Abstract: An auger for a grinder material for a tire filling machine, having: a cylindrical column; and a plurality of flights extending outwardly from the cylindrical core, wherein (i) the flights are arranged in pairs extending radially outwards from the cylindrical column at 180 degrees to one another, and (ii) each flight has a sharpened leading edge. Each pair of flights are positioned at angles of approximately 50 or 60 degrees to one another, and each flight extends approximately half way around the circumference of the cylindrical column, and there are no outer edge notches in the flights.

Abstract: A method of controlling operation of a tire filling mixing machine, by: (a) mixing a rubber/polyurethane and a catalyst in a first mixer to form a virgin polyurethane; (b) grinding cured polyurethane core bits in a grinder; (c) mixing the virgin material and the ground material in a second mixer thereby forming a mixed flatproofing material; (d) injecting the mixed flatproofing material into a tire; (e) measuring the ratio of ground material to virgin material in the mixed flatproofing material; (f) comparing the measured ratio of ground material to virgin material to a pre-stored preferred ratio of ground material to virgin material; and (g) increasing or decreasing the relative percentages of virgin material and ground material entering the second mixer by an amount that is a fraction of the difference between the measured ratio and the pre-stored preferred ratio.
