Machinery TQSF Gravity Grader & Destoner for Grain and Seed Processing

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

• 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.

Working Principle

• 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.

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.
