In the tense situation of global mineral resources, the world's developed countries find that the the residue and tailings left after processing and utilization of mineral resources contain a secondary advantage of business opportunities. China is a major mining country. Therefore, the development and utilization of long-term accumulation of tailings can turn waste into treasure and effectively alleviate the pressure of resources and environment. The tailing is not only the waste discharged by mining companies through certain technical and economical conditions, but also the potential secondary resource. When the technical and economical conditions are allowed, the tailing can be effectively developed again.

At present, for domestic the recycling projects of tailings, Henan Hongxing Mining Machinery absorbs the advanced technology of Europe and combines with the company's advanced design and manufacturing concepts and market demands of tailing recycling. After many years' painstaking design, Henan Hongxing Mining Machinery developed the pleiotropic cone crusher. This new cone crusher can solve the problems of recycling tailings, water granulated slag, residue, coal ash in the large projects. This kind of crusher also solves the technical problems of low yield of tailings recycling and high energy consumption. Hongxing pleiotropic cone crusher absorbs the current advanced crushing technology which has been widely used in recycling steel slag and mineral waste residue. The cone crusher is suitable for crushing all kinds of ore and rock with hardness or medium degree of hardness. 

The pleiotropic cone crusher produced by Henan Hongxing Mining Machinery makes great contribution to the recycling of slag resource.
