Abstract:
A system for manufacturing and separating dust-free manufactured natural sand and a winnowing separating method. The system comprises a PLC controller. Stones are conveyed to a feed port of a sand making machine (A) by using a stone conveying mechanism (A1), an exhaust port of the sand making machine (A) directly faces a start end surface of a manufactured-sand conveying mechanism (A2), a tail of the manufactured-sand conveying mechanism directly faces a feed end of a modular multi-layer vibrating screen (D), a discharge end of the modular multi-layer vibrating screen (D) directly faces a feed end of a manufactured-natural sand grading adjustment system (B), a discharge end of the manufactured-natural sand grading adjustment system (B) directly faces a feed end of a manufactured-sand winnowing system (C), and discharge ports of the manufactured-sand winnowing system (C) corresponding to manufactured-sand with different particle sizes are connected to respective storage tanks. The present invention can implement winnowing of manufactured-sand, and can also implement dust-free sand manufacturing.
