Mini-Mill in the Alp

Mini-Mill in the Alp

Mini-mills are commercialised by Belfast Mini-Mill and manufactured in US/Canada.
The machinery enables the processing of raw animal fibers or man-made fibers into yarn.
The Belfast Mini Mill is capable of processing small batches down to ounces or grams in size or large commercial size batches of tons. Although the individual machines are small, relative to a large commercial mill, they have been designed to be modular.
In Cernier, Laines d'Ici have a complete mini-mill allowing them to process sorted raw wool into yarns.
