Gravity Separator introduction
The gravity separator is a device that sorts materials by utilizing the difference in specific gravity between the granular material and its impurities..It efficiently removes blighted seed, budding seed, damaged seed,injured seed, rotten seed, deteriorated seed, moldy seed, non-viable seed, from legumes, grains, and seeds, and is widely utilized in the processing of grains, legumes, and seeds.
Machine Grain Flow Chart

During operation, the material is primarily subjected to two forces: airflow and vibratory friction. Under the influence of the airflow, the material enters a state of suspension; simultaneously, the vibratory friction causes the suspended material to stratify, with lighter particles rising to the top and heavier particles settling at the bottom. Finally, the vibration of the specific gravity table causes the lighter impurities in the upper layer to flow downward, while the heavier finished product in the lower layer moves upward, thereby completing the separation of the material from the impurities.
What gravity separator can do?
The gravity separator is to produce proportion segregation phenomenon under stress of aerodynamic and vibration friction of graininess material .Separates materials of identical size but differing specific gravity, and removes immature and insect-damaged particles.Suitable for cleaning and processing plants handling sesame, soybeans, mung beans, kidney beans, chickpeas, coffee beans, and peanuts.

lading picture for different clients
Hebei Taobo Machinery is a leading Chinese supplier and manufacturer of gravity separators.Taobo 5TBG-8 gravity separator utilizes the combined action of an upward low-pressure airflow and an inclined, reciprocating vibrating screen to sort materials based on density differences:
Intact soybean kernels have a lower density, whereas contaminants such as mud clods, soil aggregates, stones, moldy or damaged beans, and stones of similar size to the beans have higher densities. As the airflow passes through the screen, it gently lifts the soybeans to form a loose, combined with the screen's small-amplitude reciprocating vibration, the materials automatically stratify by weight, effectively separating impurities from good beans. The process involves no intense friction, resulting in a low breakage rate.
Taobo gravity separator is the best machine for cleaning soybeans.It is suitable for processing a wide range of crops, including wheat, corn, mung beans, coffee beans, kidney beans, sesame seeds, chickpeas, and pigeon peas, as well as other granular materials requiring high purity and uniform density.
The production capacity of the Gravity Separator varies depending on the model. Generally, it is 5 to 8 tons per hour, which depends on the type of materials and impurity levels.Gravity separators for beans with capacities of 5 TPH and 8 TPH are available.
As a leading enterprise in the domestic grain and seed cleaning equipment industry, Hebei Taobo Machinery is a top-tier manufacturer and global supplier of gravity separators, possessing independent export qualifications and advanced technical capabilities. The company operates a large, self-owned production facility spanning 6,000 square meters and holds 10 patents, offering customized solutions and complete production line setups. Thanks to exceptional product quality, reliable supply capabilities, and a comprehensive after-sales service system, our equipment is exported to grain, oil, and legume processing enterprises worldwide.

2026 gravity separator utilizes differences in material specific gravity to perform sorting. It is specifically designed to remove impurities and inferior-quality grains that are similar in size to the target seeds—particles that are otherwise difficult to separate using conventional air-screen or vibrating-screen cleaners. It serves as a core piece of precision-sorting equipment in processing lines for grains, sesame seeds, and legumes.

Sesame seeds are extremely small (approximately 1.5–2 mm in diameter) and flat-oval in shape, with a smooth surface, high oil content, and relatively low specific gravity. These physical characteristics present unique challenges for cleaning: while light impurities—such as stalks, husks, dust, and shriveled or empty seeds—can be removed via air classification (aspiration), and oversized or undersized debris can be intercepted through screening, certain contaminants pose a greater difficulty. Specifically, stones, sand, clods of soil, and metal fragments—which are similar in size to sesame seeds but have a significantly higher specific gravity—cannot be effectively separated by either air classification (as they are too heavy to be moved by airflow) or screening (as they pass through or are retained alongside the seeds).

Pakistan is a significant global producer and exporter of sesame seeds, ranking as one of the few oilseed crops for which the country maintains a net export position. According to data from Pakistan’s Ministry of National Food Security and Research, the area under sesame cultivation expanded substantially from approximately 259,900 hectares in the 2022/23 crop year to about 399,800 hectares in 2023/24—an increase of 53%. Production reached approximately 301,200 tonnes, a sharp year-on-year rise of 97.7%. For the 2024/25 crop year, production is projected to climb further to approximately 440,000 tonnes (a 44.7% year-on-year increase), with the harvested area—as recorded by FAOSTAT—exceeding 700,000 hectares. The primary production regions are concentrated in Punjab province (cultivated during the *Kharif* monsoon season, covering approximately 1.76 million acres in 2024) and parts of Sindh province. In recent years, technical cooperation between Pakistan and China, alongside the adoption of contract farming, has led to significant improvements in both crop yields and the level of commercialization.
