Crushing ring of a crushing roller

摘要

The ring has a pin-shaped connector (14) for releasably fastening a crushing lid (6) at an associated projection (4). The connector is extended through a rear wall portion (8) of the lid and releasably held in the projection. The connector is extended at angle of 90 degrees formed between a longitudinal axis of the connector and a rotation direction of the ring. The angle is formed by a rear wall surface of the projection. The angle is less than 90 degrees with reference to a portion of the rear wall surface lying between the connection and a connecting head portion (9).
