At this time, the material entering the rolling chamber 22 is crushed and pushed by the high-speed rotation of the eccentric rolling rotor 4. At this time, large particles are broken, and particles smaller than the aperture of the screen 3 are screened out.

[0038] A discharge port 23 is provided on the mill housing 2 near the bottom thereof, and the discharge port 23 is communicated with the discharge chamber 21 .

[0039] With this design, the qualified granular materials in the discharge chamber 21 are discharged through the discharge port 23, which is convenient for use.

[0040] A feed channel 24 is disposed above the mill housing 2 , and one end of the feed channel 24 passes through the mill housing 2 and is communicated with the milling chamber 22 .

[0041] The feed channel 24 is provided with a feed port 25 at one end thereof away from the crushing chamber 22 , and the material to be crushed is fed through the feed port 25 .

[0042] With such a design, when in use, materials can be fed through the feed port 25 , and the materials enter the feed channel 24 through the feed port 25 , and are guided into the rolling chamber 22 by the flow of the feed channel 24 .

[0043] At this time, the eccentric rolling rotor 4 rotates in the rolling chamber 22 to roll and crush the materials in the rolling chamber 22, and qualified granular materials can be screened out in real time through the screen 3, which is convenient for use.

[0044] The eccentric rolling rotor 4 includes a rotor sleeve 41 , which is coaxially installed in the rolling chamber 22 , and at least two rolling blocks 42 are installed outside the rotor sleeve 41 , and the two corresponding rolling blocks 42 are symmetrically arranged.

[0045] A rolling surface 44 is provided on a side of the rolling block 42 close to the screen 3 , and the rolling surface 44 is spaced apart from the inner wall of the screen 3 .

[0046] The rolling block 42 and the rotor sleeve 41 are fixedly connected; the rotation of the rotor sleeve 41 can drive the rolling block 42 to rotate, which is convenient for use.

[0047] The cross-sectional shape of the rolling surface 44 is an arc-shaped surface, and the rolling surface 44 and the screen 3 are eccentrically arranged.

[0048] Depend on Figure 4 As shown, the spacing distance between the rolling surface 44 and the screen 3 gradually increases or decreases from one side of the rolling surface 44 to the other side.

[0049] The lower end of the rotor sleeve 41 is spaced apart from the inner surface of the lower end of the screen 3 , and a positioning connecting plate 43 is fixedly connected to the lower end of the rotor sleeve 41 .

[0050] The outer surface of the positioning connecting plate 43 and the inner surface of the screen 3 are arranged at intervals.

[0051] One end of the rolling block 42 close to the positioning connecting plate 43 is fixedly mounted on the positioning connecting plate 43 to facilitate assembly and installation.

[0052] In this embodiment, the positioning connection plate 43 and the rotor sleeve 41 are fixedly connected by welding.

[0053] In this embodiment, the rolling block 42 and the positioning connection plate 43 are fixedly connected by welding, which is convenient for assembly and installation and can reduce production costs.

[0054] With such a design, the rotation of the rotor sleeve 41 can drive the rolling block 42 to rotate, and the rolling block 42 is used to roll the material through the cooperation of the rolling surface 44 and the inner surface of the screen 3, which is convenient to use.

[0055] When in use, taking sugar cubes as an example, the sugar cubes to be crushed are transported to the rolling chamber 22 through the feed port 25 and the feed channel 24. At this time, the driving assembly 5 outputs power to drive the eccentric rolling rotor 4 to rotate at high speed as a whole.

[0056] At this time, the rotor sleeve 41 drives the rolling block 42 to rotate at high speed in the rolling chamber 22, and the material entering the rolling chamber 22 is crushed and crushed under the high-speed rotation of the rolling block 42. At this time, large particles are broken, and particles smaller than the aperture of the screen 3 are screened out.

[0057] At this time, the qualified granular materials screened out by the screen 3 enter the discharge chamber 21, and the qualified granular materials in the discharge chamber 21 are discharged from the discharge port 23, which is convenient for use.

[0058] The driving assembly 5 includes a driving motor 51 mounted on a mounting bracket 1. A transmission box 52 is mounted on the mounting bracket 1 above the mill housing 2. The power output end of the driving motor 51 is connected to the power input end of the transmission box 52 through a transmission assembly.

[0059] With this design, the drive motor 51 outputs power to drive the transmission component to work, and at this time the transmission component performs transmission to drive the transmission box 52 to work.

[0060] The transmission assembly includes a first pulley 54 , which is mounted on the driving motor 51 . A second pulley 55 is fixedly mounted on the power input end of the transmission box 52 .

[0061] A transmission belt 56 is sleeved between the first pulley 54 and the second pulley 55 , and the first pulley 54 and the second pulley 55 are connected in transmission via the transmission belt 56 .

[0062] Designed in this way, the driving motor 51 is used to drive the first pulley 54 to rotate. The first pulley 54 rotates to drive the second pulley 55 to rotate through the transmission belt 56. The second pulley 55 rotates to drive the transmission box 52 to work.

[0063] In addition to this embodiment, the transmission assembly may also adopt transmission modes such as sprocket chain transmission, gear transmission, etc.

[0064] A transmission shaft 53 is transmission-connected to the power output end of the transmission box 52 , and the transmission shaft 53 and the rotor sleeve 41 are coaxially arranged.

[0065] The lower end of the transmission shaft 53 passes through the upper end surface of the mounting bracket 1 and extends to the central hole of the rotor sleeve 41 . The transmission shaft 53 is transmission-connected to the rotor sleeve 41 .

[0066] With such a design, the transmission box 52 is used to drive the transmission shaft 53 to rotate. At this time, the rotation of the transmission shaft 53 can drive the rotor sleeve 41 to rotate, thereby driving the eccentric rolling rotor 4 to rotate in the rolling chamber 22, which is convenient to use.

[0067] In this embodiment, when the driving motor 51 drives the eccentric rolling rotor 4 to rotate through the transmission assembly and the transmission box 52, the rotation speed of the eccentric rolling rotor 4 is 960 rpm.

[0068] With this design, the drive motor 51 outputs power through the transmission assembly and the transmission box 52 to drive the eccentric rolling rotor 4 to rotate at high speed, which is convenient to use.

[0069] In this embodiment, the transmission shaft 53 and the rotor sleeve 41 are positioned by nuts to achieve transmission connection.

[0070] The lower end of the transmission shaft 53 extends to the lower end surface of the rotor sleeve 41 and is threadedly connected with a fixing nut. The fixing nut is top-connected with the rotor sleeve 41 through an anti-rotation gasket, thereby realizing a transmission connection between the transmission shaft 53 and the rotor sleeve 41, which is convenient for assembly and installation, and easy for inspection and maintenance.

[0071] In this embodiment, the centrifugal mill for crushing sugar blocks is made of 304 stainless steel as a whole and has a fully enclosed structure. When the sugar material is crushed in the crushing chamber 22, no dust will fly out, which is convenient to use. The overall structure is simple and compact, occupies a small space, is easy to install, use and maintain, and improves the use effect.

[0072] Grease nipples are installed on the transmission box 52 at positions close to each bearing assembly, and lubricating oil is added to the bearing assembly through the grease nipples.

[0073] In this embodiment, the bearings are inspected every 360 hours and lubricating oil is added to each bearing assembly through a grease nipple.

[0074] When in use, firstly, according to the water content of the sugar material to be crushed, it is determined whether the driving assembly 5 drives the eccentric rolling rotor 4 to perform forward rotation operation or reverse rotation operation.

[0075] When crushing anhydrous sugar, forward rotation operation can be adopted, and at this time, the driving component 5 outputs power to drive the eccentric rolling rotor 4 to rotate forward.

[0076] When crushing sugar materials with a large water content, a reverse operation can be adopted, and at this time, the driving component 5 outputs power to drive the eccentric rolling rotor 4 to reverse.

[0077] The specific operation is: the sugar blocks to be crushed are added into the rolling chamber 22 through the feed port 25 and the feed channel 24. At this time, the driving motor 51 drives the transmission shaft 53 to rotate through the transmission assembly and the transmission box 52. The rotation of the transmission shaft 53 drives the eccentric rolling rotor 4 to rotate at high speed.

[0078] At this time, the rotor sleeve 41 drives the rolling block 42 to rotate at high speed in the rolling chamber 22, and the material entering the rolling chamber 22 is crushed and crushed under the high-speed rotation of the rolling block 42. At this time, large particles are broken, and particles smaller than the aperture of the screen 3 are screened out.

[0079] At this time, the qualified granular materials screened out by the screen 3 enter the discharge chamber 21, and the qualified granular materials in the discharge chamber 21 are discharged from the discharge port 23, which is convenient for use.

[0080] And at the end of normal production, the material in the centrifugal mill for crushing sugar blocks needs to be discharged to prevent sticking to the material, and then the power is turned off. In case of special circumstances and abnormal noise, the machine should be stopped immediately for inspection.

[0081] For those skilled in the art, according to the teachings of the present invention, without departing from the principles and spirit of the present invention, changes, modifications, substitutions and variations made to the implementation methods are still within the protection scope of the present invention.
