From grain to feed

Extrusion & expanding

Feed manufacturers need extrusion and expansion systems that improve nutrient digestibility, increase safety (by killing pathogens), and alter the physical properties of the feed in the most efficient way possible. Our single-screw solutions (designed by ALMEX) deliver all this and more thanks to a robust, yet basically simple design which guarantees years of trouble-free performance. Used worldwide in everything from animal feed and fish feed to pet food and chemical industries, our extruders and expanders do it all.
