Twin-band conveyor system for ore material, limestone and grain material e.g. sugar

摘要

The system comprises a lower horizontal conveyor part (1) which is arranged at a lower component and receives the fed material to be conveyed. A vertical conveyor part (2) conveys the material to an upper component which is provided with an upper horizontal conveyor part (3) and to which the conveyed material is discharged. The vertical conveyor part is connected with the lower and upper horizontal conveyor parts through respective bypass conveying parts (4,5). Support and surface protection bands (6,7) extend from the lower to the upper horizontal conveyor parts, via belt pulleys. The two conveyor bands (6,7) are provided with margin rollers (10) arranged over the entire length of the vertical conveyor part and at both sides of the bands. The bands are also provided with a pair of elongate plates (11) which are arranged over each band, along the path flow. The rollers are formed on each plate under a preset longitudinal spacing, so that the rollers are displaced on both plates.
