PU Rubber Roller For Rice Hulling Machine and The Second Generation
Classification, structure and model of rubber roller:
At present, there are three kinds of hulling rubber roller,also known as three series, named wheel type, sleeve type and lap type respectively.
1. Wheel type: the center flange hole is used for positioning, and three or four bolt holes are fixed on two main shafts of the huller.
2. Sleeve type: it is positioned by 46o cone at both ends, and fixed on two spindles of the huller by the pin groove in the cone at both ends, which is fixed by taper and cap.
3. Lap type: it is positioned by the inner hole of lap son at both ends, and fixed on the two main shafts of the huller with the top fastening screws on the lap son at both ends.
General color: translucent milky white
Features: soft texture than rubber, the most wear-resistant, the highest price, because of the lower hardness, the rice milling rate is lower and the rice breaking rate is higher. Because polyurethane is different from rubber production process, the quality is not very stable, suitable for ordinary users;
| Type | Model(Inch) | Outer Diameter mm | Length mm |
| Wheel Type | LGL63(2 1/2″) | 152 | 63 |
| LGL100A(4″) | 182 | 100 |
| LGL100B(4″) | 222 | 100 |
| LGL152(6″) | 222 | 152 |
| LGL200(8″) | 225 | 200 |
| LGL200B(8″) | 255 | 200 |
| LGL254(10″) | 255 | 254 |
| LGL300(12″) | 268 | 300 |
| Casing Type | LGT355(14″) | 227 | 355 |
| LGT508(20″) | 255 | 508 |
