[0049] IV. Discharging process
[0050] 1. The crushed feed is moved to the screen plate 5 under the pushing of the blowing area of the fan blades 81. The feed particles meeting the particle size requirements can pass through the screen plate 5 into the discharge chamber 5, while the larger particles that do not meet the particle size requirements are left in the crushing chamber 4 for further crushing.
[0051] 2. The discharge chamber 5 is connected with the fan 3 and the discharge port 6. After the fan 3 is started, the negative pressure is generated by suction to suck the crushed feed that has passed through the screening out of the discharge port 6, so as to realize automatic discharging. During the discharging process, the discharging condition can be observed. If it is found that the discharging is not smooth or there is a blockage phenomenon, the machine should be stopped in time to check whether the screen plate 5 is blocked or other parts are malfunctioning.
[0052] V. End operation

[0054] 2. Disconnect the motor from the driving shaft 84, and clean the residual feed in the feed suction port 7 and the suction pipe 72 to prevent the residual feed from deteriorating and affecting the next use.
[0055] 3. Open the upper housing 1, check whether there is residual feed or sundries in the crushing chamber 4, and clean them if there are. At the same time, check the wear condition of each part, such as the crushing disc 83, the hammer pieces 87, the toothed plate 9, the fan blades 81, etc. If it is found that the parts are severely worn, record them in time and arrange for replacement or repair.
[0056] 4. Store the crusher in a dry, ventilated and safe place to avoid direct sunlight, humid environment or other objects from colliding and damaging the equipment.
[0057] Preferably, the side edge of the side of the fan blades 81 facing the feed suction port 7 is an inwardly inclined bevel, forming a feeding area facing the feed suction port 7. The material sucked in enters the crushing chamber 4 from the bevel area.
[0058] Preferably, a slidable sliding plate that can open and close the opening between the feed suction port 7 and the upper housing 1 of the crushing chamber 4 is arranged at the opening.
