The high performance NFS550 is designed to work after a primary crusher or on its own as a frontline tracked mobile screening machine. NFS550 inclined screen is widely used in quarry, mine construction, waste of demolished building, surface soil, materials recycling, and screening of gravel, coal mine and aggregates. The plant has the capacity to process at a rate 500 t/h and can be fed either by a tracked mobile crusher or an excavator.
