Used Jaw crushers for sale
Sigma have availability of used tracked and static jaw crushers for sale. Jaw crushers are often called primary crushers as they take material straight from the blast face in the quarry and do the first crush. This produces a rough, ungraded aggregate with sharp edges, and in size will be anything from the minimum size of the jaw down to dust. This stone can be used for rough backfilling, but usually has to be further processed for use in road base, asphalt or concrete. The secondary crushing is either done by an impactor, for softer stone, or a cone crusher, where rock is granite, basalt or another hard rock. A typical crushing line for asphalt grade stone consists of a jaw crusher, eg Sandvik QJ341, a cone crusher like a Sandvik QH331, and a three deck screen like a Sandvik QA451. This will give the four products required for asphalt.
Mobile jaw crushers
Sandvik are a world-class manufacturer of jaw crushers, and Sigma supply used jaw crushers from Sandvik, Metso, Kleeman, Extec, Terex Pegson Powerscreen and Parker. If you are looking for a used jaw crusher for sale, please enquire and we will be glad to advise you on your next jaw crusher. Hard rock reduces crusher output, and where the rated output is 400 tons per hour, you may achieve 250-300 tons per hour on harder stone. Mobile jaw crushers are used because of their flexibility in moving either between job sites – essential in contract crushing or short-term construction projects – or just around a quarry. Mobile crushers can be moved right up to the quarry face to crush, removing the need for dumpers and double handing of the rock, and moved away to safe positions while blasting.
