It will be helpful for operating or choosing a cone crusher if we are able to understand the Cone crusher's internal structure,this paper gives brief introduction.
1, Rack
Rack is rigid frame wall with openings above and below which is used as a support to the eccentric shaft and withstand the crushing material reaction.It requires sufficient strength and stiffness and generally integrally casting with cast steel, it can be replaced as quality cast iron for small Crusher. Mainframe rack required sub cast,then firmly linked together as a whole with bolt. The rack which is casted with thick steel plates can also be used for small cone crusher , but it has less rigidity.
2, Jaw plate and side guard plate
Fixed jaw and moving jaw are both composed with jaw bed and jaw plate, jaw plate is the working part and is fixed with iron bolts and wedges on the jaw bed. The jaw bed of fixed jaw is the anterior wall of the rack, A moving jaw bed hanging on the walls and should have sufficient strength and rigidity to withstand the crushing force, most of which are steel or cast iron so.
3, Cone crusher transmission parts
Eccentric spindle axis is the spindle of a crusher which have great bending-torsion as manufactured with high-carbon steel.Eccentric parts need to be finish machining, heat treated and the bearing pouring with babbitt alloy. Eccentric shaft mounted pulley at one end and install flywheel the other end.
4, Cone crusher control device
Control device has wedge block type, pads type and hydraulic type,etc.,in which wedge block type is generally used, composed of two block wedge in front and back.the front one can moves frontward or backward, resisted the back pushed board; the back wedge block is for adjusting and can mobile up and down with screw arbor and control the size of discharging gate.However the discharge gate of small cone crusher is controlled by increasing or decreasing the number of pad between the pedestal and rack.
5, Cone crusher flywheel
Cone crusher flywheel is to store energy for moving jaw travel and formation for industrial, enable the mechanical work in accordance with the uniform. Pulley also plays as a flywheel. Flywheel is often manufacturing with cast iron or cast steel , minicomputer flywheel is often made into one-piece.Static equilibrium should be paid attention to during the process of Manufacture and installation. .
6, Cone crusher lubrication device
Eccentric shaft bearings are usually centralized lubrication. Spindles and the bearing surface of the thrust plate commonly used grease by hand grease gun oil. Moving jaw angle is very small, causing the lubrication difficulties between the spindle and bearing.It is usually the case we open a several axial bearing oil groove at the bottom of bearing shell, driving a circumferential oil groove in the middle to make it connected, then forced injection with oil pump dry butter lubricating.
It will be helpful for operating a cone crusher of when problems occurs during which if the user is able to understand the Cone crusher's internal structure prior to the purchase.
