    Once you know the ideal speed of rotation for your mill jars, you will need to design your mill around this critical parameter. With most ball mill designs, you have two areas of speed reduction to tweak: from the motor drive shaft to the drive pulley and from the roller bar to the milling jar.

  • Concrete steps towards profitability

    Ball mills are cylindrical steel shells with steel liners. These rotating drums contain grinding media that crash and tumble onto the raw material to grind down the particle size. Almost all ball mills use a form of closed circuit grinding that returns material that is too coarse back to the ball mill inlet while material fine enough to meet product requirements is sent to the product silo.
