Coal mill feeding device

Abstract

The application discloses a coal mill feeding device. The application comprises a feeding bin, an opening is formed in the side wall of the feeding bin; a sieve plate is arranged in the feeding bin in an inclined manner; a crushing component comprises a collecting bin connected with the opening of the feeding bin, a crushing roller is rotatably arranged in the collecting bin, and a guide plate is further arranged on the outer wall of the crushing roller; a crushing table is arranged below the crushing roller; a first power unit is arranged on one side of the collecting bin, and a return pipe is arranged between the collecting bin and the feeding bin; a transmission component is arranged between the crushing roller and the sieve plate; the sieve plate intercepts and conveys large-diameter coal into the collecting bin, the first power unit drives the crushing roller to rotate and guide the coal to move towards the return pipe, the gap between the crushing table and the crushing roller is gradually reduced, so that the coal is extruded between the crushing table and the crushing roller, until the coal is crushed, and the crushed coal is conveyed into the feeding bin through the return pipe, thereby reducing the blocking probability of the feeding bin and ensuring the quality and efficiency of the subsequent coal grinding process.
