ABSTRACT:
Apparatus for feeding fluidized particulate material at a uniform preselected flow rate includes a reservoir for receiving the material from a supply inlet, a device for maintaining material in the reservoir in a state of flux, a chain type carrier for continuously removing and transporting uniform quantities of the fluidized material at variable speed from the reservoir along a predetermined path configured to prevent premature discharge of the uniform quantities, and a control system to detect the quantities of material being transported along the predetermined path to regulate the speed of the carrier according to the desired preselected flow rate, such that the fluid particulate material is discharged at the desired flow rate at the end of the predetermined path.
