Flow fracturing device e.g. for cutting up lumpy or granular goods, has chain conveyor transporting stones with breaker provided which breaks stones in breaking area and which are then moved over rasps

摘要

The crusher mechanism has a chain conveyor transporting stones. A breaker is provided which breaks the stones in a breaking area and which are then moved over rasps (27). The rasps are arranged between lateral chains (28) and bags (29) of defined size. The bags store the stones (11b) of particular grain size, which is smaller than the size of the bags. In a moving direction (15) and before the breaking area (16) a drag chain (21) is provided for conveyor. Ends of the chain (22, 23) are attached to attachment points (24, 25) so the stones travel centrally between the chain ends.
