Vietnam has a population of near 1000 million. Yunnan is carrying out infrastructure construction all over the country. Experts that the country could run out of sand within five years due to over-exploitation of the natural product, local media reported. The artificial sand can be used to instead the natural sand. It was produced by sand making and sand washing machine . artificial sand has many advantages such as: The factory production can establish a quality control system from a series of processes such as material selection and crushing. The physical and mechanical properties of sand can be consciously selected to produce hard rock sand, avoiding the use of soft, weathered rock, and the amount of mud (block) can be manually screened. The artificial sand is 10~20% cheaper than natural sand. The particle grading and fineness modulus of the mechanism sand can be adjusted. According to the needs of the project, combined with the characteristics of the base metal and

The fine sand recovery system consist of screw sand washing machine , vibrating screen , cyclone. The vibrating Screen was combined with cyclones. Ordinary sand wheel washer or screw sand washing machine can’t process fine sand below 3mm, we researched vibrating screen with cyclone machine.   sand recycling system The cyclone is a separation and classification device. When the two-phase mixture to be separated is tangentially introduced into the cyclone from a periphery of the cyclone at a certain pressure, a strong three-dimensional elliptical strong rotational shear turbulent motion is generated. Lzzg's dewatering screen https://www.lzzgmachine.com and sand recovery machine have excellent performance. Compared with Yunnan's local ordinary vibration dewatering screen, the sand washing machine output is twice as high, which greatly improves the production efficiency of the whole line.

Sand washing machine is an indispensable equipment in sand and gravel mining, mining, building materials, transportation, chemical, water conservancy and hydropower, concrete mixing stations and other industries. The most common sand washing machines are spiral sand washers, drum sand washers, wheel sand washers, and vibration sand washers. working principle of sand washing machines XSD Wheel Sand Washing Machine During operation, the motor drives the impeller to rotate slowly. The sand enters the washing tank through the feeding trough, rolls under the impeller, and grinds each other to remove impurities covering the surface of the gravel, and destroys the water vapor layer covering the sand to facilitate the water vapor layer. Dehydration.  At the same time, water is added to form a strong water flow, and foreign matter with a small impurity and a small specific gravity is taken away in time, and discharged from the overflow port to complete the cleaning.
