[0028] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation mode, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0029] like Figure 1-2 , Figure 8As shown, a ball mill granulator includes a roller 1, a driving device for driving the roller 1 and a supporting device for supporting the driving device. A feed port 2 is arranged at one end of the roller 1, and a discharge port 3 is arranged at the other end. The driving device includes a driving shaft 9, a driven shaft 12 and a driving mechanism connected to the driving shaft 9. The driving mechanism includes a transmission belt 11 and a reduction motor 10. The reduction motor 10 is connected to the driving shaft 9 through the transmission belt 11. The transmission belt 11 is provided with convex patterns to match the driving shaft 9 for better transmission.

[0030] The supporting device includes a base 6 and a first supporting member 5, a second supporting member 13, a fixed supporting frame 8, and a bidirectional supporting roller body located on the base 6. Both ends of the driving shaft 9 are rotatably arranged on the first supporting member 5 on one side of the bottom of the roller 1, and both ends of the two driven shafts 12 are rotatably arranged on the second supporting member 13 on the other side of the bottom of the roller 1. A plurality of rolling wheels 7 are fixedly installed at intervals on the driving shaft 9 and the driven shaft 12. The rolling wheels 7 are transmission-connected to the roller 1. The rolling wheels 7 are fixedly installed on the driving shaft 9 and the driven shaft 12 in groups of two at intervals. The fixed supporting frame 8 is rotatably installed between each group of adjacent rolling wheels 7 on the driving shaft 9. The cam 14 is arranged between each group of adjacent rolling wheels 7 on the driven shaft 12. The bidirectional supporting roller body is arranged at the bottom of the cam 14 and is transmission-connected to the cam 14. The rolling wheels 7 use a group of two to more stably roll the roller 1.

[0031] Each group of rolling wheels 7 are arranged on the driving shaft 9 and the driven shaft 12 in descending order with different outer diameters, and the rollers 1 are arranged on the rolling wheels 7 with different outer diameters from the feed port 2 to the discharge port 3 from high to low, and the inclination angle between the central axis of the roller 1 and the horizontal plane is 5°.

[0032] The driven shaft 12 is composed of two individuals of the same length that are disconnected in the middle. Both ends of the two driven shafts 12 are coaxially arranged on the second support member 13 on the same side of the roller 1. Using two identical sections of the driven shaft 12 prevents the driven shaft 12 from being too long and increasing the risk of breakage.

[0033] like Figure 2 , Figure 4-7As shown, the bidirectional support roller body includes two support rollers 15, two bearing brackets 16 and a base frame 17. The base frame 17 is arranged on the base 6. The two support rollers 15 are rotatably installed in the two bearing brackets 16 respectively. The bearing bracket 16 is arranged on the base frame 17. The two support rollers 15 and the bearing bracket 16 are symmetrically arranged on the base frame 17. The two sides of the bottom of the cam 14 are transmission-connected to the support rollers 15. A through groove 21 is provided on the surface of the base frame 17. The two ends of the base frame 17 are fixedly connected to the fixing blocks 18. A first bolt 19 is connected to the bearing bracket 16. The first bolt 19 passes through the through groove 21 and cooperates with the bottom nut to fix the bearing bracket 16 on the base frame 17. A screw hole and a second bolt 20 matching the screw hole thread are provided on the fixing block 18. The second bolt 20 passes through the screw hole of the fixing block 18 and conflicts with the bearing bracket 16. The second bolt 20 is limited and fixed by the second bolts 20 on the fixing blocks 18 at both ends of the base frame 17 so that the bearing brackets 16 on both sides will not loosen or move.

[0034] The supporting roller 15 is a GCr15 high-strength alloy steel roller assembly, and the bearing bracket 16 is a heavy-duty bearing bracket. The supporting roller is made of super wear-resistant material and the heavy-duty bearing bracket has a longer service life and is more durable.

[0035] like Figure 1 As shown, the fixed support frame 8 includes a shell, a bearing and a bracket. The bearing is arranged in the shell, and the bearing sleeve is arranged on the driving shaft 9 and is rotatably connected to the driving shaft 9. The shell is arranged on the bracket, and the bracket is arranged on the base 6. The driving shaft 9 adopts a fixed support frame 8 with higher concentricity and stronger auxiliary support ability.

[0036] like Figure 3 As shown, an anti-skid ring sleeve 4 is installed on the outer wall of the roller 1, and a third support member 23 is provided on the base 6. The third support member 23 is located below the anti-skid ring sleeve 4. The third support member 23 is rotatably connected to the anti-skid roller 22, and the anti-skid roller 22 is transmission-connected to the anti-skid ring sleeve 4 to prevent the roller 1 from sliding and displacing due to the tilted setting.

[0037] Working principle:

[0038] After the processed material enters the roller 1 from the feed port 2, the reduction motor 10 is started, and the transmission belt 11 drives the driving shaft 9 to rotate under the support of the first support member 5 and the fixed support frame 8. The rolling wheel 7 on the driving shaft 9 rotates synchronously, and the rolling wheel 7 drives the roller 1 to rotate. The rolling wheels 7 on the two driven shafts 12 on the other side of the roller 1 rotate with the roller 1, thereby driving the two driven shafts 12 to rotate on the second support member 13, and the cam 14 on the driven shaft 12 rotates synchronously, driving the supporting rollers 15 on both sides of the bottom of the cam 14 to rotate on the bearing bracket 16. After being decomposed and crushed, the raw materials are turned out from the inclined roller discharge port 3;

[0039] When the supporting rollers 15 on both sides of the bottom of the cam 14 have a gap with the cam 14 and the transmission support is loose, the nuts of the first bolts 19 in the through grooves 21 of the base frame 17 are unscrewed, so that the bearing bracket 16 can slide above the through grooves 21 of the base frame 17, and then the second bolts 20 in the fixing blocks 18 at both ends of the base frame 17 are tightened, so that the bottom of the second bolts 20 pushes the bearing brackets 16 on both sides to move inward and closely contact the two sides of the bottom of the cam 14 for limited fixing, and then the nuts at the bottom of the first bolts 19 are screwed on to fix the bearing bracket 16; by arranging the fixed support frame 8 on the driving shaft 9, the concentricity is higher and the auxiliary support capacity is stronger; by adding an adjustable two-way supporting roller body at the middle position of the two sections of the driven shaft 12, the supporting roller 15 is synchronously supported and rotated when the driven shaft 12 is running, and the driven shaft 12 will not break due to the impact creep fatigue of the processed material in the ball mill after being supported in the middle part, and there is no power demand, simple adjustment, convenient maintenance, more stable production operation and long service life.
