3. ASSEMBLY / SET-UP
The dryer drum assembly was assembled and dry tested at the fabricating shop prior to shipping.
The dryer drum assembly will be shipped assembled. The remaining air inlet assembly and the
air discharge assembly will be broken down with flanged bolted connections required to comply
with shipping regulations. The bearings will be lubricated at assembly. When the unit arrives, it
should be carefully inspected to make sure that the unit is in good condition and that all of the
components listed on the packing slip are received. Loose items are typically packed in boxes on
a skid.
The field flanged assembled duct / pipe components will require dust tight sealed connections.
Use high temperature joint strip gasket material with joint sealing compound to the housing
flanges. When possible, gasketing should be done on the ground before hoisting the piece into
place. Duct / pipe sections after the primary and secondary tube heaters are to be insulated. The
insulation and the insulation metal coverings including the duct elbows will be supplied and
installed during installation. The pipe insulation comes in split preformed sections for easy
installation including the tape to seal the insulation joint. The rolled metal insulation cover is to be
cut and strapped to the outside of the insulation. Suitable caulking to seal the metal cladding and
boots for the ends are supplied.
1. The dryer drum assembly will require a spreader beam and straps to be crane lifted off
the shipping truck and again during installation. Crane should be rate 20 tons capacity.
2. Using a spreader beam and straps lift and mount the dryer drum assembly on to the drum
support frame (drum support frame by installer). Using shims, level the dryer drum and
bolt (bolts by installer) the drum to the support frame at six column locations. The dryer
drum is to be at an 1.25 degree angle of incline.
3. Mount the vibrating inlet feeder on to the feeder support frame (feeder support frame by
installer). The feeder discharge tube is to be aligned with the inlet hole on the face of the
drum inlet hood. Using shims as required, bolt the vibrating feeder to the support frame.
