An extractor chain with a 250 mm pitch is a type of chain used in solvent extractors to facilitate the movement and processing of material. The “250 mm pitch” refers to the distance between consecutive chain links, which is 250 millimeters. This specification determines the spacing and the overall size of the chain, affecting the capacity and efficiency of the extractor. In solvent extractors, this chain helps transport material through various stages of the extraction process, ensuring smooth and continuous operation. The design and pitch size are critical for achieving optimal performance and reliability in handling large volumes of material.
