The system includes equipment and modules such as impact crusher, mold-controlled screen, particle optimizing machine, humidification mixer, dust collector, central control system, steel structure, etc. It is a complete dry sand production solution. Raw materials below 15mm (which can be cheap and easily available raw materials such as stone chips, guar rice stone, stone powder, etc.) are crushed and shaped by impact crushing, and then divided into three routes under the action of the mold-controlled screen and dust removal module: stone powder, returned materials and quasi-finished products. sand. After passing through the dust removal module, the stone powder is uniformly stored in the powder ore bin. The semi-finished sand enters the particle optimization machine for further shaping, and is humidified and stirred to complete the processing. After the raw materials are processed reasonably and efficiently in the system, high-quality machine-made sand with reasonable gradation, rounded grain shape and controllable powder content is produced, as well as high-quality stone powder that is dry and clean and can be uniformly recycled (the scope of application is determined according to the raw materials) .
