A complete assessment of exposure to vibration requires the measurement of vibration acceleration in meters per second squared (m/s 2). Vibration exposure direction is also important and is measured in defined directions. Vibration frequencies and duration of exposure are also determined.
and especially since motors have been used to power them, problems of vibration reduction and isolation have engaged engineers. Gradually, as vibration isolation and reduction tech niques have become an integral part of machine design, the need for accurate measurement and analysis of me chanical vibration has grown. This need was largely sa

f 0 = Maximum variable frequency drive output frequency If 2L min < L max then any value between these limits can be used. If 2L min > L max then the variable frequency drive cannot operate with this length of cable and a higher rated variable frequency drive must be used. Consideration must be given to the high frequency losses in the chokes.

Machinery Vibration Limits and Dynamic Structural Response Vibration monitoring of rotating machinery has developed over the years to the point where it is an accepted maintenance tool. Much effort has been applied towards developing guidelines regarding acceptable absolute levels of vibration. Discussions of some of these standards and
• cement industry: Nghi Son, Vietnam, 1998,Guangzhou, China, 2005. Loesche developed the 4roller coal grinding mill with four tried and tested modules for throughputs over 150 t/h. The development was first realised in 1970 for grinding mills in the cement industry. This number of rollers also enables operation with only one pair
FCB has just developed a new mill, HOROMILL ®, for grinding cement, raw meal and new grinding process is designed for finish grinding and also for pregrinding. The energy saving is similar to the roll press, roughly 30% to 50% better than the ball mill, but with a moderate circulating load and grinding pressure.

Vibration Measurement Systems and Guidelines for Centrifugal Fans A Field Perspective Robert A. Shannon, PE Design Engineering Manager Howden Buffalo Inc. ABSTRACT This paper presents an overview and discussion on vibration measurement systems, transducer types, advantages and disadvantages, and usage guidelines for centrifugal fan applications.
A wellplanned preventive maintenance program is the key to dependable, longlife operation of motors and modern plant operations, unscheduled stoppage of production or long repair shutdowns are intolerable. The high cost of the resultant downtime eats deeply into profits. Although management probably realizes the value of a good preventive maintenance (PM)

More stringent specifications regarding motor vibration call for maximum velocity levels of in./sec on the housing and mils of displacement vibration on the shaft. The limits apply to a motor mounted on a seismic mass, and uncoupled or coupled to a piece of equipment in a way that eliminates any vibration in the driven equipment.
