Bucket bolts, also known as ball mill liner screws, are designed to secure the liners inside a ball mill. These bolts are crucial for the stability and safety of the mill operation. They are typically made from stainless steel (304/316), carbon steel, or alloy steel, which offer different properties such as corrosion resistance, strength, and durability.
Stainless Steel (304/316): Offers superior corrosion resistance and is suitable for moist or corrosive environments. The 316 grade has additional molybdenum, providing even better corrosion resistance, especially in marine applications.
Carbon Steel: Provides good strength and is the most common material for bolts. It may require additional surface treatments like galvanizing for increased corrosion resistance.
Alloy Steel: Offers enhanced strength and durability. It is often used in high-stress applications where high tensile strength is required.
Advantage:
High Strength: Manufactured from high-strength materials to withstand the harsh conditions inside a ball mill.Customizable: Available in various head shapes, lengths, and diameters to fit specific mill liner designs.Corrosion Resistance: Stainless steel options provide excellent resistance to corrosion, especially in moist or corrosive environments.Heat Treatment: Many bucket bolts undergo heat treatment processes to enhance their strength and durability.Safety: Designed to reduce the risk of mill shutdowns due to liner failure.
Scope of
application
Ball Mills: Used in ball mills for securing liner plates.SAG/AG Mills: Employed in SAG and AG mills for similar purposes.Rod Mills: Utilized in rod mills for
securing the internal components.
