AG - Autogenous & SAG Semi-Autogenous Mill Design

17.04.2018· Mill Power required at pinionshaft = (240 x 16.5 x 1.025) ÷ 0.746 = 5440 Hp; Speed reducer efficiency: 98%; 5440 Hp ÷ 0.98 = 5550 HP (required minimum motor output power). Therefore select a mill to draw at least 5440 Hp at the pinionshaft. Based upon the pilot plant test results, the volumetric loading for the mill can be determined. Normally, autogenous and semi-autogenous millspower calculation formula of sag mill - harder-klassen.de,Mill (grinding) - Wikipedia. 2010109-formula known which connects the technical grinding work with grinding results.[8] A SAG mill with a 44' (13.4m) diameter and a power of 35 MW.GROSS POWER CALCULATOR - SMC Testing,calculations by the user. If the mill has cone ends the model automatically calculates the volume of the cone ends as well as the volume of balls/rock in the cone ends from the cylindrical section data that the user inputs. In SAG mills the total filling relates to the combined rock and ball volume (including voids),

Step-by-Step Sag and Tension Computation using

29.07.2018· A more accurate sag calculation of the sag can be done with numerical analysis. There are several computer programs that can do this, two of which are the Sagsec and PLS-CADD. These programs lets the user model the full line section and calculates, using finite element analysis, the forces on each insulator and the resulting sags of the line section can be determined. EXAMPLE CALCULATIONCalculation of Sag & Tension in Transmission Line - for,,Calculation of Sag and Tension at an unequal level supports. In hilly areas or sloping grounds, the supports are not usual at the same level. For the calculation of sag and tension at unequal supports level consider a conductor AOB. The portion of OA and OB may be treated as catenaries of half span x and l-x respectively shown in the figure,Sample Calculation of Sag and Tension of Transmission,13.01.2018· This is an example calculation for sag and tension in transmission line.
