Ball Mill Seal

This article details ball mill sealing rings, which prevent leakage of materials/lubricants and block external contaminants, with types including contact, non-contact, and combined (most common) ones, made of materials like cast iron and nitrile rubber. It outlines the manufacturing process of combined sealing rings (metal skeleton casting, rubber lip vulcanization, assembly) and comprehensive inspection procedures covering raw materials, in-process, and finished products (sealing performance, dimensional accuracy, wear resistance). These ensure the rings meet reliability and durability requirements, extending ball mill maintenance cycles.
