White rice graders are used to classify and grade milled rice by different particle size according to length or thickness. This machine is also suitable for grading other grain types.
The white rice grader uses a large-scale flat gyration motion in the sieve body to separate rice into different levels, including common rice, broken rice, bran ball, and bran. Rice in different granular sizes passes through the sieve plates of a related diameter. The sieve plates also feature jump balls to prevent mesh blockage and improve the screening effect.
