There is Spring cone crusher Symons cone crusher. The safety spring system is the overload protection device which makes foreign material goes through the machine without bring any hurt to it. The sealing modes are oil and water which segregate the stone powder and lubricating system.
Symons cone crusher (spring cone crusher) can crush materials of above medium hardness. And it is widely used in metallurgy building hydropower transportation chemical industry etc. When used with jaw crusher it can be used as secondary tertiary or quaternary crushing.
Spring safety devices are used for spring cone crusher and Symons cone crusher. And at the stage of hydraulic cone crusher they are completely replaced by hydraulic safety devices. More than 50 related parts have also been gradually streamlined which makes the entire structure simpler and easier to operate and maintain.
Overload protection and grease sealing: Symons cone crusher has a built-in spring safety system which plays a role of overload protection. It can filter out foreign objects such as iron blocks in advance to avoid entering the crushing cavity and damaging the internal structure.
