Mineral sizers is a highly efficient material crushing and grading equipment for coal, mining, metallurgy, power and other industries. Mineral sizers produced by our company is a kind of equipment with adjustable center distance to adjust the discharge particle size, which can be adjusted according to the needs of different customers. The following is our organization about how to adjust the center distance of mineral sizers and its advantages. Mineral sizers with adjustable center distance are characterized in that they comprise a frame, a fixed tooth roller assembly, a base plate, a moving tooth roller assembly and a connecting plate; the fixed tooth roller assembly is fixed at one end of the frame, and the tooth roller of the fixed tooth roller assembly extends in the first direction; the bottom plate is connected to the other end of the frame, and the bottom plate slides in the direction near or away from the fixed tooth roller assembly in the second direction, and the second direction is perpendicular to the first direction; the moving tooth roller assembly is fixed on the bottom plate, and the tooth roller of the moving tooth roller assembly is parallel to the tooth roller of the fixed tooth roller assembly; the connecting plate is arranged between the fixed tooth roller assembly and the moving tooth roller assembly, and one end of the connecting plate is fixed connected with the fixed tooth roller assembly; the other end of the connecting plate and one of the moving tooth roller assembly is provided with a long strip hole, the other end of the connecting plate and the other one of the moving tooth roller assembly is provided with a bolt hole, the long strip hole extends along the second direction, and the fixing bolt is installed between the long strip hole and the bolt hole. The mineral sizers with adjustable center distance are characterized in that they also include a limiting screw and a baffle; the limiting screw is fixedly connected to the bottom plate and/or the moving tooth roller assembly away from the fixed tooth roller assembly, and the limiting screw extends along the second direction; the baffle is located on one side of the limiting screw away from the fixed tooth roller assembly, the baffle is fixed connected to the frame, the baffle is provided with a through hole for the limiting screw to pass through, and the limiting screw is installed on both sides of the baffle corresponding to the locking nut.

The mineral sizers with adjustable center distance also include anchor bolts; the head end of the anchor bolt is fixed on the frame and the threaded end of the anchor bolt is arranged in the opening hole preset on the bottom plate, the opening hole extends along the second direction, and the anchor bolt is installed with fixing nuts on both sides of the corresponding bottom plate. The plate is glibly connected to the frame through a linear guide rail assembly, which comprises a guide rail and a slide rail; the guide rail is fixed on the frame and extends along the second direction; the slide rail is sliding connected to the guide rail, the slide rail slides along the extension direction of the guide rail, and the slide rail is fixed connected with the bottom plate.
