Background

The double-roll crusher (also known as double-roll crusher) has the advantages of simple structure, reliable work, low price, uniform product granularity and the like, and is a common ore processing machine. Due to different ore sizes, the crushing requirements are different. The distance between two crushing rollers of the existing double-roller crusher can be adjusted generally so as to adapt to diversified production scenes.

The adjustment mode is that one of the rollers is arranged on a sliding plate, and the sliding plate is connected with the frame in a sliding way. Because the roller crusher vibrates greatly in the working process, the sliding plate also vibrates easily along with the roller crusher, the roller crusher is damaged, and the service life of the roller crusher is shortened. Therefore, people set a limiting mechanism on the frame to limit the vibration of the sliding plate. The existing limiting mechanism is a structure formed by adding two simple vertical plates and a transverse plate at the top, and one or more bolts are vertically installed at the contact position of the vertical plates and the transverse plate to play a role in fastening. The vibration of the sliding plate can be limited in a short time by the limiting mode, but after the time is prolonged, the bolt is loosened due to the vertical vibration of the sliding plate, and therefore the limiting effect can not be achieved any more. And diaphragm and riser all with slide direct impact, cause the deformation of diaphragm and riser easily, finally influence the normal slip of slide.
