  • 4 Installation Steps, 10 Requirements and Medium

      Ball mill installation is a must step before it is put into production, which will affect the subsequent use of the ball mill, and even affect the production volume, crushing rate, service life, etc, so the importance of ball mill installation is selfevident In addition, the choice of grinding medium is also crucial In the grinding process, different grinding medium can be used for Figure 5 High–low wave ball mill liner Materials The selection of the material of construction is a function of the application, abrasivity of ore, size of mill, corrosion environment, size of balls, mill speed, etc liner design and material of construction are integral and cannot be chosen in isolationThe Selection and Design of Mill Liners MillTraj  circuits For this purpose, the case of Miduk copper mine in Kerman province, Iran was studied The samples were taken from primary ball mills feed and were subject to screen analysis to achieve uniform sizes Then, selection and breakage functions were determined at the different grinding times in laboratorial ball MINUTION MODELING OF PRIMARY BALL MILLS OF   Figure 3 shows the schematic diagram of one of the axial flowtype impact mills called a Super Micron Mill E This mill has a larger processing volume and operated at a middlerange speed but is capable of the finer grinding by the attrition mechanism and separation nozzle to discharge foreign materials, which often cause the reduction in the grinding capacity and the product qualityChapter 10 Selection of Fine Grinding Mills Ball Mill Design A survey of Australian processing plants revealed a maximum ball mill diameter of 524 meters and length of 884 meters (Morrell, 1996) Autogenous mills range up to 12 meters in diameter The lengthtodiameter ratios in the previous table are for normal applications For primary grinding, the ratio could vary between 1:1and AMIT 135: Lesson 7 Ball Mills Circuits – Mining Mill
