The obtained results of the measurement of the sound intensity of mining machines and devices point to repeatedly exceeding the permissible hygienic standards of Polish and European noise emission.
A common cause of vibration is when the machine shafts that are out of line. Misalignment is a root cause of many machine breakdowns, bearing failures, and damaged seals, shafts and couplings. In fact, it is widely believed that over 50% of machine failures are due to misalignment.
In this paper, to forecast the effect of blast- induced ground vibrations, dimensional analysis (DA) is proposed to predict peak particle velocity (PPV). In conventional …
The feature is high axial vibration; It has 180° phase difference between the coupling sides; It typically has high axial vibration at 1X and 2X speeds; Usually, 1X, 2X or 3X RPM frequencies do not dominate; Symptoms can indicate coupling failure.
Using vibration monitoring in mining applications is proven to maximize operational uptime and minimize maintenance costs. Detecting and preventing unexpected component problems is a priority. Vibration monitoring helps to establish machine baselines, and can continuously trend key components for 24/7 observation.
According to the practice, the causes of high bearing temperature rise may be poor assembly of rolling bearing, too small radial clearance of rolling bearing, too much or too little lubricating grease, unqualified lubricating materials, bearing dirt, wear, seal failure, etc., or too large difference between motor shaft and exciter shaft, As a ...
There are many factors affecting the work of the shaking table, among which the main stroke, the number of strokes, the concentration of ore feeding, the amount of ore feeding, the flushing water for the ore body, the lateral slope of the bed surface, and the nature of the ore feeding. (1) Stroke and stroke […]
Vibrating Screen Machine Working Principle Vibrating screen uses electric exciter as a vibrating source, the material will be thrown around the screen, at the same time doing forward sports, in order to achieve the screening purpose. Material from the feeder evenly enters into the machine's feeding inlet, with multilayer sieves to produce various …
They should do this by using a high-tech machine that they put the tire onto and then spin the tire at high speed. The machine monitors the way the tire is rotating, and it identifies where the mechanic can mount some small weights to make the tire roll more smoothly. An imbalance of just a fraction of an ounce can cause vibration.
1. Introduction. Whole-body vibration (WBV) has been identified as one of the dominant occupational hazards in the mining industry (Chaudhary et al., 2015a).In recent years, the number of injuries associated with mining vehicles has increased (Kia et al., 2020).However, it can be a significant problem in other industries such as …
Whilst operating at low flow, a machine is under much greater duress than at most other operating flows. To understand why operating at extreme low flows can cause pump problems, it is instructive to analyse the nature of the flow through the machine. Using computational fluid dynamics, Hydro Australia has been able to model this flow …
From European data it is clear that the risks for excessive WBV vibration exposure is high in mining and construction. As summarised in "Bad Vibrations" [McPhee et al, 2009] …
The mobile vibration sand screening and conveying machine is a multi-functional equipment with a complex structure.It consists of multiple components such as a vibrating screening part, a conveying part, a support structure, a control system, and moving parts to screen granular materials such as sand and gravel. It is suitable for sand and gravel …
The scope of the research included measurements on a broad spectrum of tools, machines and vehicles used in the South African mining industry. Both hand-arm vibration, where the majority of the vibration enter the body through the hands, and whole body vibration, where the whole body is exposed to vibration through contact by the …
See below for an explanation of key issues often encountered in mining applications and how vibration monitoring can help you reduce risk and keep your plant running smoothly.
˙e detonation of the rock mass during the blasting process causes ground vibration. An explosive charge is inserted into the blast hole in order to explode and shatter rocks.
Vibration can help to find the location of the fault. Vibration can help to find the cause of the fault. Vibration measurement is non-invasive. Most faults show increased vibrations in an early stage of the deterioration sequence. Vibration can be measured instantaneously. Vibration can indicate the severity and deterioration rate of a fault. 4.
mining industry. Both hand-arm vibration, where the majority of the vibration enter the body through the hands, and whole body vibration, where the whole body is exposed to vibration through contact by the buttocks or feet, were investigated and measured. More than 700 sets of vibration data measured on 70 machines
The investigation compares the conventional, advanced machine, deep, and hybrid learning models to introduce an optimum computational model to assess the ground vibrations during blasting in ...
A field study was conducted to evaluate the vibration risks to the operators using mining machines in open pit mines. Vibration levels and whole-body vibration (WBV) measurements using various ...
In the mining industry, vibration enters an operator's body either through hand-held machines (handarm vibration (HAV)) or through the machine's seat surface or seat floor (whole-body vibration ...
The study has diagnosed the first cases of HAVS in the South African mining industry, and possible explanations for this may include a survivor population, and lack of vascular symptom reporting due to warm-ambient temperatures. BACKGROUND Hand-arm vibration syndrome (HAVS) is associated with the use of hand-held vibrating …
The development of international standards for vibration-related disorders caused by whole-body vibration (WBV) and hand-arm vibration (HAV) is reported and …
Resonance may cause violent swaying motions and even catastrophic failure in poorly designed structures including bridges, buildings, trains, and airplanes. Needless to say, it can be harmful to humans too. In structures, a high level of vibration can cause cracks, loose bolts, heavy noise or even failure.
