ESTRUCTURA DE MOLINO TRITURADOR.

摘要

A roller mill structure which achieves uniform distribution of fine particles passed through a rotary classifier to fine particle exits disposed at four points when conveying as pulverized coal milled in the roller mill on the air current is provided. A roller mill structure is configured to discharge pulverized coal obtained by milling a raw coal, which is loaded in a mill body (11), from fine particle exits (14) formed on the top of the mill body so as to be quartered in the circumferential direction to the outside by air current conveyance. The roller mill structure includes a table which rotates in the mill body (11), three rollers for rotating on the table and milling the raw coal, and a rotary classifier (20) disposed upstream of the fine particle exits (14), wherein a movable vane (21) for partly narrowing the cross-sectional area of a flow channel is provided at a midpoint of the flow channel for fine particle current flowing into the interior of the rotary classifier (20), and proceeding toward the fine particle exits (14).
