1.The raw grain must be cleaned and moistened with water for 12 to 14 hours. The moisture content should be controlled between 13.5 and 14.5%.
2. Check whether the transmission of each transmission component is correct and flexible; whether the position of the operating handle, power switch, etc. is correct.
3. Adjust the flow rate, grinding roller spacing, etc. It is required to achieve uniform flow, parallel and synchronous grinding roller spacing, and the equipment should be silent before it can work.
4. Equipment start and stop
When starting the machine. The machine should be turned on first and then the material should be unloaded. After the material is in the grinding head bin, the operation should be carried out in the order of closing the grinding gate. When stopping the machine, the material should be stopped first and then the mill should be closed.
5. Flow adjustment
The flow control raw material should be small and the bran should be large. The flow rate can be adjusted by adjusting the gap between the flow plate and the feeding roller. The flow rate can be adjusted by rotating the handwheel screw.
6. Required gap for flour production
The raw grain is 0.15-0.35 mm, and the crushed material is 0.08-0.15 mm. Generally, the flour production requirements can be achieved after four to five passes. Pay attention to the uniformity of the load at each pass. The first pass consumes a lot of power, and the flow rate should be gradually increased in each subsequent pass.
(1) The motor has abnormal sound or odor;
(2) The motor housing temperature exceeds 70℃.
Common fault analysis and troubleshooting table | |||
Prone to failure | Occurrence location | Causes of the failure | Elimination methods |
Low flour yield | Raw material condition | Poor quality of wheat, more red wheat | Pay attention to wheat matching |
Large loss of raw material | Wheat grains in the scraps | Recover wheat grains from waste materials | |
High moisture content of wheat before milling | Difficult to scrape off the bran and screen the material | Reduce moisture content | |
Low moisture content of wheat before milling | Bran is fragile and the powder is of poor quality | Increase moisture | |
Insufficient tempering time | Poor moisture adjustment | Ensure wheat tempering time | |
Uneven feeding | Low grinding efficiency of the mill | Adjust the material gate to make it uniform | |
Flour has a bad texture | Raw material condition | Wheat contains a lot of impurities | Control the quality of wheat harvest |
Abnormal cleaning equipment | Screen surface is blocked, the stone remover does not work properly, and the gap of the thresher is large. | Clean the screen surface in time, adjust the stone remover, clean the stone remover screen surface, check the balance of the screen boat movement, and adjust the gap of the thresher | |
Operation | Too much flow | Control flow | |
Unqualified coarseness and fineness | Raw material condition | Too much hard wheat | Rationally match wheat, adjust the wheat entering the mill, and extend the wheat tempering time |
Low flow rate | Insufficient powder extraction flow | Increase flow | |
Poor flour color | Raw material condition | Too much red hard wheat, the wheat entering the mill contains a lot of impurities, and there is a lot of diseased and rotten wheat | Control wheat quality |
Wheat before milling | Low moisture in wheat, and the bran is fragile | Adjust the moisture content of wheat entering the mill | |
Strong sieving effect | The gap between the powder extractor brush and the screen surface is small, and the spring is pressed dead after the rolling distance | Adjust the gap between the brush and the screen surface, and adjust the spring pressure | |
Unqualified flour moisture | Moisture adjustment | Unqualified moisture entering the mill | Pay attention to moisture adjustment |
Operation | The grinding mouth is too tight, and the moisture consumption is large | Adjust the operation balance | |
High bran content | Raw material | The moisture is too high (too low), and the wheat tempering time is not enough | Strengthen moisture adjustment and ensure the wheat tempering time |
