Horizontal fine grinding machine

Abstract

The horizontal fine grinding machine comprises a horizontal barrel, a grinding assembly and a separation assembly, a feeding port and a discharging port are formed in the horizontal barrel, the grinding assembly comprises a driving component, a cantilever shaft and a grinding disc, the first end of the cantilever shaft is connected with the driving component, and the second end of the cantilever shaft is connected with the separation assembly; the second end of the cantilever shaft extends into the horizontal cylinder, the grinding disc is arranged on the cantilever shaft, a shaft hole and a hollowed-out hole are formed in the grinding disc, the cantilever shaft penetrates through the shaft hole, the hollowed-out hole is provided with a first wall face and a second wall face, and the first wall face and the second wall face are oppositely arranged at intervals in the circumferential direction of the grinding disc. The projection of the first wall face and the projection of the second wall face are both in an arc shape, the curvature radius of the projection of the first wall face is larger than that of the projection of the second wall face, the separating assembly is arranged at the second end of the cantilever shaft, and the discharging port communicates with the interior of the separating assembly. The horizontal fine grinding machine is good in grinding effect and high in production efficiency.

Description

technical field [0001] The invention relates to the technical field of coal slurry grinding, in particular to a horizontal fine grinder. Background technique [0002] Coal water slurry is a coal-based liquid fuel and gasification raw material prepared by coal, water and additives in a certain proportion. As a liquid fuel, it can be used in industrial and power plant boilers to replace coal and oil. Synthesis gas is produced by coal slurry gasification, and chemical products such as ammonia, methanol, olefins, oil and natural gas are synthesized through subsequent processes. The coal-water slurry needs to be ground with a fine grinder in the preparation process, but the fine grinder in the related art has poor grinding effect and low production efficiency. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. [0004] For this reason, the embodiment of the present invention pro...
