Crusher having a settable eccentric

摘要

The present invention relates to a crusher (1) having a crushing member (10) which is driven in an operatively connected manner via an eccentric element (11) such that material to be crushed that is introduced into the crusher (1) is comminutable by way of a crushing movement able to be brought about by the eccentric element (11). According to the invention, provision is made of at least one eccentric bushing (12) which is connected to the eccentric element (11) by a friction fit via an active surface (13), and wherein the eccentric bushing (12) has a pressure medium chamber (14) which has been introduced into the eccentric bushing (12) such that upon pressurization of the pressure medium chamber (14) the friction fit between the eccentric element (11) and the eccentric bushing (12) is variable.
