Applications of Shot Peening in Wind Power and New Energy:
1. Gearboxes and bearings: Shot peening brings residual compressive stress into gear tooth surfaces, greatly improving their fatigue resistance and wear resistance. Precision strengthening techniques such as fine-particle peening are an effective way to extend bearing service life and improve operational safety.
2. Steel plate pre-treatment: Thick plates for wind tower barrels are pre-treated on a roller-conveyor blaster before rolling. This can thoroughly remove surface oxide scale and corrosion and create a controlled surface roughness that enhances the adhesion of subsequent coatings.
3. Wind turbine blades: Blades are the core components for capturing wind energy and are continuously subjected to vibrational stress, making fatigue their primary failure mode. Shot peening is currently the most economical and effective solution to metal fatigue in blades. During blade manufacturing, blasting is also used to clean surface contaminants and oxide scale and to improve surface quality.

We Understand Your Supply Requirements:
1. Mass stable supply capability: Wind power components feature large dimensions—tower diameters can range from Φ2,500 to Φ8,100 mm, lengths reach 36,000 mm, and individual pieces weigh up to 160 tonnes. Wind turbine gears can reach 800 mm in diameter with a hardness of 60 HRC. Media consumption is enormous, requiring suppliers to maintain large-scale, continuous, and dependable delivery capability.
2. Precise shot size control: Precision components such as wind turbine gears require tightly controlled shot sizes (e.g., 0.8 mm). Variations in particle size can directly affect peening performance and surface finish, so suppliers must have precise screening and classification capabilities.
3. Product consistency and traceability: Wind power equipment demands exceptional reliability, making batch-to-batch consistency in shot media hardness, particle size, and chemical composition essential. A comprehensive quality traceability system is therefore required.
4. End-to-end technical service: Suppliers must be able to provide blasting/peening process solutions tailored to different components—gears, towers, hubs, and others—and must have professional testing capability for residual stress, roughness, and similar parameters.
5. Strict compliance with international and national standards: Wind power equipment is exposed year-round to harsh onshore and offshore environments while it is designed for a service life of more than 20 years, so the quality of surface treatment can directly determine service life.
