Rotary Sifter

A rotary sifter, also known as a rotary sieve or centrifugal sifter, is a specialized screening device used in various industries for the separation and classification of dry bulk materials. It operates on the principle of centrifugal force to efficiently sift and classify particles based on size, shape, and density.

The rotary sifter consists of a cylindrical screen or sieve basket mounted on a central shaft. As the shaft rotates, the centrifugal force generated by the spinning motion causes the material fed into the sifter to move radially outward and come into contact with the screen surface. The material passes through the screen openings, while oversized particles are retained and discharged separately.

One of the primary functions of a rotary sifter is to efficiently remove oversized or undersized particles from bulk materials, ensuring product quality and consistency. It effectively separates fines, agglomerates, and foreign contaminants from powders and granules in industries such as food processing, pharmaceuticals, chemicals, and minerals.

Rotary sifters are designed to handle a wide range of materials, including powders, granules, pellets, and aggregates. They are commonly used for screening applications such as scalping, dedusting, and grading, where precise particle size control is essential for product quality and process efficiency.

One of the key advantages of rotary sifters is their high throughput capacity and efficiency. They can process large volumes of material in a relatively short time, making them suitable for high-volume production environments. Additionally, rotary sifters are versatile and can be customized with different screen configurations, mesh sizes, and surface treatments to meet specific application requirements.

Overall, rotary sifters are indispensable screening solutions that offer efficient and reliable particle size classification in various industries. Their ability to remove oversized contaminants and ensure product consistency makes them essential equipment for manufacturers seeking to optimize production processes and meet quality standards.
