Alternate Conveyor Design for Mine Machinery.
NTIS: PB/265-151 Available for Reference At Bureau Libraries :57 pages
This report presents results of a program to develop a new conveyor system, adaptable to existing miners or loaders, which reduces the noise to 90 dba without reducing machine performance. The trial conveyor design consists of a main conveyor and a swinging tail conveyor. The main conveyor incorporates a rubber-covered return guide roller, rubber mounting of pillow blocks, rubber cover of the return bed, and a rubber belt running between the flight chain and the conveyor bed plate. Testing took place in a surface coal pit and underground at the Peabody Spur Mines in Boonville, Indiana. Noise levels as low as 90 dba were observed on the surface and 93 to 94 dba underground. Recommendations for further work are also presented.
