Abstract:
An improved enclosed belt conveyor system for transferring material with a minimum of dust and energy consumption. An alignment device having an external adjustment mechanism to adjust dynamically balanced spools, which are mounted on a shaft is terminated in the alignment devices. The belts for the conveyed material are in an enclosed structure while the bearings and the bearing adjustment mechanisms are external of the enclosed structure, which encloses the spools and the belts thereby limiting the debris or dust to which bearings are subjected. The balanced flared spools have closed and sealed ends, thereby totally eliminating air turbulence, within the structure. Turbulence will accentuate dust movement within the enclosure. This invention permits the alignment of each individual roller while maintaining the cones of the spools and bearings in a dust free environment as possible. The spool cone is not subjected to a fan-like effect at the ends of the spool creating air turbulence and depositing material in the cone.
