The production process of ore sand making machines is actually a precise assembly line operation. The core objective is to efficiently process lumpy ore into manufactured sand that meets particle size requirements. The entire process is mainly divided into several key stages: crushing, screening, sand making, washing, and recycling.
Core Production Process Flow
Coarse Crushing: Large pieces of ore are first crushed using a jaw crusher, reducing the particle size to approximately 100-200mm.
Medium Crushing: The coarsely crushed material undergoes secondary crushing using a cone crusher or impact crusher, further reducing the particle size to 20-50mm.
Screening: The crushed material is graded using a vibrating screen. Material meeting the particle size requirements is screened out, while material not meeting the requirements is returned for further crushing.
Sand Making: The screened material enters an ore sand making machine (such as an impact crusher) for fine crushing and shaping, achieving particle crushing and shaping through the "stone-on-stone" principle.
Washing and Recycling: After sand making, the material is washed by a sand washing machine to remove impurities, then dewatered by a dewatering screen to obtain the final manufactured sand.
Key Equipment and Technical Points:
Stone-on-Stone" Technology: This is the core of the impact crusher. Materials collide and crush each other within the crushing chamber, effectively reducing wear on metal parts. It is particularly suitable for processing medium-hard, extra-hard, and abrasive materials.
Closed-Loop Circulation System: The entire production line typically uses a closed-loop circulation system. Materials are repeatedly screened by a vibrating screen, and unqualified materials are continuously returned to the crusher until the required particle size is achieved.
Particle Size Control: The particle size of the finished sand is usually precisely controlled by adjusting the crusher discharge port, screen mesh size, and the rotor speed of the sand making machine.
