JB/T 11255-2026Feed machinery - Roto-shaker grader (English PDF)

JB/T 11255-2026 is the English-translated version of 饲料机械平面回转分级筛.

JB/T 11255-2026 covers the roto-shaker grader used in feed machinery, a screening machine in which the sieve moves in a rotary motion in a flat plane to sort feed material into size grades. The document applies to this type of machine as a product of the feed processing equipment industry.

It is intended for manufacturers of feed machinery, feed mills that buy and operate graders, and laboratories or inspection bodies that assess such equipment. As the code carries /T, it is a voluntary industry standard. The Ministry of Industry and Information Technology issued it on 1 June 2026, and it takes effect on 1 December 2026. It replaces JB/T 11255-2011.
