Experimental study of the operation of a portable roof breaker to eliminate hanging in a bunker for storing bulk materials

The article presents the results of experimental studies of the operation of a portable arch breaker-cleaner for unloading arch-forming cargo from stationary and mobile bunker devices; the reasons for the emergence of difficulties in the release (unloading) of arch-forming cargoes due to the production technologies used in the industry (storage, transportation, dosing, loading and unloading operations) are analyzed; a technological process for the operation of various mobile devices is being developed in order to optimize the scope of their application based on the designs of storage (transportation) containers, the own design of mobile devices, their operating modes, and the physical and mechanical properties of the working environment; a method for experimental studies of the functioning of laboratory samples of arch breaker devices is offered with the search for an effective combination of factors of their operation: type of cargo, location of technological holes in the walls of an experimental bunker device, dimensions of working bodies, operating modes.
