Pellet mill

More than half a century’s experience in the field of granulation of products with a reputation for being difficult to process such as alfalfa, straw and sugar beet pulp. An experience and know-how which today allow Promill Stolz to dominate the emerging markets with a high potential, such as wood, energy and the Pelleting of by-products from the production of bio-fuel. In order to fully meet the needs of the market, Promill Stolz has launched a new range of pellet mills called ALLIANCE – a direct descendant of the EVOLUTION pellet mill, which has played a large part in building Promill...
