The large-scale development of the grain industry has placed higher demands on the screening accuracy and processing efficiency of grains, legumes, and cereals. Traditional screening methods are not only inefficient but also difficult to accurately grade grains of varying sizes and qualities, resulting in inconsistent product quality during subsequent processing. Our grading screening machine from Taobo utilizes advanced technology to address these challenges.
This grading machine utilizes unique vibration screening technology. By precisely controlling the vibration frequency and amplitude, it ensures that grains, legumes, and cereals are evenly distributed and quickly screened. The multi-layered screen design with varying apertures allows for simultaneous, multi-dimensional grading of grains, efficiently separating large impurities such as straw and rocks, as well as fine dust and grains. For example, in soybean screening, the equipment accurately distinguishes soybeans of varying particle sizes, resulting in a uniform product size, significantly enhancing the product’s market competitiveness.
After the equipment starts up, the “power system” provides energy for overall operation. The equipment then enters the screening area to prevent local accumulation that affects the grading effect. This is the foundation for subsequent separation.
Power Drive Mechanism
The core power source of the grading screen is a vibrating motor (for small and medium-sized equipment) or an eccentric shaft combined with a conventional motor (for large equipment):
Vibrating motor: Eccentric blocks are mounted on both ends of the motor’s output shaft. When powered, the eccentric blocks rotate at high speed, generating periodic centrifugal force that drives the screen body to vibrate in linear, circular, or elliptical trajectories (different trajectories correspond to different screening requirements).
Sieving separation is the most basic and commonly used function of a grading screen. Using screens of varying apertures, the material is sorted into three categories based on particle size: “large particles,” “qualified particles,” and “small particles/impurities.” The principle is similar to “sifting sand through a sieve,” but the mechanical vibration significantly improves efficiency.
Our Tobo grading machine can be used for a wide variety of materials. Leveraging its core advantages of “multi-dimensional separation technology + parameter adjustability,” it can accommodate materials of varying particle sizes, specific gravities, and shapes, including sesame, soybeans, mung beans, soybean beans, coffee beans, chickpeas, and pigeon peas. When selecting equipment, businesses can choose the configuration based on the characteristics of the core materials they process.
