The latest reading of vibrating screen

AUTHOR: admin       DATE: 05 May 2012 08:18:00

In most traditional applications of vibration analysis, data is collected on rotating elements, such as motors, pumps, fans, compressors. This data shows the mechanical condition of the vibration screen. For example: bearing faults, gear faults, misalignment, coupling problems, etc. More advanced uses could include buildings and other structures, where data collected could detect certain design flaws and structural degradation.

A vibrating screen is a piece of equipment that separates different size material. Separation of material is accomplished by means of screening media, commonly referred to as decks, which act like a filter. The screen deck has certain size opening in it. The smaller material falls through the opening while the larger material remains on top of the screen deck. The entire screen can vibrate at up to 1000 cycles per minute and can have as many as three decks. The decks are arranged above each other, usually with the larger opening screen deck being on top and the lower screens having smaller opening respectively. As material is feed onto the top deck, the screen can vibrate at over 5 G's. The material falls through the openings and is separated. Each deck's overflow is usually directed into a chute and the material that falls completely through is sent to a chute.

These applications are certainly appropriate in the material handling industry. They are being implemented throughout the industry and established programs are starting to realize the many benefits of a vibration analysis program. However, there is a piece of equipment indigenous to this industry that escapes the more traditional analysts, the vibrating screen. They are normally passed over on the initial sight assessment due to their large and seemingly violent motion. However, the vibration analyzer is capable of providing a wealth of data that can help both maintenance and production get full utilization out of their vibrating screen machine.

The shaking screen is supported on all four corners by either steel springs or rubber 'donuts”, and it can either rest on the floor or be suspended by rods or chain. The motion of the mining screen is provided by an eccentric shaft. This shaft is inside a housing that serves as the mount for the bearing. Screens can have up to three shafts, each in their respective housing.
