20 inch NBR rubber roll for rice sheller

 

20 inch NBR rubber roll 

 

Advantages:
1. Strong bonding between rubber roll and drum
2. Ensure high degree of heat resistance and durability
3. High peeling efficience at minimum broken rice to be attained by its well balance of elasticity, hardness and abrassion resistance.
4. Maximum hulling rate with lowest breakage and better output.

 

Useful Tips:

1. Optional of Rice Huller Rubber Roller: For the choice of  the black, brown and white rubber roller with  hardnes s shore A 90^oC and 95^oC, it should be according to the type of rices, climate conditions, and different seasons.Try to avoid to use the single roller,  the recommended way is higher hardness for fast roller, lower hardness for slow rollers.

 

2.Temperature and Hardness Control: The proper hardness is shore A 82-86^oC, and the temperature is below 50^oC. When the temperature reaches above 60^oC,  the hardness of roller should be reduced 4-8^oC

 

3. Alternative use of rubber roller for rice mill is recommended: A: It can increase the usage life of roller and quantity of dehusking rice.

B: Each roller has break time during the working, which is good for recoving the function of rubber, adjusting the speed difference upon different diameters, and controlling the temperature effectively.

 

4. Two rollers should be at the same level to keep the space equal.

 

5. The paddy inputting should keep the balance.

 

6.  Keep the rate of the re-hulling under the limitation

 

7. Storage:

A: Avoid the direct sun shine and soaked in the rain and snow.

B: Away from the heating device about 1.5m. 

C: Store in dry and clean place, away from acid, alkali, salt, oil and organic solvent.

D. Keep the room temperature 10-30^oC, comparative moisture 50-80^oC 

E. Keep in vertical position,horizontal is not allowed.

F. No other materials pressure on it, no hitting to avoid deformation and damage.
