摘要

Invention patent: b "method to fasten a plate of matrix of a mandu00ecbulas crusher, and a jaw mandu00ecbulas" d .A method for assembling a plate of matrix of jaws (9) of a jaw crusher, so as to release against a wall of the front end (10) of the crusher.By means of a clamping device (18) operated from the outside of a side wall (7) of the crusher.The matrix plate (9) is locked in place by means of a friction between the clamping device (18) and a counter surface (22) of the wall of the front end (10).And the friction between the clamping device (18) and the counter surface (23) of the plate matrix.The clamping device of the jaw crusher includes a piece of wedge (18) that has a first surface of the press to be adjusted against the counter surface (23) of the matrix plate (9) presAgainst the front end (10) of the crusher, and, in addition to a second surface of the press to be adjusted against the counter surface (22) of the wall of the front end.The piece of wedge (18) is mobile in the direction of both the counter surfaces (23, 22) as out of them by clamping means (19, 24, 20).
