Spinner-Hanger Shot Blasting Machine

Spinner-Hanger Shot Blasting Machine: Precision Surface Treatment for Complex Components
In industries requiring thorough surface cleaning, deburring, or preparation of heavy or irregularly shaped parts, ‌Spinner-Hanger Shot Blasting Machines‌ offer a specialized solution. Combining rotational motion with high-velocity abrasive projection, this equipment ensures uniform treatment of complex geometries while maintaining efficiency and reliability.

The Spinner hanger shot blasting machine consists of units featuring single hook, double hook, lifting and non-lifting style designed to blast/peen castings, structural components, non-ferrous alloy parts.

Overview of Spinner-Hanger Shot Blasting Technology
A Spinner-Hanger Shot Blasting Machine is designed to process components suspended on hooks or fixtures that rotate continuously during blasting. This dual-axis movement (rotation of the hanger and spinning of the workpiece) ensures all surfaces, including internal cavities and recesses, are exposed to abrasive media.

Applications

Spinner-Hanger machines excel in industries requiring precision and versatility:

‌Automotive‌: Cleaning engine blocks, gears, and transmission components.
‌Aerospace‌: Surface preparation for turbine blades and structural castings.
‌Foundries‌: Removing sand and slag from large castings or forgings.
‌Railway‌: De-scaling wheels, axles, and couplers.
‌Energy‌: Treating wind turbine components or pipeline fittings.

Key Components
‌Rotating Hanger System‌:

Motor-driven hooks or fixtures hold workpieces and spin them at adjustable speeds (typically 3–10 RPM).
Compatible with single or multiple parts, depending on size and weight capacity.
‌Blasting Chamber‌:

Reinforced steel enclosure lined with replaceable wear-resistant manganese steel or polyurethane liners.
Equipped with high-efficiency centrifugal turbine wheels (impellers) to propel abrasive media at speeds up to 80 m/s.
‌Abrasive Recycling System‌:

Separates reusable abrasives (e.g., steel shot, grit, or cut wire) from contaminants like dust or broken particles.
Includes elevators, vibrating screens, and airwash separators for continuous operation.
‌Dust Collector‌:

Industrial-grade cyclone or cartridge filters capture airborne particulates, ensuring compliance with OSHA and EPA standards.
‌Control Panel‌:

Programmable Logic Controller (PLC) automates rotational speed, blast time, and abrasive flow for repeatable results.
