Apparent dynamic coefficient of friction of corn on galvanized steel bin wall material

Tests were conducted to study sources of variation in the dynamic coefficient of friction of corn on galvanized steel. The factors analyzed were grain moisture content, grain pressure, and number of trials. The coefficient of friction was statistically significantly lower for 12% (w.b.) moisture content corn than for 16% (w.b.) moisture content corn. The coefficient of friction decreased with repeated sliding contact between metal and grain for all pressures and moisture contents. No significant influence of pressure on the dynamic coefficient of friction was seen.
