If the equipment appears problem will directly affect the production efficiency affect the profit. So what are the cone crusher Common malfunction
Crush machine appears to get stuck is often due to some sudden malfunction. And it will affect the normal production seriously also reduce the service life of equipment and parts. The three main phenomena of cone breaking and sticking are as follows
Too much feed or the material unqualified may cause the stone crusher machine jam up. The machine works electricity too large lead to circuit automatic protection and stops the machine. Much more serious may turn up the machine halt because of jam up. And when there is iron ore or other unbreakable material in the cone crushing chamber it also will cause jam up even get stuck.
One of the main reasons for the shaft break is the improper use of the cone crusher. For example in order to achieve the required fineness of the discharge and constantly tightening the discharge gate. Then the unbreakable material enters the crushing cavity. It has a cool impact on the shaft thus causes the cone to break the main shaft to break to jam.
On the other hand when the crushing machine in an overload state for a long time the main shaft is easy to break and cause the equipment to jam. It can not completely avoid the damage of the crusher plant even though has an overload protection device.
When the stone crusherwith load operation due to the loss of pressure in the hydraulic station locking failure the adjustment setting will follow the cone rotation. It will cause the phenomenon of adjustment set stuck if the operator is not found in time processing. Thereby leading to the stone crusher machine shutdown.
Because the speed of eccentric sleeve of cone crusher is very high which is much faster than the rotation speed of the main shaft it determines that the contact position between the main shaft and the cone sleeve will change. When the number of contact positions decreases the force on the contact position will increase.
Cone crusher crushed stone production line site Fault 4 The oil temperature exceeds 55 but the oil pressure does not rise. Causes of failure There is something wrong with the eccentric bushing Troubleshooting method stop and check the straight bushing and cone bushing to find out the cause of the fault and clear it.
When the dry friction between the main shaft and the cone sleeve of the cone crusher causes the temperature of the contact position to rise it will result in the expansion of the cone sleeve and other serious consequences. As the temperature value of eccentric sleeve is usually less than that of copper sleeve and the wall is relatively thick as far as the expansion coefficient is concerned the steel is relatively small so the expansion is relatively light and the overall impact is small which means that when the expansion occurs the expansion direction can only be inward.
The distance between the main shaft and the cone sleeve will be narrowed which will further aggravate the problem of heating. The gluing between the main shaft and the cone sleeve will also deteriorate the speed of the main shaft is faster and faster which result in ldquorunawayrdquo breakdown. The clearance between the main shaft and the cone sleeve of the cone crusher should be set reasonably not too large or too small.
1 The inner wall quality of the cone sleeve is not up to the standard which leads to the contact between the cone sleeve and the main shaft damaging the oil film and causing the spindle speed out of control
2 The clearance between the main shaft and the cone sleeve is not scientific. If the clearance is too large it will lead to the impact between the cone sleeve and the main shaft. If the clearance is too small the lubricating oil at the contact part is not enough and it is impossible or difficult to form an oil film
5 The excessive load of the cone sleeve causes the zinc pouring to fall off thus reducing the clearance between the spindle and the sleeve resulting in the phenomenon of quotshaft holdingquot
The Main Reason Of Flying Carfailure Of Cone Crusher. Due to the failure of dustproof device or lax sealing some dust in the crushing cavity enters into the lubricating oil road resulting in poor lubrication between lubrication parts the bottom of the crushing cone and spherical bearing the moving cone and eccentric sleeve the bevel gear and the horizontal shaft and the shaft sleeve and oil .
Aug 01 2019nbsp018332The parts of the cone crusher will be affected by the harsh working environment when working and various failures such as wear and breakage may occur which may even jeopardize the cone crusher. Proper use of the cone crusher and reduce component failure rate have become a concern for every user. The cone crusher has a complex structure and .
Rock crushers are complex machines. When they fail its often due to one of three relatively simple principles
Lets take a look at each so that you can avoid these mistakes and keep your rock crushing plant operating efficiently.
This ones pretty straightforward If a crusher is used in a way it shouldnt be it is more likely to fail.
The first is that rock crushers are intentionally used to crush material they arent equipped to process. Typically this means attempting to crush material thats too big at too large a rate of reduction skipping a necessary secondary or tertiary crusher and going for throughput that is too small. If material is too large for a given crusher then it will be harmful for the crusher to process. Running a machine in this way for any extended period of time will cause damage that will make failure more likely.
The second way this happens is that crushers are forced to process too much uncrushable material. This is particularly common for cone crushers. For example if a quarry isnt clean and yields too much clay crusher performance can suffer and failure may eventually result.
The bottom line is that crushers are less likely to fail if they crush what theyre designed for.
A second common reason that crushers fail is because they go too long without needed maintenance.
Crushers are complex machines and just like any complex machine they require regular care. Every crusher part requires maintenance in order to continue functioning optimally.
There are many different ways that maintenance failure can lead to crusher failure
