When the roll crusher works, the gravel is crushed by the relative rotation of two roller wheels to obtain the required grit.

[0003] Chinese Patent No. 202320273069.6 discloses a new type of oil shaft seat roll crusher, which relates to the technical field of roll crushers, including a fixed roll and a movable roll. Both ends of the fixed roll are rotationally connected to the mounting frame through fixed bearing seats, and both ends of the movable roll are rotationally connected to the mounting frame through movable bearing seats. The movable bearing seat and the mounting frame are slidably connected through a mutually matched oil storage box and a limiting block. The fixed roll and the movable roll are both driven to rotate by a driving mechanism. When the roll crusher in this patent is in use, the fixed roll and the movable roll are both driven to rotate by the driving mechanism. Since both rollers have power, internal cracks are likely to appear in the processed stone materials, resulting in a large amount of stone powder in the obtained grit.

Detailed implementation manners

[0023] In order to enable those skilled in the art to better understand the technical solutions of the present utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0024] As Figure 1-7 shown, a differential surface double roll machine provided by an embodiment of the present utility model includes a driving roll 1 and a driven roll 2. Both ends of the driving roll 1 are connected to a first bearing block 3 through bearings. A first speed measurement sensor 9 is fixed on the outer wall of one side of the first bearing block 3. The input end of the first speed measurement sensor 9 is connected to one end of the driving roll 1 by a key. Both ends of the driven roll 2 are connected to a second bearing block 4 through bearings. A second speed measurement sensor 10 is fixed on the outer wall of one side of the second bearing block 4. The input end of the second speed measurement sensor 10 is connected to one end of the driven roll 2 by a key.

[0025] Specifically, in this embodiment, it includes a driving roller 1 and a driven roller 2. Both ends of the driving roller 1 are connected with a first bearing block 3 through bearings. A first speed sensor 9 is fixed on the outer wall of one side of the first bearing block 3. The input end of the first speed sensor 9 is connected with one end of the driving roller 1 by a key. The first speed sensor 9 is used to detect the rotation speed of the driving roller 1. Both ends of the driven roller 2 are connected with a second bearing block 4 through bearings. A second speed sensor 10 is fixed on the outer wall of one side of the second bearing block 4. The input end of the second speed sensor 10 is connected with one end of the driven roller 2 by a key. The second speed sensor 10 is used to detect the rotation speed of the driven roller 2. The roller press also has a frame 20. During use, both the first bearing block 3 and the second bearing block 4 are fixed to the frame 20, and a certain gap is provided between the driving roller 1 and the driven roller 2. During operation, the driving roller 1 rotates, and the driven roller 2 rotates through the frictional force of the material. Thus, a speed difference is formed between the two rollers and the material forms a material layer. After the material forms a material layer, it is in a state of 360° tumbling extrusion and grinding. 80% of the stone material achieves the effect of stone hitting stone, greatly increasing the service life of the driving roller 1 and the driven roller 2.

[0026] A differential curved surface roller press provided by the present utility model, through the provided driving roller 1 and driven roller 2, when the driving roller 1 rotates, drives the driven roller 2 to rotate through the frictional force of the stone material, enabling the stone material to achieve the effect of laminated crushing, with good particle shape, no internal cracks in the stone material, reducing the amount of stone powder, thereby improving the quality of stone material processing. And through the first speed sensor 9 and the second speed sensor 10, the rotation speeds of the driving roller 1 and the driven roller 2 can be detected respectively, making it convenient to monitor the working state of the roller press.

[0027] In another embodiment provided by the present utility model, an installation ring 11 is fixed outside the speed measurement sensor 9. A connecting column 12 is fixed on the outer wall of one side of the bearing seat 1. A connecting ring 13 is sleeved outside the connecting column 12. A pressing plate 17 is integrally formed on the outer wall of one side of the connecting ring 13. The top end of the connecting column 12 is hinged with a cam 15 through a shaft. When the cam 15 rotates, it presses the connecting ring 13. A force - adding plate 16 is integrally formed on the outer wall of one side of the cam 15, which is used to facilitate the rotation of the cam 15. A gasket 14 is sleeved outside the connecting column 12, and the gasket 14 is located between the cam 15 and the connecting ring 13. The gasket 14 has a certain elasticity, making the pressing of the cam 15 on the gasket 14 more stable. Since the working environment of the roller press has a high humidity, if the speed measurement sensor 9 is fixed to the bearing seat 1 with bolts, the bolts will be rusted in the threads, making the disassembly of the speed measurement sensor 9 inconvenient. Through the rotation of the cam 15, the pressing plate 17 can press the installation ring 11, so that the speed measurement sensor 9 will not have the phenomenon of thread rust when fixed, and thus the installation and disassembly of the speed measurement sensor 9 are more convenient. A convex block 19 is integrally formed on the outer wall of the pressing plate 17 close to the installation ring 11, and a groove 18 adapted to the convex block 19 is formed on the outer wall of the installation ring 11. By the cooperation of the convex block 19 and the groove 18, the pressing of the pressing plate 17 on the installation ring 11 is more firm.

[0028] In another embodiment provided by the present utility model, a speed reducer 5 is arranged on one side of the driving roller 1. The speed reducer 5 is fixed to the frame 20. One end of the output shaft of the speed reducer 5 is connected with a coupling 6, and one end of the driving roller 1 is connected with the coupling 6. During use, the input shaft of the speed reducer 5 is driven to rotate by a motor, so that the speed reducer 5 increases the torque of the motor and then drives the driving roller 1 to rotate. The use of the coupling 6 prevents the vibration generated when the driving roller 1 works from being transmitted to the speed reducer 5, thereby extending the service life of the speed reducer 5. Arc convex rings 7 are integrally formed on the outer walls of both the driving roller 1 and the driven roller 2 at equal intervals. An arc groove 8 is arranged between two adjacent arc convex rings 7. Through the arranged arc convex rings 7 and arc grooves 8, a mutually - matching curved surface is formed on the surfaces of the driving roller 1 and the driven roller 2, which is convenient for guiding hard stone materials into the arc groove 8 for centralized extrusion, achieving a more smooth effect when the stone materials are roll - pressed, and enabling the materials to be ground in a 360° state in the curved surface of the rollers. The contact area between the materials and the roller surface increases by 30%, so the grain shape of the produced sand grains is good and the output is high.

[0029] Working principle: During use, the input shaft of the speed reducer 5 is rotated by the motor, causing the speed reducer 5 to drive the driving roller 1 to rotate. Then, the stone material is placed between the driving roller 1 and the driven roller 2. When the driving roller 1 rotates, it drives the stone material to move. The stone material drives the driven roller 2 to rotate through friction, so that the stone material is crushed between the driving roller 1 and the driven roller 2. Since the driven roller 2 only rotates through friction, the stone material achieves the effect of laminating crushing, with good particle shape, no internal cracks in the stone material, and reduced amount of stone powder. There is a rotational speed difference between the driving roller 1 and the driven roller 2. The rotational speeds of the driving roller 1 and the driven roller 2 can be detected respectively by the speed sensor one 9 and the speed sensor two 10, making it convenient to monitor the working state of the double-roll crusher. When it is necessary to replace the speed sensor one 9, the cam 15 is rotated by the force-applying plate 16, making the pressure plate 17 and the mounting ring 11 become loose. Then, the connecting ring 13 is rotated so that the pressure plate 17 does not contact the mounting ring 11. At this time, the speed sensor one 9 can be separated from the bearing seat one 3.

[0030] Only some exemplary embodiments of the present invention have been described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present invention, the described embodiments can be modified in various different ways. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present invention.
