What is ball milling A ball mill is a type of grinder used to grind materials into extremely fine powder 7 Major parameters for ball milling Temperature Size and Number of the balls Nature of the balls Rotation speed 8 Types of Ball Mills
A ball mill also known as pebble mill or tumbling mill is a milling machine that consists of a hallow cylinder containing balls mounted on a metallic frame such that it can be rotated along its longitudinal axis The balls which could be of different diameter occupy 30 50 of the mill volume and its size depends on the feed and mill size
Closed circuit ball mill – Basics revisited
Mill Type Overview Three types of mill design are common The Overflow Discharge mill is best suited for fine grinding to 75 – 106 microns The Diaphram or Grate Discharge mill keeps coarse particles within the mill for additional grinding and typically used for grinds to 150 – 250 microns The CenterPeriphery Discharge mill has feed reporting from both ends and the product discharges
