BALL MILLS AND GRINDING MEDIA

Steel balls used in grinding medium are used in grinding of ore to fine dimensions in ball mills.Mill balls are used in semi-autogenous and ball mills. Semi-autogenous grinding; is a type of grinding carried out with a small amount of ball charge and with the help of bigger parts crumbling the smaller parts of ore.

Our company producing high quality grinding steel balls (dia. from 20 mm up to 125 mm ), is the leading grinding media producer and exporter company in Turkey. 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.

SAG MILLS (SEMI AUTOGENOUS GRINDING)

SAG mills (semi-autogenous milling) is a type of grinding carried out with a small amount of ball charge and with the help of bigger parts crumbling the smaller parts of ore. In addition to being preferred in gold, copper, platinum and silver mines, SAG MILLS are preferred in mines such as lead, zinc, alumina and nickel.

The SAG mills are usually primary or first stage mills.
The SAG mills are characterized by large diameters and short lengths compared to ball mills.

Advantages And Features Of SAG Mills ;

  • Crushing, grinding and washing are made together, the machines with the highest reduction rate. It offers a much smaller reduction ratio than the size reduction done by the three-stage crushing and screening process.
  • Wet and dry grinding.
  • High capacity.
  • They have the ability to grind materials up to 400 mm to 75 microns.
  • In the grinding mills, between 8% and 21% of the ball charge is used.
  • Grinding media is grinding ball diameter 100-125 mm mills.
