The vibrating grading screen features high screening efficiency, large processing capacity, simple structure, and easy maintenance. Its vibration trajectory is a continuous elliptical or linear shape, effectively promoting material flow and stratification on the screen surface, preventing screen blinding. The cleaning device (such as bouncing balls) continuously cleans the screen mesh, keeping the apertures clear. The fully enclosed structure prevents dust emission, improving the working environment. By changing screens with different mesh sizes, various grading requirements can be easily achieved, offering great operational flexibility.

Specifications are indicated by screen width and the number of decks, such as the SFJH series. Screen sizes range from 1 square meter to 5 square meters. Power consumption is low, with vibration motor power typically between 0.75kW and 5.5kW. Depending on the screen configuration, it can simultaneously separate oversized impurities, qualified products, and overly fine powder. Processing capacity varies with material characteristics and grading precision requirements, generally from 1 to 8 tons per hour. The parts contacting the material can be made of stainless steel to meet higher hygiene standards.

Has two main applications in feed mills: First, as a preliminary cleaner installed after the receiving pit to remove large impurities (like strings, corn cobs) and fine impurities (like sand, dust) from raw materials (like corn, wheat). Second, as a finished product inspection screen after pellet cooling or crumbling, screening out oversized pellets and excess powder to ensure the consistency and quality of the final product.
