Spirals

Mille Srl is able to produce multiple types of spirals that can be made from different materials.
Constant thickness flat spirals are ideal for shaftless screw conveyors. Cold-stamped sector spirals are particularly wear-resistant. The sectors of the stamped spiral can be made by plasma or laser cutting of different materials: hardened steel, stainless steel, iron, or wear-resistant material such as hardox or creusabro.
