摘要： A flow control system in a tobacco shredding machine or the like having a conveyor means for conveying raw material under compression up to a shredding port and a rotary drum cutter adapted to rotate in close proximity to the shredding port and shred the raw material forced out from the shredding port. A rotational torque of the rotary drum cutter is detected by a torque detecting means and the number of revolutions of the same cutter is detected by a number-of-revolutions detecting means, then on the basis of the detected rotational torque and number of revolutions the number of revolutions of the rotary drum cutter is controlled so as to give a target flow rate of raw material by a number-of-revolutions control means, and the conveyance speed of the conveyor means is controlled in synchronism with the rotary drum cutter by a speed control means. The flow rate of raw material can be maintained constant and the quality of shredded pieces is stable. There is no problem of the increase of cost nor is there an increase of the installation space.
