Requirements of sandblasting process for quartz sand

Sandblasting is a process of cleaning and roughening the surface of the substrate by the impact of high-speed sand flow. Compressed air is used as the power to form a high-speed jet beam to spray the material (copper ore sand, quartz sand, corundum, iron sand, Hainan sand) at high speed to the surface of the workpiece to be processed, so…

300,000 tons of photovoltaic quartz sand production line in the desert

Recently, the Ganqika sand mine's annual production of 300,000 tons of photovoltaic sand and 200,000 tons of low-iron feldspar production line project started full-line trial production. At present, all production processes are stable and orderly and operating normally. In the production workshop of the project, after the raw ore is fed, the sand material passes through the "physical section", "flotation…

What purity of quartz sand is needed for silicon carbide plants?

Silicon carbide production requires the use of quartz sand with a purity higher than 99.5%. LZZG quartz sand purification equipment can meet this standard. Quartz sand purity standards The quality of quartz sand is mainly composed of purity and particle size. In order to ensure the production quality of silicon carbide, the quartz sand used must meet the following purity…

Flotation removal of mica from quartz sand

Quartz sand flotation mainly includes fluorine flotation and fluorine-free flotation. Among them, fluorine flotation uses cationic collectors and hydrofluoric acid activators to operate in an acidic pH range. Its disadvantage is that fluoride-containing wastewater seriously pollutes the environment and needs to be treated before being discharged. Fluorine-free flotation takes advantage of the differences in the structural composition of quartz and…
