More About H78 Mill Chains

H78 Mill Chain is a malleable-cast mill chain designed for heavy-duty conveying and drive systems in abrasive environments. H78 Chain has adopted the common name H78 Mill Chain because it has been one of the most commonly found chain types in the mill and lumber industry for 70+ years. Specifically, our H78 Mill Chain has an ultra-high working load of 2,810 LBS and a tensile strength of 22,220 LBS, making it capable of handling some of the toughest applications out there. We also supply the H78 chain off the shelf with stainless steel cotter pins (cotter keys) for environmental, aggregate, and wastewater applications. The H78 Mill Chain is designed to run on the same sprockets as its steel counterpart, "WH78 welded steel chain," meaning if you are making a switch to the cast version, no sprocket replacement is necessary.

H78 Mill Chain Applications

The H78 Mill Chain is a specific type of roller chain commonly used in various industrial applications. It is known for its durability, strength, and resistance to wear and abrasion. Here are some typical applications where the H78 Mill Chain is utilized:1. Sawmills: H78 Mill Chains are extensively used in sawmills for conveying logs, lumber, and other materials throughout the production process. They are employed in log decks, transfer tables, and lumber handling equipment.2. Paper mills: In the paper manufacturing industry, H78 Mill Chains are employed in various stages of the production line. They are used for transporting paper rolls, pulp, and other materials between different processing machines.3. Steel mills: H78 Mill Chains are utilized in steel mills for moving heavy loads, such as steel coils, along conveyor systems. They are designed to withstand the demanding conditions and heavy loads present in steel manufacturing plants.4. Grain handling facilities: H78 Mill Chains are used in grain handling facilities, including grain elevators and silos. They are employed to transport grains, such as wheat, corn, and soybeans, through the different stages of processing and storage.5. Cement plants: H78 Mill Chains find application in cement manufacturing plants. They are used to transport raw materials, such as limestone and clay, to crushers, mills, and kilns, where they are processed into cement.7. Mining industry: H78 Mill Chains are utilized in mining operations for conveying heavy materials, including coal, ore, and minerals. They are used in various mining equipment, such as conveyor systems, bucket elevators, and crushers.8. Wood processing industry: H78 Mill Chains are used in wood processing facilities, including wood chippers, debarkers, and sawmills. They are employed for material handling, conveying logs, and transporting wood products. 

H78 Chain Sprockets and H78 Mill Chains

H78 Mill Chains are usually paired with compatible sprockets to create a reliable and efficient power transmission system. Sprockets are toothed wheels that engage with the chain, allowing for the transfer of power and motion. Here's some information about H78 chain sprockets and their compatibility with H78 Mill Chains:(1) Tooth Profile: H78 Mill Chains typically have a standard roller chain tooth profile. The teeth on the sprockets are designed to match the shape and pitch of the chain, ensuring proper engagement and smooth operation.(2) Pitch: The pitch refers to the distance between the centers of adjacent chain pins. H78 Mill Chains have a pitch of 2.609 inches (66.3 mm). Correspondingly, the H78 chain sprockets designed for H78 chains will have the same pitch to ensure proper alignment and engagement.(3) Number of Teeth: The number of teeth on the H78 chain sprockets can vary depending on the specific application and the desired speed ratio. Sprockets with more teeth provide higher speed reduction but may require a larger diameter. Conversely, sprockets with fewer teeth offer lower speed reduction but have a smaller diameter.(4) Material and Construction: H78 chain sprockets are typically made from durable materials such as steel or cast iron. These materials provide strength and resistance to wear, ensuring a long service life in demanding industrial environments.(5) Sprocket Hub: The hub of the H78 chain sprockets is the central portion that connects to the shaft. It is important to select sprockets with hub dimensions suitable for the specific application and shaft size.When selecting sprockets for H78 Mill Chains, it is crucial to ensure compatibility in terms of pitch, tooth profile, and number of teeth. It is recommended to consult with chain and sprocket manufacturers or suppliers to ensure the proper selection of sprockets that are specifically designed for H78 Mill Chains.
