Abstract
A scraper blade for a conveyor belt cleaner is provided. The scraper blade being adapted, when appropriately tensioned against a conveyor belt, to maintain a plurality of predetermined cleaning angles, relative to the conveyor belt, as the scraper blade is progressively worn down through contact with the conveyor belt, the scraper blade having a first blade section and a second blade section. The first blade section is proximate a distal end of the scraper blade, the first blade section being configured to maintain a first predetermined cleaning angle relative to the conveyor belt. The second blade section substantially adjacent the first blade section, the second blade section being configured to maintain a second predetermined cleaning angle, relative to the conveyor belt, after the first blade section is worn away through contact with the conveyor belt. The second predetermined cleaning angle is different than the first predetermined cleaning angle. The first blade section and the second blade section each define a profile which approximately corresponds to a volute of a circle. Processes and computer implemented processes for designing outer profiles and inner profiles of primary scraper blades and secondary scraper blades are also provided.
