Abstract
Increasing the flow rates of the main work processes is one of the promising ways to achieve the highest productivity of earthmoving machines. In this regard, the requirements of increasing the maneuverability and mobility of these machines while simultaneously increasing output, reducing their weight, and specific energy consumption of work processes leads to the widespread use of continuous transport with rotary machines of layered development. One of these new types of machines are excavating and transport machines with an inertial rotor of lower unloading, which can be widely used when performing large volumes of excavation, stripping and mining operations in the mining, reclamation and construction industries. The paper presents the results of studies of high-speed digging and suggests a method for determining the average energy intensity of soil transportation, and the proposed equations can be recommended for calculating the inertial rotor. The table of costs of specific energy intensity and productivity from the speed of rotation of the rotor at constant chip sizes is given.
