The greases are made by premixing all ingredients at 250 to 300F with a propeller stirrer and then milling on a three-roll mill. Greases are usually given two passes through the mill---the first a quick "open" pass and the second at a tight setting. In both passes, the clearance between the last two rolls is set at 0.001 in. To prevent moisture condensing on the rolls and introducing water into the greases, hot water at 140F is circulated through the rolls. Most of the work is performed with a highly refined paraffinic oil with a viscosity of 2000 SSU at 100F and a viscosity index of 100. |
