O’Mara 2-Stage Bulk Dribble Gates are engineered to deliver fast, precise flow control in grain handling, seed processing, and bulk material weighing systems. By combining high-speed bulk filling with controlled dribble finishing, these gates help you consistently hit target weights, reduce overfill loss, and improve overall plant efficiency, bag after bag, load after load.
If you are filling open-mouth bags, managing hopper scales, or controlling discharge from augers and blenders, O’Mara bulk dribble gates give you dependable accuracy where it matters most.
A 2-stage bulk dribble gate is a multi-position flow control device used in automatic weighing, bagging, and hopper discharge systems. It regulates how quickly grain or seed leaves the hopper, so your operations are both fast and accurate.
The system works in two simple stages:
This two-speed approach prevents overshooting the target weight while maintaining high throughput.
Think of it like filling a gas tank: you slow down near the end so you can stop at the exact dollar amount.
The slow dribble phase allows weigh controllers and load cells to track weight in real time and stop flow at the exact set-point.
Result: Up to three times less product giveaway compared to single-stage filling.
Bulk bag filling keeps material moving quickly, so production speed stays high without sacrificing precision.
Dual set-points create predictable stopping points every cycle, improving:
Less overfill means:
Heavy-duty slides or pivoting doors move between:
Reliable actuators provide fast, repeatable positioning for accurate transitions between stages.
Weigh controllers use two programmed cutoff points:
Continuous weight monitoring ensures the gate closes at the exact target weight.
Built from abrasion-resistant steel (often 10-gauge or thicker) to handle demanding grain and seed applications.
Ensures fast fills with exact final weights.
Delivers accurate large-volume drafts without slowing throughput.
Provides controlled release for consistent blends.
Fast bulk filling plus controlled dribble finishing balances speed and accuracy.
Tighter weight control protects profit per bag and per load.
Adjustable settings handle:
Engineered for continuous agricultural use in demanding environments.
Designed to fit:
No two facilities handle material the same way. O’Mara designs 2-stage bulk dribble gates to match your exact process.
We evaluate:
The result is a clean installation and dependable long-term performance.
O’Mara equipment is designed by experienced engineers who understand seed plants, grain elevators, and bulk handling systems. Every gate is manufactured with durability, accuracy, and serviceability in mind.
If inconsistent weights, slow bagging speeds, or product loss are limiting your operation, an O’Mara 2-Stage Bulk Dribble Gate can deliver measurable improvement. From concept to fabrication to final assembly, quality is controlled at every step, so your system performs reliably season after season.
