O series round link chain for underground mining is a specific type of chain used in mining operations, particularly in underground coal mines. It is designed to withstand the harsh conditions and demands of underground coal mining environments. Our chain typically consists of interconnected round links made from high-strength steel. The round links are designed to provide durability and resistance to abrasion, corrosion, and fatigue, which are common challenges in underground mining operations. They commonly used for various applications in underground mining.
Key Features / Benefits
. Sizes available range from 14x50 to 48x152.
. The enhanced version improves fatigue life by approximately 300%.
. The Cor-O version offers approximately 350% greater resistance to stress corrosion.
. The ultra-flat link chain series ensures extended wear and lifespan.
Key Benefits
Superior High Tensile Strength: These chains are engineered to withstand tremendous tensile forces. This is critical for transporting heavy bulk materials over long distances and uphill, especially in underground and open-pit mining operations.
Superior Durability and Wear Resistance:
High-quality Materials: Made from special alloy steels, they are typically subjected to specific heat treatments (such as through hardening or case hardening) to provide high hardness for enhanced wear resistance and high toughness to resist impact loads.
Wear Resistance: Their rugged steel construction makes them highly resistant to the abrasive nature of ore, rock, coal, and other mining materials.
Impact resistance: Designed to absorb large shock loads without deforming or breaking, which is common when handling large bulk materials.
Reliability in harsh environments:
Dust, dirt and moisture resistance: Its simple open structure allows it to operate effectively in high dust, high stain and high humidity environments that severely degrade the performance of other types of chains.
Temperature resistance: It can generally withstand a wide range of operating temperatures.
Positive engagement: The round link chain has a positive mesh with the sprocket, ensuring no slippage, thereby providing a steady material flow and efficient power transmission.
Self-cleaning characteristics: The rounded and smooth surface and gaps between the links give it a certain self-cleaning function, preventing excessive material accumulation, which can avoid jamming or uneven wear.
Easy assembly and maintenance: Although heavy, its design generally allows relatively simple assembly and replacement of individual links or components, which helps reduce maintenance time.
Applications
Scraper conveyor: This is its most prominent application. Round link chain is the traction element of a face conveyor (also known as a chain conveyor or chain conveyor) used to transport coal, ore, and other bulk materials along a conveyor trough, especially common in underground longwall mining.
Face Loader: Used in conjunction with a face conveyor to load excavated material.
Plow Systems: In some continuous mining operations, round link chain is used with plows to continuously mine and load coal or other soft minerals.
Face Conveyors (AFCs): These are heavy-duty chain conveyors that form the backbone of longwall mining, transporting coal from the shearers to the main roadway conveyors. Round link chain is a critical component in these high-capacity, high-stress applications.
Hoisting and Lifting (Auxiliary): Although less common in main shaft hoisting, specialized high-grade round link chains may be used in some auxiliary lifting applications or chain slings for heavy mining equipment.
Ash Handling Systems: In power plants associated with mining operations, round link chains may be used in conveyors to handle abrasive and often hot ash.
