Refined quartz sand production process is common: dry and wet method.
Quartz sand produced by dry method can be divided into three grades: ordinary quartz sand, semi-refined quartz sand and refined quartz sand.Due to the natural quartz stone surface is yellow-brown, choose a smaller quartz stone mineral material directly crushing sieve products called ordinary quartz sand, the surface appears yellow-brown and white alternate with, its advantage is cheap, the disadvantage is more impurities, so it is used in the construction industry;Selected out of the larger quartz ore for processing known as semi-refined quartz sand, the surface appears white, but dotted with yellow-brown spots, the product price moderate, better quality, so the scope of wider application.Selected out of the bulk of quartz ore, after artificial removal of the surface of the yellow brown skin reprocessing is refined quartz sand, the surface appears white, shiny as sugar.Because the processing process takes time and materials, so the price is higher.
Wet quartz sand production line is mainly equipped with jaw crusher, cone crusher (or fine jaw crusher, or impact crusher), quartz sand machine, sand washing machine, dryer and so on.The process flow is roughly quartz stone by coarse crushing, fine crushing until sand, sand washing machine cleaning, after drying with a dryer, and then use vibrating screen screening, screening process for iron removal.Wet quartz sand can maximize the purity of refined quartz sand, taste high, so the price is high!
Acid washed quartz sand production process is common only one: weak acid treatment.
The production environment of acid washed quartz sand is mostly in pure water or desalted water. First of all, it has to be treated with weak acid. The reason why it needs to be treated with weak acid is that there will be no qualitative change in the water system because of the content of some substances in the water.The quality of quartz ore determines the concentration of hydrochloric acid and soaking time during pickling.Next is crushing, now the quartz sand production equipment is one, the ore into the equipment is out of the finished product.But acid washed quartz sand is not suitable for this equipment, because the ore crushing can not directly into the vibrating screen, but to enter the acid pool, so is not suitable for the integrated equipment.Hydrochloric acid concentration is generally about 30% can be soaked in 24 hours or so the best time.After soaking the quartz sand has no impurities, and the color becomes crystal clear white, and finally is the screening and washing, screening and washing in a set of equipment to complete.The resulting quartz sand is optimal for reverse osmosis and desalination equipment.
Compared with the pickling quartz sand, the pickling sand needs to be calcined at 900 degrees, and then the water quenching can make the internal micro cracks for pickling, which can be crushed by ball mill or ramon mill, and finally acid pickling with hydrochloric acid, hydrofluoric acid and sulfuric acid mixture. The purpose of pickling can be achieved by stirring for 24 hours while soaking.
