Engineering detail drawing showing the cross-section of a rice hulling roll used in grain processing equipment. The component features a cylindrical design with a 257mm diameter and 54.3mm thick rubber outer layer bonded to a 5mm thick cast iron drum core. The drawing includes both plan and sectional views, detailing mounting holes configurations for different mill compatibility: Satake mills (3 holes at 120° spacing) and Cimbria mills (4 holes pattern). The roller’s total length is 255mm with key internal diameters including Ø180mm, Ø204mm, and Ø240mm. Both samples from Rice Engineering and BERNAS (Beras Nasional Berhad) are documented with specific dimensional variations. The engineered rubber compound provides the optimal friction coefficient for rice hull removal while maintaining durability under industrial processing conditions.
