Claims

[Scope of utility model registration request]

Inside the casing, a circular rotary table is pressed against the outer periphery of the top surface of the table and rotated in contact with it;
It is equipped with a plurality of rollers that crush raw materials and a classifier that is installed above the table to separate coarse particles from fine particles. In a vertical roller mill, the coarse particles are blown up by a blow-up nozzle section, guided to a classifier, and then the separated coarse particles are fed back onto the table. 1. A vertical roller mill comprising a plurality of gates arranged adjacent to each other and each having an arcuate tip, the blowing nozzle gap being able to be adjusted from the outside of the casing using the gates.
