| Abstract: | The weighing and charging accuracy of direct charging and pressing for powder charging adopts the metering plate fixed capacity charging and liberation technology. The NAMUR capacitance sensor which installed under the charging filter monitors the powder capacity momentarily. Liberation charging structure consists of pulse generator and film crock which under the filter and metering plate and modulates the liberation frequency by pulse generator. The pressure deepness and pressure density adopts the whole closed-loop and whole digital gas-liquid servo technology. The pressure realizes online real time detection and control in pressuring process. |
