1. Paddy Rice Destoner

There is a lot of grain in the stone

1. Take out the slate and seal the fish scale holes on the selected plate.
2. The material is off-center.
3. The material flow is either excessive or insufficient.

Stone difficult to discharge

1. Irregular cutting.
2. The slate width is not level.
3. Uneven movement of the slate.
4. Severe vibrations in the machine.

Too much sand in the rice

1. The sieve body’s motion is abnormally pronounced.
2. Inadequate suction volume, causing the material not to suspend.
3. Incorrect speed setting.

2. Paddy Rice Husker

The husking rate is low

1. Oversized feed.
2. Excessive moisture content in the raw grain.
3. Insufficient pressure on the rubber roller.

Breakage rate is high

1. Excessive pressure between the rollers.
2. Excessive recycling of paddy rice.

Sudden stop

1. Rice obstruction in the rubber roller.
2. Obstruction between the rubber rollers.

3. Gravity paddy separator

Strong vibration or big noise

1. Loose anchor nuts and fasteners.
2. The lock nut on the draft rod is not secure.
3. Inaccurate positioning of the two sets of supports or a missing bearing.
4. The outer bolt connecting the separation box and support body is not tightened, resulting in excessive clearance between the hinge and the pin.
5. The drive belt is overly tense, and the motor shaft is not parallel to the spindle’s centerline.
6. Collisions between the inlet/outlet and the material pipe occur.

Different layer separations are not even

1. Uneven coverage of paddy rice.
2. Loose tightening screws on a specific layer of the screen surface, leading to the separation plate detachment.
3. Feed impact, causing large husks to divert to the side.
4. Excessive material flow.
5. Inadequate angle.
6. Loose fasteners in the connection between the support body and the drafting, the small shaft support seat frame, and the box body, disrupting the parallelogram and causing disorder.

4. Rice Mill

Production decrease significantly

1. The screw propeller exhibits significant wear.
2. Severe wear is observed in the sand roller.

Broke rice too much

1. Uneven connection of the rice sieve.
2. Poor connection between the sand roller and the propeller.

The precision of the finished product is uneven

The sand roller exhibits significant wear.
