Crawl Mobile Impact Crushers

The equipment mainly deals with raw materials such as limestone, construction waste and other materials with low compressive strength. It can be flexibly combined and matched for different purposes, reducing operating costs and improving equipment utilization. In the design process, the dust point is closely linked, and a water mist spray system is set to reduce dust emissions and ensure efficient and environmentally friendly production. Among them, Crawler Impact Crushing Station is divided into NFI1111 and NFI1313 according to the size of the host, and it has equipment with over-recycling crushing function, which are NFI1111RS and NFI1313RS.
