Difference between Crushing and Grinding

According to this, if we now further crush down to diameter z the additional work done is Q (1/z – 1/y), and the total work done in crushing from diameter x to diameter z = Q (1/y – 1/x) + Q (1/z – 1/y), which = Q (1/z – 1/x), the same as if the crushing were all done in one operation. To make the computation, then, it is necessary to determine the ...

Mill (grinding) - Wikipedia

A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand or by animals (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().
