Detailed Description

Referring to fig. 1-3, the utility model provides a defeated coal pulverizer feed opening structure, include: a protective outer cover 2, a dust collector 3 and a spray frame 5.

And the protective outer cover 2 is positioned at the lower end of the blanking pipe 1, and the protective outer cover 2 is screwed on the side surface of the lower end of the blanking pipe through a fixed ring plate 21.
