Cone Crusher Problems
cone crusher problems
Cone Crusher Description:
Cone crusher through the use of the intergranular laminated design principles of the special crushing cavity and contrast to match the speed to replace the traditional single particle crushing principle, to achieve selective crushing of materials, a significant proportion of product fines and cube content to a great extent to reduce flakiness materials. Its unique lubrication system design, greatly improving the service life of equipment. High-performance non-contact labyrinth seals, no wear and improve the reliability of blocking dust, virtually eliminating the original spring cone crusher oil mixed with water and other common failure to improve life. I produced a series of highly efficient Hydraulic Cone Crusher production capacity, the best products of stone shape, and easy automatic control, with the greatest reliability and flexibility, and real users to create more value.
Working Principle:
The main structure of the hydraulic cone crusher cone crusher including feed hopper on the rack department, moving cone, the base row of hopper, drive shaft, belt, motor and other assistive devices, hydraulic lubrication station, cabinet .
High efficiency Hydraulic Cone Crusher work when the motor through the belt, drive shaft, drive gear driven by the eccentric sleeve rotation, moving cone in the eccentric sleeve role rotary pendulum movement, the movable cone and fixed cone and sometimes near and sometimes deviate from. Materials continue to be squeezed in the crushing cavity, the impact of the broken, the broken material from the lower part of the discharge.
Cone Crusher Problems:
Cone break during use, the most prone to the following questions in a timely manner to guard against the:
1, The oil temperature is too high.
Reason: bad oil; fuel shortage; bearing damage.
The elimination method: oil, or fuel, or replace the bearings.
2, Low oil pressure, the pump is activated or indicator oil flow.
Reason: low oil temperature; tubing blocking.
The elimination method: hot the oil, or make the tubing throught.
The Notice:
1, correct use coolers
Crusher oil temperature should be maintained at 38-53 ° C, optimum operating temperature range of 38-47 degrees Celsius in this range to ensure the stable performance of the lubricants. When the temperature rise to 55 degrees Celsius when the environment or job, you should use the oil cooler. Conditional units, install a temperature control valve in the lubrication system, automatic control of cooling water into the cooler. If the temperature control valve is not installed, you should install a ball valve, in order to manually adjust the amount of water through the cooler. The size of the water must be determined based on the working conditions of ambient temperature, as well as crusher, the aim is to make the lubricant temperature is stable at 38-54 degrees Celsius range.
2, a variety of electrical protection facilities intact
The crusher has a variety of protection devices, such as the hydraulic protection set the value 2PSI and 3PSI supply crusher lube oil pressure is below the minimum safe working pressure 3PSI, pressure switches control automatic alarm, stop to the mining delay of two minutes to stop the crusher; driving oil pressure interlock broken 4PSI can not be started. Flow protection, the normal amount of oil is about 227 246L/min will automatically alarm when flow is lower than 226L/min crusher. There back to the oil temperature protection. If the crusher in the oil-free state work for more than 2min will of the crusher to produce significant damage. In the production process, will inevitably encounter this situation, if not the first to start the lubrication system and start the crusher; lubrication system suddenly stop the pump, pipe blockage or rupture of other faults in the normal operation of the process. If the protection device is normal, the former will not be able to start the crusher, to protect the role of the crusher. If the protection fails, it will have significant damage to the crusher. So, all the protective equipment should be inspected regularly to ensure good and effective.
3, dust control system
The main problems in the system water often enter the tank, causing a series of failures, resulting in the crushing machine does not work. The reasons why tank water: the water is too large; plug the water chamber; moving cone speed is too fast through the tracheal blockage. Countermeasures to be taken are: the inlet pipe to install a water saving valve; the disintegration of the crusher to find out the reason caused by the moving cone speed is too fast; frequent cleaning of the water chamber, the special is the disintegration of the crusher sure to clean the water chamber; guarantee the smooth flow of the ventilator in order to ensure atmospheric pressure inside the machine thus ensuring the smooth flow of lubricating oil and water cycle, so at least a week should be cleaned once installed on the horizontal axis of the side and fuel tank air filter.
4, no-load operation
Crusher in the no-load operation, the spindle pressure to the thin edge of the eccentric sleeve (left) appears to the left of the gap, the thickness of the eccentric sleeve side pressure to the rack bushing (right), the left gap. Therefore withstand greater pressure on the thin edge of the eccentric bushing in the no-load operation, if the no-load operation for a long time, it is easy to damage caused by eccentric sleeve. Such cases have occurred in the actual production process should be carried out after the disintegration of the crusher maintenance test run, I think not more than 30min. When adjusting the crusher Pai mine mouth takes less time, generally in the no-load operating conditions. If the adjustment, you can adjust the row in the no-load operation state of the mine mouth. But significant reduction in time was needed if the adjustment should be shut down, tune port of discharge, to be adjusted to a certain level and then turned on and continue to the port of discharge to adjust appropriate, it can avoid the long no-load operation.
5, power control
The crusher around the crushing chamber to 360 ° uniformity to the mine, crusher processing capacity in this state, uniform particle size, minimum bearing pressure, power consumption is the lowest, but also to extend the lining life. Feed uneven, and vice versa. To achieve uniform ore mine in the crushing chamber to try to cloth much more, but not so full of ore. Enable power control, you can solve the feed problem.
6, on the broken material
Crusher iron, is a cause enough attention. Occasionally over the iron and iron crusher great harm will lead to the crusher liner, bush rupture, the worst case even lead off the spindle. Therefore, before the crusher should be the installation of iron removal device.
