Is Specifon For Ball Mill 50 Mw

  • Amit 135 Lesson 7 Ball Mills Amp Circuits Mining Mill

    For overflow ball mills, the charge should not exceed 45 of the mill volume . For grate discharge mills, the charge should occupy about 50 of the mill volume . Bond developed a relationship that can be used to determine the percent charge by volume as a function of the vertical height above the charge, He, and the radius of the mill, R, i.e.,For overflow ball mills, the charge should not exceed 45 of the mill volume . For grate discharge mills, the charge should occupy about 50 of the mill volume . Bond developed a relationship that can be used to determine the percent charge by volume as a function of the vertical height above the charge, He, and the radius of the mill, R, i.e.,Between 2001 and 2008, a limit of 22 MW was placed on SAG mill drives as GMDs by some operators and principal motor designersmanufacturers until the reasons for known problems in design or manufacturing were better understood and resolved. Accordingly, the latest 40 ft dia. SAG mill is rated at 29 MW and 78 C.S., with a 42 ft dia.Figure 4 Two SAG Mills 24MW each and Two Ball Mills 16.4 MW each with Gearless Mill Drives For larger applications the well-proven Gearless Mill Drive GMD technology has shown to be very effective since its introduction in mining in 1980 currently in operation for horizontal mills up to 40 feet 12.2m diameter with power ratings up to 28 ...Dec 18, 2013 This quantity is small compared to the power used by a semi-autogenous mill and a ball mill in a primary grinding circuit a ball mill can have an installed power of up to 15 MW, while installed power for a SAG mill can go up to 25 MW. However, the energy used for fine grinding is still significant.
