Vibration monitoring has become essential for plant and equipment predictive maintenance in mining and quarrying Not only a valuable tool for preventing unscheduled downtime it can also extend machine operating life beyond recommended maintenance intervals and can help to avoid catastrophic and dangerous failure
Oct 16 2018 · Equipment that is showing excessive vibrations will most likely not achieve the expected lifespan and can be the source of unscheduled downtime or dangerous situations Therefore it is important to find the root cause of vibrations by measuring and analysing the vibration signals Common causes of vibrations are discussed below
Ground vibration monitoring Reduce the risk of harming structures and sensitive areas with our Vibration Monitoring either attended or unattended the portable system provides indepth understanding of construction and mining vibration levels to make better informed decisions
Jan 08 2015 · Noise may be generated by the impact from drill bits and mechanical vibration from drill casings as well as impulse noise from exhaust and ancillary equipment such as fans and blowers for mine ventilation There seems to be no limit to the array of noisecreating equipment at play in the mining industry To complicate matters further the
Mar 06 2020 · The mining industry has a reputation for being a risky business with health risks that are varied and often quite serious and it is important for miners to protect themselves accordingly Nevertheless mining doesn’t have to be unsafe With the introduction of strict safety legislation and protocol as well as advances in safety equipment the industry has seen its fatality rate drop over
Vibration measurement has come of age in the last 20 years While the practice of continuous online monitoring of critical machines in the oil gas and petrochemical industries has been commonplace for several decades it is only recently that companies who had been using intermittent data collection techniques are now embracing continuous monitoring
The mining industry is a heavy industry where condition monitoring equipment must survive mechanical and environmental forces The SPM product range includes portable instruments online systems and accessories specifically suited for shock pulse monitoring of rotating machinery and vibration monitoring equipment for detecting misalignment
The other dimension of the blast vibrationlift acceleration shear and settlement cause different types of damages Fig 134d to the buildings Noise Monitoring The surface mines generate noise from blasting excavation and transport while the major noise sources from underground mines are the ventilation fan haulage conveyor
Sep 21 2020 · A vibration problem associated with journal bearings is the possibility of hydraulic instability of the rotating shaft inside the bearing This vibration is caused by “oil whirl” or “oil whip” This is caused when a wedge of lubricant moves the shaft in an eccentric motion as the shaft rotates which if severe enough will cause a vibration
Impact shock and vibration caused by heavy equipment also occurs in mining and when producing pulp and paper Here too Fabreeka pads washers and bushings have long been reliable solutions to reduce impact shock and vibration in a wide variety of operations

A conveyor system that comes out of alignment can easily damage equipment at transfer points or cause fugitive material to spill off the belt Material can stick to belts and be carried back into the equipment requiring a shutdown for cleanup Fugitive dust can become airborne causing
Maintaining earthmoving machinery is something that must be done to prevent major problems down the road The last thing you want on a mining site is nonworking equipment Improper maintenance will shorten the lifespan of machinery cause it to breakdown frequently require costly repairs and slow down your operations
Dec 15 2002 · Equipment reliability is not the software equipment reliability is the intelligent use of knowledge and information to reduce mean time between failure MTBF using tools such as root cause analysis If data mining is cost effective in promoting reliability then it is a good investment If not then don’t waste your money Fig 4
