Specialized Spare Parts for Through-Type Shot Blasting Machines

The operating reliability of the entire machine depends primarily on the roller conveyor system and the inlet/outlet sealing system. Under high-temperature and high-humidity conditions in some countries and regions, three common failures are frequently seen: aging and cracking of roller sleeves, corrosion and elongation of conveyor chains, and wear-through at the bottom of inlet/outlet sealing curtains. These issues can easily lead to steel shot leakage, excessive workshop dust, and increased abrasive consumption.

Direct Shipping from the Nearest Warehouse: A full range of spare parts, including conveyor rollers, roller sleeves, conveyor chains/sprockets, inlet and outlet sealing curtains, cleaning brushes, and blow-off devices, are kept in stock at our domestic and overseas warehouses. Standard models can be shipped directly from the nearest warehouse within 3–5 days. Custom roller conveyor systems with non-standard roller spacing or roller diameters can also be manufactured according to drawings.

Material Selection & Wear Resistance: The roller body is made from seamless steel pipe or welded steel structure with quenching and tempering treatment. Roller sleeves are available in high-chromium cast iron, polyurethane-coated, or wear-resistant rubber versions. High-chromium sleeves offer longer service life but generate more operating noise; polyurethane-coated sleeves are well suited for thin plates and help prevent impact damage; rubber sleeves are more cost-effective but generally require more frequent replacement.

The sealing curtains use a multi-layer wear-resistant rubber sheet structure, allowing individual layers to be replaced separately to reduce maintenance costs. Blow-off air knives are made from aluminum alloy or stainless steel and feature an adjustable blowing angle.
