Abstract

The invention relates to a vertical grinding mill. The vertical grinding mill comprises a base, a milling mechanism and an airflow classification machine, wherein the milling mechanism and the airflow classification machine are arranged on the base. The airflow classification machine comprises a machine body and a plurality of rotors vertically arranged on the machine body; the rotors comprise blades and are divided into two or more groups, blade clearances and / or rotating speeds of the rotors in different groups are different, and therefore products with different granularities can penetrate; the products with the same granularity penetrate the rotors in each group, and the rotors in each group are connected with the same discharging pipe; and in the airflow classification machine of the vertical grinding mill, according to the differences of the blade clearances and / or the rotating speeds, the rotors are divided into two or more groups, the rotors in each group are connected with the same discharging pipe, the blade clearances and / or the rotating speeds of the rotors in different groups are different, the granularities of the products penetrating the rotors are different, and a plurality of granular products can be obtained at the same time.

Description

technical field [0001] The invention relates to a vertical mill. Background technique [0002] Due to the advantages of simple grinding mechanism, convenient operation, and low requirements for materials, the vertical grinding machine has been widely used in recent years, and it is necessary to design a reasonable airflow classification mechanism to cooperate with the grinding mechanism. . [0003] The Chinese patent document with the announcement number CN203842820U and the announcement date of September 24, 2014 discloses a vertical multi-rotor air classifier, including a body and a plurality of rotors erected on the body, the rotors include blades, and all rotors The upper end is connected with a total discharge port, and the fine particles are milled from the total discharge port. This airflow classifier has the problem that the obtained product has a single particle size. Contents of the invention [0004] The object of the present invention is to provide a vertical...
