ABSTRACT:
The present invention refers to a separator for separating heavy material components, particularly stones, ceramic material and glass, from a flow of solid material comprising heavy and light material components, comprising a first conveying means for conveying the flow of solid material, a second conveying means provided for conveying the non-separated material components of the flow of solid material downstream of the first conveying means, a flexible means arranged between the downstream end of the first conveying means and the upstream end of the second conveying means and which is formed such that the light material components are conveying from the first conveying means past the flexible means to the second conveying means and the heavy material components leave the flow of solid material in front of the upstream end of the second conveying means (5). The invention further refers to a method of separating heavy material components by means of a flexible means.
