1.雜音：出現這種現象的原因主要有三方面，一是轉子與側板之間滯留所輸送的粉粒物料；二是機殼與轉子間隙小造成其接觸；三是機殼內表面有粉料附著、粉料物融化則轉子與機殼這間間隙消失。解決雜音現象的方法從側面絲堵部位進行氣體沖洗；二是擴大間隙、使其達到恰當的間隙；三是縮小轉子端面面積。

1. Noise: There are three main reasons for this phenomenon: firstly, the powder material conveyed between the rotor and the side plate is stuck; Secondly, the small gap between the casing and the rotor causes contact; Thirdly, if there is powder attached to the inner surface of the casing, and the powder melts, the gap between the rotor and the casing disappears. The method to solve the noise phenomenon is to perform gas flushing on the side plug area; The second is to expand the gap and achieve an appropriate gap; The third is to reduce the area of the rotor end face.

2.振動：出現這種現象的原因主要是鏈條過緊，適當松一下鏈條即可。

2. Vibration: The main reason for this phenomenon is that the chain is too tight. Simply loosen the chain appropriately.

3.供料量不足：一是由于泄漏氣體的作用使粉粒物料下落受阻礙；二是粉粒體物料的容重不同于設計值。對于第一種故障采用抽氣措施即可解決；第二種提高轉速，使其達到適宜轉速。

3. Insufficient material supply: Firstly, due to the leakage of gas, the falling of powder particles is hindered; The second reason is that the bulk density of powder and granular materials is different from the design value. For the first type of malfunction, air extraction measures can be used to solve it; The second method is to increase the speed to reach the appropriate speed.

4.卡料：此故障主要由配管不當、使機殼變形及溫度上升、超過間隙設計的溫度；解決方法是在供料器的正上方或正下方使用軟管；擴大間隙使其達到適宜間隙。

4. Material jamming: This fault is mainly caused by improper piping, deformation of the casing and temperature rise, exceeding the temperature specified in the gap design; The solution is to use a hose directly above or below the feeder; Expand the gap to achieve the appropriate gap.
