Abstract

Method for breaking down steel slag blocks, which are obtained by the making of iron and steel from ore and which have the form of a hardened mixture of iron and slags, comprising the following steps: - provision of a static collision means, - hoisting of a steel slag block (skull) or portion thereof, - allowing said steel slag block or portion thereof to fall under the influence of gravity onto said collision means, - shattering of at least a part of said steel slag block or portion thereof as a result of the collision forces.
