A Little Wisdom Helps You Become Smarter !In the video, workers forge grinding balls for cement mills. Using long tongs, a worker grips a red-hot steel billet (non-spherical) and positions it under an air hammer. Through repeated forging while constantly rotating the billet, it gradually transforms into a perfect sphere. The shaped ball then rolls through a V-shaped metal chute into a spiral cooling ramp before being quenched in a liquid tank to achieve maximum hardness.
