Concrete separating device

摘要

The present invention relates to a separating device for crushing concrete. The separating device comprises at least two crusher members which, optionally in co-action with bounding elements situated adjacently of the at least two crusher members, define at their upper outer ends an inlet opening for concrete to be crushed and at their lower outer ends an outlet opening for crushed concrete or at least concrete fractions. The separating device further comprises a drive device adapted to move repetitively at least a part of one of the two crusher members in the direction away from and toward the other crusher member. Outlet restriction means are provided under the outlet opening to limit an outflow of crushed concrete and/or concrete fractions. The invention further relates to a method for crushing and separating a composite material, in particular concrete, into original components.

主权项

1. A separating device for crushing and at least partially separating concrete into original components, comprising at least two at least substantially plate-like crusher members, which crusher members comprise upper outer ends which define an inlet opening for concrete to be crushed and at their lower outer ends an outlet opening for crushed concrete or at least concrete fractions, and a drive device operatively coupled to at least one of said crusher members, which drive device is adapted to move repetitively at least a part of one of the two crusher members in directions away from and toward the other crusher member, wherein an outlet restriction is provided under the outlet opening to limit an outflow of crushed concrete and/or concrete fractions, and wherein a push-back is provided which drives matter situated between the crusher members in an upstream direction, at least when the crusher members are not moving away from each other, said push-back being operatively coupled to at least one of the crusher members.
