Mill (grinding) WikiMili, The Free Encyclopedia

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 (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().

Cement mill Wikipedia

A Ball mill is a horizontal cylinder partly filled with steel balls (or occasionally other shapes) that rotates on its axis, imparting a tumbling and cascading action to the balls. Material fed through the mill is crushed by impact and ground by attrition between the balls. The grinding media are usually made of high-chromium steel.The smaller grades are occasionally cylindrical ("pebs

LOESCHE-MILLS

• Pressure shock resistance up to 8 bar (gauge). • Grinding pressure control for expansion of the mill control range from 20 to 100%; • Grinding table speed control with frequency converter. Loesche designs, plans and constructs everything from indivi-dual machines to turnkey dry-grinding installations for all solid fuels.
