IMPROVING THE QUALITY OF OPERATION OF A MOBILE CRUSHER IN A BUNKER FOR STORING SOLID MATERIALS

Abstract

In the context of increasing industrial production and growing demands for the quality of bulk material storage, improving unloading and cleaning technologies of storage bunkers has become highly relevant. Traditional methods of removing cohesive or non-free-flowing materials often fail to ensure complete discharge and require considerable time and labor. This study focuses on the development and justification of a portable vault-breaking device designed for the efficient destruction of material blockages and agglomerates in bulk storage containers. The main objective of the research is to create a rational and universal design of a portable device that provides optimal unloading conditions for various materials, taking into account their physical and mechanical properties. The study tasks included analyzing existing technologies, selecting the most effective working tools, conducting experimental tests, and developing recommendations for design optimization. As a result, a technological process for operating the mobile device has been developed, ensuring complete container unloading and simultaneous cleaning of its walls from residual materials. The optimal parameters of working elements (length, cross-section shape), the number and placement of technological openings in the bunker walls, and suitable materials using both traditional and additive manufacturing methods have been determined. The findings confirm that the implementation of the developed mobile device significantly increases process efficiency, reduces downtime, and lowers maintenance costs. The obtained experimental relationships and theoretical results can serve as a foundation for future research aimed at automation and digital modeling of the vault-breaking process.
