Cone crushers are relatively easy to use and are an economical and efficient means of crushing rock.Modern machines now come equipped with hydraulic clamping and release systems, as well as systems to protect the machine from harmful foreign material.Many older machines, especially by symons and nordberg, are still in high demand and can be refurbished and upgraded to modern standards at a lower cost than a new machine and often more quickly than a new machine can be delivered.
For the customer, the price may be one of the most important factors directly affecting the purchase.Due to restrictions on investment costs and other aspects, second-hand crushers are more attractive to low-investment customers in terms of price.

From the future development potential of infrastructure construction, china's urban rail transit construction is still in its early stages.With the starting of high-speed railway projects in various regions of china, cone crushers and some other related crushing equipment are extensively applied.On the other hand, the domestic subway construction has just started to develop, so it will become another main market for the application of crushing equipment like cone crushers.Compared with other infrastructure projects, the construction of subway will maintain a relatively rapid growth in the long term.At the same time, the large-scale subway construction period will appear between 2015 and 2020.The construction cycle is evidently longer than that of other infrastructure projects.Driven by this factor, the crushing equipment industry is bound to keep a rapid growth momentum in the near future.
