In the realm of environmental and water treatment, where demanding applications require robust and reliable equipment, combination chains stand out as essential components. These chains, specifically designed for conveyor systems, play a crucial role in moving, transporting, and processing materials crucial for cleaning and purifying our environment.
Understanding the Structure:
Combination chains, as the name suggests, are a combination of different elements that work together to form a strong and durable chain. The most common type features cast block links made from high-strength materials like steel or iron. These blocks are connected by steel pins, which serve as the chain's pivoting points, and connecting bars, which provide structural rigidity.
