Complex Recycling of Crushed Aggregates Waste

Abstract

The problem of the formation and processing of waste in the production of crushing stone for road construction is considered. An integrated approach is proposed, which implies both a reduction in the amount of waste generated and its subsequent processing to obtain products in demand on the market. The technologies based on the use of vibration equipment and allowing to obtain qualified products from crushing screenings are described: cubical crushed aggregates, high-quality fractionated artificial sand and vibro pressed products based on it. The possible options for recycling the dust-like component of the waste with the production of lightweight aggregate for concrete and mineral wool are given. An estimate of the predicted environmental effect of preventing the disposal of waste from the production of crushing stone for road construction, subject to the application of the proposed technologies, is given.
