Increasing the energy efficiency of production processes is closely related to minimizing
the impact on the environment and is one of the priorities of the concept of sustainable development.
Electric discharge is an effective tool for multilevel grinding of non-metallic materials in various
working fluids and obtaining coarse and fine suspensions. We introduce the technique for calculating
the electrotechnological parameters necessary for energy-efficient electric discharge dispersion. This
technique considers the strength characteristics of the crushed material (dispersed phase) and the
electrical conductivity of the working fluid (dispersed medium). It is also essential to consider the
energy stored in the capacitor bank, the energy criterion, the critical value of the working fluid’s
electrical strength, the radius of the high-voltage electrode point, and the distance from the discharge
channel axis to the disintegration object. All this allows obtaining a given granulometric composition
of the dispersed phase with minimal energy consumption. Experiments confirmed the validity of
the proposed calculation technique. We obtained the water-brown coal suspension with a given
dispersion two times faster and consumed four times less energy in comparison with the known
methods that did not take into account the electrical conductivity of the working liquid and the
mechanical strength of the crushed material.
