Used Cone Crushers for sale
Cone crushers are used in quarrying to produce a more finely shaped aggregate product than jaw crushers can produce. This results from the grinding action inside cone crushers, where the rock is ground both against the cone and concave, and against the stone itself. Cone crushers are often called secondary crushers, as they are often used after jaw crushers (primary crushers) in a quarry line. You will need a cone crusher if you are producing road grade aggregate. Using a cone crusher is a better option than an impactor where rock is hard(granite, basalt, etc) as it uses the rock to crush itself, instead of concentrating all the wear on the blow bars of the crusher. This extends the life of your wear parts and ensures lower production costs.

With these brands of cone crusher, you can be assured of a long service life, low operating costs and easy parts availability. Ask Sigma for the best options for your new cone crusher. We can also advise on what cone crusher is suitable to fit into your current crushing line.
Cone crusher production outputs
Cone crusher production outputs vary according to the hardness of the rock, the reduction (difference between input and output sizes), but mostly because of the size of the crusher. A cone crusher with a 1-metre diameter will produce about 250 tons per hour, while a 1.3-metre cone will produce up to 350 tons per hour. These are balanced with the jaw crusher to ensure that the cone is the bottleneck in the crushing line, by a narrow margin – this ensures that overall production is maximised, while the cone is choked with stone – this enables the crushing/grinding action to function properly.
