Abstract

The invention relates to a vertical roller mill air guide ring device, which comprises an air ring, an air guide ring, an air adjusting plate and an air flue, wherein the air ring is fixedly arranged at the upper part of the air flue through an L-shaped suspension plate; the air ring comprises an inner side annular plate, an outer side annular plate and a shutter guide plate; the shutter guide plate is located between the inner side annular plate and the outer side annular plate; an included angle of 63 degrees is formed between the shutter guide plate and the horizontal direction; the air guide ring is arranged on the outer side annular plate through a fastener and inclines by 75 degrees towards the center of a roller mill; and the air guide ring comprises an air guide plate, a connection plate and a reinforcing rib plate. By dopting the technical scheme, the ventilation area of the air ring is easily adjusted when different materials are ground; and the balance of the material amount in the mill and a gas in the mill is ensured, so that a stable material inner cycle number is formed in the mill. Meanwhile, the extension length of the air adjusting plate can be quickly adjusted at the air speed of the actual working condition of grinding different materials, and continuous production is not affected by exchange of the air adjusting plate and the air guide plate after the air adjusting plate is abraded, so that a pressure difference in the vertical mill is reduced; and the requirements of stable production and energy consumption reduction are met.

Description

technical field [0001] The invention belongs to the technical field of grinding equipment used in the cement industry, in particular to a vertical roller mill wind guide ring device. Background technique [0002] Vertical mill is an energy-saving grinding equipment widely used in cement, electric power, steel and other industries. During the operation of the vertical mill, the granular material is fed from the central feeding chute directly above the grinding disc, and the material falls on the center of the grinding disc. As the grinding disc rotates, the material is subjected to the action of centrifugal force and moves to the surroundings of the grinding disc in a spiral shape and enters the grinding area. During the crushing process, the material is simultaneously subjected to the pressure of the grinding roller and the shearing force generated by the relative movement between the grinding disc and the grinding roller. The ground material continues to move towards the ...
