The feeding pipe (also known as the feeding tube) serves as the connection point between the pellet valve and the internal pellet wheels of the centrifugal hammer mill. It is responsible for precisely introducing the abrasive material into the center of the pellet wheels, and is subjected to the high-frequency scouring of the projectile flow. The feeding pipe is made of special high-chromium wear-resistant alloy, which can effectively solve the problem that ordinary steel pipes are prone to perforation and deformation under the impact of high-speed projectiles.
Core advantages and technical parameters
Outstanding high-chromium alloy material: Precisely cast using Cr12-Cr25 high-chromium cast iron, and after overall quenching treatment, the hardness can reach HRC58-62 degrees. This material not only resists wear but also has extremely strong impact toughness, with a service life that is 5-8 times longer than that of ordinary seamless steel pipes.
Low-resistance inner wall design: The inner wall of the pipe cavity has been smoothed, resulting in an extremely low friction coefficient. This ensures smooth flow of steel balls when they enter the centrifugal hammer, completely eliminating the problems of "sticking balls" and "blocking balls", making the supply of balls more stable and improving the efficiency of the centrifugal hammer impact.
Precise flanges and seals: The input and output ends are precisely machined by CNC to ensure a tight fit with the ball supply system and the centrifugal hammer housing. The excellent sealing performance effectively prevents the leakage of steel balls, keeps the working environment clean and reduces safety hazards.
Multi-brand specifications compatibility: Supports 1:1 precise substitution for international brand models.
