Palm oil chains are a specialized type of conveyor chain, primarily utilized for the comprehensive material transport of palm fruit-spanning the entire process from harvesting through pressing and refining. Their applications encompass various equipment, including feeders and conveyor systems. Structurally, these chains are categorized into three main types: straight-plate, bent-plate, and hollow-pin designs.
These chains feature medium-carbon alloy steel plates that undergo heat treatment to achieve a tensile strength of ≥1000 N/mm². The pins are crafted from alloy steel to ensure superior surface hardness and wear resistance, while the rollers and bushings are manufactured from low-carbon alloy steel and undergo precision machining to enhance their wear-resistant properties. Certain models are equipped with anti-fiber entanglement mechanisms, employing a combination of magnetic positioning, force-diverting rods, and sponge-block adsorption structures to provide effective protection against foreign debris. In 2024, the global market for palm oil chains was valued at approximately US$1,100 million and is projected to reach US$1,433 million by 2031. Key manufacturers in this sector include Donghua Chain Group and Qingdao Zhenghe Industrial; as a major producer and consumer, China plays a pivotal role in establishing a complementary industrial chain alongside Indonesia and Malaysia.
