Problems solved by technology

In some cases, elongated objects such as reinforcing rods may unfortunately have their ends trapped in the exposed openings of the clamping rods or through-holes on the surface of the jaw template if the two-part jaw template and / or Or if the jaw formwork used as an extension is used facing and exposed to the crushing cavity, the reinforcing bar will end up in an "upright" position inside the crusher during its operation, causing serious crushing problems

Embodiment Construction

[0037] exist Figures 1 to 2 A jaw crusher 1 is shown in . The jaw crusher comprises jaws 2, 2' and a movable jaw 3 and a fixed jaw 3', each jaw being provided with at least one jaw 2, 2'. If the jaw is divided into more than one part like an elongated or widened jaw part or jaw part, the jaw is held firmly against each A jaw 3, 3'. Such an elongated jaw part 10 does not necessarily have the function of a clamping rod, but can of course have this function or be used in combination with at least one clamping rod 10 . Such an elongated jaw plate 10 may have the same height as the adjacent jaw plate or another height, eg a smaller height measured in the vertical or feed direction of the crusher. Each jaw 3, 3' or jaw plate 2, 2' comprises an upper surface 4 inclined to define a wedge-shaped surface on which the jaw member / clamping rod 10 is wedged to securely clamp the jaw in the appropriate location in the crusher (see figure 1 , 2 and 9). Each jaw 3, 3' or jaw plate 2, 2...

Abstract

The invention concerns a jaw plate part (10) for securing jaw plates (2, 2') to a jaw crusher (1) comprising at least one such jaw plate part for securing a jaw plate to a jaw (3, 3') of the jaw crusher, the jaw plate part may work as a wedge being detachable from the jaw crusher. The invention also concerns a jaw plate part unit comprising at least one such jaw plate part and fastening means (50). Moreover, the invention also concerns a jaw crusher comprising at least one such jaw plate part unit for securing jaw plates of the jaw crusher.

Description

technical field [0001] The present invention relates to a jaw crusher for crushing that can be suitably used in the construction and mining industries. Background technique [0002] When crushing hard materials such as stone or ore blocks, different types of crushers are used. One example of a type of crusher is a jaw crusher, where a typical jaw crusher includes a fixed jaw and a movable jaw spaced apart to define a crushing chamber therebetween. Material to be crushed is fed into the crushing chamber and crushed by the face of each jaw as the movable jaws repeatedly move towards and away from the fixed jaws. [0003] The jaws of the crusher are subjected to enormous forces and wear as well as vibrations during the crushing process. The jaw is therefore equipped with a formwork for protection against wear on its face, i.e. an outer formwork called the jaw plate, which acts as a wear protector and a crushing surface in contact with the material to be crushed, and an interm...
