Features of sand picking unit

1.Environment-friendly, the acid pickling reaction of silica sand is carried out in a closed reaction tank, without the leakage of acid gas and acid liquid, which will not cause any impact on the environment;

2.The temperature is constant during the system reaction, and the reaction effect is good;

3.Small floor space and large capacity of the reaction workshop;

4.Simple and convenient operation and less labor.

Working principle of sand picking unit

The acid solution with required concentration and silica sand are put in the reaction tank. The boiler circularly heats the acid liquid and silica sand at a certain period of time and temperature, and then the acid solution after the reaction is discharged. High-purity silica sand can be obtained after the subsequent washing operations.

Case 1:China Hubei Silica sand pickling equipment

The customer employed A set of Silica sand pickling equipment to produce high-purity quartz sand for making slabs. After A period of reaction, impurities in the Silica sand were dissolved to obtain class A quartz slab sand products.

Case 2:China Anhui Silica sand pickling equipment

Dozens of Silica sand pickling equipment were installed in a Silica sand production line to further purify Silica sand and finally Silica sand with SiO2 content of 99.94% was obtained.

For quartz sand pickling, Sinonine's experience is very rich. The purification of quartz sand by pickling is a technology-intensive work. Sinonine will conduct experiments on quartz sand samples in advance, determine the concentration of chemicals used and pickling time to guide the process design and actual production.The structure of Sinonine pickling equipment is very simple and the layout is very reasonable. The whole process of production is closed and the pickling can be completed in a very short time. The production efficiency is very high and the production cost is very low. After pickling, the quartz sand has high whiteness and purity.


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. VSI sand making machine is suitable for crushing and shaping soft or middle-hard or extremely hard materials, widely applied to pebble, rocks (limestone, granite, basalt, dolerite, andesite), iron ore tailing, artificial sand making of stone chips. VSI Sand making machine is also applied to water conservancy and hydropower of engineering field, high-grade highways, expressway and railway, passenger railway, bridge, airport pavement, municipal engineering, sand manufacturing and aggregated rock shaping.
