Title:

BIOMASS CRUSHING DEVICE, AND SYSTEM FOR MIXED COMBUSTION OF BIOMASS AND COAL

Document Type and Number:

WIPO Patent Application WO/2013/046422

Kind Code:

A1

Abstract:

In order to efficiently discharge crushed biomass powder to the outside, the biomass crushing device body (13) of a biomass crushing device is configured in such a manner that the barrel section (21) at the center of the biomass crushing device body (13) in the vertical axis direction is reduced in diameter, and discharge pipes (22) for discharging the biomass powder (17) are provided in the circumferential direction at the top plate (13a) of the crushing device body (13), the top plate (13a) being located on a line extended from the vertical axis of the barrel section (21) reduced in diameter. In order to efficiently crush a biomass material, the biomass crushing device body (13) is configured in such a manner that the table liner (14b) of a crush table (14) comprises fan-like segments (31a, 31b), with the segments having different thicknesses in the height direction. The biomass crushing device is provided with a roller speed adjustment mechanism (71) which can adjust the rotational speed of a crushing roller (16) so that the peripheral speed of the crushing roller (16) is different from the peripheral speed of the crushing table (14).
