Weiliang Gyratory Screen in Sieving Fine Sand

Natural sand is produced by natural forces, such as river sand, sea sand, and mountain sand.

Natural Sand

Generally, mountain sand is more weathered, containing more mud, organic impurities and light substances. Sea sand often contains shells and other impurities, and its components such as the chlorine, sulfate and magnesium salts may cause corrosion of steel bars. All the components will affect the performance of concrete.

Therefore, the quality of river sand is the best and suitable for construction among natural sand.

River sand is a kind of non-metallic ore with complex composition and smooth surface that generated by repeated collided and rubbing in water for a long time in a natural stone state. River sand particles are smooth, relatively clean and with wide source.

River Sand Production Line

The river sand production line is different from the artificial sand production line, it has no crushing step. River sand is usually washed in water at the front for cleaning and coarse screening purposes. The wet sand is conveyed evenly into the sand drying system to remove the moisture content of the sand. The dry sand is then conveyed to a WEILIANG SZF LINEAR VIBRATING SCREEN for coarse screening and then evenly to a WEILIANG FYBS GYRATORY SCREEN for fine screening to get the desired size.

Linear screens are not always necessary, we have some customers who only use gyratory screens for sieving on site, depending on the characteristics of the sand.

What Do We Offer

Screening system in sand production line

Artificial Sand

Artificial sand also called manufactured sand or crushed sand or mechanical sand, manufactured by crushing rocks, stones or larger aggregates into small size particles in the quarry.

It is processed by mechanical crushing and sieving with consistency to be used as a substitute for river sand.

Artificial Sand Production Line

Artificial sand production lines are divided into dry sand production line and wet sand production line, which are distinguished by sand washing systems.

Artificial sand making production line usually consists of vibrating feeder, primary crusher (jaw crusher), secondary crusher (impact crusher), sand making machine, vibrating screen, sand washing machine, belt conveyor system, centralized electric control box and other equipment. The configuration can be altered accordingly.

Dry Artificial Sand Production Line

The vibrating feeder feeds the stone evenly into coarse crushing machines (jaw crusher) for primary crushing. And then the crushed stone is conveyed to the fine crushing machines (impact crusher or cone crusher) through belt conveyor for secondary crushing.

The material produced by impact crusher needs to be further processed by sand making machine to proceed the finest-crushing stage. The finely crushed material is then screened into coarse sand, medium sand, fine sand and other specifications by WEILIANG FYBS VIBRATING SCREEN.

Wet Artificial Sand Production Line

Water is involved in the entire sand and gravel aggregate production process as the working medium and dust suppression measure of the wet sand production line.

The upstream of the wet process line is the same as the dry process. The material from vibrating screen is sent to the sand washing machine by the belt conveyor to remove dirt, dust, and other impurities. And the sewage discharged from sand washing machine can be recycled by fine sand recovery plant.

During the sand making process, the oversized particles are returned to the sand making machine to be reshaped into smaller particles and then sent to the vibrating screen again for screening, thus forming a closed circuit for multiple cycles.
