Gravity Destoner
The suction type gravity destoner removes stones and heavy impurities the same size as the grain, in grain processing plants and rice mills.
What This Machine Does
The suction type gravity destoner removes stones and heavy impurities the same size as the grain, in grain processing plants and rice mills. It is the machine that protects the rubber rollers and the emery in everything downstream of it.
Key Benefits
- Removes grain sized stones that a sieve cannot separate by size
- Dual vibrating motors give stable running with a small footprint
- Double deck stone removing construction for high separation efficiency
- Fully closed construction so no dust spreads into the plant
- Air pressure and air volume adjustable for the crop being processed
Problems It Solves
- Stones the same size as the grain pass every sieve in the plant
- Rubber roller and emery life cut short by heavy impurities
- Stones reaching the buyer and triggering a claim
- Dust spreading from open cleaning equipment
Who It Is For
- Rice mills protecting husker rollers
- Grain processing plants cleaning mixed crops
- Oilseed and peanut processors
- Plants under buyer pressure on foreign matter
Application Scenarios
- Destoning paddy before the husker
- Cleaning wheat, soybean, rapeseed and peanut in grain processing plants
- Protecting rubber rollers and emery rollers from stone damage
- Final cleaning before milling or packing
Technical Features
- Suction type gravity separation driven by vibrating motors
- Vibrating force, direction and sieve cover inclination all adjustable
- Double deck stone removing construction
- Fully closed construction with no dust spread
- Large processing capacity with low power consumption and low noise
Gravity Destoner Model Table
Figures below are taken from the TITAN model sheets. Where a figure depends on the crop or the contamination level it is stated that way rather than averaged.
| Model | Capacity | Power | Air volume | Weight |
|---|---|---|---|---|
| TTDS 85B | 3.5 to 4.5 t/h | 0.75 kW | 3200 to 3400 m3/h | 340 kg |
| TTDS 100B | 5 to 6.5 t/h | 0.75 kW | 3800 to 4100 m3/h | 380 kg |
| TTDS 125A | 7 to 8.5 t/h | 1.1 kW | 4800 to 5200 m3/h | 400 kg |
| TTDS 168 | 10 to 12 t/h | 1.5 kW | 7500 to 7800 m3/h | 510 kg |
| TTDS 170 | 10 to 12 t/h | 13 kW | 9000 to 10800 m3/h | 850 kg |
| TTDS 200 | 13 to 15 t/h | 15 kW | 9000 to 10800 m3/h | 890 kg |
How This Machine Is Built
Quality Control
- Inner resistance checked at 40 to 50 mm water column on the B and A frames
- Vibration balance verified on the assembled machine
- Sealing checked so the closed construction holds dust in
Materials And Wear Parts
- Rubber mounts on the vibrating assembly
Customisation Options
- Model chosen from the throughput of the line
- Deck inclination and air settings adjusted per crop
- Single or double layer suction type versions
Use Guide
- Install ahead of the husker, not after it
- Adjust air volume and deck inclination when the crop changes
- Check the stone outlet regularly so it does not block
- Keep the machine closed during operation to hold dust in
How It Compares With The Alternatives
| Sieve cleaning alone | Separates by density, so it catches stones that are the same size as the grain. |
|---|---|
| Manual picking | Continuous separation at up to 15 t/h instead of a spot check on a moving stream. |
Gravity Destoner Questions
Which crops can it handle?
Wheat, paddy, soybean, rapeseed and peanut in grain processing plants, and rice in rice milling plants.
How is separation adjusted?
Vibrating force, vibrating direction and the inclination of the sieve cover are adjusted to the specific requirement, together with air pressure and air volume.
What capacity range is available?
From 3.5 to 4.5 t/h on the TTDS 85B up to 13 to 15 t/h on the TTDS 200.
Does it need aspiration?
Yes. Air volume figures from 3200 m3/h to 10800 m3/h are listed per model.
Will it damage the grain?
Separation is by density on a vibrating deck, so the grain is not milled or abraded in this stage.
