Description

Technical Field

[0001] The utility model belongs to the technical field of silicon dioxide, and in particular relates to silicon dioxide coarse grinding equipment for reducing dust. Background Art

[0002] Silicon dioxide is an inorganic compound with the chemical formula SiO2. Silicon atoms and oxygen atoms are arranged in a long-range orderly manner to form crystalline silicon dioxide, while short-range orderly or long-range disordered arrangements form amorphous silicon dioxide.

[0003] In a silicon dioxide crystal, the silicon atom is located at the center of a regular tetrahedron, and four oxygen atoms are located at the four vertices of the tetrahedron. Many such tetrahedrons are connected through the oxygen atoms at the vertices. Each oxygen atom is shared by two tetrahedrons, that is, each oxygen atom is combined with two silicon atoms.

[0004] The production of silica requires that the silica ore (obsidian) be placed in a coarse crushing equipment for crushing. However, the powder produced by the crushed silica will enter the air and float in the air, making it easy for workers to inhale the silica in the air into their bodies. Utility Model Content
