Sand-making System

   The dry sand making system is developed and innovated on the basis of technologies such as crushing, screening and dust collection, which effectively improves the particle shape of finished sand and increases the proportion of finished sand. The technology of wind separation, vibration screening and sedimentation is combined to realize the effective separation of stone, sand and powder. Through intelligent control, the finished sand has good grain shape, particle size and grading. Help customers reduce costs and improve production efficiency. It has created new opportunities for the development of industries such as sand and gravel and commercial mixing.

　　1. Simple structure, low failure rate

　　Chute design, reduce transmission parts, simple and reasonable process,stable and reliable.

　　2. Good grain shape

　　The grain shape of the produced sand is uniform and round, which can be compared with that of natural sand (the grain shape can reach 58% to 59%).

　　3. Intelligent control

　　Fully automatic control, one-click start and stop, production data storage, dynamic interface display, easy to operate, manage and maintain. Video surveillance system, constantly monitor the working condition of equipment.

　　4. Green

　　All conveyor belts and pipelines are sealed and set up in the main corner of the small dust collector, crusher and powder separator, screening machine with centralized dust removal, effective control of dust pollution, equipment
does not need encapsulation, can achieve full environmental protection green production.

　　5. Adjustable moisture content

　　By using a humidifying mixer, the water content of the product can be adjusted as needed, and the same product can be produced as the wet sand making. Also good grain type.

　　6 · Fineness modulus is adjustable

　　The finished sand grading, fineness modulus, powder content can be easily adjusted on the equipment, the grain shape is excellent hexahedron, and then product quality is stable. It can be used for high speed, railway, subway, precast concrete and high grade highway asphalt concrete.

　　7. Compact layout and small footprint

　　Tower-like design, compact layout, small footprint, beautiful factory and weatherproof.

      Raw materials below 15mm (can be stone chips, guamite, stone powder and other cheap and easy to get raw materials) after VU impact breaking and finishing, under the action of mold control screen and dust removal module, it
is divided into three ways: stone powder, return material and semi-finished sand. After the dust removal module, the stone powder is uniformly stored in the powder ore bin, and the quasi-finished sand enters the grain optimization
machine for further shaping, and the processing is completed after humidification and mixing.

　　After the raw materials are processed reasonably and perfectly by VU system, the fine machine-made sand with reasonable grading, round grain shape and controllable powder content is produced, as well as the dry and clean fine
stone powder that can be uniformly recycled (the scope of application is determined according to the raw materials).
