Critical speed depends upon the magnitude and location of the shaft unbalance the length of the shaft its diameter and the kind of bearing support Many practical applications suggest as good practice that the maximum operating speed should not exceed 75% of the critical speed however there are cases that require speeds above the critical speed to work correctly In such cases it is

the feed percentage of intermediate size particles M Silva A Casali the SAG mill critical speed Pc = SAG mill power consumption (kW) % 600 +100 = % of the fresh feed in the size range 152 +25 mm M Silva A Casali/Minerals Engineering 70 (2015) 156–161 157 In fact the later can be modelled as a function of the others Addi-tionally as has been shown by Powell et al (2001) ball

The milling process – definitions Cutting speed v c Indicates the surface speed at which the cutting edge machines the workpiece Effective or true cutting speed v e Indicates the surface speed at the effective diameter (DC ap) This value is necessary for determining the true cutting data at the actual depth of cut (a p) This is a particularly important value when using round insert cutters

LOCKED CHARGE STARTS AND YOUR GRINDING MILL Authors Jeff Belke Mitch Bertrand Damaged radial bearing Output SEAP September 2012 / 2 CAUSES SAG and ball mills with grate discharge are not prone to locked charge events because of the high amount of rocks and balls compared to fine ore The pulp dischargers of a SAG mill continually pump the finer material out of the mill

Base calculations for cutting speed based on true or Ball nose cutter Round insert cutter Point milling – tilted cutter When using a ball nose end mill the most critical area of the cutting edge is the tool center where the cutting speed is close to zero which is unfavorable for the cutting process Chip evacuation at the tool center is critical due to the narrow space at the chisel

Critical speed used in this context is a term for the speed at which a vehicle will lose lateral control on a given roadway curve The normally flawed procedure is to assume the highway curve radius as the critical path taken by the vehicle On the surface this procedure appears reasonable since the driver is apparently attempting to drive around the roadway curve This theory fails however
