The MAGNA MT620HR is a horizontal screen designed for handling large quantities of sticky materials and delivering precise, fine sizing, making it perfect for numerous construction and mining contracts. The MT620HR model features an recirculating swivel conveyor for oversized product. The conveyor is used to return product back to the feeder.
Adjustable elliptical throw combines linear and circular amplitude producing an aggressive screening action. It excels in handling materials such as natural and crushed aggregates, coal, iron ore, and recycled concrete and asphalt.
