Rotary Vibrating Screen Used to Remove Impurities of Different Diameters From Corn Starch

The starch rotary vibrating screen is a high-efficiency screening device specifically designed for the starch industry, aimed at grading, impurity removal, and cleaning of starch to achieve fine separation, while improving screening efficiency and ensuring product quality. Through the rotational motion generated by the vibrating motor, this equipment can quickly separate starch of different particle sizes, ensuring product uniformity and quality. Its multi-layer screen design makes the screening process flexible and convenient, while its good sealing and low noise characteristics also meet environmental protection requirements, widely used in the production of corn starch, potato starch, etc., significantly improving the purity and production efficiency of starch.

Working Principle

The rotary vibration screen generates rotational vibrations through a vibrating motor, causing the material to continuously move on the surface of the screen. Under the action of vibration, larger particles are retained on the upper screen, while smaller particles fall through the screen openings to the lower layer. Through the grading and screening of multi-layer screens, the rotary vibrating screen can efficiently and accurately achieve the separation and classification of materials, while some models also feature an automatic cleaning function to prevent screen blockage and maintain screening efficiency.

Features

Improve screening accuracy. Effectively remove impurities and dust from starch, achieving fine separation and thereby enhancing starch quality.
Increase production efficiency. The efficient screening capability significantly enhances the screening efficiency of starch, accelerates production speed, and reduces production costs.
Reduce manual intervention. Intelligent operation and automatic cleaning functions reduce manual intervention and maintenance time, lowering operating costs.
Fully sealed design. Ensures no dust pollution, no liquid leakage, no residue inside the machine, and no dead corners in the screen frame.
