Embodiment Construction

[0032] In the following description, the same reference numerals denote the same components. It should be appreciated that the figures shown are not to scale as a whole and that they serve only to illustrate embodiments of the invention.

[0033] exist figure 1 In the figure, a mineral material processing equipment including a crushing device 200 of a jaw crusher 100 is shown. In the crushing device 200 there is a feeder 103 for feeding material to the jaw crusher 100 and a belt conveyor 106 for further conveying the crushed material from the crushing device.

[0034] figure 1 The belt conveyor 106 shown in includes a belt 107 arranged to travel around at least one drum 108 . The crushing device 200 also includes a power source and a control center 105 . The power source may for example be a diesel or an electric motor, which provides the energy used by the processing unit and hydraulic lines.

[0035] The feeder 103 , crusher 100 , power source 105 and conveyor 106 are att...

Abstract

A pitman of a jaw crusher (1; 1') comprises an upper part (2), which comprises an upper supporting point (3) for supporting the pitman in the body of the jaw crusher, and a lower part (4) comprising a lower supporting point (5) for supporting the pitman in the body of the jaw crusher through a toggle plate. The lower part (4) of the pitman (1; 1') comprises sidewalls (13) and honeycomb structure open to the crushing direction, the structure comprises one or more cross-sectional supports (15) reaching from the first sidewall of the pitman to the second sidewalk. A jaw crusher (100), a crushing plant (200) and a method for increasing crushing capacity of mineral material are also provided.

Description

technical field [0001] The invention relates to a connecting rod of a jaw crusher, a jaw crusher, a crushing device and a crushing method, which are suitable for crushing mineral materials. Background technique [0002] The function of the jaw crusher is based on the force pressing stone, the jaw moving relative to the eccentric shaft moves back and forth about the fixed jaw. The movable jaw, i.e. the connecting rod of the jaw crusher, has been produced in various ways. The cast connecting rod is closed, ie closed in its cross-sectional profile. In patent publication EP1049539B1 a jaw crusher with connecting rods of closed cross-sectional profile is proposed. [0003] Manufacturing a connecting rod from a closed contour requires several different work stages. When casting, a core is required in order to produce a closed profile part. The movement of the core during casting causes the webs to have different wall thicknesses, so that the wall thickness of the casting has t...
