Spring cone crusher is suitable for the mineral ore and rock whose hardness is above medium.The structure of cone crusher is reliable, the production efficiency is high, the adjustment is easy, and the cost is low, etc.Its spring insurance system is overload protection device.It can protect the machines from damage when some super hard objects (such as iron, etc) pass the crushing cavity.It uses oil or water sealing forms, which can make limestone separate from lubricant and ensure cone crusher work reliably.The discharge size of materials decides the type of crushing cavity.Standard machine is used for medium breaking, and medium and short machines are used in finely breaking.When the cone crusher work, motor drive the excentric sleeve rotation through horizontal axis and the bevel gear.Movable vertebrae move a rotation movement forced by excentric sleeve, which make the gap between crushing wall and rolling mortar wall change repeatedly. The materials are broken by extrusion and constantly hitting in the crushing cavity. Negotiable
