The Role of Babbitt Alloy Bearings in Milling Machines
Babbitt alloy is widely used in the construction and building materials machinery industry, especially in sliding bearings for milling machines and ball mills. It serves as a crucial component that provides anti-vibration, load distribution, and self-lubrication properties. In cement plants, during equipment maintenance, ZChSnSb11-6 type tin-based alloys are commonly chosen due to their ability to perform under harsh conditions such as high dust levels and heavy loads. Shangshui Metallurgical Non-ferrous Metals Co., Ltd. has focused on understanding the specific functions of babbitt alloys in milling machines, ensuring optimal performance and durability.
In grinding machines, babbitt alloy bearings are subjected to abrasive wear caused by the grinding process. This includes ploughing, micro-pressure-induced peeling, and fatigue fracture. To enhance wear resistance, the babbitt alloy must possess both sufficient toughness and high hardness. Improving the material's toughness increases its resistance to peeling and enhances its ability to withstand fatigue wear. Common babbitt alloys include tin-based types with over 54% tin, such as the 11-6, 8-8, and 4-4 models, each designed for different operational demands.
In ultra-fine grinding machines, babbitt bearings and grinding rings work together as an integrated system. They are essential components responsible for crushing and grinding materials under high pressure. These parts can be adjusted to optimize the grinding effect, improving efficiency, output, and reducing the consumption of the babbitt layer. Additionally, they protect the mill barrel from direct impact and friction, extending its service life. The gap between the bearing bush and the grinding roller also helps control the particle size of the final product, ensuring desired fineness and yield.
Shangshui Metallurgical Non-ferrous Metals Co., Ltd. continues to align with advancements in mining and construction machinery. The company focuses on energy-efficient and environmentally friendly production methods in the development of babbitt alloys. This approach not only meets technological demands but also supports the mining industry in achieving safer, more efficient, and cleaner operations. By increasing the technological value of their products, they aim to provide higher-quality solutions for global markets.
Despite the growing use of babbitt alloys in heavy machinery like mills and ball mills, many users still lack proper understanding of how these bearings operate. The choice of tin-based babbitt bushings plays a critical role in determining the machine’s operational lifespan and reliability. Proper maintenance and selection of babbitt alloys are essential to ensure smooth and long-term performance of the equipment.
