PULVERIZER, METHOD FOR PULVERIZING BY USING THE SAME, METHOD FOR MANUFACTURING THE SAME

摘要

A pulverizer, a pulverizing method using the same, and a manufacturing method for the same are provided to improve the pulverizing efficiency by pouring raw materials stuck or settled down during a pulverizing process, into the center again. A pulverizer is composed of: an input unit(200) for receiving raw materials to be pulverized; a pulverizing unit(410) connected to the input unit through a first connecting pipe(300) to mill the raw materials; a classifying unit(450) disposed at the upper part of the pulverizing unit to classify the milled raw materials; and a collecting unit(600) connected to the classifying unit through a second connecting pipe(500) to collect the classified raw materials. The pulverizing unit comprises a spraying unit(431) for making the raw materials poured from the first connecting pipe, bump against each other into the center by jetting the high-pressure air and a guide unit(420) for guiding the raw materials stuck on the side wall or settled down on the bottom, to the center again by jetting the high-pressure air.
