[0026] By adopting the above technical solution, the roller mill can collect the crushed products when needed through the cooperation of structures such as the fan 535 and the collection box 533, thereby facilitating the collection work of the staff and reducing the difficulty of the work.

[0027] Specifically, the collecting assembly 53 further includes a rotating plate 531 and a screw 532 . The screw 532 is threadedly mounted on a side of the collecting box 533 away from the multiple fans 535 , and the rotating plate 531 is mounted on a side of the screw 532 away from the collecting box 533 .

[0028] By adopting the above technical solution, the staff can connect or separate the collection box 533 and the bottom frame 51 through the screw 532 when necessary, thereby facilitating the staff to load and unload the collection box 533.

[0029] When the present embodiment is used, when it is necessary to use a high-pressure roller mill to process alumina, the staff puts the collection box 533 in the collection assembly 53 in the mobile collection device 5 into the bottom frame 51 under the two hydraulic cylinders 7, and the staff rotates the rotating plate 531 so that the screw 532 is threadedly connected with the collection box 533.

Under the action of each fan 535, the crushed alumina is sucked into the collection box 533, and then the filter cloth 534 blocks the alumina. When all the alumina is crushed and enters the collection box 533, the fans 535 are turned off and the work is completed.

[0030] Example 2

[0031] The difference between this embodiment and embodiment 1 is that the vibration connection device 8 includes a support plate 81, a connection block 83 and a vibrator 84, the connection blocks 83 are installed on both sides of the shell 1, the support plate 81 is installed on the side of the hydraulic cylinder 7 close to the connection block 83, and the vibrator 84 is installed above the connection block 83.

[0032] By adopting the above technical solution, the roller mill can drive the shell 1 and other structures to vibrate to a certain extent through the cooperation of the vibrator 84 and the connecting block 83 when needed, thereby preventing part of the crushed product from staying somewhere in the shell 1, and better meeting the work needs.

[0033] Specifically, the vibration connection device 8 also includes an elastic rubber frame 82 and a damper 85 . The elastic rubber frame 82 is installed between the connection block 83 and the support plate 81 . The damper 85 is installed between the connection block 83 and the support plate 81 and at a position inside the elastic rubber frame 82 .

[0034] By adopting the above technical solution, the roller mill can buffer the vibration generated by the vibrator 84 to a certain extent through the cooperation of the elastic rubber frame 82 and the damper 85, thereby reducing the possibility that the vibration generated by the vibrator 84 will cause adverse effects on the surroundings.

[0035] When this embodiment is used, during processing, the staff can start the vibrators 84 in the two vibration connecting devices 8, and the two vibrators 84 drive the shell 1 and other structures to vibrate through the two connecting blocks 83, thereby preventing part of the crushed aluminum oxide from staying somewhere in the shell 1. The elastic rubber frame 82 and the damper 85 between the support plate 81 and the connecting block 83 can buffer the vibration generated by the vibrator 84 to a certain extent, thereby reducing the possibility that the vibration generated by the vibrator 84 will cause adverse effects on the surroundings.

[0036] The structure and principle of the shell 1, the tile roller assembly 2 composed of a rotating roller, a tile roller and bolts, the feed port 3, the shaft 4, the cylinder 6, and the hydraulic cylinder 7 in the utility model have been disclosed in the high-pressure roller mill disclosed in Chinese patent application No. 201620913665.6. Its working principle is that the motor is fixed to the outer wall of the shell, and the motor is connected to one end of the shaft. During operation, the motor drives the rotating roller to rotate, and the stone enters the shell from the feed port. The hydraulic cylinder pushes the shell downward to apply pressure. Under the rolling of the rotating roller and the shell, the stone is crushed in the shell. For stones that are not easy to crush, they stay in the shell and are continuously rolled until they are crushed. Finally, the crushed stone is discharged through the cylinder, which is more The replacement cylinder can be applied to crush stones of different volumes, with a simple structure and easy operation. The tile roller is bolted to the rotating roller, so it is easy to replace the tile roller after it is damaged, avoiding damage caused by direct rolling of the rotating roller and high replacement cost. It is made of iron-based alloy with excellent impact toughness, good stress fatigue resistance and hot and cold fatigue resistance, low price and cost saving. The cylinder and the shell are connected by threads, and the cylinder can be replaced according to the needs of crushing materials of different volumes. At the same time, the upper opening of the cylinder frustum is smaller than the lower opening to better leak the crushed material and reduce the risk of the cylinder opening being blocked. Setting multiple cylinders is more conducive to the discharge of crushed stones and improves work efficiency.

[0037] The structure and principle of the vibrator 84 in the utility model have been disclosed in an easy-to-clean concrete mixing device disclosed in Chinese patent application No. 201821054815.8. Its working principle is composed of components such as springs, mass blocks, and motors. When the spring or mass block is subjected to external force from the motor, elastic deformation or displacement will occur, thereby generating vibration.

[0038] The structure and principle of the damper 85 in the utility model have been disclosed in a smart home washing machine shock absorbing device disclosed in Chinese patent application No. 201721446985.6. Its working principle consists of a piston and an oil tank, which is filled with oil. When the object moves, the piston moves in the oil, thereby consuming energy and slowing down the movement of the object.

[0039] The working principle and use process of the utility model are as follows: when it is necessary to use a high-pressure roller mill to process alumina, the staff puts the collection box 533 in the collection assembly 53 in the mobile collection device 5 into the bottom frame 51 under the two hydraulic cylinders 7, and the staff rotates the rotating plate 531 so that the screw 532 is threadedly connected with the collection box 533. Then the staff pushes the roller mill and moves the roller mill to the working position through each brake wheel 52. Then the alumina to be processed is sent into the shell 1 through the feed port 3. A motor is arranged outside the shell 1, and the motor is connected to the shaft 4. The motor drives the shaft 4 to rotate, thereby driving the tile roller assembly 2 to roller-grind the alumina. The crushed alumina passes through each cylinder 6 and leaves the shell 1, and each fan 53 is started. 5. Under the action of each fan 535, the crushed aluminum oxide is sucked into the collection box 533, and then the filter cloth 534 blocks the aluminum oxide. When all the aluminum oxide is crushed and enters the collection box 533, the fans 535 are turned off and the work is completed. During processing, the staff can start the vibrators 84 in the two vibration connection devices 8. The two vibrators 84 drive the shell 1 and other structures to vibrate through the two connection blocks 83, thereby preventing part of the crushed aluminum oxide from staying somewhere in the shell 1. The elastic rubber frame 82 and the damper 85 between the support plate 81 and the connection block 83 can buffer the vibration generated by the vibrator 84 to a certain extent, thereby reducing the possibility that the vibration generated by the vibrator 84 will cause adverse effects on the surroundings.
