Silica is a general term for vein quartz, quartzite and quartz sandstone. It is mainly used in acidic refractory bricks for the metallurgical industry. Pure silica can be used as quartz glass or to refine monocrystalline silicon. The appearance of crystallized silica is generally creamy white, grayish white, light yellow and reddish brown. It has a distinctive luster, smooth and continuous cross-section with sharp edges, and great hardness and strength. Vein quartz is a dense block, pure white, translucent, greasy luster, the section is shell-shaped, quartz crystallization particles are more than 2mm, discernible with the naked eye.
Grinding Production Line
The first stage: the drying of silica: silica vertical mill according to the moisture content of the situation, through the dryer or to the mill through the way of hot air for the drying of raw materials.
The second stage: silica vertical mill feeding: silica grinding and crushing of silica small pieces of material through the elevator to the storage hopper, and then through the feeder will be uniformly quantitatively fed into the LM vertical mill grinding chamber for grinding.
The third stage: grinding and grading: the fine powder after grinding by the silica vertical mill is graded by the grading system, and the unqualified fine powder powder is graded by the grader and returned to the host of the vertical mill for re-grading.
The fourth stage: the collection of finished products: the powder that meets the fineness is separated and collected with the airflow through the pipe into the dust collector, and the collected finished powder is sent to the finished product bin by the conveying device through the discharge port, and then packaged uniformly with the powder loading tanker or automatic baler.
