Grinding system of micro-negative pressure raymond mill

Abstract

The invention relates to a grinding system of a micro-negative pressure raymond mill, which is characterized in that a raymond mill is connected with a powder gathering device that is connected with ablast blower by a return vent pipe that is provided with a regulating valve I, the blast blower is connected with the raymond mill by an air inlet pipe that is provided with two outlets, one of whichis sequentially connected with a regulating valve II and a pulsed dust collector by a rest air pipe, and the other one thereof is sequentially connected with a regulating valve III and atmosphere byan air supplement pipe; the air supplement pipe is arranged on an outlet of the air inlet pipe at an inlet of a ring-shaped horizontal air box. Micro-negative pressure pneumatic structure can be formed inside a host machine of the raymond mill by accurately regulating the regulating valve I, the regulating valve II and the regulating valve III. The invention has the advantages of greatly improvingthe quality of working environment of operating workers and surrounding area, leading the yield of the raymond mill to be increased by approximate 25%, and generating great economic benefit.

Description

Micro Negative Pressure Raymond Mill Grinding System technical field The invention relates to the field of powder processing, in particular to a micro negative pressure Raymond mill grinding system. Background technique With the increasing progress of society, people have higher and higher requirements for the quality of production and living environment. More and more people are aware of the importance of the environment. Environmental issues have developed to the height of a country's national policy. Raymond mill is a widely used grinding machine. The fineness of its products is generally 325-400 mesh. Its main disadvantages are: the main machine operates under positive pressure, and a large amount of dust is emitted during the production process. Seriously affected the health of the operating workers and the environmental quality of the surrounding areas. Contents of the invention The purpose of the present invention is to provide a micro-negative pressure Raymond ...

AI Technical Summary

Problems solved by technology

The purpose of the present invention is to provide a micro-negative pressure Raymond mill grinding system, so that the aerodynamic pattern in the main machine of the Raymond mill is changed from positive pressure to micro-negative pressure, and solves the problem of dust pollution in the production process
