Working Principle of Ball mill As the mill rotates steel balls work to grind the materials The mill rotates approximately once every couple of seconds The grinding system uses either open circuit or closed circuit In an open circuit system the feed rate of materials is
Unused 5 diameter X 6 long Steel Lined Ball Mill manufactured by Patterson Industries Type D nonjacketed with AR400 steel liners Includes 30 HP 3 phase 60 Hz 230460 V 1725 RPM motor Mill drive is integrally coupled to horizontal parallel shafted helical gear reducer
With more than 100 years of experience in ball mill technology Metso Outotec ball mills are designed for long life and minimum maintenance They grind ores and other materials typically to 35 mesh or finer in a variety of applications both in open or closed circuits
Each milling circuit is unique and as such the goals and most optimal control strategy might differ for individual cases Process IQ is an expert in implementing control systems for SAG and Ball milling circuits making use of advanced stabilisation and optimisation strategies developed by Mintek
Developments in classification and mill speedup together with a finer ball mill feed size and substantial improvements to mill availability 99 in 1982 have further increased plant capacity There is a continuing emphasis on improving grinding circuit efficiency in terms of throughputgrind
