High-purity Quartz Sand Production Process


High-purity quartz sand is a kind of stone that is carefully selected and finely processed using natural crystal stone, silica, and quartzite. It can be used to make all kinds of glass, as a water treatment filter, or as ceramics and refractory porcelain. The billets and shafts. The production process of high-purity quartz sand is beneficiation, crushing, screening, cleaning, grinding, impurity removal, drying and packaging. Let's take a look with the editor.

The quartz sand beneficiation process is mainly to remove impurities and purify, remove a small or tiny amount of impurities in the quartz sand, and obtain a highly difficult separation technology for refined quartz sand or high-purity quartz sand.

Quartz sand technology mainly includes quartz sand impurity analysis and impurity removal technology, quartz sand purification technology and so on.

1. Beneficiation

High-purity quartz sand is generally made of silica, quartzite or natural crystal stone. The raw materials are manually crushed, sorted, sorted, and put into the silo.

2. Broken

Generally, jaw crushers, impact crushers and sand making machines are used for crushing operations. Quartzite is continuously and uniformly fed into the jaw crusher by a vibrating feeder for coarse crushing. After coarse crushing, the quartzite is crushed by a belt conveyor It is sent to the sand making machine for fine crushing.

3. Screening

Use a circular vibrating sieve to screen out qualified sand and gravel. Quartz sand with a particle size of less than 1mm is sent to the sand washing machine to clean the stone powder and dust. Quartz sand with a size of 6mm or more is sent to the crushing system again, and the impact crusher or sand making The machine re-crushes, the screening and cleaning system and the crushing system together form a tight and ingenious closed loop.

4. Cleaning

Put the accepted sand and gravel into the cleaning tank according to the process standard and decontaminate with clean water to wash away the impurities attached to the surface of the ore. Operators must wear clean protective water boots when cleaning.

5. Grinding

Quartz sand is ground for ore dressing and impurity removal to produce high-purity quartz powder.

6. Removal of impurities
