Short dump belt conveyors are used to create bulk cargo both as an integral part of technological machines in the processing of building materials, and as vehicles in a chain of conveyors for transporting bulk cargo in accordance with the logistics of open warehouses. When implementing mechanization schemes for open warehouses, depending on the degree of variability of the cargo flow in the structures of such conveyors, drives can be used that allow regulating the speed of the belts, thereby controlling the productivity of the entire line. Often, short belt conveyors are not equipped with specialized unloading devices, which requires elaboration of the issues of movement of cargo particles during unloading, especially if the conveyor is operating in a production line. The article simulates the processes of unloading short dump belt conveyors when controlling the speed of the belt. Trajectories of movement of cargo particles for various parameters of conveyors are obtained: belt speed, conveyor tilt angle to the horizon, diameter of the unloading drum. It is shown that it is necessary to simulate unloading processes in all cases with belt speed control and conveyor operation without specialized unloading devices.
