Shot Blasting Machine

Description and Advantages of Shot Blasting Machine Wear Parts
The shot blasting machine constitutes the core component of shot blasting cleaning and strengthening equipment, with its operational efficiency and service life directly dependent upon the quality and compatibility of its wear parts.

Wear parts refer to components requiring periodic replacement due to impact, friction, and abrasion during the high-speed propulsion of steel shot (or other abrasives). Their types, characteristics, and advantages are crucial for controlling equipment maintenance costs and enhancing production efficiency.

Core Types and Description of Shot Blasting Machine Wear Parts The rate of wear for shot blasting machine components is closely related to the type of abrasive (steel shot, steel grit, steel wire cut shot), projection velocity, workpiece material, and processing volume.

No.	Item	Core function	Causes of wear
1	Blade	High-speed rotation propels the abrasive	The prolonged impact of abrasive particles on the impeller blade surfaces causes thinning, pitting, or notching of the blades. If the abrasive contains impurities (such as iron fragments or sand grains), this exacerbates localised wear.
2	Control cage	Controls the projection angle and range of the abrasive, ensuring precise targeting of the designated area	Abrasive particles continuously rub against the inner walls of the directional sleeve window during passage, causing window enlargement and edge blunting
3	Distributor	Distributes the abrasive from the feed inlet evenly between the impeller blades, preventing accumulation or uneven loading	Impact friction when abrasives enter the shot wheel, coupled with wear from interaction with impeller blades, results in shallower tooth grooves and inner wall abrasion on the shot wheel
4	Protect board	Protects non-wear components such as the shot blasting machine housing and bearings from direct abrasive impact	Rebounding abrasives repeatedly strike the surface of the protective plate, causing surface wear, pitting, or perforation

Core wear parts primarily include the following categories:

Core Advantages of Premium Shot Blasting Wear Parts
‘Longevity, Efficiency, Cost, Safety’
1. Exceptional Material Adaptability for Significantly Extended Service Life
Premium wear parts utilise customised materials tailored to specific operating conditions, reducing wear rates at source:
2. High precision ensures stable shot blasting efficiency and workpiece quality. The machining accuracy of wear parts directly impacts the stability of abrasive trajectory: – Premium impeller blades maintain dimensional tolerances within ±0.5mm, with post-installation coaxiality error ≤0.1mm. This guarantees uniform abrasive distribution, preventing localised ‘over-blasting’ or ‘under-blasting’ of workpieces.

3. Simplified installation reduces maintenance costs and downtime, further minimising equipment stoppages;

4. Enhanced safety mitigates operational risks; premium wear parts meet toughness standards, preventing sudden fracture even at maximum wear;
5.Consequently, superior wear components substantially boost operational efficiency and service life while significantly lowering user costs.
