60 70 80 mm Forged grinding steel ball and steel iron balls for ball mill

Short Description:

Our company producing high quality grinding steel balls (dia. from 15mm up to 130 mm ), is the leading grinding media producer and exporter company in China. The reason for the production of balls of various diameters; in the spherical shaped balls, there is a large gap between the balls in a fixed volume filled with the same diameter. In this respect, instead of the mill charge consisting of the same diameter ball, it is ensured that the balls are minimized by using a charge of different diameter balls and the balls are doing the best job.
