Patent ID: 7819256

Claim:
Separator for separating heavy material components, particularly stones, ceramic material and glass, of an inhomogeneous flow of solid matter which comprises heavy and light material components, comprising a first conveying means for conveying the flow of solid matter; a second conveying means provided downstream of the first conveying means for conveying non-separated material components of the flow of solid matter; 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 adapted such that the light material components are transported from the first conveying means via 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, wherein the heavy material components bend the flexible means and overcome a restoring force of the flexible means to an extent that the heavy material components drop from a movable free end of the flexible means upstream of the second conveying means; and gas supply means for supplying gas such that the flexible means is supported against the bending caused by the weight of the light and heavy material components to an extent allowing the light material components to be transported from the first conveying means via the flexible means to the second conveying means.
