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 are many different types of mills and many types of materials processed in them. Historically mills were powered by hand (, via a hand crank), working animal (, horse mill), wind or water ().

PERFORMANCE ENHANCMENT TOOLS FOR GRINDING MILLS 105 By locating microphones near the mill on fixed positions and applying appropriate algorithms online to the microphone signals, impacts on mill liners can be isolated from mill noise, then classified and counted to provide a quantitative measure of their occurrence. The observed
Monitoring and protection: sealing pressure and bearing temperature should be monitored in real time, control logic and interlocking can not be removed casually. When sealing pressure and bearing temperature are abnormal, it is necessary to stop grinding in time to prevent damage to the grinding roller bearing of the established mill.

This device monitors your grinding pressure at each of the grinding locations with a load cell. This information is then shown on a display on the side of the mill and/or in the control room. This data will help to calibrate your grinding pressure for proper fineness and thereby control capacity and mill DP. Another benefit is the ability to spread the load evenly across the main bearings.

During the design and production of our mills, we monitor every single detail – because often a small alteration is enough to make the grinding process even more efficient.
Improving knowledge of grinding technology and mill operations to operate, optimise and troubleshoot ball mill and vertical roller mill grinding installations. Ball mills and vertical roller mills are used for many grinding applications in cement production: raw meal grinding, coal and pet coke, and finish cement grinding.
REMOTE DIAGNOSTIC SERVICES FOR GEARLESS MILL DRIVES ABSTRACT Gearless mill drives (GMDs) are the workhorse in the mineral processing industries, more specifically when it comes to grinding crushed ore and cement (in various production stages) in semiautogenous (SAG) mills and large ball mills. They are renowned for their excellent reliability and
