SCIENCE & TECHNOLOGY: The improvement of roller mills

摘要

Rollers are the key components of roller mills. The manufacturing quality and precision of the rollers decides the flour quality and, therefore, the success of the mill as a whole. China's roll production, after half a century of development, and theefforts of several generations, is constantly improving in terms of technical level and equipment. Successively the chill cast iron, the centrifugal casting process to produce high quality roll, has been upgraded repeatedly. Especially, since the turn ofthe new century, the main productionfactory has switched to electric furnaces and improved formulae, rapidly improving the quality of products.
