Conical Ball Mills differ in mill body construction, which is composed of two cones and a short cylindrical part located between them (Fig 212)Such a ball mill body is expedient because efficiency is appreciably increased Peripheral velocity along the conical drum scales down in the direction from the cylindrical part to the discharge outlet; the helix angle of balls is decreasedATTRITORS AND BALL MILLS HOW THEY WORK Robert E the mill The common range of mill speeds is 65 to 80 of critical depending on mill type size and the application The critical speed of a ball mill is calculated as 5419 divided by the square root of the radius in feet The rotational speed is defined as a percentage of the critical speed Smallerwhat is critical speed in a ball mill
