  • Patent number: 7686241
    Abstract: In a jaw crusher, cheek plates are mounted on side wall plates of a crusher frame by mounting bolts, and the mounting bolt adjacent to the outlet of the jaw crusher can be covered with the swing jaw by adjustment of an outlet gap-adjusting link mechanism. When the jaw crusher is in operation, the mounting bolt is covered by the swing jaw to avoid contact with raw materials, so that abrasion of and damages to the mounting bolt can be prevented. Thus, a longer lifetime of the jaw crusher can be promoted. Besides, since abrasion of and damages to the mounting bolt can be prevented, a mounting structure of the cheek plate can be stronger.

  • Publication number: 20040129815
    Abstract: There is provided a jaw crusher capable of providing a toggle plate holder mechanism without increasing the overall height thereof. A tension link mechanism (70) as the toggle plate holder mechanism includes a link having a tension link (71), tension lever (72), tension rod (73), and tension spring (74). Therefore, the layout angle of the tension link (71) and tension rod (73) can be changed freely by the tension lever (72). The freedom of layout in the height direction can thus be improved. As a result, without increasing the overall height, the toggle plate holder mechanism can be provided for the jaw crusher 30 having a reaction force receiver link mechanism 60 of an up-thrust type.
