In modern feed production, the precise dosing of various additives such as vitamins, amino acids, and enzyme preparations directly determines feed quality and animal health. However, most additives feature fine particle sizes, high hygroscopicity, easy caking, and strong corrosiveness, posing severe challenges to screening equipment. Having deeply engaged with frontline feed production, GAOFU Machinery has developed dedicated vibrating screening equipment for feed additives. Through professionally engineered designs, it resolves industry pain points including screen clogging, corrosion, and cross-contamination, helping enterprises achieve accurate dosing and stable production.

I. Professional Design Tailored to Additive Characteristics

Feed additives feature complex compositions, ranging from trace mineral elements to biologically active substances. Equipped with multi-layer precision screens and an adjustable flexible vibration system, GAOFU equipment effectively separates powder and granular materials within the range of 0.074mm to 10mm, enabling precise control over the particle size distribution of additives. Vibration parameters are specially optimized to fully disperse agglomerated materials without damaging active ingredients via excessive vibration, ensuring the screened materials maintain an optimal physical state.

II. Full-Process Anti-Corrosion Treatment

For corrosive additives such as acidifiers and mineral salts, core contact parts of the equipment are made of 304/316L stainless steel, with key components available for special coating treatment. Seals are manufactured from food-grade corrosion-resistant materials. The entire machine delivers excellent rust and corrosion resistance, maintaining stable operation even under long-term contact with various additives and significantly extending service life.

III. Cross-Contamination Free Design

Adopting a fully enclosed structure combined with high-efficiency sealing technology, the equipment completely prevents dust emissions during screening. Its unique quick-disassembly cleaning system allows fast and thorough cleaning when switching additive types, avoiding cross-contamination caused by material residue. This makes it especially suitable for multi-variety, small-batch feed additive production lines.

IV. Intelligent Anti-Clogging and High-Efficiency Operation

In response to the tendency of additives to adhere and clog screens, the machine is fitted with multi-stage screen cleaning devices (bouncing balls or ultrasonic systems optional), realizing continuous self-cleaning of the screen surface. The optimized screen box structure ensures more uniform material distribution, increasing processing capacity by 15%–30% compared with traditional equipment while reducing energy consumption by approximately 20%, truly achieving efficient and energy-saving production.

V. Adaptation to Diverse Production Requirements

The equipment is suitable not only for screening and impurity removal of single additives but also for final screening of premixes and precise classification of micro-ingredients. Its modular design supports customization of screen layers and discharge port configurations, meeting demands ranging from laboratory R&D to large-scale industrial production.

With years of deep expertise in the screening field, GAOFU Machinery has provided professional screening solutions for numerous large feed groups. We deliver not only equipment but also full-process technical services including process analysis, equipment selection, installation, and commissioning, ensuring every unit delivers maximum value in real production.
