This article details ball mill bearings, which support the cylinder, bear heavy loads, and reduce friction, with key types including spherical roller bearings, double-row tapered roller bearings, and sliding bearings (Babbitt metal bearings), each suited to different mill sizes. It focuses on the manufacturing process of spherical roller bearings, covering inner/outer ring production (forging, heat treatment, precision grinding), roller and cage manufacturing, and assembly. Additionally, it outlines comprehensive inspection processes from raw materials to finished products (material composition, hardness, dimensional accuracy, rotational precision, life tests, etc.) to ensure they meet heavy-load, long-term operation requirements of ball mills.
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.
This article elaborates on ball mill feeders, which uniformly and stably feed materials into ball mills, with common types including screw, belt, vibrating, and plate feeders, each suited to different materials and scenarios. It details the manufacturing process of vibrating feeders (a typical type), covering key component production (trough, vibrator, spring supports) and assembly. Additionally, it outlines comprehensive inspection processes from raw materials and components to assembly and final acceptance, ensuring feeders meet performance requirements like uniform feeding, wide adjustability, and high reliability, thus supporting efficient and stable operation of ball mills.
This article details ball mill couplings, which transmit torque, compensate for installation errors, and buffer impacts, with key features like high strength and wear resistance. It covers common types (elastic pin, gear, diaphragm, universal couplings) and focuses on the manufacturing process of gear couplings, including raw material pretreatment, blank processing, finish machining, surface treatment, and assembly. Additionally, it outlines comprehensive inspection processes from raw materials to finished products (dimensional accuracy, heat treatment, dynamic balance, etc.) to ensure reliability for long-term heavy-load operation of ball mills.
This article details ball mill bearing blocks, which bear radial/axial loads, ensure shaft stability, and feature materials like HT300, QT450-10, or Q355B. It covers manufacturing processes for cast (molding, pouring, aging, machining) and welded (blanking, welding, machining) types, plus full-process inspections (raw materials, blanks, in-process, final products) to guarantee dimensional accuracy, strength, and reliability, meeting heavy-load, continuous operation needs.
This article details the functions and structure of ball mill gearboxes, which need high load-bearing capacity, transmission efficiency and reliability. It also covers manufacturing processes of housings, gears and shafts, assembly procedures, and full-process inspection from raw materials to finished products, to meet the heavy-load and continuous operation requirements of ball mills.
