Silica is the collective name for vein quartz, quartzite and quartz sand. Mainly used for acid refractory bricks used in the metallurgical industry. Pure silica can be used as glass or as refined monocrystalline silicon. Silica is an important chemical raw material with high hardness and can be used in metallurgical industry, building materials industry and other chemical industries after being ground into powder.
Can vertical mills process silica powder?
Vertical mills can process silica powder. From stone to powder, silica needs to be pulverized and ground, and the silica pulverizer is the main processing equipment, which is used to grind the pulverized silica into silica powder of different meshes. Vertical mill is a commonly used grinding equipment, of course, it can also be used for the processing of silica powder.
Vertical mill is also called vertical pulverizer, which integrates crushing, drying, grinding, grading and conveying. , slag as the focus.
What are the processes of silica grinding?
Working principle: The motor drives the grinding disc to rotate through the reducer, the material falls into the center of the grinding disc from the feed inlet, and the hot air enters the mill from the air inlet. Under the action of centrifugal force, the material moves to the edge of the grinding disc, and is crushed by the grinding roller when passing through the annular groove on the grinding disc. The crushed material is carried by the high-speed airflow at the air ring at the edge of the grinding disc, and the large particles fall directly on the grinding disc. Re-grinding, when the material in the airflow passes through the dynamic and static separator, under the action of the rotating rotor, the coarse powder falls on the grinding disc for re-grinding, and the qualified fine powder is ground together with the airflow and collected in the powder collecting device, which is product. Moisture-containing materials are dried during contact with hot gas to achieve the required product moisture.
