Dura Equipment Sales has the widest range of used mobile screens and crushers available for you to choose from. Screens and crushers are an integral part of both the mining and construction industries where they provide sized rocks for further processing. Screens and crushers usually work in tandem with oversized rocks being crushed to a predetermined size by means of either a jaw or conical crusher. From the crusher, the resized material travels over a series of screens that can separate rock sizes ranging from fines to a number of predetermined sizes. Depending on its usage for mining, quarrying or construction the aggregates will be stockpiled or further processed as required. Crushers and screens are used in the mining, construction, industrial and plant hire industries.
