Grinding Ball Forged Steel Balls
Product Description
Introduction of the Forged steel balls
Junda forged steel ball is tight inside, made of round steel forging, avoiding the defects caused by the process in the cast state, the internal density is large, the fine particle size is high, the ball's drop resistance and impact toughness are enhanced, thus reducing the crushing rate of the ball; The impact toughness is 4-5 times that of the cast ball, and this technical parameter determines that the crushing rate of the forged ball is much lower than that of the cast ball
