Abstract: Provided is a vertical-type mill whereby abrasion of a hopper and accumulation of coarse particles in the hopper can both be prevented. A vertical-type mill provided with a milling mechanism for milling a material to be milled and obtaining solid particles by meshing of a milling roller or milling ball and a milling table, a classification mechanism having a classifier for classifying milled solid particles and a hopper (11) for collecting coarse particles that are classified by the classifier and dropped downward and leading the coarse particles toward the milling mechanism, a raw material feeding pipe (1) for charging the material to be milled into the milling table, and housings (43a, b), wherein the raw material feeding pipe is provided in the hopper so that the relationship 0.15?L?/L?0.
