The Shifting Geography of Feed Pellet Mill Components: Why Asia-Pacific Manufacturing Is Reshaping Global Supply

The global animal feed market crossed USD 420 billion in 2025. By 2034, projections place it north of USD 640 billion, with a compound annual growth rate just under 5%. Asia-Pacific already accounts for more than a third of global feed production, led by China, India, Vietnam, Indonesia, and Thailand. As the region’s livestock and aquaculture sectors scale up, so does demand for the machinery that turns raw ingredients into finished feed.

Less discussed, but equally significant, is the parallel evolution of the feed machinery component supply chain. Ring dies, roller shells, hammers, screens — the consumable parts that keep feed mills running — are increasingly sourced from specialized manufacturers in China and Southeast Asia. This is not simply a cost story. It reflects a convergence of manufacturing capability, metallurgical expertise, and proximity to the world’s fastest-growing feed markets.

Twenty years ago, ring die manufacturing was largely captive. Pellet mill OEMs produced their own dies, or sourced from a handful of established Western suppliers. Mill operators had few alternatives, and lead times for replacement dies often stretched to six weeks or more for markets outside Europe and North America.

The landscape today looks different. Independent ring die specialists — companies that focus exclusively on dies and wear parts — have emerged as a competitive alternative. These firms serve multiple OEM platforms (CPM, Andritz, FAMSUN, Bühler, Van Aarsen, and others), giving feed mill operators flexibility. More importantly, they have closed the quality gap.

A ring die manufactured in Liyang, Jiangsu province — China’s feed machinery manufacturing hub — can now match or exceed the performance of a die made in Europe. The difference is that it arrives in two weeks instead of six, at a delivered cost that is 20–30% lower. For a feed mill in Bangladesh running three shifts on tight margins, that difference is material.

Liyang Hongyang Feed Machinery, founded in 2006, sits at the center of this shift. The company produces ring dies and roller shells for virtually every major pellet mill model in operation, from SZLH250 to SZLH768 series machines. Its product portfolio covers diameters from 0.8mm shrimp feed dies to 18mm biomass pellet dies, serving poultry, livestock, aquafeed, and fertilizer applications.

Three factors distinguish Hongyang’s position in the market:
