The Machinery TQSF Gravity Grader & Destoner is designed to efficiently remove stones, heavy impurities, and light impurities from free-flowing grains and seeds. With its advanced technology, this machine ensures optimal quality and purity of the grain flow by using density-based separation.
Key Features
Working Principle
This gravity grader & destoner is a highly effective solution for maintaining grain quality and removing undesirable impurities, making it a valuable tool for grain processing operations.



| Functionality | Removes stones and heavy impurities from granular grains based on density, and uses air cleaning to eliminate lighter impurities such as dust, grass seeds, and soil. |
|---|---|
| Wide Application | Suitable for free-flowing grains and seeds, particularly for wheat. |
| High Capacity | Available in various models with capacities ranging from 1 to 22 tons per hour, depending on the grain type (e.g., wheat). |
| Efficient Air Cleaning | Machines with an air system effectively remove light impurities such as dust and small particles. |
| Material Flow | Grains fall into the feed box through the inlet, where they are evenly distributed across the screen's width due to machine vibration. |
| Stratification | The upper sieve surface naturally stratifies materials based on specific gravity and particle size, assisted by vibration and airflow. |
| Heavy Impurity Removal | Heavy materials, like stones and clay, fall to the lower sieve, while lighter impurities like hulls and dust are drawn away by suction vents. |
| Efficient Separation | The machine efficiently separates sand, stones, and other heavier debris, discharging them from the machine, while the purified grain flows out. |
The main function of this machine is to efficiently remove stones, heavy impurities, and light impurities from free-flowing grains and seeds, ensuring optimal quality and purity through density-based separation.
This machine is particularly suitable for free-flowing grains and seeds, especially wheat, but can also work with other similar grains.
The machine is available in various models with capacities ranging from 1 to 22 tons per hour, depending on the type of grain being processed.
The air cleaning system effectively removes light impurities such as dust, grass seeds, and small particles by using suction vents that draw these impurities away from the grain flow.
Grains fall into the feed box, where they are evenly distributed across the screen. The upper sieve surface stratifies materials based on specific gravity and particle size, allowing heavy impurities to fall to the lower sieve while lighter impurities are drawn away by airflow.
Yes, the machine is designed to remove both heavy impurities like stones and clay, as well as lighter impurities such as dust and hulls through its effective air cleaning and gravity separation methods.
Yes, the Wheat Seeds Destoner is designed for ease of use, with simple controls and an intuitive setup to maximize efficiency in grain processing.
Regular maintenance includes cleaning the air system, checking the screens for wear, and ensuring that the vibration and airflow mechanisms are functioning properly.
Using this machine ensures high purity and quality of the grain by effectively removing undesirable impurities, which can enhance the overall value of the processed grains.
Yes, the design of the machine focuses on energy efficiency while maintaining high performance, making it a cost-effective option for grain processing operations.
The warranty period varies by manufacturer, but typically, you can expect a warranty ranging from 1 to 2 years depending on the terms provided at the time of purchase.
Yes, most manufacturers provide technical support and assistance for installation, operation, and maintenance of the Wheat Seeds Destoner.
Yes, the machine can often be customized to accommodate specific grain types or processing needs, depending on the manufacturer's options.
Safety features typically include emergency stop buttons, protective covers, and safety interlocks to ensure safe operation during use.
The Wheat Seeds Destoner offers significantly higher efficiency and consistency in cleaning compared to manual methods, which can be labor-intensive and less effective.
