AI Technical Summary
The existing vertical steel ball mill produces grinding chips during the grinding process. After the grinding is completed, the staff needs to manually separate them, which increases the work intensity of the staff.
A vertical steel ball mill is designed, which adopts a cut-out structure. After grinding, the lower mill disc is turned over by rotating the rotating shaft. Both the steel balls and debris fall onto the screen plate. The debris falls through the screen holes on the screen plate, and the steel balls stay above the screen plate for easy separation.
This avoids the process of manual separation of steel balls and debris by staff, reduces work intensity for staff, and improves the automatic separation efficiency after grinding.

[0027] Embodiment 1, as Figure 1 As shown, a vertical steel ball mill includes a gantry 1, to which a first motor 2 is fixedly connected, to which an output shaft of the first motor 2 is fixedly connected a cylinder 3, to which an upper grinding disc 4 is fixedly connected a piston rod of the cylinder 3, and a lower grinding disc 5 is arranged on the gantry 1.
[0028] Reference Figures 1 to 3 , a material discharge structure 6 is provided on the gantry 1, and the material discharge structure 6 is mainly composed of two rotating shafts 61, and the two rotating shafts 61 are respectively rotatably connected to the two sides of the gantry 1, and one end of the rotating shaft 61 is fixedly connected to the lower grinding disc 5, and a material receiving box 62 is fixedly connected to the gantry 1, and a screen plate 63 is provided in the material receiving box 62, and the steel ball is placed in the lower grinding disc 5, and the cylinder 3 is started. The piston rod of the cylinder 3 drives the upper grinding disc 4 to descend and fit with the surface of the steel ball, and the first motor 2 is started. The output shaft of the first motor 2 drives the upper grinding disc 4 to rotate to grind the steel balls. After grinding, the two rotating shafts 61 are rotated to make the lower grinding disc 5 flip over, and the steel balls and debris in the lower grinding disc 5 fall onto the screen plate 63, and the debris falls through the sieve holes on the screen plate 63, while the steel balls remain above the screen plate 63, which is convenient for separating them, thereby avoiding the existing vertical steel ball mill during the grinding process. Grinding debris will be generated. After the grinding is completed, the staff needs to manually separate the steel balls from the debris, which increases the staff's work intensity. One end of the rotating shaft 61 is fixedly connected to a fixed block 66, and a rod 67 is slidably inserted on the fixed block 66. Slots 68 are respectively provided on both sides of the gantry 1, and the rotating shaft 61 is driven to rotate by the rod 67, which makes the operation more convenient. In the grinding process, the two rods 67 are respectively inserted into the corresponding slots 68 to limit the lower grinding disc 5, making the grinding process more stable. A door panel 64 is rotatably connected to the material receiving box 62, and a limiting block 65 is rotatably connected to the material receiving box 62. When the debris falls into the material receiving box 62, the door panel 64 is rotated outward to allow the steel balls to slide along the screen plate 63. The staff can collect the steel balls at the exit, and the limiting block 65 can limit the door panel 64 during the screening process.
[0029] Reference Figure 2 and Figure 4The sieve plate 63 is locked and the locking cam 72 is engaged with the locking cam 73. The locking cam 73 is engaged with the locking cam 73 by the spring 73. The locking cam 73 is engaged with the locking cam 73 and the locking cam 73 is engaged with the locking cam 73. The sieve plate 63 slides right and left on the spring 73, and the screening efficiency is further improved. A second motor 76 is fixedly connected to the fixed plate 75, and the output shaft of the second motor 76 is fixedly connected to the elliptical block 77. When the second motor 76 is started, the output shaft of the second motor 76 drives the elliptical block 77 to rotate, thereby further improving the convenience of operation.
[0030] The working principle is as follows: the steel ball is placed in the lower grinding disc 5, the cylinder 3 is started, and the piston rod of the cylinder 3 drives the upper grinding disc 4 to descend and fit with the surface of the steel ball, the first motor 2 is started, and the output shaft of the first motor 2 drives the upper grinding disc 4 to rotate to grind the steel ball. After grinding, the two rotating shafts 61 are rotated to make the lower grinding disc 5 flip over, and the steel balls and debris in the lower grinding disc 5 fall onto the sieve plate 63, and the debris falls through the sieve holes on the sieve plate 63, while the steel balls remain above the sieve plate 63, which is convenient for separation, thereby avoiding the situation that the current vertical steel ball mill will generate grinding debris during the grinding process, and the staff needs to manually separate the steel balls and debris after the grinding is completed, which increases the work intensity of the staff. The rotating shaft 61 is driven to rotate by the insertion rod 67, which makes the operation more convenient, and during the grinding process, the two insertion rods 67 are respectively inserted into the corresponding card slots 68, which can limit the lower grinding disc 5, making the grinding process more stable. When the debris falls into the receiving box 62 The staff can collect the steel balls at the exit by rotating the door panel 64 outwards. During the screening process, the limit block 65 can limit the door panel 64. The reciprocating sliding of the screen panel 63 during screening can improve the screening efficiency. When the staff slides the screen panel 63 to the left, the spring 73 will be squeezed to contract. When the screen panel 63 slides to the leftmost end, the screen panel 63 is released. The screen panel 63 slides to the right under the action of the rebound elastic force of the spring 73, making the reciprocating operation more convenient. Sliding the sieve plate 63 by sliding the slide rod 74 can make the sliding operation more convenient. Rotating the elliptical block 77, when the long diameter end of the elliptical block 77 contacts the rectangular plate 78, will push the sieve plate 63 to slide left. When the elliptical block 77 rotates to the short diameter end and contacts the sieve plate 63, the sieve plate 63 slides left and right on the spring 73, and so on. The screening efficiency is further improved. The second motor 76 is started, and the output shaft of the second motor 76 drives the elliptical block 77 to rotate, which further improves the convenience of operation.
