The gravity destoner machine is designed to remove stones and other heavy impurities from grains before further processing. The TQSX series gravity destoner is suitable for paddy rice, wheat, soybean, groundnut, and other agricultural products, and can remove stones as well as some straw and dust.
Gravity destoners have a capacity of 5-10 t/h. Widely used in flour mills, oil mills, grain processing plants, etc. Using gravity destoners to process grains not only improves the cleanliness of the raw materials but also protects the equipment and extends its service life.
How Does a Gravity Destoner Machine Work?
The gravity stone remover machine works based on the difference in specific gravity between grains and stones. After the grain enters the machine, airflow passes upward through the destoning table while the table vibrates continuously.
The lighter grain particles are fluidized and move toward the clean grain outlet, while heavier stones and other dense impurities remain closer to the table surface and gradually move toward the stone discharge outlet.
Through the combined action of airflow, vibration, and gravity, the machine effectively separates stones from grains, even when they are similar in size. This working principle makes the gravity destoner suitable for cleaning paddy rice, wheat, soybean, groundnut, and other grains before further processing.
What Grains Can a Gravity Destoner Process?
The machine has a relatively wide range of applications in agricultural processing.
- Paddy Rice: In rice mills, stones mixed with paddy can affect rice processing equipment. A gravity destoner machine for rice helps remove these heavy impurities before the paddy enters subsequent processing equipment.
- Wheat: Wheat may contain stones, soil particles, straw, and dust after harvesting. A grain destoner can be incorporated into the wheat cleaning process to improve raw material quality.
- Soybean: For soybean processing, the machine can separate heavy foreign materials from soybeans before further processing.
- Groundnut: Groundnuts can also contain stones and soil picked up during harvesting. A gravity destoner provides an additional cleaning step before subsequent processing.
Where Is a Gravity Destoner Used?
A grain destoner machine can be used in:
- Rice milling plants
- Wheat processing plants
- Grain cleaning plants
- Cereal processing facilities
- Agricultural product processing factories
- Grain storage and preparation facilities
Its role is generally to clean raw materials before they enter important downstream processing equipment.

Can the Gravity Destoner Be Integrated Into an Existing Grain Processing Line?
A grain destoner machine can be used as one stage of a larger grain cleaning or processing system.
A typical rice processing process may include:
Raw Paddy → Cleaning → Destoning → Hulling → Rice Milling → Polishing → Grading
For wheat, the destoner can also be integrated into a cleaning process before grinding.
The exact equipment arrangement depends on the raw material, processing capacity, impurity conditions, and final product requirements.
How Much Does a Gravity Destoner Machine Cost?
The grain gravity destoner price depends on the machine model, processing capacity, configuration, motor requirements, and other project conditions.
For an accurate quotation, buyers should provide:
- Raw material
- Required capacity
- Destination country
- Power supply
- Whether it will be used independently or in a complete processing line
Based on this information, the supplier can recommend the appropriate model and configuration.
Wheat Destoner Machine FAQ
What is a gravity separator destoner?
A gravity destoner machine is grain cleaning equipment used mainly to separate stones and other heavy impurities from grains according to differences in specific gravity.
What materials can the TQSX gravity destoner process?
The TQSX series can process paddy rice, wheat, soybean, groundnut, and other suitable agricultural products.
Can a gravity destoner remove dust?
Yes. The TQSX series can remove part of the dust and straw while separating stones from grain.
Why is a destoner important in a rice mill?
Stones can damage downstream rice processing equipment. A rice destoner machine helps remove these heavy impurities before hulling and milling.
Is the gravity destoner suitable for a complete grain processing line?
Yes. It can serve as a destoning stage within a grain cleaning or processing line, with the configuration selected according to the material and production requirements.
