Optionally, the crushing chamber 1 may be in a vertical state or a horizontal state, or may have a certain inclination angle, as long as the power mechanism can transport the material in the crushing chamber 1 along the direction of the feeding portion 2, the first air injection mechanism 4, the liner 6, the grading mechanism 5 and the discharging portion 3, and at the same time, it is ensured that the first air injection mechanism 4, the liner 6 and the grading mechanism 5 can perform the above-mentioned function on the material correspondingly.

In this embodiment, the inner container 6 is disposed in the crushing chamber 1, and the first channel structure 7 through which the material can pass is disposed inside the inner container 6, so that after the material introduced by the feeding portion 2 is crushed by the first air injection mechanism 4, the material moves toward the discharging portion 3 through the first channel structure 7 of the inner container 6, and collides with the first channel structure 7 when passing through the first channel structure 7, thereby buffering the impact force of the material on the classifying mechanism 5, and prolonging the service life of the classifying mechanism 5.

In this embodiment, a plurality of second air injection mechanisms 8 are arranged in the crushing chamber 1, the second air injection mechanisms 8 are located between the first air injection mechanisms 4 and the grading mechanisms 5, and the second air injection mechanisms 8 are used for outputting air jet flow and acting on the second materials blocked by the grading mechanisms 5, that is, the materials which do not reach the specified granularity, so that the materials which do not reach the specified granularity are crushed for the second time in the crushing chamber 1.

Further, because the jet mill need be constantly added raw materials by feed portion 2 when handling the material, and because the material that does not reach appointed granularity in the material of handling earlier can be blockked by hierarchical mechanism 5 and fall to first air injection mechanism 4 department and handle once more, be equivalent to first air injection mechanism 4 need handle newly-added raw materials and the remaining material that does not reach appointed granularity when handling earlier simultaneously, then can lead to the easily emergence kibbling phenomenon of material of small granule, particle distribution range is wide, and then reduced crushing efficiency, still lead to holistic jet mill can consume great. Consequently set up a plurality of second air jet mechanism 8 between first air jet mechanism 4 and grading mechanism 5, can block the material that does not reach appointed granularity of whereabouts to block by grading mechanism 5 through a plurality of second air jet mechanism 8 and carry out the regrinding, can directly deliver regrinding's material to grading mechanism 5 through power unit after the regrinding, the remaining material that does not reach appointed granularity when making newly-added raw materials and prior processing separately handles in the broad sense, and then avoid by a wide margin that the material easily appears the kibbling phenomenon, and simultaneously, the crushing efficiency is improved, the energy consumption of holistic fluid energy mill has been reduced.

In this embodiment, the second passage structure 9 is formed between the inner container 6 and the inner wall of the crushing chamber 1, the second type of material blocked by the classifying mechanism 5 can fall into the second passage structure 9, and the material which does not reach the specified particle size in the material subjected to the primary crushing treatment can directly fall into the second passage structure 9 after being blocked by the classifying mechanism 5, and can be crushed again.

Further, a plurality of second jet mechanism 8 all set up in second channel structure 9, carry out the regrinding's notion to the material that does not reach appointed granularity based on second jet mechanism 8, set up a plurality of second jet mechanism 8 in second channel structure 9 in this embodiment, on the one hand make by the material after hierarchical mechanism 5 blocks can directly fall to second channel structure 9 in, a plurality of second jet mechanism 8 of being convenient for directly carry out the regrinding to the material, on the other hand, can separate first jet mechanism 4 and second jet mechanism 8's flow field through the design of first channel structure 7 and second channel structure 9, avoid smashing the inside flow field confusion of room 1, make the crushing work mutual noninterference of the two.
