1 Introduction. Exposures to WBV are evident in the industrial world, in particular for earthmoving equipment including offroad vehicles. WBV comprises mechanical vibration or shock transmitted to the body as a whole (Griffin, 1990).When WBV is transmitted to the human body at the natural frequency of the body as a whole or of its individual parts a condition known as resonance will result.
The Cleveland Vibrator Company offers electric and pneumatic industrial vibrators and vibratory solutions for industrial jobs in mining, agriculture and food, pharmaceutical and medical device, powders, foundry,, stone, aggregate and concrete, plastics, recycling and other manufacturing.

Causes of Vibration. identifying of the root cause of any problem helps us to tackle the same with great ease. This applies to vibration also. Most of the machines we use in our day to day life like the Mixer, Washing Machine, Vacuum Cleaner, etc. tend to indicate if something is wrong in them by means of vibration and noise (a major byproduct caused by vibration).
The Challenges of Monitoring Mobile Mining Equipment. ... 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 ...
Condition Monitoring for Conveyors Page 4 CONDITION MONITORING for CONVEYORS A TOOL for INCREASED PRODUCTIVITY SYNOPSIS A stoppage in the conveyor transport system means no production in most mining applications. Whether the stoppage is due to a minor problem or a major problem, the effect is the same.
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.
distance from the blasthole, the explosive energy released decreases to a level, which causes no further shattering or displacement, and continues to travel through the rock as an elastic ground vibration. The ground vibration radiates out from the hole with decreasing intensity and reduces to below levels of perception with distance.
