Today’s Patent – Device for Preparing Artificial Aggregate by Pressure Injection and Solidification of Powder-Based Solid Waste, Pelletization, and Magnetic Shell Reinforcement

The said invention (US12202022B1) was invented by Hailong Wang, Huanjie Su, Yaolu Chen, HuiJun Xue  and patented by USPTO on May 22^nd, 2024. Currently, it stands assigned to the Inner Mongolia Agricultural University.

The disclosed device enables efficient preparation of artificial aggregates using powder-based solid waste through a sequential process of pressure injection, pelletization, sintering, and magnetic shell reinforcement. It comprises interconnected modules—pressure injection and solidification, rolling particle screening, zonal temperature-controlled sintering, and magnetic shell reinforcement—linked by conveyor belts. Key features include slurry injection into aggregate cores for enhanced performance, elastic wheel sets for pressure-based forming, zonal microwave sintering for improved durability, and a magnetic shell reinforcement system using steel balls and electromagnets for surface strengthening. The system ensures efficient shaping, minimal waste, and high-strength, uniform aggregates suitable for construction use.
