The VU dry sand making system adopts a highly intensive tower-style fully enclosed layout, which integrates sand making, particle shape optimization, stone powder control, gradation adjustment, moisture content control, and environmental protection treatment. It not only significantly improves production efficiency, but also realizes the mechanism The improvement of various indicators such as sand grain type, gradation, and powder content makes the performance of machine-made sand comparable to natural sand, creating new opportunities and values for the development of sand, cement, and concrete industry chains.

Scope of application: supporting sand making in mixing plants, dry-mixed mortar, cement product factories, aggregate mines, large-scale construction projects, etc.

Working principle: The raw material is sent to the VU impact crusher through lifting, and then enters the mold-controlled sieve after being ground by high-frequency stone-beating stone. After sorting, according to the sieving results, the material on the sieve returns to the VU impact crusher for processing, and the material on the sieve enters the VU grain refiner for processing. Material reshaping, while the entire mold control sieve controls the powder content in the material through the wind selection of the dust collector, and finally the VU particle refiner discharges the material and mixes the material evenly through the humidifying mixer. After being processed by the VU aggregate optimization system, the finished sand with reasonable gradation, round grain shape and controllable powder content is produced, as well as dry and clean high value-added stone powder that can be recycled uniformly.
