Aerodyne Phenomenon Analyses and Countermeasures of Spring Cone Crusher

2011-05-13 16:24:20

Spring cone crusher is typically named circular crusher, it is product crushing gear which broadly applied in mine,allurgical, construction, chemical, silicate and the like regions. It is ideal for crushing extremely powerful or method tough stonesand rock. Movable vertebrae elements make periodical cycloidal movement having a specific rate when work.But mainly because of some special reasons, the movable vertebrae will improve rate by accident. The entire entire body are heading to be violently vibrated, then creep spring will be on improper functioning conditon, the functioning electrical existing will improve at after as nicely as the temperatures of oil-returnraise quickly, it will end result in gear cannot typical operation, it is named aerodyne.

Spring cone crusher which created by our country, the diameter is among 900mm and 2200mm. The style and design rate is from 220rpm to 396rpm. As usual, the diameter is bigger, the rotate rate is slower. The diameter is smaller, the rotate rate is faster. being a subject of experience, nomatter which crusher, the principal shaft rotate rate or principal shaft sway volume ought to be 5-16 times/min, when the sway volume is more than 18 times/min, it are heading to be aerodyne phenomenon.

1. Classify of spring cone crusher

According to perform demand, it might be divided into 3 modes as follows: basic for method crushing work; brief for thin crushing work; center for medium-thin crushing work.

2. framework of spring cone crusher

It is mostly composed of functioning structure, adjusting device, dustproof device, insurance plan equipment and lubrication device.The functioning framework is created up of crushing mind with manganese metal scale board and adjusting ring. Crushing cone repaired in the principal shaft which under is sphere shape, and supported by sphere condition shaft. The reduced severe of principal shaft is inserted into cone bushing.In fact, adjusting tips is a single component of repaired cone which composed of adjusting bushing, supporting ring,locking nut, generating cylinder and locking cylinder.

Dustproof equipment is created up of sink, detent ring, circular ring and baffle ring.Insurance equipment is mostly insurance plan spring(or insurance plan cylinder), the supporting ring and adjusting ring of spring are heading to be forced up when overload, then it will increase the opening gape and expel completely different materials. Lubricating equipment is composed of lubricating station,oil-return pipe circuit, mostly for supplying lubricating oil.

3. perform theory of spring cone crusher

The rotation of engine obtains although shaft coupling, horizon shaft to create crushing elements sway movement below eccentric ring when work, then to allow ore impacted.extruded and curved continually while in the crusher cavity to attain the crushing of ore.

Motor rotates via bevel items drive, to create movable cone sway motion. To accomplish crush and blowdown, movable cone will near repaired cone sometimes, occasionally leave. Supporting ring and shelf joint require spring to compress. When some non-crushed materials fall to the machine, the spring will grow to be compressive strain and depart from completely different supplies to realize insurance and shield the machine.

4.Epilogue

whenever you grasp the causes of spring cone crusher, then running based on gear structure strictly when in produce. based on upkeep regulations, it may decrease the aerodyne phenomenon of crushers, then can enhance the running percentage of gear and supply reputable ensure for produce.

5. options about aerodyne phenomenon of spring cone crusher

From above analysis, it will display that there are two causes to result in aerodyne phenomenon: a single purpose is lubrication essential oil is below basic or invalidation; another a single could be the gap among movable awl and liner bushing is as well small, so we have to improve it from here.

(1) based on gear instruction strictly to pick eligible lubricating essential oil to ensure basic index, especially viscosity and mobility.

(2) It should fix dustproof equipment with drinking water seal, usually examine baffle ring and annular detent ring. If it is broken, you should alter it in time to ensure the tightness and prohibit the crushing dirt into lubricating system.

(3) To ensure internal and exterior bore’s assembling clearance of awl liner bushing,and ensure touch among main shaft and liner bushing; it should be repaired with operate zinc drinking water among liner bushing and axes bushing, and never any relative motion among them.

(4) You ought to spend consideration for the assembling clearance among excentric sleeve and nylon vertical sleeve: if bias between vacant eccentric shaft and principal shaft, it will result in non-touch among movable awl and eccentric bushing, and make liner bushing nearby overheating, improve the vibration frequency; if as well small, it will result in liner bushing heat of inner and exterior liner bushing.

(5) Touch stage is not permitted below ball surface area 100mm-120mm among bearingbush of ball surface area and movable awl, to make the entire movable awl power supported by world bearing 2/3 above.

(6) Rarity is not permitted while in the round plate when fixed.

6.Some causes for aerodyne phenomenon

(1) Lubricating system.

mainly because of dust-proof loses efficacy or seals imprecisely, some dirt of crusher cavity key in to the lubricating oil circuit to create just about every completely different lubricating component frict crusher bottomnd ball shaft, among movable awl and eccentric bushing, large and little bevel gear, among horizontal axis and shaft bushing. once the temperatures of lubricating essential oil arise approach or exceed 55℃, then viscosity of essential oil will descend.

(2) once the tough supplies enters into crusher, insurance plan spring (insurance essential oil cylinder) willlose function.To make loose the liner of eccentric shaft ,it can decrease the gap among principal shaft of crusher and tapered bushing.

(3) on account of poor lubrication, it will take concerning the abnormal put on among movable awl and ball surface, and end result in ball surface of movable awl decline.

(4).Main shaft will touch the liner internal bore, when the lubrication is not beneficial or even the gap among principal shaft and internal bore of liner is as well small. below this circumstances, awl bushing has left the vacant eccentric bushing, also a extremely important reason to result in aerodyne phenomenon.
