[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] like Figure 1-4 As shown, a ball mill comprises a plurality of conical material outlets 1, the top ends of the plurality of conical material outlets 1 are fixedly connected to fixed frames 2 near the front and rear ends, and a ball mill barrel 4 is rotatably mounted on the top end of the fixed frame 2 through a hollow feed shaft 3;

[0023] A discharge port is provided at the bottom end of the ball mill barrel 4, and an adjustment component 7 is provided at the top end of the ball mill barrel 4. The adjustment component 7 includes an adjustment drum 8. A mounting groove matching the adjustment drum 8 is provided inside the ball mill barrel 4. The adjustment drum 8 is rotatably installed in the mounting groove. A filter mesh port 12 is provided through the top end of the adjustment drum 8, and a discharge port 13 is provided through the bottom end of the adjustment drum 8, and the filter mesh port 12 and the discharge port 13 match the feed port.

[0024] In this embodiment, a driven gear 9 is fixedly connected to the rear position of the outer ring of the adjusting drum 8, an adjusting motor 10 is installed at the rear position of the top end of the ball mill drum 4, a driving gear 11 is installed at the end of the driving shaft of the adjusting motor 10, and the driving gear 11 is meshed and matched with the driven gear 9. By rotating the driving shaft of the adjusting motor 10, the meshing transmission drives the adjusting drum 8 to rotate, which is convenient for adjustment.

[0025] In this embodiment, the outer ring of the adjusting drum 8 fits with the inner ring of the mounting groove, and the adjusting drum 8 is meshedly connected with the driving shaft of the adjusting motor 10 through the driven gear 9 and the driving gear 11, and the adjusting motor 10 does not contact the top surface of the tapered blanking port 1. By fitting the outer ring of the adjusting drum 8 with the inner ring of the mounting groove, it is convenient to improve the sealing performance and the rotation stability of the adjusting drum 8. When the discharge port 13 and the filter screen port 12 at the adjusting drum 8 have not rotated to the discharge port of the ball mill barrel 4, the discharge port of the ball mill barrel 4 is blocked to prevent the raw material from leaking. At the same time, the adjusting motor 10 and the tapered blanking port 1 do not contact each other, so as to avoid the adjustment motor 10 from colliding with the tapered blanking port 1 during the rotation process and causing damage.

[0026] In this embodiment, a driving motor 5 is installed at the front top of the fixed frame 2, and a transmission wheel group 6 is installed at the lower inside of the fixed frame 2. The driving shaft of the driving motor 5 is connected to the ball mill barrel 4 through the transmission wheel group 6. By starting the driving motor 5, the driving shaft of the driving motor 5 rotates to drive the transmission wheel group 6 to rotate, thereby driving the grinding balls and raw materials in the ball mill to rotate, which is convenient for grinding the raw materials.

[0027] In this embodiment, a plurality of conical drop openings 1 are in the same straight line and are arranged equidistantly. A mounting frame 14 is installed at a lower position inside the conical drop opening 1. A conveyor belt 15 is installed inside the mounting frame 14 through a rotating shaft. The conical drop opening 1 is set to facilitate guiding the raw materials. The conveyor belt 15 plays a role in lifting the raw materials, which is convenient for subsequent centralized discharge.

[0028] In this embodiment, a conveying motor is installed at the rear position of one side of the mounting frame 14, and the driving shaft of the conveying motor is connected to the rotating shaft of the conveyor belt 15. The conveying motor driving shaft rotates to drive the conveyor belt 15 to convey the raw materials, thereby facilitating the transportation of the raw materials.

[0029] It should be noted that the utility model is a ball mill. When in use, first, the foam glass raw material can be added into the ball mill barrel 4 from the feeding hollow shaft 3 as needed, and then the feeding hollow shaft 3 is closed, and the driving motor 5 is started as needed. Since the driving shaft of the driving motor 5 is connected to the ball mill barrel 4 through the transmission wheel group 6, the driving shaft of the driving motor 5 can drive the transmission wheel group 6 to rotate, thereby driving the grinding balls in the ball mill and the raw materials to rotate for grinding;

[0030] When the grinding is completed, the driving motor 5 can be controlled to rotate, and the discharge port of the ball mill barrel 4 can be adjusted downward, and then the adjusting motor 10 can be started. Since the adjusting motor 10 is meshed and connected with the adjusting drum 8 through the driving gear 11 and the driven gear 9, and the adjusting drum 8 is rotatably installed in the ball mill barrel 4, the adjusting drum 8 plays the role of blocking the discharge port, and the adjusting drum 8 is provided with a discharge port 13 and a filter screen port 12;

[0031] When it is necessary to filter and discharge the material, the drive shaft of the regulating motor 10 can be rotated to adjust the regulating drum 8 to rotate, and the filter mesh port 12 at the regulating drum 8 is aligned with the discharge port of the ball mill barrel 4. After that, the raw material is filtered through the filter mesh port 12 and falls into the conical discharge port 1, and slides down from the conical discharge port 1 and falls onto the conveyor belt 15. Then, the conveying motor can be started as needed. Since the drive shaft of the conveying motor is connected to the rotating shaft of the conveyor belt 15, the conveying motor drive shaft can be rotated to drive the conveyor belt 15 to transport the raw material, and the discharge process is completed. In addition, multiple ball mill barrels 4 are installed in parallel, and the conveyor belt 15 is arranged under multiple ball mill barrels 4. According to the above steps, multiple ball mill barrels 4 can be discharged simultaneously;

[0032] At the same time, when filtering and discharging are not required, the above steps can be followed to control and adjust the rotation of the drum 8, and the discharge port 13 can be adjusted to a position that matches the discharge port of the ball mill drum 4, so that the ingredients can be directly mixed without filtering, thereby improving the flexibility of use.

[0033] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
