Hook type shot blasting machine: the core tool for industrial surface treatment

1、 Working principle

Hook type shot blasting machine is a professional equipment that uses high-speed projectiles to impact the surface of workpieces, achieving cleaning, strengthening, and surface treatment. The core principle is based on:


The electric motor drives the shot blasting wheel to rotate at high speed, projecting metal pellets (such as steel pellets) onto the surface of the workpiece at a speed of 60-80 meters per second

Remove impurities such as oxide scale, rust, and welding slag through impact force, while enhancing surface hardness and fatigue resistance

The tiny dents formed by the impact of the projectile trigger plastic deformation and stress changes in the surface material, causing the brittle layer to peel off, forming a uniform roughness, and improving the adhesion of the coating

This process is efficient and stable, which can significantly extend the service life of the workpiece.

2、 Core structure

The hook type shot blasting machine is composed of multiple components working together, and its core structure includes:


Shot blasting cleaning room: steel plate welded structure, lined with high manganese steel protective plate, strong wear resistance, and a service life of up to 10 years

Shot blasting machine: Centrifugal shot blasting machine (such as QX130 type), with blades rotating at high speed to project pellets, supporting left and right rotation adjustment, and cleaning without dead corners

Bullet circulation system: elevator+separator+screw conveyor, automatic recycling and sorting, separation efficiency up to 99%

Hook system: Dual hooks alternate operation, supporting lifting, walking, and rotation, achieving 360 ° comprehensive cleaning

Dust removal system: Pulse back blowing technology, dust emission concentration lower than national standards, outstanding environmental protection

3、 Application Fields

With high efficiency and adaptability, it is widely used in:

Casting and forging: Removing casting sand and oxide scale to improve smoothness

Automobile manufacturing: Clean the frame and wheels to enhance fatigue resistance

Construction Machinery: Processing excavator and bulldozer structural components to extend equipment lifespan

Aerospace: Surface strengthening of aircraft components to ensure high-precision safety

Bridges and ships: Removing rust from steel structures and improving coating adhesion

4、 Core advantages

Efficient cleaning: High shot blasting design (such as QX130 type), achieving high-quality surface cleaning in a single treatment

No pit structure: saving infrastructure costs and avoiding pit water accumulation and corrosion in southern regions

Intelligent operation: The automation control system supports parameter preset and fault self diagnosis

Energy saving and environmental protection: high recycling rate of pellets, secondary dust removal in line with green production

Wide adaptability: capable of handling workpieces weighing tens of kilograms to several tons, suitable for slender/thin-walled vulnerable parts

5、 Maintenance and selection suggestions


Regular inspection: If the wear of the directional sleeve window exceeds 5mm, adjust the angle and replace it if it exceeds 15mm to avoid efficiency decline

Electrical maintenance: Keep the insulation resistance qualified and do not change the component model without authorization

Selection points: Select according to the size of the workpiece/double hook, heavy parts with electric hoist lifting system
