WASTE GLASS LABEL REMOVER

摘要

The detection methods for labels coatings or contaminants on waste or broken glass, arranged before a recycling process often give false readings on determining the true nature of the materials present, hence an at least partial removal of said contaminants is necessary. An intensive abrasion of the waste glass or broken glass introduced into the unit with continuously applied shear and compression forces between blades (6) and a housing (10) is generated by the provision of a dry-washing unit with just one rotating driven shaft (12), to which the blades (6) are fixed with a fixed minimum separation (16) from the inner wall of the housing (10). The required abrasion is achieved by compression of the material flow, and the friction of the shards against each other thus generated and also by the transport process within the machine. By means of a suitable interaction of the blades (6) and the housing (10), a thorough and complete abrasion of the labels and contaminants sticking to the broken glass can be achieved which renders a manual material selection unnecessary.
