Abstract:

PROBLEM TO BE SOLVED: To provide a vertical roller mill capable of more reliably preventing the penetration of rough particles into a classifier without providing a complicated mechanism such as a reject chute.SOLUTION: A vertical roller mill comprises: a cylindrical housing; a grind part which is provided in a bottom section within the housing and which grinds a matter to be ground; a classifier which is provided above the grind part within the housing; and a transportation mechanism which forms an upward flow for transporting the ground matter which has been ground by the grind part to the classifier, and comprises an annular guide part which is provided to have an annular shape along an inner wall surface of the housing between the grind part and the classifier, and which has an upward flow guide flow passage guiding the upward flow and a fallen ground matter guide passage guiding the ground matter falling from the classifier side while avoiding the upward flow guide flow passage.SELECTED DRAWING: Figure 1
