    Recommended Ball Mill Speed & Liner Configuration

    Oct 25, 2017 Oct 25, 2017 Mill critical speed is defined as that rotational speed at which an infinitely small particle will centrifuge, assuming no slippage between the particle and the shell. The critical speed, Nc, in revolutions per minute, is a function of the mill diameter, D, expressed as: Nc = 42.3/√D (meters) or Nc = 76.63/√D (feet)

    Choose right speed to improve ball mill grinding

    Ball mills generally work in a “dropped” state. There are many working speeds to achieve this working state, but there must be the most favorable working speed. In order for the ball mill to perform normal grinding operations, its working speed must be less than the critical speed. Ball mills generally work in

    Mill Speed - Critical Speed. Mill Speed . No matter how large or small a mill, ball mill, ceramic lined mill, pebble mill, jar mill or laboratory jar rolling mill, its rotational speed is important to proper and efficient mill operation. Too low a speed and little energy is imparted on the product

    Variables in Ball Mill Operation | Paul O. Abbe®

    In ball milling of dry solids the main independent variables are mill diameter, mill speed, media size, solids loading and residence time. For most companies the production mill already exists so we can ignore mill diameter and focus on the other variables. Mill Speed is one variable that can often be easily changed with a variable frequency
