Description

Large-scale Cone crusher

The utility model relates to a kind of size reduction machinery, specifically is a kind of large-scale Cone crusher.

Ultra tiny pulverizing machine (ZL95221892.5) has overcome some significant drawbacks of former Cone crusher, performance is greatly improved, so still have some outstanding weak points to need to improve: 1, owing to structural limitations, crush efficiency is low, output is not high, has limited range of application.As improving pulverizing output with the way that increases the stator and rotor diameter, then temperature rise is accelerated, and wearing and tearing increase the weight of, and reduce service life greatly; 2, the material before pulverizing directly enters the stator and rotor working face, makes the operational vibration of mill big, working face is easy to wear, will change whole rotor, cost height when needing to change after the wearing and tearing; 3, cooling rotor temperature rise difference in bad order is big, has reduced work quality; 4, inconvenience is adjusted in the working face gap.

The purpose of this utility model is to provide a kind of large-scale Cone crusher at the deficiency of above-mentioned ultra tiny pulverizing machine, the improvement by stator and rotor structure and guiding mechanism and the improvement of cooling condition wait and further improve crushing effect and operating efficiency, to satisfy many-sided demand.

Embodiment of the present utility model is as follows: large-scale Cone crusher comprises hopper component 1, ball fairlead 5, stator 6, rotor 11, housing 9, batch mixing pan 14, main shaft, motor, guiding mechanism and advancing, outlet system etc., hopper component 1 is installed on the big nut 3, lever 2 is housed on it, sliding sleeve 4 contains stator 6 and housing 9, ball fairlead 5 is installed in the circular gap of sliding sleeve 4 and housing 9, working end of stator 6 (inner conical surface) and installation end (male cone (strobilus masculinus)) are that axial sequence is arranged, the major diameter of the conical surface is in the stator two ends respectively, the inner conical surface of top installation end and sliding sleeve 4 closely cooperates, big nut 3 is consolidated sliding sleeve 4 and stator 6, stator 6 lower external face and housing 9 big matched in clearance, and have an annular cooling bath, stator feed zone 8 is equipped with on stator 6 working face tops, fixing with pressure ring 7, rotor feed zone 10 is equipped with on rotor 11 working face tops, water ring 13 is housed in rotor 11 cavitys into and goes out water ring 15, water inlet ring 13, go out the inwall looping reservoir of water ring 15 and rotor 11, the lug that two symmetric arrangement are arranged on sliding sleeve 4 and housing 9 outer walls, adjustable diameter and screw adjusting mechanism 17 is housed on it, main shaft upper end dress bell jar 22, pin 23 is equipped with on bell jar 22 tops.

Material enters from hopper component 1, falls into the faying face of stator and

rotor feed zone

8 and 10 along the male cone (strobilus masculinus) of bell jar 22, enters the working face of mill thereupon, is got rid of to discharging opening by batch mixing pan 14 after crushed.Big nut 3 is fastened on stator 6 on the sliding sleeve 4, by adjustable diameter and screw adjusting mechanism sliding sleeve 4 is moved axially with stator 6, adjusts the gap between the mill working face, guarantees needed grinding particle size.Cold water enters housing 9 from water inlet tap 19 during work, to water inlet ring 13 tops, enters reservoir by conduit again, and along with the rotation of rotor 11, heat spills in the water, and water is chewed 20 outflows through going out water ring 15 and pipeline from water outlet.The cooling water of stator 6 is chewed 18 through water and is entered in the cavity of 9 of the annular groove of stator 6 and housings, in order to cooling stator 6.

Ball fairlead 5 is installed for interference between sliding sleeve 4 and housing 9.

Adjustable diameter and screw adjusting mechanism 17 is mainly by handwheel 30, screw rod 29, nut 25, restraint nail 32, housing 28 and be connected and fixed part and form, screw rod 29 runs through the lug of sliding sleeve 4 and housing 9, nut 25 is equipped with on its top, screw rod 29 and nut 25 constitute the spiral width of cloth, bearing 31, dial 33, nut 34 are equipped with in the middle part, lower end dress handwheel 30.Nut is two halves about in the of 25 minutes, are connected dress restraint nail 32 on the lug of housing 9 by key 27 with the lug of sliding sleeve 4.

Because the improvement of stator and rotor structure, governor motion and cooling system, it is bigger that size of the present utility model can be done, and becomes large-scale Cone crusher.

Compare with ultra tiny pulverizing machine and other like products, the utility model also has following advantage except that possessing existing characteristics: 1, stator working end and installation end vertically sequence arrange, stator two ends, conical surface major diameter office, make its dismounting simple and convenient, because interference assembly parts ball fairlead is contained between sliding sleeve and the housing, the dismounting stator need not decompose, and helps keeping the complete machine precision; 2, the charging position of stator and rotor is position easy to wear, has installed stator and rotor feed zone additional, and the wearing and tearing back only needs to change feed zone and need not to change stator and rotor, has prolonged the working life of stator and rotor, has reduced use cost; 3, rotor internal cavity water flowing cooling, improved the condition of work of rotor, because stator and rotor cool off simultaneously, reduced the work temperature difference of the two, reduced the variable quantity in working face gap, guarantee the uniformity of crushing rear material granularity, reduced the temperature rise of material simultaneously, helped grinding the quality of back material; 4, with the gap of adjustable diameter and screw adjusting institutional adjustment stator independently and rotor peripheral face, simple and convenient, be easy to reach required regulated quantity; 5, the rotor upper end is under the bell jar, and it is fixed along the bell jar male cone (strobilus masculinus) flow direction that material enters the back, and the rotor feed zone has reduced the contact-making surface of rotor upper end with material, has alleviated the rotor load, has reduced energy consumption, and grind materials reduces its temperature rise no longer with rotor rotation; 6, owing to stator and rotor structure, the improvement of governor motion and the improvement of cooling condition, it is bigger that its stator and rotor size can be done, and becomes large-scale Cone crusher, thereby raise the efficiency, and increases output, especially grinds more apparent its superiority of the big article of cement equivalent.
