Detailed Description

The following detailed description of the present invention will be made with reference to the accompanying drawings and examples.

As shown in the accompanying drawing 1, the utility model discloses a barite milling machine structure, including casing 1, feed inlet 7 has been seted up on 1 one side upper portion of casing, feed inlet 7 connects the hopper (set up subaerially, not shown on the picture) through loading attachment (not shown on the picture), is equipped with crocus mechanism in the casing 1, crocus mechanism below sets up shale shaker 2, the discharge gate flexible coupling of crocus mechanism the feed inlet 7 of shale shaker 2, the coarse fodder export 21 of shale shaker 2 are connected the hopper.

In the use, drop into the barite granule from feed inlet 7, the granule is through grinding polishing of milling machine structure, then gets into shale shaker 2, and the large granule barite that does not conform to the requirement gets back to the hopper of splendid attire barite raw materials again through the coarse fodder export 21 of shale shaker 2 in to feed inlet 7 is come under loading attachment's effect, circulates and polishes, meets the requirements up to the granule size.

According to some embodiments of the invention, the milling mechanism comprises a first milling assembly and a second milling assembly.

According to some embodiments of the utility model, first crocus subassembly includes first motor 31, door form turret 8 and annular grinding roller 5, wherein, annular grinding roller 5 is fixed in two tip of turret 8, the pivot of first motor 31 sets up down, the central point at 8 tops of turret is rotatory through first motor 31 drive, thereby drives annular grinding roller 5 uses first motor 31 pivot to rotate as the axle center, annular grinding roller 5 outer ring with form first crocus passageway 41 between the casing 1 inner wall. The turret 8 may also have a plurality of end portions which form a cylinder-like shape and which are more stable when fixedly connected to the ring-shaped grating roller 5.

According to some embodiments of the utility model, the second crocus subassembly include second motor 32 and by second motor 32 driven center grinding roller 6, center grinding roller 6 with annular grinding roller 5 coaxial setting, annular grinding roller 5 inner ring with form second crocus passageway 42 between the center grinding roller 6. Both the first motor 31 and the second motor 32 may be fixed to an inner wall of the housing 1, and dust covers may be provided outside the first motor 31 and the second motor 32.

According to some embodiments of the present invention, the inner ring diameter of the ring-shaped grinding roller 5 gradually decreases from top to bottom, the diameter of the central grinding roller 6 gradually decreases from top to bottom, and the distance between the ring-shaped grinding roller 5 and the central grinding roller 6 gradually decreases from top to bottom.

According to some embodiments of the utility model, 5 inner rings of annular grinding roller and outer loop 1 inner wall of casing and evenly distributed has the arch of polishing 9 on the central grinding roller 6. The grinding projection 9 may be a hemisphere as shown in fig. 1, or may be other shapes such as a cylinder.

According to some embodiments of the present invention, a material guiding plate 10 is disposed in the housing 1 below the milling mechanism.

As shown in fig. 1, the inlet of the first milling path 41 is smaller than the inlet of the second milling path 42, and since the first milling path 41 is closer to the feed opening 7, the barite particles will first pass through the first milling path 41 when entering the interior of the housing 1, and larger particles will not enter the first milling path 41 and will move to the second milling path 42 during the grinding process. The smaller particles are directed into the first milling path 41 for grinding. After the larger particles enter the second milling passage 42, the larger particles gradually become smaller particles along with the continuous grinding, and finally fall onto the guide plate from the outlet of the second milling passage 42 and finally enter the vibrating screen 2. To enhance the grinding effect, the central grinding roller 6 and the annular grinding roller 5 rotate in opposite directions.

According to some embodiments of the invention, the feeding device is a screw feeder. The screw feeder is inclined to lift the barite material in the hopper above ground to the feed inlet 7 on the housing 1.

According to some embodiments of the present invention, the fines outlet 22 of the vibrating screen 2 is connected to a storage silo. The storage bin is used for storing the ground barite powder for use.

Finally, although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the present invention can be modified or replaced by other means without departing from the spirit and scope of the present invention, which should be construed as limited only by the appended claims.
