It is Necessary to Examine Vibrating Screen Before Operation

AUTHOR: admin DATE: 12 Jan 2013 02:15:51

Vibrating screen has been widely used in mine, construction, transportation, energy and chemical industries. To prolong the working life of the bearing, proper lubrication , protection plans, as well as bearing state detection work should be taken into account. Inappropriate vibratory screen bearing clearance can cause a metallic sound. Sharp squeaking noise may be caused due to improper lubrication. Dent bearing peripheral track will cause vibration, resulting in a smooth and crisp sound, if the percussion scars caused due to the installation, will also produce noise.

The mining industry is one of the biggest users of vibrating screen technology. Taking ore andminerals from the ground results in many impurities, so these organizations load goods into a screen until dirt and non-valuable rocks are shaken from material such as coal, iron and ore. Screens also are utilized in manufacturing, especially when metal items, such as ionized bolts and screws that need to be submerged in a bath, need to be dried. Here, full containers of liquid and metal can be poured through the screen and separated with the vibrations to ensure that they dry completely. Disparate industries such as archaeology, metallurgy and construction also utilize vibrating screen technology to get their jobs done.

Listening is one of the methods to check whether the vibrating screen is abnormal. We can use the hearing to recognize irregular operation of vibrating screen, such as through electronic auscultation to detect a particular part of the normal noise, which is an experienced operator often to use. If the bearing is in good condition, vibrating screen will be issued a low hum sound, if issued a sharp hissing sound, squeaky sound, and other irregular sounds, usually shaking screen bearings are in adverse operating conditions.

If it has situation of tremendous noise, we must replace the bearing immediately. Therefore, a better way such as the use of electronic situation to test equipment, pre-diagnosis of the functioning of the vibratory screen bearings. Compared to the old method, the use of advanced instruments is a more accurate estimate of the vibrating screen bearings situation.

The vibrating screen is a kind of sieving equipment of international advanced level, developed by our company on the basis of carrying on the advantages of traditional screens and absorbing the outstanding technology from abroad
