Hansheng Automation (Dongguan) Co., Ltd.

Hansheng Automation provides high-precision, wear-resistant bucket elevator sprockets. Typically used with various conveyor roller chains and round link chains, our products are widely utilized in vertical conveying systems across cement, mining, power generation, port, and grain industries. We support custom manufacturing based on your drawings or samples, with comprehensive quality control throughout the entire process.

[Core Features & Advantages]

High Machining Precision: Critical areas of our sprockets, including the inner bore, keyway, and mating surfaces, feature high machining precision (down to within ±0.005 mm). This helps ensure good concentricity between the sprocket and the drive shaft, reducing vibration during operation and extending the service life of reducers, bearings, and chains.
Excellent Wear & Impact Resistance (Hard Surface with Tough Core): Depending on your operating conditions, we utilize materials such as high-strength wear-resistant alloy steel or high-manganese steel. Combined with controlled tooth induction hardening processes, the tooth surface hardness reaches HRC 55–62, balancing high wear resistance with impact toughness.
Extensive Customization Experience: Whether you require standard-sized drive sprockets, tail sprockets, or split (segmented) sprockets designed for easy maintenance in elevated or confined spaces, we can manufacture them based on your drawings or samples to meet your equipment's installation and operational requirements.

[Our Manufacturing & Quality Control Process]

Technical Discussion & Design: Our engineers communicate with you to understand your equipment model, conveyed materials, and working conditions, recommending the most suitable material and structural design.
Precision Casting: We utilize lost foam or sand casting processes combined with high-precision molds to ensure a dense internal structure and mechanical properties for the sprocket blanks.
CNC Precision Machining: Utilizing large horizontal machining centers and other advanced equipment, we perform precise machining on the sprocket teeth, inner bores, and faces to ensure all critical dimensions match your drawings.
Controlled Heat Treatment: We apply induction hardening or overall tempering to the sprocket teeth, providing appropriate surface wear resistance and structural fatigue strength.
Strict Quality Inspection: Finished products are inspected using coordinate measuring machines (CMM) and other testing equipment for dimensional and geometric tolerances, ensuring delivered products comply with technical specifications.

[Typical Application Fields]

Building Materials: Cement plants, concrete batching plants (for vertical conveying of clinker, limestone, sand, etc.)
Mining Industry: Metal and non-metal mines (for lifting ores, concentrates, etc.)
Power Industry: Coal-fired power plants (for conveying coal, fly ash, etc.)
Ports & Terminals: Bulk terminals (for loading and unloading grain, ores, fertilizers, etc.)
Chemical Industry: Fertilizer plants, chemical manufacturing facilities (for conveying various chemical raw materials)
Grain Industry: Silos, feed processing plants (for vertical lifting of grains, pellet feeds, etc.)

[FAQ]

Q: How does the price of your sprockets compare to standard market options?
A: Our pricing is based on your specific specifications and manufacturing requirements. While the initial procurement cost may vary, our sprockets offer an extended service life and reduce wear on adjacent drive components. This significantly lowers downtime and replacement frequency, making them a cost-effective choice in terms of Total Cost of Ownership (TCO).

Q: What is the strength and reliability of split sprockets?
A: Through optimized structural design and high-strength connecting bolts, our split sprockets achieve strength and rigidity comparable to integral sprockets. Their primary advantage lies in simplifying installation and replacement in elevated or confined spaces, which significantly reduces maintenance time.

Q: What is the typical lead time from order to delivery?
A: The lead time depends on the sprocket specifications, structural complexity, and our current production schedule. Generally, the production cycle for standard products is about 15 working days. We will provide a more precise lead time upon receiving your specific inquiry.
