Best PU Rice Rubber Roller,rice mill rubber rolls with cast iron or aluminum

SALIENT FEATURES

Salient features to get maximum output from Rubber Dehusking Rolls. The life of rolls is not only governed by its quality but also several other factors such as variety and type of paddy (Short/Long, Raw/Parboiled), climatic conditions, Peripherals speed of Rolls distribution of paddy, moisture contents of paddy, dehusking percentage of paddy, clearance between the rolls cleaness of the paddy, cooling arrangement of rolls, eccentricity in shaft and operators skill. Some of these parameters e.g. Variety of paddy and climatic conditions are beyond the control of Rice millers but others can be controlled very well for which, following steps must be taken into account to get maximum output for rubber rills.

PERIPHERAL SPEED OF ROLLS

The Rolls rotate at different RPMS and in opposite direction. Normally the peripheral speed of the adjustable roll is about 25% slower than the fixed roll. Hence the former wears slower comparatively even as the rolls are interchangeable in position (Fig A). From above illustrations, it is clear that the pair of rolls must be changed at a time rather that the individual roll.

AGE OF ROLLS

Rubber rolls deteroiates gradually as shown in Fig. B below, hence they can be stored only for limited period and yet it is recommended that they should be utilized between 3 and 6 months after production. Therefore, rice millers should not store rubber rolls more than one year, rather a continuous supply should be maintained in order to receive optimum efficiency.
