Examples

As shown in fig. 1-4, an efficient barite grinding device comprises a shell 1, wherein a funnel-shaped feeding port 2 is arranged at the top of the shell 1, a funnel-shaped discharging port 3 is arranged at the bottom of the shell 1, a material conveying port 4 is arranged on the side wall of the shell 1, and a crushing device 5, a screen 6 and a grinding device are sequentially arranged in the shell 1 from top to bottom.

Specifically, the crushing device 5 comprises three crushing rollers which are longitudinally fixed with the shell 1 through connecting columns at two ends of the crushing rollers, namely the connecting columns are fixed between the front side wall and the rear side wall of the shell 1 and are integrally formed with the crushing rollers. The whole crushing device 5 is an inverted equilateral triangle, the surfaces of the first crushing roller and the second crushing roller are provided with crushing teeth 51 along the axial direction, the first crushing roller and the second crushing roller are both positioned above the third crushing roller, and the first crushing roller and the second crushing roller are equal in height. Wherein the one end spliced pole of first crushing roller and second crushing roller all is connected with the motor, and the motor passes through mounting such as bolt to be installed at the lateral wall of casing 1, and the motor circular telegram rotates the back, can drive first, two crushing rollers through its output shaft and rotate, and first, two crushing rollers are the rotation in opposite directions. Through the rotation of first, two crushing rollers, can carry out the breakage with the barite that gets into through the feed inlet, the barite after the breakage can drop at the outer wall of third crushing roller, simultaneously because the outer wall of third crushing roller is the cambered surface setting, fast descending barite piece can be respectively to its both ends landing, so because last pivoted first, two crushing rollers, then can carry out the secondary breakage to descending barite piece respectively, so, in order to improve the degree of breakage of barite piece, guaranteed going on smoothly of follow-up grinding work.

Furthermore, the bottom of the crushing device 5 is provided with a screen 6, the screen 6 is obliquely arranged, the lower end of the screen is fixed with the side wall of the material conveying opening 4 on the side wall of the shell 1, and the outer part of the material conveying opening 4 is connected with a conveying channel 7. So, the barite piece after the breakage can directly drop on screen cloth 6 under the effect of gravity, and the barite piece that is less than 6 holes of screen cloth then drops to below grinder through the mesh and grinds, and the barite piece that is greater than 6 holes of screen cloth then can stay on screen cloth 6 and roll into along with the screen cloth 6 that the slope set up with defeated material mouth 4 in the transmission path 7 of being connected.

Further, the transmission channel 7 is connected with a particle elevator 8, the large-particle barite can be transmitted from the material conveying port 4 to an inlet of the particle elevator 8 through the transmission channel 7, and an outlet of the particle elevator 8 can be connected with a feeding port of the grinding mill through a pipeline. After the crushing is completed, the worker can lift the large-grained barite mass discharged through the material discharge opening 4 again by the particle lifter 8 and transfer the large-grained barite mass into the material discharge opening of the housing 1. Then the large-particle barite mass can be re-introduced into the crushing device 5 for re-crushing to increase the degree of crushing of the barite so that more barite can fall from the screen 6 into the grinding device. The elevator adopts the existing spiral feeding elevator, and the equipment can be directly purchased in the market or on the Internet, so that the specific structure of the equipment is not described too much.

Further, screen cloth 6 below is equipped with hopper-shaped material receiving channel 61, and the top that receives material channel 61 is fixed with screen cloth 6's bottom respectively, and the discharge end that receives material channel 61 sets up on grinder's top, so, through receiving material channel 61, can make the barite piece that drops from screen cloth 6 each department concentrate and fall into below grinder to grind.

The grinding device comprises two opposite rotating rollers 9, the side walls of the rollers 9 are close to each other, and the funnel-shaped discharge hole 3 is formed below the rollers 9. The roller 9 is also longitudinally fixed in the casing 1, namely, the guide rods 91 which are arranged at two ends of the roller and are integrally formed with the roller are respectively fixed with the front side wall and the rear side wall of the casing 1, the guide rod 91 at one end is connected with a motor, the motor is arranged on the side wall of the casing 1 through fixing parts such as bolts, and the motor provides rotating power for the motor after being electrified. By the opposite rotation of the two rollers 9, the small-particle barite entering the grinding device can be ground. Along with the continuous rotation of roller bearing 9, the barite powder that grinds can directly drop into business turn over material mouth 3 because of the reason of gravity to outside staff can concentrate and carry out subsequent processing to the barite powder.

Further, be equipped with a plurality of recesses 11 on the lateral wall of casing 1, the inner wall of recess 11 inlays and is equipped with bearing 12, and the crushing roller can stretch into in recess 11 with the other end spliced pole of roller bearing 9 not connected motor and guide arm 91, and cup joint in bearing 12, so fixed the position of crushing roller and roller bearing 9 in casing 1, and still can avoid crushing roller and roller bearing 9 to bring the influence to whole casing 1 when the pivoted.

Further, since the barite is subjected to the steps of washing and drying before being crushed, but after the barite is crushed, the inside of the barite is likely to be incompletely dried, and then after the barite is ground into powder, the barite with moisture is adhered into a cake shape, which is not beneficial to the later collection and storage of the barite powder. Therefore the utility model discloses a roller bearing 9 is hollow setting rather than guide arm 91, and guide arm 91 is the unclosed barrel, and the 11 lateral walls departments of recess at guide arm 91 place are equipped with through-hole 13, and through-hole 13 department is fixed with hot-blast main 14 through solid fixed ring 15, and hot-blast main 14 connects outside hot-blast source. The part of the hot air pipe 14 extending into the shell 1 can continue to extend into the guide rod 91 to send hot air into the roller 9, so that the roller 9 has heat, and the roller 9 with heat can dry crushed barite to a certain extent while grinding, so as to avoid the defect that the barite powder is stuck into a cake shape after grinding. The hot air source can be any existing machine capable of outputting hot air, such as a burner, and therefore, the specific structure of the hot air source is not described too much.

Parts not described in the above modes can be realized by adopting or referring to the prior art.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing embodiments, or equivalents may be substituted for elements thereof. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
