Embodiment Construction

[0044] In the following description, like reference numerals denote like elements. It should be noted that the drawings are not in all instances drawn to scale and that they are mainly for the purpose of illustrating embodiments of the invention.

[0045] figure 1A jaw crusher 100 is schematically shown, which includes: a fixed jaw 101 as the front part of the jaw crusher; Supported by eccentric disc 103 . The rear part 105 of the frame of the jaw crusher is fastened between these side plates. The pendulum is supported below the eccentric disc by the bracket 106 from the rear of the frame. The pendulum portion is moved back and forth towards a fixed jaw 101 located at the front end of the jaw crusher and fastened to a side plate 104 of the frame.

[0046] The upper wear part 107 and the lower wear part 107' are fastened to the fixed jaw, and correspondingly the upper wear part 108 and the lower wear part 108' are fastened to the pendulum. The locking device 10 is used to ...

Abstract

In the method for adjusting the tightness of a wear part (107, 107', 108, 108') fastened to a fixed jaw (101 ) and / or a moving jaw (102) of a jaw crusher (100) with a tightening device (10) that comprises a screw (11) fastened at its first end (11 ') in connection with a wear part located on a first side of the jaw; and a tightening member (17) fastened to a second end (11'') of the screw on a second side of the jaw; and a spring (15) arranged between the jaw and the tightening member; the spring is compressed or decompressed with the tightening member; the spring (15) is influenced by at least two moving screws (18) supported by a frame of the tightening member (17); and the length of the spring is changed by rotating said at least two moving screws. Tightening member (17). Tightening device (10). Jaw crusher (100). Processing plant of mineral material (200).

Description

technical field [0001] The invention relates to the locking of wear parts fastened to jaw crushers. Background technique [0002] Mineral material, such as rock, for crushing may be obtained from the ground by blasting or excavation. The rock can also be natural stone and gravel, or construction waste. Crushing can be performed using non-stationary crushers and stationary crushing equipment. The material to be crushed is fed by means of an excavator or wheel loader into the hopper of the crusher or crushing plant, from which the material to be crushed can fall into the throat of the crusher, or by a feeder Transfer rock material to crusher. The mineral material to be crushed can also be a recyclable material such as concrete, brick or asphalt. [0003] Jaw crushers are suitable, for example, for rough crushing in quarries or for crushing construction materials. According to the working principle of the jaw crusher, crushing is carried out in jaws called fixed jaw and mo...
