are the balls ball mills made for the grinding iron ore

Rexor and Company, INC.

Grinding Media (Balls & Rods) Grinding media, made from carbon steel infused with various chemical elements to impart excellent hardness properties, are the means to grind material inside mills (i.e. Ball & SAG mills). In the mining industry, the grinding media used are commonly in the form of balls but sometimes take the shape of rods as well.

Ball Mill - an overview | ScienceDirect Topics

Ball mills give a controlled final grind and produce flotation feed of a uniform size. Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.-% ore and 25% steel.
