    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.

  • Back to Basics Hammer Milling and Jet Milling Fundamentals

    A hammer mill is typically good for grinding softer materials with Mohs hard-ness ranging from 1 to 5 while a jet mill can grind materials with Mohs hardness as high as 10. High hardness materi-als become very abrasive therefore they are not suitable for high-speed hammer mills. In a typical jet mill grinding
