Cone crusher is widely used in fields of those main parts like frame body, adjusting devices, crushing hammer and drive shaft. Cone crusher is appropriate with crushing all kinds of stone with medium-hard rigidity. So you can choose the one for your requirement.
Another important issue you should keep in mind is choosing the product from the right manufacturer. For that you can have less cases to deal with after-sale service and a good quality product can low your working time and make your work more effective. SO before making purchase of a cone crusher, please take the capacity, reputation and scale of manufactures into consideration and search information about them as much as possible.
When cone crusher is working, electromotor will spin through belt ring or coupler. Coupler is located in the center of cone crusher, so the whole system will spin around it then cone crusher can be far away from the facial of adjusting cover smoothly to make stone strongly stricken, squeezed and curved to crush stone.
In this operating process, if there is some unbroken object like metal objects fall into the crushing machine, the mechanical spring would compressed and transformed so that the unbroken objects can be expelled out and protect the machine from being destroyed.
When there is some unbroken thing jam in the cone crusher or over-weighed, the spring would realize security, at this time, issue of the cone crusher expand, then unbroken objects can automatically exude out. There also may be another situation , that is if unbroken objects cannot exude out smoothly, one can use the cleaning off system to enlarge the issue to let those objects exude out. After that, the cone crusher can get right with the help of mechanical spring, the cone crusher machine can work well again. When you want to adjust the cone crusher issue larger or smaller, you can adjust it with the help of hydraulic pressure; you can also do it manually.
Actually, according to the long-term utilization of cone crushers, the work of repair is not so much. For itself, it is with good quality and good equipment, each part of this kind of machine combines to work effectively. It almost works as you expected as long as you choose the right one for your needs.
Of course, everything has two sides. So no matter how good the products are, it still has some occasional matters. Once you are not so lucky to encounter such times, you can follow the products instructions or ask professions to deal with your problem. Please keep in mind that dont repair it with your own imagination if you are not so good at this field.

As we know, the working conditions of cone crusher are harsh. It is inevitable that there will be some problems in the working process of of cone crusher. Knowing how to maintain and repair the cone crusher will greatly help the operators reduce the downtime of the machine. Here are some suggestions for the maintenance and repair of cone crusher.
Bearings: bearings bear the whole load of the cone crusher, so excellent lubricating means a lot to the life of bearings. It directly affects the service life and running rate of cone crusher. in this case, the lubrication oil must be clean.
The minor repair should consist of check and repair or replace about the spherical bearing, repair or exchange of the big& small bevel gear, driving shaft and bearing bush, repair or exchange of the eccentric sleeve and bushing, filter or change the lubrication oil.
The medium repair consists of not only all the procedures in the minor repair but also change the big& small bevel gear, the transmission bearing and spherical bearing. In this stage, the operator should also check the gap between spherical bearing seat and the eccentric bushing and check the spring and spring bolt (for spring cone crusher).
The major repair consist all the procedures in the medium repair and the check, measure, repair or exchange of all the spare parts. Also the operator should adjust the technical features of the whole cone crusher.
In order to solve such problems as low production efficiency and difficult installation and maintenance, ZENITH developed a new generation of jaw crusher--- C6X Series Jaw Crusher. It is the most ideal coarse crushing equipment on current market because a
As the new generation of crusher, PEW Series Jaw Crusher is born with innovative significance. The unique design concept makes this crusher achieve perfect combination between crushing efficiency and operating cost.
Cone crusher is able to rotate, in addition to the outer motor drives , the main parts is the bearing, the bearing can not only make the equipment rotates under the driving of the motor, but also can reduce the friction and improve the crusher work efficiency, is the main component of a device. So, if the bearing is damaged, how can we fix it?
Repair of the cone crusher bearing spherical surface is relatively simple, do not need too much work to complete the repair. On the spherical surface processing should be pre prepare the checking model, spherical radius of sphere radius is slightly smaller than the cone body is arranged on the can, after spotting. The same cone crusher spherical bearing lower conical surface wear after processing, geometric accuracy must use templates to proofread a spherical bearing in the repair process should be consistent with the requirements of table 6-9.
Cone crusher is a very good and can be used for crusher equipment processing usually all kinds of rocks and minerals, in daily use must pay attention to the maintenance of good equipment, do find out and solve the problem, so that the equipment can work better.
During the using process, if the worker operates and maintains the crusher according to correct standards, it will have great significance in normal production, output, quality, service life, working efficiency and the prevention of accidents, etc.
At present, the common cone crushers are mainly the single toggle cone crusher and compound cone crusher (Symons cone crusher). Although both types of cone crushers are totally different, they have the same operation procedure.
The operation procedure of cone crusher can be divided into four stages: before the start, at start-up, at run time and turning-off time. All conditions should be paid attention in each stage, and the potential problems can be found and solved timely and the service time can be prolonged.
Turn on the lubricating oil pump to run for three to five minutes. After everything runs well, turn on the crusher as required. After the crusher idles for one to two minutes, confirm that all things are well, and feed the rocks or stones.
During the crushing process, there is a great impact on the concave which makes the filled zinc layer be out of shape. Therefore, the U-type bolt should be tightened frequently to make the concave fix and avoid concave from deformation.
The mantle is fixed by the upper bolt of the main shaft. The looseness of the bolt can make the mantle unstable, even the filled layer may fall off to cause downtime. Hence, the bolts should be often checked and fixed to avoid looseness.
The spherical bearing should be installed in the borehole of crusher closely. After a long period of working, the tightness of crusher' parts can be broken. The tightness of spherical bearing must be checked frequently, and the oil gallery of the spherical bearing should be kept clean.
Water seal is the equipment for preventing crusher from dust, which is very important to the normal operation of cone crusher. Therefore, daily maintenance and checking its integrality are very necessary.
Through the study of this article, you must have a deeper understanding of the operation and maintenance of the cone crusher. In the case of the above-mentioned failure of the crusher, the problem is analyzed and solved by referring to the method given in this article.
Cone crusher has high crushing ratio, high efficiency, low energy consumption, uniform product size, suitable for medium crushing and fine crushing of various ores and rocks. In the cone crusher working process will encounter a variety of problems, So, we provides 14 common fault causes and solutions!
Table of Contents 1. The oil temperature is too high.2. Oil temperature and pressure rise.3.Oil pressure is low after oil pump is started4.Oil contain lots of fine mud and impurities.5.There is water in the oil6.The vibration of cone crusher is too strong.7. The crushing cone rotates very high.8. The sudden speed of the moving cone accelerates.9. Non-uniform rotation of transmission shaft10. Make splitting sounds.11. The coupling rotates and the crusher does not move.12. The drive shaft produces a strong knock.13. The supporting ring jumps.14. The size of ore discharging increases.
Cause: The quality of the oil is poor or the oil is insufficient; the bearing is damaged; the ambient temperature is high, there is no cooling water or the cooling water pressure is low; the cooler is clogged. Solution: change oil or refuel; change bearings; supply cooling water or increase the pressure of cooling water; clean the cooler.
Causes: water enters the lean oil station; the cooler leaks, and the water pressure is greater than the oil pressure; water supply too much or the return pipe is blocked. Solutions: Clean oil tank and replace oil; repair leakage or replace cooler, reduce water pressure, clean oil tank and replace oil; adjust water supply or clean water return pipe, clean oil tank and replace new oil.
Causes: Cone crusher base is loosening; Difficult-to-break materials enter the crushing chamber, leading to blockage; parts break or wear; poor lubrication makes the spindle tightened by bushing. Solutions: fastening bolts, pouring; controlling the type of feed, strictly forbidding the entry of non-fragments; strictly controlling the amount of feed; stopping the machine to check accessories; replacing damaged parts, repairing oil pumps and pipelines.
Causes: oil shortage or dust in oil between spindle and bushing; insufficient clearance of tapered bushing; wear or manufacturing reasons of bowl bearing bush, contact surface deep to inner circle, conical body sinking. Solutions: overhaul or replace bushings, spindles, etc., and find out the causes of oil shortage, eliminate it; adjust bushing clearance; re-scrape, and meet the requirements.
Causes: serious wear or damage of gears; damage of connection keys; breakage of spindle. Solutions: stop and replace gears, and make meshing clearance meet the requirements; change the connection keys; change the spindle, strengthen iron removal work.

Turn on delivery belt and pull the lube/ hyd button to bring cone down. hyd wont engage. Changed the contacts on the pull button. Nothing. Swap soil nods no go.
The cone crusher can not be restarted immediately when it stops suddenly, so as to avoid secondary damage to the cone crushing production line. First of all, you should find out the reasons for the sudden stop of the cone crusher, there are 5 common reasons:
1. The discharge port of the cone crusher is blocked, too much or uneven feeding will lead to the blockage of the discharge port, resulting in excessive production load of the crushing machine, resulting in the fracture of the fuse and lead to shutdown.
2. Sudden shutdown may also be caused by too low or too high voltage, unstable voltage or easily forcing the cone to break self-protection resulting in shutdown. So be sure to check whether the voltage is normal before turning on.
3. It may be the eccentric shaft problem, the eccentric shaft fixed bushing loose or falling will lead to no gap between the bearing housing and the frame, resulting in the eccentric shaft can not operate, so the cone crusher will stop suddenly.
First of all, before starting up, check to see if there is any residue in the tapered discharge opening, clean it up immediately, and pay attention to control the feeding evenly, not too much or too little.
The second is whether the belt tightness is appropriate, reasonable adjustment to prevent too tight or too loose. In addition, pay attention to the voltage situation to maintain the stability of the voltage.
