Stone separator with air separator

摘要

A device for processing a material mixture, with a first conveyor belt which is connected to a chamber, has at least one pressure blower provided in the internal space of the chamber for generating an airflow aimed from below at the material mixture falling into the chamber. At least two collectors are arranged offset along the chamber floor at different distances to the entry point of the material mixture which faces the chamber. These collectors are delimited from one another in terms of surface area by at least one separating crest, which is movably arranged on the chamber floor and extends from the chamber floor in the direction of the chamber upper side. A first material group, such as stones and/or inert materials and/or heavy parts, with the lowest fluid resistance of all material groups of the material mixture, is separable at least to some extent from the material flow in a first separation region, in which a fluid flow and a material mixture flow through the device. In a second separation region with a settling zone and a first negative pressure region, a second material group is separable, at least to some extent.

1. A device for separating stones, inert materials, and/or heavy parts from a material mixture, comprising:
a first conveyor belt, which is connected to a chamber, at least one pressure blower provided in an internal space of the chamber for generating an airflow aimed from below at the material mixture falling into the chamber, and at least two collecting means arranged offset along a chamber floor at different distances to an entry point of the material mixture which faces the chamber, said collecting means delimited from one another in terms of surface area by at least one separating crest which is movably arranged on the chamber floor and extends from the chamber floor in the direction of a chamber upper side, wherein a first material group with a lowest fluid resistance of all material groups of the material mixture is separable at least to some extent from a material flow in a first separation region, wherein a fluid flow and said material mixture, which has at least three different material groups separable by way of the device, flow as a material stream through the device, and wherein, in a second separation region with a settling zone and a first negative pressure region, a second material group is separable from a main direction of the material flow and the settling zone at least to some extent by way of the first negative pressure region in a horizontally lateral direction.
