In simple terms: a double destoner machine with a vibratory feeder controller is a smart, industrial-grade solution that removes stones and heavy impurities from grains with high precision and consistency. It is designed for real-world mill conditions, where uniform feeding, reliability, and efficiency matter more than theory. In today’s grain-processing plants, this combination has become a practical necessity rather than a luxury.

What Is a Double Destoner Machine with Vibratory Feeder Controller?
A double destoner machine is an advanced grain-cleaning unit that removes heavy contaminants such as stones, mud balls, and metal fragments from rice, wheat, pulses, and other grains. When paired with a vibratory feeder controller, the machine achieves uniform, controlled feeding—crucial for maintaining consistent separation efficiency.
At Kathir Sudhir Automation India Pvt Ltd, the vibratory feeder controller is specially designed to integrate with double destoner machines, ensuring stable operation even with non-free-flowing materials.
Key Aspects
- Cleaning Principle: Gravity separation + vibration

- Industries: Rice mills, flour mills, pulse processing, seed plants
Key Features and Technology
- Double-Deck Structure: Improves separation accuracy and throughput
- Vibratory Feeder Controller: Maintains uniform material flow without compaction
- Adjustable Parameters: Feed rate, deck inclination, and air volume
- Construction: Stainless steel (SS) or mild steel (MS) options
- Motor Power: Typically 1 HP to 5 HP (or higher for large capacities)
Comparison Table: Manual Feeding vs Vibratory Feeder Controller
| Aspect | Manual / Basic Feeding | Vibratory Feeder Controller |
|---|---|---|
| Feed Uniformity | Inconsistent | Highly uniform |
| Stone Removal Efficiency | Moderate | 98–99% |
| Material Flow | Can choke or surge | Smooth & controlled |
| Operator Dependency | High | Low |
| Long-Term Stability | Variable | Excellent |
How It Is Used (Practical Flow)
- Raw grain enters the vibratory Controller
- Controller regulates amplitude and feed rate
- Grain spreads evenly on the destoner deck
- Heavy impurities move in the opposite direction
- Clean grain exits separately with minimal loss
Steps to Follow (Installation & Operation)
- Level the machine and ensure proper deck inclination
- Connect and calibrate the vibratory feeder controller
- Adjust air flow based on grain type
- Start with low feed rate, then optimize
- Monitor output and fine-tune settings
