Mantle is the important part in conic crusher, need and assorted bolt, spherical bearing closes suitably, and with on, next lining close suitably, aborning hard to avoid can be worn away, the article basically introduces the account that conic broken mantle damages, reach how to reduce mantle wear away prolong its service life.
Mantle attaint reason
Into makings property disagreement asks
Bedspring reduces an amount undeserved
After conic crusher investment is used, if have efficiency of oscillatory and acuteness, production size of low, product is large wait for a phenomenon, it is the expression that conic crusher reduces force to be not worth. Have some of success that manufacturer produces to assure, meeting the compression of readjust bedspring is measured, although increased the compression of conic crusher force, but accentuated however the working load of mantle, cause the damage of mantle.
Equipment excess load runs
Act on much brokener grind less, fall the producer needle of this synergism, a lot of manufacturer can pass the size that reduces eligible ore deposit further, increase the method such as mine quantity to improve conic crusher productivity, cause movement of long-term excess load, the burden of ministry of farther aggravating mantle, if things go on like this, will cause the damage of mantle eventually.
Mantle suffers concussion more frequent
Should have inside conic crusher be not broken content to enter airframe, give mine into makings mouth not all or attaint of crock of conic crusher locking, can bring about mantle suffer concussion bear is more frequent. When the intensity limit that approachs mantle when bear of the concussion when some an instant, its weakness place can be destroyed, produce petty micro-crack. In burden, hand in change long-term effect issues negative charge, micro-crack is progressively and patulous, cause mantle damage finally.
Mantle suffers force disequilibrium
When conic crusher mantle works, force basically has its susceptive the counterforce of the counterforce of the self-prossessed force of awl of pyramidal force, activity, spherical bearing, prejudicial axle sleeve, broken awl and prejudicial axle sleeve (include counterbalance) force, if the join forces of these force is not zero hour, mantle can suffer force disequilibrium, bring about equipment vibration too big, mantle damage.
Mantle becomes loose
Because mantle head and main shaft whorl are both between tighten force to did not detect beforehand tool, overhaul worker holds by experience in real work, stop after the gear clench the teeth that uses gear and conic head, tighten requirement of technology of force short of beforehand. When conic crusher bear moves, conic head becomes loose to cause what gear reachs mantle put oneself in another's position to wear away thereby.
The surface contact that prop up is undesirable
The mantle bearing of conic crusher is in spherical bearing on spherical plain bearing liner, wear away when spherical plain bearing liner or put when quality problem, can create mantle system next moving, its prop up interface cannot good contact, cause aggravate of mantle body attrition to bring about its to be damaged badly thereby.
How to reduce mantle to wear away, prolong service life
1, strict control is entered makings. Before using conic crusher, should understand conic crusher to operate common sense and note, make clear the conic crusher requirement to broken stock, prohibit according with equipment the stock of broken requirement enters facility inside.
2, install mantle correctly. In the installation process of mantle, want special attention of the working surface such as prejudicial axle sleeve, spherical tile, cone-shaped lining, frame straight lining dustproof. Installation hind determines to cooperate face clearance and osculatory area each with soft lead, those who make accord with a regulation. If examine,spherical tile decides awl ball surface contact together ministry area, make sure its core area is between 0.5-1mm, area of its outer shroud is between 0.6-0.7mm.
3, reduce mantle become loose. Stop through take out use gear, be in conic head and pressure set between increase the annulus that cut frit to wait, when conic crusher bear runs, the roll that can use minute of charging tray and conic head comes back automatically close, reduce mantle body to become loose cause wear away.
4, the impact that reduces chunk stock. Aborning should notice to prohibit piece spend big stock to enter conic crusher inside, necessary word can undertake blowing up to chunk stock, send broken pitch again inside, reduce chunk stock to wear away to the concussion of mantle.
5, improve mantle to accept strength condition. Through hydraulic pressure device is being installed in bottom of conic crusher base, make of mantle ministry self-prossessed all assume by hydraulic pressure crock with the perpendicular component of force when broken ore, in order to improve the condition getting power of mantle, make its movement stable and reliable, the damage of mantle can reduce on certain level.
6, the examination in noticing production. Once conic crusher mantle appears unusual when, all operation personnel should stop in time machine is hand-in-hand the examination with comprehensive travel, perhaps inform professional maintenance technician undertakes be repairinged professionally, if be the spherical bearing of conic crusher,appeared to injure, undertake in time maintain or changing with respect to need, undertake in time adjustment to clearance of mantle taper lining, assure to have enough space among them.
7, reliable insurance unit. Traditional and conic crusher uses bedspring insurance device commonly, but dependability of unit of this kind of insurance is low, choose unit of hydraulic pressure insurance commonly nowadays now, when equipment crosses iron or overloading, unit of hydraulic pressure insurance can act well instantly, reduce the damage of conic crusher overload to mantle.
8, precautionary mantle unbalance. Because mantle unbalance can make conic crusher produces casualty, can appear even main shaft ruptures, break off, the breakdown such as cone-shaped lining craze. Because this aborning should notice precaution moves unbalance of conic crusher mantle, when discovering mantle unbalance, should find out a reason in time and eliminate, lengthen mantle and its equipment the service life of each component.
9, lubricate goodly. Before conic type crusher begins the work, should examine the lubricant condition of mantle, whether is there foreign matter inside examination lube. In the locomotive process of mantle, should note the temperature of lube, the attention assures the dredge of oil path, when lube is degenerative, should filter in time or change clean lube, those who assure mantle is good and lubricant.
Reduce the wear rate of mantle, shorten its change cycle is to reduce conic crusher to produce cost, raise the important step that produces beneficial result. When if encounter mantle,wearing away badly, must search an account in time, solve as soon as possible, resume production.
