After the completion of food processing, it is also necessary to use certain food processing equipment to remove other impurities in the processed food. To 

this end, there are also grain cleaning and stone removal equipment specially designed to remove food impurities.

Failure and cause:

1. The thickness of the material layer is uneven in the width of the SLATE, the material deviation, and the stone discharge quantity of the two stone exits is 

obviously different

Reasons: uneven feeding, uneven width of the SLATE, abnormal movement of the screen body, uneven SLATE

2. Local materials cannot be suspended

Reasons: the concave surface of the SLATE is not uniform, the thickness of the material layer is not uniform, the movement of the screen body is abnormal, 

and the local fish scale hole is blocked

3. Air blows through partial materials

Reasons: The material layer is not uniform, the SLATE is locally raised, the air suction is too large, the screen body vibration and turbulence, the air suction 

hood and the SLATE joint surface local leakage

4. The stone discharged from the two stone outlets contains more or less food

Reasons: To the SLATE, the selected plate has fish scale holes blocked, or a blocked one is not blocked, the material deviation, the flow is too large, the 

suction volume is too small, and the stone collection area is formed

5. The stones in the material cannot be separated

Reasons: Abnormal movement of the screen body, too small suction volume, material suspension can not afford, flow is too large, material suspension 

can not afford, wrong speed

6. The material movement is abnormal, with vibration, turbulence and distortion

Reasons: ① Insufficient installation stiffness or loose cellar bolts or loose cellar bolts

② The connection between the eccentric transmission part and the swinging mechanism is loose

③ Bearing, rubber torsion or other parts damaged

④ The demolition and construction assembly is not correct or the replacement parts are not accurate enough to check the installation and maintenance 

part of this manual to eliminate it.

7. The machine doesn't work

Cause: ① The power supply or motor has a problem

② Motor reversal, resulting in the two connecting rod inside the positive, the reverse circle nut loose or the connecting rod end cap stuck, resulting in the 

machine spindle does not rotate to check the power motor, first stuck, and then open the connecting rod end cap, the internal positive, reverse nut tightened.

In order to avoid the above shortcomings, it is necessary to regularly check the troubleshooting of the equipment, including the key components of the food 

stoning equipment, the status of the food stoning equipment and the subjective status of the food stoning equipment when it is shut down.
