HCC Hydraulic Cone Crusher is widely used for secondary and fine crushing in the fields of mining, building materials, metallurgy and so on. It can crush materials with middle and high hardness, such as ironstone, copper ore, granite, basalt, cobblestone, marble, limestone, and so on. It is popular to the high automatic crushing line which has strict requirements for finished products' shape and ratio.
Working Principle of Hydraulic Cone Crusher
When it works, the motor drives the drive shaft through the pulley and V-belt .The drive shaft and a pair of bevel gear make the eccentric sleeve rotating and this makes the cone axis swing, so sometimes the crushing wall is near the rolling mortar wall, but sometimes they are far away from each other. Stones in the crushing cavity are extruded, impacted, and boned continuously, finally they are crushed.
Features of Hydraulic Cone Crusher
The crushing cavity is special designed according to particles layer pressure principle, the special cavity and the suitable rotary speed improve crushing ratio and capacity, so does the cubic product percentage.
With hydraulic protection and hydraulic cavity cleaning, the machine is high automatic, if something abnormal happens, such as iron is feed into the crushing cavity or there is a jam in the cavity, the machine will lift up the cover and discharging the material automatically., this eliminate the trouble of stopping the machine to discharge the material by workers, so the maintenance is easier, the cost is lower than spring cone crusher.
It is adjusted by hydraulic device and lubricated by diluted oil. The labyrinth seal eliminates the defect of mixture between water and oil in the traditional spring cone crusher.
