ROLL MILL DEVICE FOR PASTE PRODUCTION

摘要

PROBLEM TO BE SOLVED: To provide a roll mill for paste production, which enables the break of aggregate by reducing deformation of the surface of a roll and has long service life by the improvement of the wear resistance of the surface of the roll. SOLUTION: The surface of the roll is coated with a sintered hard material such as a tungsten carbide-cobalt based alloy by thermal spraying.
