Description

Technical Field

[0001] This utility model relates to the field of materials processing technology, specifically to a ball mill device for the production of sintered corundum. Background Technology

[0002] Traditional ball milling equipment used in the production of sintered corundum suffers from numerous technical challenges in practical applications. In the feeding stage, traditional ball mills often employ gravity-feed structures, where the sintered corundum raw material falls into the mill cylinder under its own weight. This process easily leads to accumulation at the junction of the feed pipe and the mill cylinder, causing blockages. In the grinding stage, the mill cylinder of traditional equipment typically uses a single-cavity design with a single type of liner, which is insufficient for the initial crushing of raw materials, resulting in low coarse grinding efficiency. These deficiencies in feeding stability and grinding precision of existing ball milling equipment for sintered corundum production have become key factors restricting the improvement of production efficiency and product quality. Therefore, a new type of ball milling equipment capable of solving these problems is urgently needed. Utility Model Content

[0024] Working principle:

[0025] A ball milling device for producing sintered corundum includes a power motor 1, an auxiliary device 2, and a corundum ball milling device 3. In use, sintered corundum raw material enters the corundum ball milling device 3 from the auxiliary device 2. The power motor 1 drives the corundum ball milling device 3 to rotate. The sintered corundum raw material is turned into finished corundum powder in the corundum ball milling device 3, and the corundum powder is discharged from the auxiliary device 2.

[0026] Before use, place the support platform 21 in the designated position, connect the feed pipe 24 to the external feed channel, connect the discharge port on the support frame 22 to the external discharge channel, unscrew the fixing screws on the slide plate 26, and slide the slide plate 26 out along the groove on the ball mill cylinder 34 by hand to open the opening on the ball mill cylinder 34. Place the high chromium cast iron grinding balls into the coarse grinding chamber through the opening on the ball mill cylinder 34, place the silicon nitride ceramic grinding balls into the fine grinding chamber through the opening on the ball mill cylinder 34, and place the polyurethane elastomer grinding balls into the fine grinding chamber through the opening on the ball mill cylinder 34. After all the balls are placed in, slide the slide plate 26 in along the groove on the ball mill cylinder 34 to close the opening on the ball mill cylinder 34, and fix the slide plate 26 to the ball mill cylinder 34 with screws.

[0027] In operation, the power motor 1 is started. The rotation of the output shaft of the power motor 1 drives the drive gear 31 to rotate, which in turn drives the driven gear 32 to rotate. The rotation of the driven gear 32 drives the flange 33 to rotate, which in turn drives the ball mill cylinder 34 to rotate around the inner wall of the bearing 23. The rotation of the ball mill cylinder 34 drives the spiral feed block 35 to rotate. The sintered corundum raw material enters the feed pipe 24 from the external feed channel. The rotating spiral feed block 35 transports the sintered corundum raw material in the feed pipe 24 to the coarse grinding chamber in the ball mill cylinder 34. The high-chromium cast iron grinding balls and the sintered corundum raw material in the coarse grinding chamber rotate with the ball mill cylinder 34. The high-chromium cast iron grinding balls perform preliminary crushing of the sintered corundum raw material in the coarse grinding chamber. The composite liner 36 is adapted for the initial crushing of sintered corundum raw materials. The initially crushed corundum enters the fine grinding chamber through the coarse grinding filter plate 39. The silicon nitride ceramic grinding balls in the fine grinding chamber and the initially crushed corundum rotate with the ball mill cylinder 34. The silicon nitride ceramic grinding balls turn the initially crushed corundum into corundum powder in the fine grinding chamber. The silicon nitride ceramic liner 37 in the fine grinding chamber reduces the introduction of metal impurities during the grinding process. The corundum powder enters the fine grinding chamber through the fine grinding filter plate 310. The polyurethane elastomer grinding balls in the fine grinding chamber and the corundum powder rotate with the ball mill cylinder 34. The polyurethane elastomer grinding balls turn the corundum powder into finished corundum powder in the fine grinding chamber. After being subjected to stress, the polyurethane elastic liner 38 in the fine grinding chamber reduces the direct impact of stress on the liner and protects the surface integrity of the liner.

[0028] After use, remove the sealing plate 25 from the groove on the support frame 22 to open the discharge port on the support frame 22. Start the blower motor 27 fixed on the fixed frame 210. The output shaft of the blower motor 27 rotates, which drives the rotating shaft 28 to rotate. The rotation of the rotating shaft 28 drives the spiral blade 29 to rotate. The rotation of the spiral blade 29 blows the finished corundum powder from the ball mill cylinder 34 through the discharge port into the external discharge channel.
