In the design of the quarry crusher, generally want the stability of the moving cone design to ensure no dynamic cone instability phenomenon in the operation work. But in the working process of the crusher, there are many factors that can affect the stability of the moving cone, so it occurs when the moving cone instability phenomenon. So, the impact of Conic stability factors, what does?
1) contact with a spindle taper bushing next port
If the cone bushing have a place to be fracturing, it shows the spindle taper bushing in contact with the place, by the reaction of spherical bearings, spherical bearings outside the scope beyond, moving cone instability will be overturned in a tapered bushing inside the card, thus cause coaster accident.
2) maintenance quality ball bearings
When the quarry crusher load , when acting position outside the spherical bearing reaction forces beyond spherical bearings, moving cone inevitable instability and overturned. In the maintenance of the quarry crusher, which is not good if the spherical contact tip over and stuck in the cone along its inner bushing in contact with the spherical bearing half of the central angle will decrease, moving cone will lose stability, resulting in runaway phenomenon.
To prevent this phenomenon, Conic ensure stable operation, maintenance must contact area of the entire spherical bearing contact with the outer ring 2/3. 1/3 laps remaining in the area do not contact until after a period of time is needed to achieve full uniform contact. Shredders have upload after quarry crusher overhaul, if the spherical bearing and fixed cone spherical contact in Circle. But not too serious, often used to operate the mine for some time, the situation will improve contact spherical bearings, thus breaking into the normal operation of the opportunity.
3) Other factors
The first two factors are due to the location of the contact point moving cone instability caused by improper, in addition, the eccentric component mismatch face local contact or gap or oil dirty oil can cause the reasons for higher dynamic cone instability generated Speed phenomenon.
4) the combined effects of multiple factors
By a combination of factors affecting lubrication, clearance, tilt and eccentric bushings and other local contact with each other, creating a vicious cycle will eventually lead to runaway accident.
