JNW Energy-Saving King Asphalt Mixing Plant
1. The hot-material bins feature an intelligent, patented structure that accurately displays the material level in each bin and automatically controls the supply of cold materials, thereby eliminating overflow of hot aggregates and reducing energy losses. 2. The application of this patented intelligent hot-material-bin technology resolves the drawback of lengthy cumulative weighing times associated with conventional hot aggregates, significantly shortening the batch cycle and substantially increasing production output. 3. The implementation of this patented intelligent hot-material-bin technology enables automatic, seamless integration between the stock levels of hot aggregates and the cold aggregate gradation, ensuring a smooth and efficient hot-aggregate metering process. 4. Aggregate metering employs small-door, low-flow, and decremental weighing techniques, effectively eliminating “fly-off” during weighing and achieving dynamic metering accuracy for hot aggregates within 1% (the national standard is 2.5%).
