Abstract
A method of performing preventative maintenance on an auger in a tire filling mixing machine, by: (a) mixing a polyurethane isocyanate and a catalyst in a first mixer to form a virgin polyurethane; (b) grinding polyurethane core bits in a grinder, the grinder having an auger and a motor; (c) mixing the virgin polyurethane and the ground core bits in a second mixer thereby forming a mixed flatproofing material; (d) injecting the mixed flatproofing material into a tire; (e) measuring vibration of the auger; and (f) comparing the measured vibration of the auger to a predefined maximum vibration; and (g) removing the auger from the grinder if the measured vibration exceeds the pre-defined maximum vibration for a predefined period of time, or removing the auger from the grinder if the measured temperature of the auger exceeds the pre-defined maximum temperature for a predefined period of time.
