Description

Technical Field

[0001] The utility model relates to the technical field of roller presses, and more specifically, to a feeding device for a roller press. Background Art

[0002] The roller press is designed according to the principle of material bed grinding and consists of two extrusion rollers rotating synchronously in opposite directions, one is a fixed roller and the other is a movable roller. During processing, materials are introduced into the pressure-stabilizing feed bin for processing. Two oblique feed plates are installed in the pressure-stabilizing feed bin of the roller press for material dumping. However, since the oblique feed plates are mostly fixedly installed, the feed amount and feed speed are difficult to control and adjust, and are prone to blockage, which in turn affects the processing efficiency of the roller press. In addition, most of the feeding devices of the roller press are open. During the operation of the roller press, the pressure applied to the material can easily cause the material to fly out, which is relatively dangerous. Utility Model Content
