In recent years, research has been underway to create working bodies of excavation machines that allow digging soil at higher speeds. One of these new types of machines are excavation and transport machines with an inertial bottom discharge rotor. The paper presents the results of studies of high-speed digging and proposes a method for determining the average values of the energy intensity of soil transportation, and the proposed equations can be recommended for calculating the inertial rotor. The table of costs of specific energy consumption and productivity from the speed of rotation of the rotor at constant chip sizes is given. The analysis of studies showed that the energy intensity increases with an increase in the speed of rotation of the rotor, and the productivity grows according to a linear law. The inertial-type rotor during the test proved to be quite efficient, and the performance of the tested rotor is four times higher than that of the existing gravity-type rotor.
