Cone crusher "speed" need downtime, so that normal production operation is interrupted, to cause a lot of loss of production operations. Moreover, single cone crusher, "Speed" is also the hazards of the device can not be ignored.1. cone crusher run with a load of "Speed" and time to discharge the ore is broken on a process ore is continuously fed into the crushing chamber. This will inevitably result in blocking mine, causing crusher overload, causing burn out the main motor or bevel gear teeth broken and other accidents.
2, cone crusher "Speed" will result in the lubricant thinning and large number thrown from the bowl-shaped bearing. If the treatment is not timely, lubricants lost too much oil level decreases causing oil supply disruption, caused damage to the transmission parts.
Pyramidal high-speed operation and highly volatile, resulting in severe vibration bowl bearings withstand tremendous impact load. If you do not stop in time, can cause damage to the bowl-shaped bearing cracking.
4, cone crusher long dramatic "Speed", drogue also cause cracking or burn out, parts of the spindle drogue burning point in spindle formation shades of annular grooves.
5, eccentric sleeve and burn point contact area due to fever inward expansion, can not be fully recovered after cooling, resulting in permanent inward bulge deformation. If you do not deal with the load drogue place can not be due to the deformation of the tapered bore, the drogue eccentric shaft hole between the gap. Put into use causes the drogue so quickly fall off or cracking.
Eccentric sleeve thermal deformation and sometimes also reflected in the thin side cylindrical contraction with the loose, and even caused the shedding of the large gear, bevel gear with eccentric sleeve.
