Metallurgical slag disintegration in centrifugal impact crushing machines

摘要

In focus are issues of metallurgical slag disintegration in centrifugal impact crushers. The article shows the model of material breaking in the centrifugal impact crusher chamber. The scheme of force interaction between slag particles and the crusher chamber is developed considering spread inertia load. It is found how structural parameters of crushing machines are connected with the process properties of slag, and the velocity and physico-mechanical properties of a slag particle are related. The authors give technological recommendations on adapting centrifugal impact crushing technique to mining waste pretreatment flowcharts.
