Papermaking PAPERMACHINE – DRYING Introduction

Paper machine dryers have been modelled using computers and rigorous application of heat and mass transfer principles. However, there is often a need for some simple estimates of dryer sections of paper machines. In this case, data compiled from industry averages are frequently used. The TAPPI drying rates shown in Figure 14 are one source.

Gear Train : Gear Ratio, Torque and Speed Calculations ...

Gear ratio is the ratio of the number of teeth of driven gear and driver gear. It is used to calculate the speed and torque of output shaft when input and output shafts are connected using a gear train. Input gear where torque is applied is known as driver. Whereas output gear is known as driven gear.
