Abstract
The utility model discloses a kind of ball mill, comprise the cylinder of horizontally set, support the pivotal supporting seat of described cylinder and drive the pivotal drive unit of described cylinder, the inside of described cylinder is provided with multiple metal ball body, also comprise pressing close to the curved baffle that described inner wall of rotary drum is arranged, described baffle plate middle and upper part and the distance between inner wall of rotary drum keep substantially identical with the external diameter of described metal ball body, the top of described baffle plate is near the inside top of cylinder, and the bottom of described baffle plate is near the middle and lower part of described inner wall of rotary drum.Ball mill of the present utility model is by arranging curved baffle, even if make cylinder under rotating speed slowly, namely steel ball solves existing drum's speed of rotation requirement strict, the problem that crush efficiency is low under throwing after still can moving to the top of drum inside.
Description
Technical field
The utility model relates to a kind of plant equipment, particularly relates to a kind of ball mill.
Background technology
Ball mill is primarily of parts compositions such as cylindrical tube, end cap, bearing and transmission bull gears, steel ball or rod iron that diameter is 25-150mm is loaded in cylindrical shell, be called that mill is situated between, its charge weight is the 25%-50% of whole cylindrical shell volume, in drive system, motor drives large gear ring and cylindrical shell by shaft coupling, decelerator and pinion, slowly rotates.When barrel body rotation, mill be situated between rises to certain altitude with cylinder, then parabolically fall or rush down and under.The shortcoming of existing ball mill is: when drum speed overflows, and steel ball cannot be thrown, and does not have the effect of pulverizing, and when rotating speed is fast, steel ball easily under centrifugal action, is close to inner barrel and cylindrical body synchronous rotates, and does not also have pulverization.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of ball mill, and the advantage of this ball mill is no matter drum speed is high or low, can be under throwing after steel ball moves to drums inside top, solve existing drum's speed of rotation requirement strict, the problem that crush efficiency is low.
The utility model is solved the problem by following technological means:
Ball mill of the present utility model, comprise the cylinder of horizontally set, support the pivotal supporting seat of described cylinder and drive the pivotal drive unit of described cylinder, the inside of described cylinder is provided with multiple metal ball body, also comprise pressing close to the curved baffle that described inner wall of rotary drum is arranged, described baffle plate middle and upper part and the distance between inner wall of rotary drum keep substantially identical with the external diameter of described metal ball body, the top of described baffle plate is near the inside top of cylinder, and the bottom of described baffle plate is near the middle and lower part of described inner wall of rotary drum.
Further, described baffle plate bottom bends to the direction away from drums inside.
Further, the two ends of described cylinder are each is coaxially interspersed with a fixing cylindricality body of rod, and the two ends, left and right of described baffle plate are fixedly connected with the described cylindricality body of rod by the circular plate body being embedded into drum inside end face.
The beneficial effects of the utility model: ball mill of the present utility model, comprise the cylinder of horizontally set, support the pivotal supporting seat of described cylinder and drive the pivotal drive unit of described cylinder, the inside of described cylinder is provided with multiple metal ball body, also comprise pressing close to the curved baffle that described inner wall of rotary drum is arranged, described baffle plate middle and upper part and the distance between inner wall of rotary drum keep substantially identical with the external diameter of described metal ball body, the top of described baffle plate is near the inside top of cylinder, and the bottom of described baffle plate is near the middle and lower part of described inner wall of rotary drum.Ball mill of the present utility model is by arranging curved baffle, even if make cylinder under rotating speed slowly, namely steel ball solves existing drum's speed of rotation requirement strict, the problem that crush efficiency is low under throwing after still can moving to the top of drum inside.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further described.
Fig. 1 is the perspective view of the utility model ball mill;
Fig. 2 is the internal structure schematic diagram of the utility model ball mill intermediate roll.
Detailed description of the invention
Below with reference to accompanying drawing, the utility model is described in detail:
As illustrated in fig. 1 and 2, ball mill in the present embodiment, comprise the cylinder 1 of horizontally set, support the pivotal supporting seat of described cylinder 12 and drive the pivotal drive unit 3 of described cylinder, particularly, as adopted in the present embodiment, mode that hollow rotating shaft matches with the supporting seat 2 comprising bearing and bearing block is set in body both ends of the surface and forms effective support to cylinder, the inside of described cylinder 1 is provided with multiple metal ball body 4, also comprise pressing close to the curved baffle 5 that described cylinder 1 inwall is arranged, described baffle plate 5 middle and upper part and the distance between cylinder 1 inwall keep substantially identical with the external diameter of described metal ball body 4, the top of described baffle plate 5 is near the inside top of cylinder 1, the bottom of described baffle plate 5 is near the middle and lower part of described cylinder 1 inwall, particularly, the two ends of described cylinder 1 are each is coaxially interspersed with a fixing cylindricality body of rod 6, the two ends, left and right of described baffle plate 5 are fixedly connected with the described cylindricality body of rod 6 by the circular plate body 7 being embedded into drum inside end face.During work, when being full of material bottom drum inside, and drum rotation speed slower time, mobility will be reduced between multiple metal ball body 4, therefore metal ball body 4 can be passed through between baffle plate 5 and cylinder 1 inwall successively under the promotion of sluggish power, until carry out broken material from eminence whereabouts with the impact of height when moving to baffle plate 5 top.
As the further improvement of technique scheme, described baffle plate 5 bottom bends to the direction away from cylinder 1 inside, so that by squeezing action, metal ball body is easily entered between baffle plate and cylinder 1 inwall.
What finally illustrate is, above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, although be described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify to the technical solution of the utility model or equivalent replacement, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of right of the present utility model.
