Estimation of various wet crushing methods for construction wastes recycling

Abstract

The three kinds of wet crushing methods are used for the liberation of construction wastes in recycling. One crushing method is a underwater explosion, the second is an electro disintegration in water and the third is a compression mechanical crushing. The explosion crushing underwater has shown effective liberation for composites that is difficult to separate by normal mechanical crushing in construction wastes. The electric crushing in water is possible to separate concrete and iron in more than 50kV. The explosion underwater crushing needs smaller energy by comparing normal mechanical crushing for liberation between concrete and iron.
