Vibration recycling technologies for mining and mineral processing waste for construction purposes

Abstract

The problem of waste generation and recycling in the production of building crushed stone is considered. A comprehensive approach is proposed, involving developing of new technologies based on the application of vibration effects. The main scientific novelty of the solutions consists in the wide use of vibration effects and equipment to solve the most complex technology problems, in the same time with the substantiation of technological conditions and ingredients compositions. The results allow improving the grade of commercial crushed stone, while reducing the output of crushing screenings, and recycling of the screenings with the production of high-grade graded artificial sand and vibration compacted products based on this sand. A technology is developed for utilizing the dust-like component of the waste for the production of mineral wool. The environmental effects from the proposed technological solutions are evaluated.
