Patent ID: 8893993

Claim:
A method comprising the steps of: (A) providing a disc mill assembly comprising: (1) a housing; (2) a flywheel comprising a generally circular disc having first and second sides, wherein the first side has a first relatively inner raised mating member that is raised to a first height and a second relatively outer raised mating member that is raised to a second height, wherein the first height is different than the second height; (3) a water jacket comprising a generally circular disc having first and second sides, wherein the first side has a first relatively inner raised mating member that is raised to a first height and a second relatively outer raised mating member that is raised to a second height, wherein the first height is different than the second height; (4) a first grinding disk comprising a generally circular disc having first and second sides, wherein the second side comprises a cutting surface; (5) a second grinding disk comprising a generally circular disc having first and second sides, wherein the second side comprises a cutting surface; (B) attaching the first side of the first grinding disk to the first side of the flywheel wherein the first side of the first grinding disk contacts the first relatively inner raised mating member and the second relatively outer raised mating member of the first side of the flywheel to thereby deform the shape of the cutting surface of the first grinding disk; (C) attaching the first side of the second grinding disk to the first side of the water jacket wherein the first side of the first grinding disk contacts the first relatively inner raised mating member and the second relatively outer raised mating member of the first side of the water jacket to thereby deform the shape of the cutting surface of the second grinding disk; (D) positioning the flywheel, water jacket, first grinding disk and second grinding disk within the housing wherein: (1) the second side of the flywheel is secured to an associated rotating spindle; (2) the flywheel and the first grinding disk are rotatable within and with respect to the housing; (3) the second side of the water jacket is fixedly secured to the housing; (4) the cutting surfaces of the first and second grinding disks face each other; and, (5) a tapered grinding channel, that is used to grind associated materials when the disc mill assembly is operated, is created between and defined by the cutting surfaces of the first and second grinding disks by the deformation of the first and second grinding disks.
