Abstract

The dry grinding of pectins from various sources in a ball mill caused depolymerisation of the pectin molecules as evidenced by the fall in the value of viscosity of aqueous solutions of the pectin and of acetone solutions of the nitro‐ester. The depolymerisation was accompanied by loss of gelling power. The calcium pectate and saponification values were not changed significantly by grinding.

This paper is the second of three parts which describe the analysis and simulation of the grinding process. Generation of the workpiece surface depends on the interactions between the grains of the wheel and the workpiece. The grinding wheel surface generated by dressing was simulated by the method
