Recently a new R & D production WKS cone crusher is the PY series spring cone crusher improvement, optimization, updating and replacing product. This kind of cone crusher is suitable for crushing various minerals and rocks of moderate hardness. Compared with PY series spring cone crusher, WKS cone crusher has the advantages of reliable structure, high production efficiency, convenient adjustment, economic and other characteristics. The spring system is the overload protection device, which can protect the crushing chamber from damaging when the metal foreign body through, using dry oil seal form to make the powder and the lubricating oil isolation and ensure reliable operation.Hydraulic cone crusher is one of the high energy cone crusher of the world"s advanced technological level which is designed and developed by the senior technicians from home and abroad, which not only improves the production capacity and the crushing efficiency, but also enlarges the use range which is from limestone to basalt, from production of stones to crushing all types of ore, and it can efficiently complete various types of crushing such as the work of fine, super fine crushing. The Hydraulic cone crusher is with advanced crushing principle and technical parameter, it also runs reliable with low cost, big crushing ratio, high yield, and high efficiency.Hydraulic system is convenient and reliable, which provides safe and effective overload protection.With many kinds of crushing chamber satisfy the different requirements of the product size.Using the hydraulic zero setting and hydraulic cleaning chamber setting greatly improves the automation of the crusher.With hydraulic pressure adjustment, thin oil lubrication and effective way of the labyrinth seal,it fundamentally eliminate the common malfunction such as the oil-water mixture of old spring cone crusher.mobile stone crusher plant:http://www.fote-machine.com/product6.html
