Selective Comminution of Concrete Waste and Recovery of the Concrete Constituents in a Grinding-Drying Process

Using a Loesche VRM, trials were carried out in order to determine the extent to which the constituents of concrete waste could be made suitable by a special recycling process for use as a substitute for the natural rock fraction in components. In this process, the employment of suitable separation equipment played a crucial role.

This article describes a new process for the separate recovery of the components of concrete waste by means of selective comminution in combination with dry separation by density.
