Product Introduction

Recommended Rod Mill Bar Length

Oct 01 2015 For rod mills larger than 38 meters 125 feet in diameter rod availability and quality have to be considered Table II gives rod length to mill diameter ratios for the larger diameter rod mills 68 meters 20 feet Is a practical limit on the length of good quality rods that is rods that will stay straight in the mill and will break in to

Mill Speed an overview ScienceDirect Topics

934 Mill Speed During normal operation the mill speed tends to vary with mill charge According to available literature the operating speeds of AG mills are much higher than conventional tumbling mills and are in the range of 8085 of the critical speed

In most cases the ideal mill speed will have the media tumbling from the top of the pile the shoulder to the bottom the toe with many impacts along the way The ideal mill speed is usually somewhere between 55 to 75 of critical speed Critical Mill Speed Critical Speed left is the speed at which the outer layer of media centrifuges against the wall Second Critical Speed middle is the speed at which

Rod mills have the highest rolling speeds with interpass times in the finishing stand of 15150 ms This is too short for either static recrystallization or straininduced precipitation and dynamic recrystallization is the main grain refining mechanism Microalloying could limit

Aug 28 2021 From the perspective of the development history of wire rod finishing mills the maximum rolling speed of ordinary rolling mills cannot be increased after increasing to 40ms Therefore the socalled highspeed rolling mill generally refers to a rolling mill with a maximum rolling speed higher than 40ms
