The requirements for raw materials to produce glass quartz sand

There are two main raw materials for producing glass quartz sand, one is lump quartz stone, the other is natural granular silica sand, two kinds of raw materials through a series of processing technology, can produce glass sand to meet the requirements.

Processing flow of glass quartz sand

The quartz sand processing flow should go through all or part of crushing - screening - grinding - classifying - scrubbing - desliming - gravity separation - magnetic separation - flotation - dewatering. If the raw material is granular silica sand, there is no need for crushing and grinding, and it can be directly sent into the subsequent production process. The main purpose of quartz sand processing is to remove clay and other impurities, improve the content of quartz sand, reduce the content of Fe2O3 and impurities, and control the particle size in a certain range. Different raw materials, the use of processing technology will be different, typical glass sand production processing flow is shown as the following figure.

Crushing and grinding

The lump quartz stone should be crushed into<20mm particle size by jaw crusher and cone crusher, and then into the rod mill for grinding, the ground quartz sand sent to the classifying system. If the raw material is granular silica sand, it can be directly entered into the classifying system after screening.


After grinding, the sand slurry enters the hindered settling machine to separate the coarse sand to return to the rod mill for regrinding, and the overflow enters the hydraulic classifier to separate the fine sand. In this way, the sand is separated out of a certain size range through hindered settling machine and hydraulic classifier, and then it can enter the next step of scrubbing and desliming system.

Scrubbing and desliming

The classified quartz sand enters the attrition scrubber to fully dissociate the impurities covered on the surface of the quartz sand, effectively removing the residual clay and impurities, and effectively removing the iron oxide material wrapped on the surface of the sand particles.

Magnetic separation

After scrubbing the iron material in sand shall be removed through the magnetic separation system. Firstly using drum magnetic separator with medium magnetic field intensity to remove strong magnetic iron material, and then use high gradient magnetic separator with high magnetic field intensity to remove weak magnetic iron material. Remove as much iron material as possible from the quartz sand.

Gravity separation

If the sand contains heavy minerals such as TiO2, the spiral chute needs to be used to remove the heavy minerals. Feed the sand slurry into one stage or multi stages spiral chute group to separate heavy minerals and obtain qualified glass sand products.


In order to further improve the content of SiO2 and reduce the content of iron, the grade and quality of quartz sand should be further improved by flotation. Using quartz sand flotation machine, adding appropriate reagents, the residual impurities and iron material in the quartz sand are removed to obtain high quality glass quartz sand

In addition to the above processing technology, acid scrubbing, leaching or pickling, gravity separation and other processes should be arranged according to the situation of raw materials to remove residual iron materials and heavy minerals, so that the final product meets the requirements.

Sinonine's glass sand washing plant is of cost-effective and the world's advanced level, which can make full use of the quartz sand raw materials, and will take appropriate processes to produce the best glass sand products according to the quality of the raw materials.The Sinonine glass sand production line can meet the production capacity of 30-500tph, from lab-scale test, design, equipment manufacturing to the final production line installation guidance, trial run and commissioning, Sinonine can provide a full range of services on a turnkey basis.















Sinonine sand washing plant can be applied to various sand production fields to clean, remove impurities, screen, grade, dewater. Sand products used in the different areas can be produced by different sand washing systems. Sinonine has developed a series of sand washing systems for construction, foundry, glass making, and oil fracturing, etc for processing different kind of sand, such as quartz, artificial sand, dune sand, river sand and other raw sand.
Sinonine high purity quartz sand production line is used to produce high purity and ultra-high purity quartz sand with SiO2 content higher than 99.999% for the production of quartz crucible and high-end electronics industry. Selecting the appropriate quartz stone as the raw material and processed in the high purity sand production line, through a series of purification processes the high purity quartz sand is obtained, an annual output of 3000-50,000 tons of large-scale industrial production capacity can be achieved. Sinonine owns the state-of-art technology in HPQ purification at the world's leading level.

The impact crusher is used for medium and fine crushing of stones. The design of Sinonine impact crusher adopts novel design principle, new concepts of crushing technology; meets demands of crushing different materials in different degrees. Sinonine Impact crusher not only has a great crushing ratio and fine products of uniform shape, also consumes less power per unit. The unique design of impact lowers its cost of repair and maintenance, thus improves its productivity and reduces its cost. Impact crusher proves the bright prospect of its application in mining processing industry through large scale projects.

Jaw crusher is primary crushing equipment in stone crushing line. Sinonine Jaw Crusher is of single toggle type with features of simple structure, easy maintenance, stable function, low operation cost, great crushing ratio. Jaw Crusher is used widely in mine, metallurgy, construction, road, railway, hydro-electric, and chemistry. It is suitable for the primary or secondary crush of large rock with compressive resistance no more than 320MPa. PE type is used for coarse crushing, and PEX type is used for fine crushing.
Apron feeder is to transport ore to primary crusher for evenly and continuously feeding. Apron feeder is important in ore feeding and conveying system, and also for short distance material delivery. Apron feeder is especially appropriated for transporting materials with large proportion, large particle size, and strong abrasiveness, and can work reliably in the open air, humidity and other harsh conditions. Apron feeder can be widely used in metallurgical, mining, cement, and building materials. Both horizontal and oblique installation is ok for apron feeder, the maximum installation angle of apron feeder can reach 25º.
VSI sand making machine is the latest successful crushing machine with the international advanced technology. Many years technology accumulation and modern processing equipment ensure the leading position of the VSI sand making machine in this industry. Excellent cost performance and reliability make VSI sand making machine outstanding in the similar products. VSI sand making machine is the perfect combination of the latest research result of Germany and Chinese present working conditions. It is currently the exclusive production sand making machine with the worlds advanced level.
