RONYI screw refill hoppers sit beside a screw feeder and keep topping it up according to their settings, reducing line stops for refilling. The RY-120 holds 600CC and the RY-140L 800CC, both for M2.0–M6.0 screws (head thickness over 1.0mm, total length under 29mm), with digital settings for the drive motor, detection time and number of refills.
Screw Refill Hoppers That Stretch the Refill Interval
The built-in hopper of a screw feeder has limited capacity, so a continuously running line has to stop every so often to add screws. A screw refill hopper sits beside the feeder and keeps topping it up according to its settings, turning frequent small refills into an occasional bulk load.
RONYI offers two capacities: the RY-120 mid-size hopper holds 600CC and the RY-140L large hopper holds 800CC, both for M2.0~M6.0 screws. The hopper has requirements on screw shape: head thickness must exceed 1.0mm and total length including the head must be under 29mm. Small screws below M2.0 are not suitable for the hopper and should be loaded directly into the feeder.
Digital control lets you set the drive motor, detection time and number of refills, so you can decide how often and how much to refill based on the feeder’s consumption rate. Key parts are CNC-machined and surface-hardened for stable operation over long periods, and the hopper works with a range of feeder models.

Typical Applications
Continuously running automatic tightening lines
The hopper keeps refilling the feeder so the line does not stop when the feeder runs low; manual refilling becomes an occasional bulk load.
High-volume medium and large screws
M2.0~M6.0 screws are bulky, so a feeder holds relatively few of them; these are the screws that benefit most from a refill hopper.
Frequently Asked Questions
When do I need a refill hopper?
When the line runs continuously for long periods, the feeder often runs low, or the screws are large (M2.0~M6.0) so the feeder holds relatively few, a refill hopper is a good fit. It keeps topping up the feeder according to its settings, turning manual refilling into an occasional bulk load.
Which screws can the hopper handle?
Both the RY-120 and RY-140L handle M2.0~M6.0 screws with a head thickness over 1.0mm and a total length including the head under 29mm. Small screws below M2.0 are not suitable for the hopper and should be loaded directly into the feeder.
How do I choose between the RY-120 and RY-140L?
They differ in capacity and size: the RY-120 mid-size hopper holds 600CC, measures L147.4 × W126.8 × H208.5mm and weighs 1.8kg net; the RY-140L large hopper holds 800CC, measures L175 × W163 × H232mm and weighs 3.0kg net. Choose based on the feeder model and screw consumption; we can help confirm the pairing.
Can the refill timing be adjusted?
Yes. The hopper is digitally controlled, with settings for the drive motor, detection time and number of refills, so you can set how often and how much it refills based on the feeder's consumption rate.
