Currently, most suction feeders on the market operate intermittently, with adjustable feeding and discharging times and controllable conveying capacities. So, how can they be adjusted to maintain a continuous feeding state? Below, we provide answers to this question.

Add Another Suction Feeder of the Same Model
The principle of this method is to allow two suction feeders to complement each other—one performs suction and storage, while the other discharges material. This cycle repeats, ensuring that suction and discharging proceed continuously.

Add a “Buffer Hopper” Equipped with a “Level Sensor”
The principle of this method is that the buffer hopper can continuously supply material to the receiving equipment. When the buffer material level reaches the upper level sensor, a signal is sent to stop the suction feeder from feeding. When the buffer material level drops to the lower level sensor, a signal is triggered to restart the suction feeder for feeding.

Replace the Discharge Valve of the Suction Feeder with a Rotary Valve
The rotary valve rotates continuously, maintaining the vacuum inside the suction feeder’s hopper while simultaneously carrying material to the discharge port. This enables the suction feeder to achieve both continuous suction and continuous discharging.
