Also the grinding efficiency of ball mill will reduce. If the steel balls are too small, even the collision probability is relatively high, but the energy of single steel ball is very small, which cannot efficiently grind the ore particles, also leading to the reduction of grinding efficiency.Get A Quote

This is particularly true for some of the secondary grinding primary ball mills of magnetic iron ores. In magnetic iron ore grinding, the silica levels are continually being decreased from crushing to rod milling to ball milling by intermediate concentration steps. Subsequently, the wear environment becomes progressively less abrasive.

The ore is conveyed, and lime is added 2 to raise the pH of the ore. Following crushing through a jaw crusher 3, the ore is fed into the semi autogenous grinding SAG mill 4 along with water and steel balls. The grinding process reduces the rock to a slurry. The SAG mill is a large revolving cylinder.
energy required which in this case was to grind the ore represented by the samples, from a feed size F80 of 152 mm to 80 passing 1.7 mm, and a simple adjustment procedure in case the SAG product size needed to be adjusted. Bond rod and ball mill work indices are readily converted to pinion energy for rod and ball mills but not for SAG mills.
