The impeller is the core component of the centrifugal hammerer that controls the direction of the projectile projection and the initial momentum. It is installed inside the directional sleeve and rotates at high speed synchronously with the main shaft. Its main function is to pre-accelerate the scattered steel balls from the feeding pipe and evenly and precisely distribute them to each blade through the window, serving as the "road sign" that determines the efficiency and projection accuracy of the shot blasting.

Core technical advantages

Ultra-high wear-resistant alloy material: Precisely cast using high-chromium wear-resistant cast iron (Cr15-Cr28), with a hardness of up to 60-65 HRC. It has excellent anti-corrosion performance and can maintain the inner wall shape even under high-speed and dense steel ball impacts, reducing wear.

Scientific fender structure design: The internal flow channels have been optimized by fluid mechanics to ensure that the steel balls do not accumulate or get blocked during distribution. Through precise control of the blade slot spacing, the projectiles are uniformly and progressively delivered, effectively avoiding the uneven force on the blades and the resulting uneven wear.

Dynamic balance and high adaptability: Each impeller undergoes dynamic balance testing to ensure it runs concentrically with the drive disc and the center disc. The specifications cover a full range of shot blasting machine models, are installed tightly, and the transmission is reliable.

Improving the projection quality: High-quality impeller ensure a more concentrated projection, significantly improving the cleaning efficiency of the workpiece surface, shortening the shot blasting cycle, and reducing the loss of abrasive materials.
