The traditional pulverizer adopts a mode of feeding in a first-stage crushing chamber and discharging in a last-stage crushing chamber, namely only one feeding hole and one discharging hole are needed. However, when the user has a high requirement on the precision of the powder, the conventional pulverizer needs to screen the powder falling from the discharge port and feed the unqualified powder into the first-stage crushing chamber again for crushing, so that the operation process is complex and the efficiency is low. According to the preferable technical scheme of the embodiment, the first discharge port 7 and the second discharge port 8 are respectively arranged above and below the last-stage crushing chamber, and when the requirement of a user on the precision of powder is not high, the powder is covered by the upper discharge port cover plate 21 above the first discharge port 7, so that the crushed powder falls out through the second discharge port 8. When the requirement of a user on the precision of the powder is high, the upper discharge port cover plate 21 is opened, the first discharge port 7 is connected with the powder concentrator, the second discharge port 8 is closed, and the crushed fine powder is blown upwards by utilizing high-speed wind power generated by the crushing cavity, so that the fine powder can be selected from the first discharge port 7, and the unselected powder falls into the crushing cavity to be continuously crushed. And circulating the steps until all the materials are crushed and the required precision is achieved.
According to the preferred technical scheme of the embodiment, the first discharge port 7 and the second discharge port 8 are respectively arranged above and below the last-stage crushing chamber, when the precision requirement of the powder is high, a user does not need to sieve the falling powder independently, and powder which does not meet the precision requirement does not need to be repeatedly input into the first-stage crushing chamber, so that the operation process can be simplified, and the crushing efficiency is improved.
According to a preferred embodiment, a discharging adjusting opening 22 is further arranged below the Nth stage crushing chamber in the crushing cavity, and an adjusting handle 23 for adjusting the discharging amount is arranged at the discharging adjusting opening 22, as shown in fig. 2. Preferably, the adjusting handle 23 comprises a steel plate and a handle, and the adjusting handle 23 is clamped on the side wall of the blanking adjusting opening through the steel plate. Specifically, the inclination angle of the steel plate can be adjusted by rotating the handle. When the steel sheet is in horizontal position, unloading regulation mouth 22 closes completely, and when the inclination of steel sheet was anticlockwise crescent gradually, the opening of unloading regulation mouth gradually increased, and when the steel sheet was in vertical position, unloading regulation mouth 22 was all opened.
The preferred technical scheme of this embodiment is through adjustment handle 23 regulation load size, and the dwell time of adjustable material in the host computer to the granularity size of control ejection of compact powder, so that the pulverizer of this embodiment can satisfy the different demands of user to granularity size.

In the discharging process, the airflow generated by the powder is large, and the second dust suction port 25 cannot capture the dust in the powder. In the preferred technical scheme of the embodiment, the blanking dust removing bin 24 is arranged between the blanking adjusting port 22 and the second discharge port 8, and the blanking dust removing bin 24 has a larger size, so that the air speed of the falling materials of the blanking adjusting port 22 can be reduced, and the second dust collecting port 25 can capture dust in powder materials.
According to a preferred embodiment, a hopper 26 is detachably connected above the feed opening, and a first dust suction opening 27 is provided on a side wall of the hopper 26, as shown in fig. 2, to reduce dust of the material fed through the hopper 26 through the first dust suction opening 27. Based on the requirement of the user on the granularity of the powder, the number of the crushing chambers is selected, and therefore the material inlet is selected. For example, if the first stage crushing chamber 11 is selected for feeding, the hopper 26 is connected to the first feed opening 15; when the second-stage crushing chamber 12 is selected for feeding, the hopper 26 is connected to the second feeding hole 16; and so on.
According to a preferred embodiment, the inlet of the hopper 26 is provided with a first blanking plate 28 and a second blanking plate 29, which are inclined, as shown in fig. 2. Preferably, the first blanking plate 28 and the second blanking plate 29 are inclined in opposite directions, and the inclination angles of the first blanking plate 28 and the second blanking plate 29 are greater than 40 °.
