Description

A kind of twin-stage ball mill
Technical field
The utility model relates to mine mechanism technical fields, more particularly to a kind of twin-stage ball mill.
Background technique
Ball mill is after material is broken, then the key equipment crushed.It is widely used in cement, silicate system Product, the production industries such as New Building Materials, refractory material, chemical fertilizer, ferrous metal and non-ferrous metal can be to various ores and other Grindability material carries out dry type or wet type grinding.
The working principle of existing ball mill is as follows, and during equipment operation, material and mill ball in ball mill are being rolled Make partial circular motion upwards under the drive of cylinder, then fallen by gravity, shock occurs with material and reaches comminuting matter Purpose, during the work time, the material ore in sand form different at granularity by grinding, qualified ore in sand form is directly from discharge port for existing ball mill Discharge, unqualified ore in sand form, which persists in, carries out grinding in ball mill ontology, at this point, the smaller ore in sand form of the granularity in unqualified ore in sand form It can be coated on around the larger ore in sand form of granularity, play a protective role to the larger ore in sand form of granularity, the larger ore in sand form of granularity is caused to be not easy grinding, Grinding time is long, and mill efficiency is low, and ore grinding effect is poor.
In conclusion need it is a kind of can improve mill efficiency, reduce the ball mill of grinding time.
Utility model content
The purpose of this utility model is that: it is mixed in order to solve conventional bead mill various granularity ores in sand form during grinding ore It closes, causes to roll ball and roll low efficiency, to the problem of ore grinding effect difference, provide a kind of twin-stage ball mill.
The utility model specifically uses following technical scheme to achieve the goals above:
A kind of twin-stage ball mill, including ball mill ontology, ball mill body interior are equipped with and roll ball, ball mill ontology one end Equipped with feeding mechanism, the ball mill ontology includes inner barrel and outer barrel, and sieve material mouth is respectively equipped on the wall of the inner barrel and outer barrel And discharge port, sieve material mouth aperture are greater than discharge port aperture, the inner cylinder outer surface is installed with pressure roller, and the ball mill ontology other end is set The driving mechanism for having driving inner barrel and outer barrel to relatively rotate, the driving mechanism and feeding mechanism bottom are equipped with supporting leg.
Further, the driving mechanism includes driving motor and planetary gear set, the planetary gear set include gear ring, Planetary gear and sun gear, the driving motor output end are fixedly connected with sun gear center, the sun wheel end and inner cylinder end Portion is fixedly connected, and the gear ring end is fixedly connected with outer cylinder end, and the gear ring outer surface is arranged with bearing, the bearing with Supporting leg is fixedly connected.
Further, the feeding mechanism is auger charger.
Further, the feed end of the inner barrel and outer barrel is installed with concentric support tube one and support tube two, institute respectively It states auger charger to protrude into inside support tube one, cylindrical support member is provided on the supporting leg, is opened inside cylindrical support member There is stairstepping through-hole, the stairstepping through-hole is greater than other end diameter, the support tube close to one end diameter of ball mill ontology One is connect with stairstepping through-hole small end by bearing, and support tube two is connect with stairstepping through-hole big end by bearing, passes through cylinder Shape supporting element is supported inner barrel and outer barrel, guarantees entire ball mill stability.
Further, the sieve material mouth and discharge port are uniformly distributed rotating around ball inner cylinder center wire loop, and this is done so that ores in sand form Discharge uniformly, prevents from blocking, and then improves mill efficiency.
At work, driving motor drives sun gear rotation to the twin-stage ball mill of the utility model, thus driving and the sun The inner cylinder rotation being fixedly connected is taken turns, the preliminary grinding of grinding ore progress is treated in the ball rolling that rolls in inner cylinder, primary ore in sand form is obtained, Mine sand is leaked out as inner cylinder is constantly rotated from bottom sieve material mouth, and the ore in sand form leaked out from sieve material mouth includes qualified ore in sand form, directly from Discharge port leaks out collection and unqualified ore in sand form, is stopped by discharge port, and secondary grinding is received, and sun gear drives while rotation Planetary gear rotation, planetary gear drive ring gear against rotation again, thus the outer cylinder rotation that driving is fixedly connected with gear ring, due to planet crop rotation With, inner barrel and outer barrel rotation direction on the contrary, and inner cylinder speed be greater than outer cylinder speed, pressure roller and outer tube inner wall are acted on to not on inner cylinder Qualified ore in sand form carries out secondary grinding, obtains qualified ore in sand form and collection is discharged from discharge port again.
The beneficial effects of the utility model are as follows:
1. the utility model carries out grinding to ore by setting two-stage grinding mechanism, in time by the unqualified of smaller particle size Inner cylinder is discharged in ore in sand form, and secondary grinding is carried out between pressure roller and outer wall and to qualification and is discharged, can only be arranged compared to conventional bead mill Qualified ore in sand form out can be present in roll to avoid the unqualified ore in sand form of smaller particle size and play protection work to big granularity ore in sand form between ball With raising mill efficiency.
2. the utility model is by setting planetary gear set, so that inner cylinder and outer cylinder rotation direction are on the contrary, and inner cylinder speed Degree is greater than outer cylinder speed, enables the unqualified ore in sand form of smaller particle size between pressure roller and outer wall by grinding, grinding effect is more Good, and since outer cylinder is not stalling dynamic, when discharge port turns to top, ore in sand form is easy discharge in time, and qualified ore in sand form will not be due to Pressure roller squeezes and long time sedimentation avoids blocking in bottom.
3. stepped sleeve is connect with support tube one and support tube two by bearing respectively, and by supporting leg, and supporting Auger charger is set in cylinder one, can be realized ball mill and do not shut down charging, improve mill efficiency.
