The Applications of Vibratory Crushers to Improve the Efficiency of Industrial Crushing Lines

Abstract The article presents design solutions of currently used vibratory jaw and cone crushers. These crushers operate based on a different type of load exerted on the crushed material than in presently used crushing machines, namely using rapidly changing multiple impacts of relatively short duration. As a result, they enable achieving more beneficial technological results in higher degrees of fragmentation, higher shares of desired fine grain classes, and lower total energy demand. Due to the above-mentioned properties, they can be a more advantageous alternative to currently used crushing machines. Several studies have confirmed the high technological capabilities of vibratory crushers when crushing materials with different physical and mechanical properties. In particular, when crushing hard and very hard materials (very compact rocks, ceramic materials, ferroalloys), these crushers demonstrate significantly better capabilities than the previously used “classic” crusher designs, i.e. jaw, cone, impact. The research results show the technological possibilities of vibratory crushers when used for crushing limestone, for producing sorbents for flue gas desulfurization, and for crushing sanitary ceramic waste for the production of aggregates for concrete. The possibility of using vibratory crushers in a prototype installation for gold extraction is also described. The advantages of implementing vibratory crushers in industrial crushing technological lines are related to increased efficiency, increased technological possibilities, and the simplification of currently used crushing lines. In most cases, this may result in a reduction of the required crushing stages and, consequently, in the simplification of industrial crushing technological lines, directly reducing the required investment and operating costs.
