The reasons of cone crusher coaster phenomenon

Cone Crusher is a widely used in mining, metallurgy, construction, chemical, silicate materials, broken equipment and other fields, is suitable for crushing hard and medium hard ore and rock. According to feedback from customers cone crusher  summed up the phenomenon of runaway production and tactics for breaking the user reference cone.
Cone Crusher mainly by the work of agencies, adjustment devices, dust-proof devices, security devices, and lubrication devices and other components. Organizations from manganese steel liner with a cone and fixed cone crusher (also called adjustment sets) form. Crushing cone mounted on the spindle, its lower surface for the spherical shape by the spherical bearing support. Spindle into the bottom of the cone set in eccentric kit.
Normal production process of the dynamic cone crusher cone section to a certain rotation speed to do periodic pendulum movement, but often because of some special reasons, they would often move cone speed suddenly increased, the body produces instantaneous asked violent vibration, spring or insurance, the insurance cylinder in a non-normal working condition, operating current increase in the instantaneous asked to return to the oil temperature increased rapidly, resulting in equipment can not function properly, this is the so-called "Speed."
1. The reasons for the phenomenon caused by Speed
(1) lubrication system. As the dust-proof device failure or strict closure. Some of the crushing chamber dust into the lubricating oil (the normal working hours can not be broken into dust generated inside the machine and fell into the tank to be washed away by circulating water), so the lubrication site, including broken between the cone base and the spherical bearing, dynamic Lu cone and the eccentric sleeve, between the size of bevel gear, the horizontal axis and poor lubrication between the sleeve, resulting in friction. Lubrication oil temperature continues to rise, reaching or exceeding 55 ℃, the viscosity of the oil drop.
(2) crushing chamber into the non-broken thing, insurance springs (or insurance, fuel tanks) have lost their role in bringing empty conical eccentric shaft bushing loose on the string, reducing the broken shaft and the taper bush news gap.
(3) The poor lubrication, resulting in dynamic cone-watt non-spherical and spherical Bowl normal wear and tear (especially the spherical bearing Bowl Pad Wear severe), resulting in decreased dynamic cone sphere, so that mattress moving cone and cone-shaped cover the gap between reduced.
(4) Spindle and bushing bore partial contact with poor lubrication. Or spindle taper bushing bore gap is too small, so that embraced spindle taper bushing. In this case, the cone has left the empty set of eccentric sleeve, also contributed to the runaway phenomenon of frequent reason.
2. Should taper breaking "speed" measures
As can be seen from the above analysis, resulting in cone crusher coaster for two main reasons: First, failure or failure of lubrication; second, moving cone and cone-shaped bushing gap is too small, so our responses to it from two aspects:
(1) in strict accordance with the requirements of the selection of qualified equipment specification oil, ensure the indicators meet the standard, particularly its viscosity and fluidity (if in the cold, winter oil should be warm, to ensure its liquidity) .
(2) dust seal must be installed devices, regular checks of retaining ring and ring ring, if found by a bad or damaged shall be promptly replaced. Guarantee seal, sitting against broken into powder lubrication system.
(3) that taper bushing assembly within the bore hole outside the gap, to ensure spindle taper bushing along with full contact (an increase in the spherical bearing seat pad tiles can be changed and fixed cone sleeve press gap); cone shaped bushing and shaft sleeve must be fixed with the melting of zinc water to live, between the two can not have any relative motion.
(4) Note that empty eccentric sleeve with nylon (or copper) vertical gap cover assembly heard: too much air causing a great eccentric axis and tilt axis, resulting in not moving cone and eccentric line of contact, make the local bush overheating, increased swings, increased vibration; too small will cause fever inside and outside the bush.
(5) spherical bearing pad and moving the body the next spherical cone 100mm - 120mm or less allowed to have contact points. Makes the power of the moving cone from the spherical bearing upper 2 / 3 spherical bearing.
(6) installation of attention within the circular plate (below) not to enter the foreign body.
Speed control of the cone crusher reasons, and in the actual production equipment in strict accordance with the operating rules for operations, maintenance procedures in accordance with equipment maintenance, we can reduce the crusher Speed phenomenon, greatly improve equipment operating rate, to improve productivity and production efficiency to provide reliable protection.
