What is Suspension Type Shot Blast Machine? 

A Suspension Type Shot Blast Machine is a type of surface treatment equipment that uses a suspended chain or hook system to transport workpieces through a shot blasting chamber. Here are the key characteristics and applications of this machine:

Definition

A Suspension Type Shot Blast Machine is designed to clean, de-rust, de-scale, and strengthen the surface of various metal parts by propelling abrasive media (such as steel shot or grit) at high speed onto the workpiece surface.

Components

l Blast Wheel: The core component that propels the abrasive media.

l Shot Blasting Chamber: The enclosed area where the blasting process takes place.

l Screw Conveyor and Elevator: Used to recycle and transport the abrasive media.

l Separator: Separates usable abrasive from dust and debris.

l Dust Collector: Removes dust and particulates from the air.

l Hook or Chain System: Suspends and transports the workpieces through the machine.

Applications

l Surface Cleaning: Removes rust, scale, and welding slag from steel structures, castings, and forgings.

l Surface Strengthening: Increases the fatigue strength of mechanical parts such as springs and gears through shot peening.

l Surface Preparation: Prepares surfaces for coating or painting by creating a uniform metallic luster.

Advantages

l High Efficiency: Continuous or step-by-step operation allows for high productivity.

l Versatility: Suitable for a wide range of workpiece sizes and types.

l Automated Operation: Reduces manual labor and improves consistency.

Technical Parameters

l Carrying Capacity: Single hooks can carry from 50 to 2000 kg.

l Cleaning Size: Varies depending on the model, with dimensions ranging from 500×1200 mm to 700×2400 mm.

l Power Consumption: Typically ranges from 38.75 kW to 122.6 kW.

Types

l Continuous Type: Workpieces move continuously through the machine.

l Step-by-Step Type: Workpieces move in steps, allowing for more precise control.

l Accumulating Roller Conveyor Type: Combines the benefits of continuous and step-by-step operations.

Suspension Type Shot Blast Machines are widely used in industries such as automotive, aerospace, shipbuilding, and general manufacturing for improving the quality and durability of metal components.
