Title:
CRUSHER
Document Type and Number:
Japanese Patent JP3671086
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To crush in a good condition even when dimensional errors, which are made in the production, exist on the crushing surfaces of upper and lower mortars in a crusher for crushing a material by cone-shaped crushing surfaces of the upper and lower mortars.
SOLUTION: An upper mortar 12 is engaged with a fixed lower mortar 9 rotatably by cone shaped crushing surfaces 9a, 12a. A material discharge opening 13 is formed in the upper mortar 12 to supply a material to be crushed to the crushing surfaces 9a, 12a. A driving shaft 26 is installed to penetrate the middle parts of the nor-tars 9, 12. The upper mortar 9 can be slanted slightly to the driving shaft 26 and is engaged to be rotated by the driving shaft 26. Mounting nuts 18 for pressing the upper mortar 9 to the lower mortar 12 are attached to the end of the driving shaft 26.
