Significant technological upgrades have been achieved. The mainstream equipment adopts the dry process of “crushing grinding screening electrostatic sorting”. After being refined to 24 mesh powder by a water-cooled vortex wheel mill, it is separated by a double roll shaft electrostatic sorting machine using conductivity differences, and the purity can reach over 99%. By 2024, the average separation efficiency of the equipment will reach 95%, with energy consumption decreasing by 18% compared to 2020. It is expected to increase to 98.5% by 2025. Some high-end models also introduce IoT technology to achieve remote monitoring and fault warning.
The application value combines environmental protection and economic attributes. Hangzhou Fulun Ecological Technology processes 200000 tons of waste annually. After separation, aluminum can be recycled and plastic can be used to produce new materials. The COD removal rate of wastewater exceeds 97%. The investment return cycle of equipment is only 6-12 months, and the shipment volume in East China accounts for 38.7%, becoming the main force in the market.
Under the promotion of the “dual carbon” policy and the construction of waste free cities, the equipment market is expected to achieve double-digit growth in 2025, and the export value will increase by 12.8% year-on-year. This’ waste to treasure ‘equipment is becoming an important support for the circular economy.
