rotary dryer girth gear root clearance

Oct 01, 2016 Fig. 1 is a schematic diagram and photograph of the girth gear of a rotary dryer in a chemical plant. The gear was fabricated from low alloy cast steel. Due to its inclination (1 18') and a lifter flights system, the dryer operating at 2.5 rpm makes the product drive along its inside mixing it with hot gases about 130 C.In this way, the material gets dry slowly and the gases

Since the root clearance in the cold condition is already too tight why take any risk? Re-adjust the rollers now to set the required back-lash and root clearance at the tightest spot to the minimum or even a little
