See also crusher for mechanisms producing larger particles. In general‚ grinding processes require a relatively large amount of energy; for this reason‚ an experimental method to measure the energy used locally during milling with different machines was recently proposed.

Finite State Machine A Finite State Machine (FSM) is a kind of digital circuit‚ (and‚ possibly‚ other types of machines‚ including virtual ones) that is used to process information in steps (states). At every state a different part of the information can be processed. This has many advantages in terms of reduced hardware requirements over combinational logic networks (CLNs). It is a mathematical model of computation used to design both computer programs and sequential logic circuits. It is
