Detailed Implementation

[0022] Please see Figures 1-6The fine crushing and separation production line includes a silo 1, a feeder 2 at the bottom of the silo 1, a first conveyor 3 at the bottom of the feeder 2, a first cantilever screen 4 on the left side of the first conveyor 3, a centrifugal crusher 5 on the right side of the first conveyor 3, a second conveyor 6 at the bottom of the centrifugal crusher 5, a second cantilever screen 7 on the right side of the second conveyor 6, a third conveyor 8 at the bottom of the second cantilever screen 7, a first circular motion screen 9 on the right side of the third conveyor 8, a fourth conveyor 10 at the bottom of the first circular motion screen 9, and a third conveyor 9 on the right side of the fourth conveyor 10. The dual-circular motion screening machine 11, by setting up a first conveyor 3, a first cantilever screening machine 4, a centrifugal crushing and separating machine 5, a second conveyor 6, a second cantilever screening machine 7, a third conveyor 8, a first circular motion screening machine 9, a fourth conveyor 10, and a second circular motion screening machine 11, has a powerful material processing capacity. It can not only solve the crushing and shaping needs of various materials such as metal ores, non-metals, building materials, artificial sand, and metallurgical slag, and produce various finished products that meet industrial standards, but also efficiently crush and separate two materials that are stuck together, greatly improving the diversity and flexibility of material processing and meeting the complex requirements of different industries for material processing.

[0023] Please see Figure 1 A return conveyor 12 is installed on the left side of the second cantilever screen 7. The discharge hopper on the left side of the return conveyor 12 is located at the top of the centrifugal crusher 5. By setting up the return conveyor 12, the non-compliant materials screened by the second cantilever screen 7 are transported back to the centrifugal crusher 5 for further crushing and separation. This improves the crushing and separation accuracy of the materials, ensures that the final product meets the quality standards, and makes full use of equipment resources, avoiding material waste.

[0024] Please see Figure 1 The first cantilever screen 4, the second cantilever screen 7, the first circular motion screen 9, and the second circular motion screen 11 are each equipped with a discharge conveyor 13 on one side. There are six discharge conveyors 13 in total. The discharge conveyors 13 enable the non-conforming materials generated by each screen during the screening process to be conveniently and quickly transported out, facilitating centralized processing of non-conforming materials and improving the overall operating efficiency of the production line and the convenience of material management.

[0025] Please see Figure 5The first cantilever screening machine 4 includes a casing 40. A first screen plate 41 and a second screen plate 42 are respectively installed in the inner cavity of the casing 40. A first support base 43 is fixedly connected to the surface of the casing 40. A spring 44 is fixedly connected to the bottom of the first support base 43. A second support base 45 is fixedly connected to the bottom of the spring 44. A funnel 46 is fixedly connected to the bottom of the second support base 45. The bottom of the funnel 46 is fixedly connected to the first conveyor 3 through a bracket. By setting the first screen plate 41 and the second screen plate 42, the material entering the first cantilever screening machine 4 can be screened in multiple stages, improving the screening accuracy and effectively separating materials of different particle sizes to meet the processing needs of materials of different particle sizes. The design of the funnel 46 facilitates the collection of the screened material, realizes the smooth conveying of the material, and ensures the continuous operation of the production line.

[0026] Please see Figure 5 A motor 47 is fixedly connected to the surface of the funnel 46 via a support plate. A pulley is fixedly connected to the shaft of the motor 47. The pulley is connected to a drive wheel 48 via a belt drive. One side of the drive wheel 48 is movably connected to the housing 40 via a rotating rod. An eccentric block 49 is fixedly connected to the surface of the drive wheel 48 via the rotating rod. The motor 47 drives the eccentric block 49 to rotate via the pulley, belt, and drive wheel 48. The centrifugal force generated by the eccentric block 49 causes the housing 40 to vibrate, providing power for the screening operation of the first cantilever screener 4. This ensures that the screening process can be carried out efficiently and stably. The setting of the eccentric block 49 makes the vibration of the housing 40 more uniform and regular, which is conducive to improving the screening efficiency and quality of materials, and enabling materials of different particle sizes to be separated more accurately and quickly.

[0027] Please see Figure 5 The first cantilever screening machine 4 is provided with a guide hopper 410 on the left side. The left sides of the first screen plate 41 and the second screen plate 42 both extend into the inner cavity of the guide hopper 410. The guide hopper 410 can accurately guide the material screened by the first screen plate 41 and the second screen plate 42 to the designated position, which is convenient for the separate collection and processing of materials of different particle sizes, avoids the chaos and spillage of materials during the discharge process, and improves the efficiency and accuracy of material collection.

[0028] Please see Figure 5A pad 413 is fixedly connected to the inner wall of the housing 40. The bottoms of the first screen plate 41 and the second screen plate 42 are in contact with the pad 413. Bolts 411 are connected through the surface of the housing 40. The surfaces of the first screen plate 41 and the second screen plate 42 are provided with locking holes 412. The bolts 411 pass through the housing 40 and the locking holes 412 respectively. The pad 413 provides stable support for the first screen plate 41 and the second screen plate 42. The cooperation of the bolts 411 and the locking holes 412 enables the screen plates to be firmly fixed in the housing 40, preventing the screen plates from shifting or loosening due to vibration during the screening process, ensuring the normal operation and screening accuracy of the screening work, and facilitating the disassembly and cleaning of the screen plates.

[0029] In operation, the feeder 2 at the bottom of the hopper 1 evenly conveys the material to the first cantilever screen 4. Then, the motor 47 is started, and its shaft drives the pulley to rotate. The pulley, in turn, drives the drive wheel 48 via a belt. The drive wheel 48 drives the eccentric block 49 to rotate. The centrifugal force generated by the eccentric block 49 causes the casing 40 to vibrate evenly and regularly, causing the material to jump and tumble on the first screen plate 41 and the second screen plate 42, thus screening the material. Material that does not pass through the screen plates is conveyed to the discharge conveyor 13 via the guide hopper 410. Material that passes through the screen plates flows through the funnel 46 to the first conveyor 3, and then to the centrifugal crusher 5. The centrifugal crusher 5 utilizes the centrifugal force generated by high-speed rotation to powerfully crush and separate the material, achieving efficient crushing and separation. The crushed material is then discharged from the centrifugal crusher. The bottom of the separator 5 falls onto the second conveyor 6, which then transports the material to the second cantilever screen 7 on the right for secondary screening. The working principle of the second cantilever screen 7 is the same as that of the first cantilever screen 4. The material that does not meet the requirements after being screened by the second cantilever screen 7 is transported back to the top bucket of the centrifugal crusher 5 via the return conveyor 12 and re-enters the centrifugal crusher 5 for further crushing and separation. After passing through the second cantilever screen 7, the material that meets the requirements is transported to the first circular motion screen 9 on the right via the third conveyor 8. The first circular motion screen 9 uses the circular motion screening principle to perform finer screening of the material and further separate qualified materials of different particle sizes. The qualified material is transported to the second circular motion screen 11 on the right via the fourth conveyor 10 for further fine screening, and finally the finished product is obtained.

[0030] In summary, this fine crushing and separation production line, by setting up a first conveyor 3, a first cantilever screen 4, a centrifugal crusher and separator 5, a second conveyor 6, a second cantilever screen 7, a third conveyor 8, a first circular motion screen 9, a fourth conveyor 10, and a second circular motion screen 11, solves the problem that traditional processing methods cannot effectively remove residual asphalt from stones, making it difficult to meet the requirements for qualified stones for highway maintenance.
