Document Type and Number:
Japanese Patent JP4283765
Kind Code:
B2
Abstract:
A wear part ( 5 ) for detachable mounting on a supporting part in an impact-type multi-action crusher is at least partly manufactured by hot isostatic pressing. The wear part ( 5 ) has a body ( 19 ) for mounting of the wear part ( 5 ) on the supporting part and a crushing layer ( 20 ) which is attached to the body ( 19 ) and which is adapted to be brought, during operation of the crusher, into repeated contact with a raw material that is to be crushed. The body ( 19 ) is made of a substance which is easy to machine to narrow tolerances, and the crushing layer ( 20 ) is made of a material ( 27, 28 ) of high abrasive resistance. In a method of manufacturing the above wear part ( 5 ), the following steps are carried out: introducing at least one powder material ( 27, 28 ) into a capsule, degassing and sealing the capsule, subjecting the material ( 27, 28 ) in the capsule to hot isostatic pressing to form a crushing layer ( 20 ), and then after treatment of the wear part ( 5 ).
