ...

A survey of control and economic concerns

Closed circuit dry grinding using ball mills is essential in mineral processing industries. This process is characterized by significant dead times, highly coupled variables, limitations by operating ranges and complex modeling, making it difficult for classical controls to obtain fast responses with low overshoot.
