The function of a vibrating screen is to sort particulate material made up of a distribution of sizes into specific size groupings. Vibrating screens generally handle particles of size between 5 mm and 250 mm.
Jul 03, 2014· A vibrating screen is a piece of screening equipment used for dividing mixed materials of different size in few different levels of granularity. To do so, the vibrating screen uses one or more screen surfaces, made from heavy-duty materials. Also, it consists of a main frame, a motor, a coupler, an eccentric bock and few other parts.
This is the reason Kinergy Driven Vibrating Screens that are unidirectional are standardized in widths to 18 ft. and lengths as required. • Reduced Sound Levels: Kinergy Vibrating Screens operate smoothly and quietly, typically less than 60 dBA when in the no load or empty condition. Under load, 80 dBA …
vibrating screens. Vibrating screens generate sound levels ranging from 90 to 95 dB(A) during clean bituminous coal processing and 95 to 100 dB(A) during refuse and anthracite processing (Ungar et al., 1974). Because they are used to size, separate and dewater both coal and refuse (rock) of various sizes, screens may be located

Mar 01, 2013· Vibrating screens are a major noise problem in coal preparation plants because screens are used extensively in the plants, are usually located in high traffic areas, and can generate high sound levels 10. Coal preparation plants use horizontal vibrating screens more frequently because their smaller height allows for shorter floors and less overall building volume in a preparation plant.
How Vibratory Screens Work. Screening can very easily be viewed as the most important operation in the processing plant. If the screen is only operating at 75% efficiency, then 25% of the desired product is going somewhere else.
examine the noise radiated by horizontal vibrating screens below 1 kHz. vibrates, NIOSH performed sound level measurements near a group of eight horizontal vibrating screens used to process clean coal . These measurements indicated that the sound levels ranged from 94 to 98 dB(A) with the plant processing coal. With the
