This paper discusses the founding of mathematical model of centrifugal probability ballast cleaner,and combining with the model,introduces the mixed discrete optimal design method,and hence offers a practical reliable optimal method for centrifugal probability ballast cleaner.

The high-speed video system and the image processing method were used to experimental study on the screening process of agricultural materials and the relationship between the major working parameters and materials passage probability was received through the range analysis.
