The objective in milling rice is to separate the rice husk from the grain. If possile, the grain should not be broken. Thus Detchai Rubber rollers have been designed to meet the the need of each type of grains in different rice mills. The strength is in the range of 87 + 5 IRHD Shore A. Besides the size of the roller is an important factor for specifying the rotation speed (rpm.). The size 10" x 10" (254mm. x 254mm.) . This is the standard size with the suitable rotation speed to cause the slip stick condition. Many customers misunderstand that if the velocity is increased more grains can be obtained. But in fact is increased the slip stick condition is reduced because the rubber surface's molecule is wavy across the surface are and the friction between the rubber surface and the millingstone is reduced. The percentage of the husks peeling off is thus reduced.
