Self Lubricating Stainless Steel Radial Spherical Joint Plain Bearing
Grinding mills are machines used to break solid materials into smaller pieces by grinding, crushing, or cutting. They are commonly used in the mining, construction, and chemical industries to reduce the size of materials such as rocks, minerals, or grains.

Metal-polymer self-lubricating bearings are made of a sintered porous bronze backing with a PTFE polymer layer. This combination provides mechanical strength, excellent thermal conductivity, and low friction even under dry conditions. The PTFE layer ensures smooth operation with minimal wear and can function effectively with or without lubrication.
Main Product
Structure
1. PTFE/Fibre mixture (0.01–0.03mm thick) creates an initial transfer film that protects the mating surfaces and reduces friction.
2. Sintered bronze powder (0.20–0.35mm thick) enhances thermal conductivity and acts as a reservoir for the PTFE layer.
3. Low-carbon steel base offers high load capacity and efficient heat dissipation.
4. Copper/Tin plating (0.002mm thick) improves corrosion resistance and durability.

There are various types of grinding mills, each designed for specific applications. Some common types include:
1. Ball mills: These mills use balls made of steel or other materials to grind the material. The balls are placed inside a rotating drum, which causes them to collide with the material, resulting in size reduction.
2. Rod mills: Similar to ball mills, rod mills also use rods instead of balls for grinding. The rods are placed inside a rotating drum and tumble the material, breaking it down into smaller pieces.
3. Vertical roller mills: These mills have a vertical orientation and use rollers to grind the material. They are often used in cement and mining industries.
Grinding mills can be powered by electricity, diesel, or gas engines. They can also be operated manually in smaller-scale operations. The choice of grinding mill depends on factors such as the material being processed, desired particle size, and production capacity.
