Document Type and Number:
Japanese Patent JP7362253
Kind Code:
B2
Abstract:
To provide a solid fuel crushing device that can detect coarse-grained solid fuel piled inside a rotary classifier.SOLUTION: The solid fuel crushing device comprises: a rotary table 12, a roller 13 that crushes solid fuel between the rotary table 12 and the roller; a classifier 16 that comprises a plurality of classifying vanes 16a, erected along a circumferential direction with respect to a fixed part 16b, which rotate with a rotary shaft line as a center, and classifies the crushed fuel crushed by the roller 13a; a discharging port 19, connected to an inside SP1 of the classifier 16, inner peripheral sides of the plurality of classifying vanes 16a erected in the circumferential direction, through which the finely-divided fuel classified by the classifier 16 is discharged; and a differential pressure detection part 43 that detects differential pressure between pressure of the inside SP1 of the classifier 16 and pressure of an outside SP2 of the classifier 16.SELECTED DRAWING: Figure 2
