- the granulating apparatus 100 with the same throughput and the granulating apparatus according to the comparative example are compared.
- the area of the side surface 10C of the die 10 of the granulator 100 is equal to the area of the processed surface 210A of the granulator according to the comparative example.
- the area of the contact surface 21A of each cutter blade 21 is equal to the area of the contact surface 241A of each cutter blade 221 in the granulator according to the comparative example.
- the projected area of the side surface 10C when projected onto a plane perpendicular to the central axis C is smaller than the area of the side surface 10C, and therefore smaller than the area of the processed surface 210A in the comparative example.
- the granulator 100 can be made smaller than the granulator according to the comparative example. Furthermore, as a result, the maintainability and operability of the granulator 100 are improved as compared with the granulator according to the comparative example.
- the die 10 can be made lighter than the die 210 of the comparative example.
- the ratio of the weight of the die 10 divided by the area of the side surface 10C can be smaller than the ratio of the weight of the comparative die 210 divided by the area of the working surface 210A.
- the die 10 receives part of the weight of the cutter blades 21 moving above the side surface 10C of the die 10, the weight to be received by the cutter blade holder 22 is less than the total weight of the plurality of cutter blades. Therefore, the cutter blade holder 22 can be made smaller and/or lighter than the cutter blade holder 222 of the comparative example.
- the cutter blade holder 222 since the cutter blade holder 222 receives the total weight of the plurality of cutter blades 221, the difference between the weight of the cutter blade unit 220 on the cutter blade 221 side and the weight on the shaft 241 side can be compared. As a result, the cutter blade 221 side moves relatively downward and the shaft 241 side moves relatively upward, and the cutter blade unit 220 may tilt with respect to the direction perpendicular to the processing surface 210A of the die 210 . That is, there is a possibility that the rotation axis O of the cutter blade unit 220 is tilted with respect to the center axis C of the die 210 . In this case, it becomes difficult for each cutter blade 221 to evenly contact the working surface of the die.
- the weight to be received by the cutter blade holder 22 is less than the total weight of the plurality of cutter blades, so the rotation axis O of the cutter blade unit 20 is less inclined with respect to the central axis C. .
- each cutter blade 21 can evenly contact the side surface 10C of the die 10 .
- the radius of the outermost periphery of each cutter blade 21 is shorter than the radius of the outermost periphery of each cutter blade 221 of the comparative example. Therefore, when the number of rotations is equal under the above comparison, the peripheral speed of each cutter blade 21 is lower than the peripheral speed of each cutter blade 221 in the comparative example. On the other hand, when the peripheral speed is equal under the above comparison, the number of rotations of each cutter blade 21 increases more than the number of rotations of each cutter blade 221 of the comparative example.
- the peripheral speed of the cutter blade is limited from the viewpoint of preventing cavitation in the coolant.
- the number of revolutions of the cutter blade 21 can be increased more than the comparative example, so that one cutter blade 21 can be used more.
- the throughput of pellets can be increased without increasing the number of cutter blades 21 as compared with the comparative example. From a different point of view, in the granulator 100, the number of cutter blades 21 can be reduced without lowering the pellet manufacturing efficiency, compared to the comparative example.
- the configuration of the granulator 100 other than the die 10, the cutter blade unit 20, and the resin cutting device 30 may be the same as the configuration of the granulator according to the comparative example other than the die 210 and the cutter blade unit 220. good.
- the hopper 1, the screw mixer 2, the diverter valve 3, the gear pump 4, and the screen changer 5 may have configurations equivalent to those of the granulator according to the comparative example.
- the method for producing pellets according to the present embodiment uses the granulator 100, which is smaller than the granulator according to the comparative example and has improved maintainability and operability, so the granulator according to the comparative example is used. A large amount of pellets can be produced with high efficiency compared to the pellet production method used.
