MATERIAL PULVERIZING SYSTEM

摘要

MATERIAL PULVERIZING SYSTEM A material pulverizing system includes an air-swept pulverizing mill that produces and delivers pulverized material to utilization apparatus at a variable mill output rate determined by a variably and independently controlled air flow. The pulverizing system includes a pulverizable material feeder that delivers raw material to the pulverizing mill at a variable and controlled rate to establish and maintain the stable and efficient operation of the pulverizing mill at any mill output rate. The pulverizing system further includes automatic control apparatus that controls the material feeder at a rate determined by the power consumed by a motor driving the pulverizing mill, the sound intensity of the pulverizing mill and the mill output or fuel demand signal.
