Through the setting of the temporary storage device 40, the material backblown by the pulverizing device 10 can enter the temporary storage device 40 and be received by the temporary storage device 40, thereby avoiding leakage caused by the backblowing of the material to the conveying device 30.

[0043] It can be understood that the conveying device 30 can be any conveying equipment that can convey granular materials, such as a screw conveyor, a conveyor belt, a blower, etc.

The collector 70 is used to collect the fine material. Specifically, the material in the pulverizing chamber 11 will enter the classifying wheel 60 after being pulverized and refined. The finer particle material will enter the inside of the classifying wheel 60 and enter the collector 70 for collection after passing out.

Specifically, the second air duct 53 can provide a certain driving force for the conveying of the material by blowing air into the conveying device 30, thereby improving the conveying efficiency of the material and preventing the conveying device 30 from being blocked by the material.

[0054] In this embodiment, the second air duct 53 is communicated with the interior of the cylinder 31 of the conveying device 30 to blow air to the material inside the cylinder 31 toward the temporary storage device 40 .

[0055] In some embodiments, Figure 1-2 As shown, the temporary storage device 40 includes a temporary storage tank 41 and a conveying pipe 42. The temporary storage tank 41 is connected to the discharge end of the conveying device 30, and is used to receive the material output from the discharge end of the conveying device 30. The conveying pipe 42 is connected to the temporary storage tank 41 and the crushing chamber 11, and is used to convey the material in the temporary storage tank 41 to the crushing chamber 11. Specifically, the material conveyed by the conveying device 30 will enter the temporary storage tank 41 for temporary storage, and then be conveyed to the crushing chamber 11 through the conveying pipe 42. The material backwashed by the crushing chamber 11 can enter the temporary storage tank 41 through the conveying pipe 42, and will not enter the conveying device 30 in the reverse direction, thereby preventing the material from leaking from the conveying device 30.

[0056] It can be understood that the conveying pipe 42 can convey the material by being inclined toward the pulverizing device 10, or by providing a driving structure such as a screw rod 32 inside to convey the material.

[0057] In some embodiments, Figure 1 As shown, the air supply device 50 further includes a third air duct 54, which is connected to the induced draft module 51 and the conveying pipe 42.

Specifically, the induced draft module 51 passes the gas into the conveying pipe 42 through the third air duct 54, and then drives the material in the conveying pipe 42 to be conveyed to the crushing chamber 11, thereby realizing the conveyance of the material to the crushing chamber 11.

[0059] In one embodiment, Figure 1 As shown, the induced draft module 51 includes an induced draft fan 511 and an air inlet channel 512. The induced draft fan 511 is connected to the collector 70, and the first air duct 52 is connected to the air inlet channel 512. Specifically, the induced draft fan 511 evacuates air from the collector 70, so that the gas can enter the distribution chamber 131 through the first air duct 52.
