The International Standard ISO 1940-1973 suggests a balancing grade equal to Gl6 (according to their classifi cation) with a limiting vibration velocity of 16 mm sec for rotating machinery having low operating speeds such as crushers. The German practice is to consider.For the two crushers which are expected to be identical. In addition, the crusher No.1 vibration values exceed the critical alarm thresholds recommended by the 10816 standard (see Group III of the standard shown in fig. 7), and the crusher continues to operate normally without any malfunction. Thus, it.
The ground-borne vibration and overpressure sound levels from the RRGP blasting operations are assessed per the MOE NPC-119 Guideline(MOE 1985) . There are two sets of criteria provided in NPC-119 cautionary limits and standard limits. The cautionary limits are used in the.Taking an example mentioned in ANSI HI 9.6.4 standard, assuming that a vibration intensity of 0.1 inches sec corresponds to 100 of nominal bearing lifetime, simply increasing the vibration level to 0.2 inches sec could reduce bearing lifetime to 60-70 of nominal bearing lifetime. Standards for pump vibration limits.
