1. Problems with the motor of Shimo sesame paste machine: high temperature is one of the main causes of motor damage. Due to lack of oil in bearing, dirt in bearing, bearing damage, motor overload, etc.

2、整理篩毛病:①整理篩振動大或篩框晃動，原由于螺栓或木楔松動。②砂石中帶有麥料，新型石磨芝麻醬機，原因是排石嘴內部風門小，或篩面傾角不合適。③小麥被打碎過多，小型石磨芝麻醬機，原由于打麥裝置齒板與篩片空隙太小，篩孔過大或損壞。

2. Problems of finishing screen: ① the vibrating of finishing screen or shaking of screen frame is caused by loose bolts or wedges. ② There is wheat material in the sand and stone. The new type of stone grinding sesame paste machine is due to the small air door inside the stone discharge nozzle or the improper inclination angle of the screen surface. ③ There are too many broken wheat in the small stone grinding sesame paste machine, because the gap between the tooth plate and the sieve plate of the threshing device is too small, the sieve hole is too large or damaged.

3、石磨芝麻醬機螺旋攪拌器毛病:①出糧口不排糧，原由于電機轉向不對，出料口阻塞，石磨芝麻醬機，攪拌器葉片開裂等。②攪拌器軸不轉，原由于喂料過多，傳動帶打滑等。

3. Problems of screw mixer of Shimo sesame paste machine: ① the grain outlet does not discharge grain, because the motor turns wrong, the outlet is blocked, the blades of Shimo sesame paste machine and mixer are cracked, etc. ② The agitator shaft does not rotate because of too much feeding and the drive belt slipping.

4、石磨芝麻醬機毛病:①機身晃動，應擰緊磨頭與機架聯接螺栓。②產值下降，應調緊彈簧，保證磨輥兩端空隙一致，對磨損的磨齒進行修理。③面粉溫度高，應調松磨輥;如磨輥磨損嚴重應修理或替換;機溫高時就停機散熱。④不出麩皮，原由于主軸轉向不對，篩框密封不嚴或篩網破損。⑤不出粉或出粉少，原由于篩阻塞。

4. Problems of stone mill sesame paste machine: ① the machine body shakes, so the connecting bolts between grinding head and frame should be tightened. ② When the output value decreases, the spring should be adjusted to ensure the gap at both ends of the roller is consistent, and the worn grinding teeth should be repaired. ③ If the flour temperature is high, the roller should be loosened; If the roller is seriously worn, it should be repaired or replaced; When the temperature of the machine is high, it will be shut down for heat dissipation. ④ No bran, because the main shaft steering is not right, the screen frame seal is not tight or the screen is damaged. ⑤ No powder or less powder, the reason is that the screen is blocked.

5、石磨芝麻醬機閉風器毛病:閉風不好，面袋可能被吸上。原由于各銜接處漏風，葉輪磨損等。葉輪磨損時可在外緣加裝一塊橡膠板。

6. Problems of cloth filter: ① there is a lot of dust in the room, which is caused by the loose dust collector of the distribution box, the cloth filter is not tied tightly, and the air leakage of the air duct. ② There is too much flour in the cloth filter barrel. Due to the large air volume, the connection at the lower end of the powder collector leaks or wears through, and the gap between the closed air impeller and the shell is large.

7、石磨芝麻醬機電器毛病:①機組不能發動，常見原由于電壓過低，配電線缺線，線路接觸不好，操控回路斷線，保險絲熔斷等。②電機不能發動，原由于電機操控回路接觸不好或斷線，溝通接觸器線圈燒壞等。

7. Electrical problems of Shimo sesame paste machine: ① the unit can't be started, the common reasons are low voltage, lack of distribution line, poor line contact, broken control circuit, fuse, etc. ② The motor can not be started because the motor control circuit is not well contacted or broken, and the coil of communication contactor is burnt out.
