Preferably, the fixing frame comprises two layers of concentric circle frames positioned on the same plane, and eight fixing rods which are positioned on the same plane with the concentric circle frames and are perpendicular to the concentric circle frames are arranged between the two layers of concentric circle frames; each group of fixing rods corresponds to the partition plate in position; every two groups of adjacent fixed rods separate the areas between two layers of concentric rings to form the slotted hole.
Preferably, the fixing ring is provided with a convex connecting ring which is clamped with the inner ring of the concentric ring frame.
Preferably, the connecting ring is fixedly provided with a first handle for placing and lifting the separation frame; the concentric circle frame is fixedly provided with a second handle for placing and lifting the fixing frame.
Preferably, protruding inserting blocks are fixedly arranged on the outer peripheral surface of the connecting ring, and inserting grooves are formed in the inner peripheral surface of the concentric ring frame corresponding to the inserting blocks.
Preferably, the partition plate is a long conical column with concave vertical surfaces at two sides, and the conical head direction of the long conical column is far away from the partition frame.
The beneficial effects are that: ① The accurate positioning of the grinding balls is achieved through the positioning device formed by the separation frame and the fixing frame, so that the positions of the grinding balls are kept fixed in each grinding process; ② Because coal sample particles are tiny, but in grinding test, need sweep coal sample particles to the grinding region, promptly grind between ball and the grinding bowl inner wall, through demountable installation's separation frame and mount, realize still can realize that the coal sample cleans after positioner installs.

Detailed Description
The technical scheme of the application is further described below with reference to the accompanying drawings.
As shown in fig. 1 to 4, the specific structure in the following embodiment is as follows:
the whole positioning device is made of galvanized iron and consists of a separation frame 1 and a fixing frame 2, wherein a convex connecting ring 8 is arranged on the fixing frame 2, and the connecting ring 8 is clamped with the inner ring of a concentric ring frame 6; and the outer peripheral surface of the connecting ring 8 is fixedly provided with a convex inserting block 11, the inner peripheral surface of the concentric ring frame 6 is provided with a slot 12 corresponding to the inserting block 11, and the fixing frame 2 is clamped with the inserting block 11 of the separation frame 1 through the slot 12 to form a complete positioning device.
The separation frame 1 comprises a fixed ring 3 and eight separation plates 4 which encircle the bottom of the fixed ring 3 and are uniformly and vertically fixed; the height of the partition plates 4 is lower than the diameter of the grinding balls in the grinding bowl, so that the partition frame 1 can be placed along the protrusions in the grinding bowl to separate eight grinding balls, and every two adjacent partition plates 4 form a bin for accommodating the grinding balls; the fixing frame 2 is detachably connected above the separation frame 1.
The fixing frame 2 comprises two layers of concentric circle frames 6 positioned on the same plane, and eight fixing rods 7 which are positioned on the same plane with the concentric circle frames 6 and are perpendicular to the concentric circle frames 6 are arranged between the two layers of concentric circle frames 6; each group of fixing rods 7 corresponds to the partition plate 4 in position; every two groups of adjacent fixed rods 7 separate the areas between the two layers of concentric ring frames 6 to form slotted holes 5.
In the state that the fixing frame 2 is detachably connected with the separation frame, the height difference between the lower bottom surface of the slotted hole 5 and the lower bottom surface of the separation frame 1 is 0.85-0.95 times of the diameter of the grinding ball, the diameter of the grinding ball actually used is 6cm, and the height difference is 5.4cm; each grinding ball is fixed in the slot 5 of the corresponding bin by the height difference, so that the grinding ball is fixed.
The connecting ring 8 is fixedly provided with a first handle 9 for placing and lifting the separation frame 1; the concentric circle frame 6 is fixedly provided with a second handle 10 for placing and lifting the fixing frame 2. The partition plate 4 is specifically structured as a long conical column with concave vertical surfaces at two sides, and the conical head direction of the long conical column is far away from the partition frame 1.
The specific use mode is as follows:
As shown in FIG. 5, 8 grinding balls are placed in a grinding bowl, a separation frame 1 is placed from a concave position in the grinding bowl to ensure that each grinding ball is separated, the position of the grinding ball is slightly adjusted to be centered, a fixing frame 2 is placed, after the position of the grinding ball is completely fixed, a prepared coal sample is added, and a brush is used for uniformly sweeping the coal sample to one side of the grinding ball close to the inner wall of the grinding bowl. And then the fixing frame 2 is taken down, at the moment, the gaps between the grinding balls are filled with the coal sample, and the ball positions are also fixed by the sample. And then the sample is carefully and uniformly swept into an area consisting of the front end of the long conical partition plate 4, the grinding balls and the inner wall of the grinding bowl by using a brush, so that the sample is ensured to be uniformly distributed and fills the area, and finally the partition frame 1 is taken out, and the final leveling of the coal sample is realized for Hardgkin grindability measurement.
After the implementation measures are adopted, the distribution positions of the sample and the grinding ball are basically consistent during each grinding, so that the working condition of the sample during grinding is basically consistent, and the accuracy of an analysis result is improved.
