The milled rice polishing machine is core equipment for modern rice milling plants, specially designed to polish brown rice and milled white rice, removing bran powder, fine impurities and surface burrs. It improves rice brightness, smoothness and storage quality, widely matched with complete rice processing production lines. This machine is essential for medium‑large rice factories to produce high‑grade polished rice for commercial sales and export markets.

Common Faults & Quick Solutions
| Fault Phenomenon | Cause Analysis | Troubleshooting Solution |
|---|---|---|
| Rice polishing uneven, partial dim grains |
Uneven water mist spraying, blocked water nozzle, abnormal feeding volume |
1. Clean blocked water nozzles 2. Adjust water‑mist pressure and feeding speed 3. Check atomizer device |
| High broken‑rice rate after polishing |
Excessive polishing pressure, worn polishing roller, too high rotating speed |
1. Reduce polishing pressure and rotating speed 2. Replace worn polishing roller 3. Control rice feeding quantity evenly |
| Machine vibrates abnormally with loud noise |
Loose fixing bolts, unbalanced roller, foreign matter inside polishing chamber |
1. Tighten all fixing bolts 2. Balance the polishing roller 3. Clean foreign impurities inside the machine |
| Water mist not spraying normally |
Water pump failure, blocked water pipeline, insufficient water pressure |
1. Inspect and repair water pump 2. Dredge blocked water pipeline 3. Adjust water supply pressure |
| Rice discharging slowly or blocked inside the machine |
Excessive feeding, blocked discharge outlet, sticky bran residue |
1. Reduce feeding volume 2. Clean discharge outlet and bran residue 3. Improve ventilation inside the polishing chamber |
