In Grinding, selecting (calculate) the correct or optimum ball size that allows for the best and optimum/ideal or target grind size to be achieved by your ball mill is an important thing for a Mineral Processing Engineer AKA Metallurgist to do Often, theMill 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 dischargesAMIT 135: Lesson 7 Ball Mills & Circuits – Mining Mill
operating parameters Mill speed, mill charge, ball size, and wet grinding are the parameters which have been selected for the present study It is hoped that the analysis of the data acquired will allow insight as to which parameters will require a functional form if they were to be integrated into a complete liberation model · 12Balls either cascade or tumble during processing in these mills depending on rotational speed (see Fig 3) The time taken to achieve MA scales approximately inversely to the size of the milling equipment used Hence, milling which might take minutes to accomplish in a SPEX mill could take hours in an attritor or days in a horizontal ball millHighEnergy Ball Milling an overview | ScienceDirect Topics
