As vital conveying equipment for grain and feed processing, screw conveyors feature compact structure, fully enclosed dust-free design, stable operation and wide adaptability. They run through the whole workflow including grain receiving, processing and storage, as well as feed raw material handling, pelleting and finished product transportation, serving as indispensable core machinery for intelligent and clean production in the industry.
In the grain sector, screw conveyors are applied across the entire industrial chain. During grain procurement, mobile screw conveyors flexibly load, unload and transfer grains between trucks and silos, greatly cutting manual labor. For storage, the fully enclosed structure blocks dust and moisture, preventing raw grains such as wheat, corn and rice from mildewing while avoiding contamination by rodents and pests to secure grain storage safety. On grain processing production lines, screw conveyors quantitatively feed raw materials to cleaning sieves, destoners and milling machines. The tubular sealed structure stops grain dust leakage and improves the workshop environment. Special models for drying sections adapt to high-temperature working conditions, and the low-speed conveying design significantly reduces grain breakage to preserve intact grain quality.
Screw conveyors act as critical links throughout feed production. Powdery and granular feed materials including corn flour, soybean meal and bran are automatically conveyed from silos to crushers and mixers via screw conveyors. The feeding speed can be precisely controlled to meet accurate formula proportioning requirements. Mild mixing occurs during transportation to homogenize raw materials. In the pelleting process, the equipment smoothly delivers mixed materials to pellet mills, then transports formed pellets to coolers and grading sieves. Low rotating speed minimizes pellet breakage loss. At the finished product stage, screw conveyors directly transport materials to packaging sections. Sealed delivery prevents feed from absorbing moisture and caking, maintaining stable quality of finished feed.
To meet sanitation and working condition requirements of grain and feed production, screw conveyors can be manufactured with 304 stainless steel. The smooth inner surface leaves no material residue, facilitating cleaning and disinfection and complying with food and feed safety production standards. Shafted and shaftless models suit dry materials, wet materials and sticky materials respectively. They can be installed horizontally or at various inclined angles to fit compact factory layouts.
Nowadays, the grain and feed industry is advancing toward large-scale, eco-friendly and automated production. With low energy consumption, easy maintenance and zero pollution, screw conveyors have become standard equipment in the sector, laying a solid mechanical foundation for efficient and green industrial development.
