Performing Final Discharge
Chapter
4
Final discharge control is a procedure to control discharge of raw material for each final from tanks
such as hoppers. A constant amount can be accurately discharged by appropriately combining control
settings such as final/set point 2/set point 1/compensation, judging settings such as over/under/go and
timer settings such as comparison inhibit/judging and so on.
For discharge procedures, ther
e are feed weighing and discharge weighing, and for control procedures,
there are simple comparison control and sequence control.
