Description
Technical field
It the utility model is related to a kind of ball mill device, particularly a kind of ball mill for low-grade antimony ore ore dressing.
Background technology
Ball mill is the key equipment that material is broken and then crushed, and is using floatation to low-grade antimony ore
During carrying out ore dressing, the antimony ore after crushing is milled using ball mill, for follow-up flotation operation.Ball milling
During, antimony ore, water and abrasive body after usually crushing, which are together added in the sand cylinder of ball mill, to be ground, and is ground
Body is generally steel ball, and when ball mill grinding cylinder rotates, abrasive body is due to the work of inertia, centrifugal action and frictional force
With, it is attached on shell liner and taken away by cylinder, when certain height is brought to, due to itself Action of Gravity Field and
Left, the abrasive body of whereabouts is smashed the material in cylinder as projectile, and bang and abrasive action are produced to material.
When being ground to antimony ore, the granular size of antimony ore grinding depends primarily on water, abrasive body diameter and abrasive body addition,
Existing ball mill is mostly monotubular structure, and after antimony ore is added in sand cylinder, the grinding situation of antimony ore is difficult to monitor, antimony after grinding
Ore deposit grain diameter is uneven, and grinding effect is poor, also needs to do over again；And the ball mill of monotubular structure can only once enter to a collection of antimony ore
Row grinding, could add next group antimony ore after the completion of grinding, due to being difficult to that grinding situation is detected, then when needing to extend grinding
Between to ensure the quality of grinding, processing efficiency is slower.Therefore, when existing ball mill is ground to antimony ore, the antimony ore of grinding
Grain diameter is uneven, and grinding effect is poor, and milling time is longer, and processing efficiency is relatively low.
The content of the invention
The purpose of this utility model is, there is provided a kind of ball mill for low-grade antimony ore ore dressing.The utility model exists
When being ground to antimony ore, it can be screened automatically, the antimony ore grain diameter not only ground is uniform, and grinding effect is preferable, and then
The quality of low-grade antimony ore flotation beneficiation is improved, and can use and not shut down processing mode, processing efficiency is higher.
The technical solution of the utility model：A kind of ball mill for low-grade antimony ore ore dressing, including cabinet, set in cabinet
There is corase grind cylinder, corase grind cylinder is connected by screening connection road with fine grinding cylinder, and screening grid, screening connection road are provided with screening connection road
Top is additionally provided with steel ball addition road；Cabinet side is provided with the feeding channel being connected with corase grind cylinder, and cabinet opposite side is provided with and fine grinding
The tapping channel of cylinder connection, flow-limiting valve is provided with the tapping channel, roughly grinds cylinder and fine grinding cylinder is peripheral is provided with one group of driving rack,
Motor is additionally provided with above cabinet, motor is provided with drive gear, and drive gear engages with driving rack, the cabinet
Lower section is provided with prop, and prop is provided with the support gear with driving rack aligned in position.
In a kind of foregoing ball mill for low-grade antimony ore ore dressing, corase grind liner plate is provided with the corase grind cylinder.
In a kind of foregoing ball mill for low-grade antimony ore ore dressing, fine grinding liner plate is provided with the fine grinding cylinder.
Compared with prior art, by setting corase grind cylinder and fine grinding cylinder, using attrition process twice, antimony ore grinding effect is improved
Fruit；Installation screening grid in road is connected by the screening set between corase grind cylinder and fine grinding cylinder, according to the particle diameter of antimony ore particle
Size passes through to carry out selection, and the antimony ore particle of different-grain diameter size is separated, and not only improves grinding quality, and improve processing
Efficiency；By setting steel ball to add road above screening connection road, can further be carried ground into middle supplement addition abrasive body
High grinding effect；By using the means of screening separation, the antimony ore of big particle diameter is stayed in corase grind cylinder and grind, the antimony ore of small particle
With water automatically into being ground in fine grinding cylinder, overflowed after reaching tapping channel with water flowing, whole inlet/outlet process is not required to
Shutdown operation, processing efficiency are higher.In summary, the utility model can be screened, no automatically when being ground to antimony ore
The antimony ore grain diameter only ground is uniform, and grinding effect is preferable, and then improves the quality of low-grade antimony ore flotation beneficiation, Er Qieke
Using processing mode is not shut down, processing efficiency is higher.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
