In order to further promote the processing and reuse of tailings waste rock resources, the Chinese government has successively introduced relevant supportive policies to encourage the use of waste rock and the tailings of iron, molybdenum, vanadium and titanium mines to produce mechanism stone. By 2025, the proportion of sand and gravel produced using tailings, waste rock, construction waste will increase significantly, with output accounting for 30%.

In mine tailings and waste rock processing mechanism sand and gravel projects, crushers, sand making machines, vibrating screens and other equipment are all direct processing equipment. The performance of the equipment will directly affect the quality of the mechanism sand.

As a domestic large-scale mine crushing, grinding and sand-making equipment production base, Kefid developed jaw crushers, cone crushers, impact crushers, sand making machines, VU floor sand-making systems, mobile crushers and other series of sand and gravel processing equipment have been widely used in many foreign and domestic ore and rock processing sand and gravel production projects, as well as tailings, waste rock, construction waste sand and gravel processing projects.

Practice has proved that the mechanism sand processed from mine tailings and waste rock can be used as building ballasts, building sands, etc., for road filling, brick making, or concrete preparation below C30. At present, there have been many application results. If the quality of tailings and waste rock raw materials is high enough, it can also be used for the preparation of higher-grade concrete such as C40-C60.

We have accumulated rich experience and strong technical and equipment support in the sand and gravel projects of construction waste processing such as tailings and waste rocks. Welcome consulting and exchange of related technologies and processing equipment.
