Investigation in characteristics of belt conveyors and their idler rollers for coal-fired power plants

Исследования характеристик ленточных конвейеров и их несущих роликов для угольных электростанций

  • Belt conveyors are highly efficient systems used in mining and other industries to transport bulk materials, mainly brown coal and overburden, over distances ranging from short distances to several kilometres. For technical reasons, their operation is associated with noise emissions. During inspections and maintenance this can lead to increased noise exposure of employees. In the vicinity of residential buildings or in areas needing protection, exceeding the emission limits can lead to a temporary restriction of the operation of these high performance installations. Measures are required to reduce the noise impact primarily at the source or in the immediate vicinity. The acoustic and mechanical parameters are investigated on a test bench at the Technical University of Brandenburg (BTU) Cottbus-Senftenberg as part of the drive assembly tests in cooperation with LEAG. The stages of these tests are: Run-up test. In this test the supporting roller is accelerated under test load to a circumferential speed of 10 m/s and the sound pressureBelt conveyors are highly efficient systems used in mining and other industries to transport bulk materials, mainly brown coal and overburden, over distances ranging from short distances to several kilometres.

The stages of these tests are: Run-up test. In this test the supporting roller is accelerated under test load to a circumferential speed of 10 m/s and the sound pressure level is recorded. This makes it possible to calculate the sound emission as a function of the peripheral speed; Recording the geometry of the idler gear. An accurate description of the geometry of the idler housing allows conclusions to be drawn about the possible causes of excitation. The defined characteristics serve to quantify the acoustic effect of the driven rollers and derive specifications for use in belt conveyor systems. Based on the special requirements to the planned belt conveyor system, an adapted selection of low-noise idler rollers can be made at an early stage on the basis of specified parameters and confirmed test results.show moreshow less
