2. EQUIPMENT DESCRIPTION
The electrical dryer has been designed to operate outside or in a building above 40 deg. F. It is
designed to remove upto 10% of starting weight of moisture of 20,000 lbs hour material. A
moisture sensor located at the discharge will monitor the moisture content of the material leaving
the dryer and will adjust the amount of heat as required to maintain the desired discharge material
moisture levels.
Primary heater consists of 700KW heater unit with a 3,000 to 6,000 cfm fan that injects hot clean
air between temperatures of 200 f upto 700 f into the electric dryer.
Secondary heater consists of 150 kw heater unit with a 600 cfm fan that injects hot clean air
between 200 f upto 700 f into the electric dryer’s byproduct ducting to keep the air from not
concendating.
Baghouse is sized to capture all the byproduct material and have the moisture exist to
atmosphere.

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.

MAINTENANCE MANUAL – ELECTRIC ROTARY DRYER
FERREX ENGINEERING LTD. Page 6 Ref. #2278
Install the expansion joint between the vibrating inlet feeder and the drum inlet hood using
the clamps provided.
4. Fill the gearbox with oil to the oil fill level mark on the dip stick.
5. The air inlet assembly as shown on drawing 2243-4545-MC-123 will arrive in pieces to be
bolted together. The fan and the primary tube heater support frame would be anchored
(anchors by installer) to the building concrete floor after final assembly. Mount and bolt
the primary tube heater onto the tube heater support frame supplied. The un-insulated
tube heater inlet pipe will have the flanges tack welded only, for testing of the set-up,
which will allow a small amount of field adjustment, if required. Break the tack welds and
retack the flanges to the pipe if necessary to align bolts and ensure the pipe flanges are
flush. Use the garlock seals supplied for the 150# raised face flange connections to the
tube heater. After any field adjustments are completed then field weld the pipe flanges to
the pipe and bolt the inlet pipe to the fan and the primary tube heater. The primary tube
heater insulated discharge pipe would be bolted the drum inlet hood and the tube heater
discharge as shown. The flange connection to the primary tube heater would only be tack
welded to allow for a small amount of field adjustment as required. It may be required to
shim / move the tube heater and support frame if a large amount of adjustment is
required. The tube discharge pipe has an expansion joint located just after the
connection to the drum inlet hood. The discharge hood is supported with a bracket off the
inlet hood. Using the two bolts supplied, finger tightten (with jam nuts) the two bolts so
that the discharge pipe can float laterally relative to the expansion joint. After field
adjustment is complete, weld the 150# raised face flange to the discharge pipe and bolt to
the tube heater to the discharge pipe with the bolts supplied. Use the garlock seals
supplied for the 150# raised face flange connections to the tube heater. Use the small
container of paint supplied to repair paint and clean up any weld splatter. Install the pipe
insulation and insulation cladding.
6. The air discharge assembly as shown on drawing 2243-4545-MC-124 will arrive in pieces
to be bolted together. The secondary tube heater support frame is to be bolted to the
dryer drum frame as shown. The secondary heater fan support stool is then bolted to the
secondary tube heater support frame. On the opposite side of the drum, two brackets are

MAINTENANCE MANUAL – ELECTRIC ROTARY DRYER
FERREX ENGINEERING LTD. Page 7 Ref. #2278
to be bolted to the side of the dryer drum frame as shown used to support the insulated
baghouse inlet pipe. Mount and bolt the the secondary tube heater onto the support
frame. Mount and bolt the secondary fan to the fan support stool. Mount and bolt the
secondary tube heater inlet pipe between the fan and the secondary tube heater. Use the
garlock seals supplied for the 150# raised face flange connections to the tube heater.
The secondary tube heater insulated discharge pipe would be bolted at the top to the
insulated baghouse inlet pipe. At the top of the drum discharge hood the discharge
damper is to be bolted to the top of the drum discharge as shown. Bolt the insulated
discharge pipe to the secondary tube heater. Use the garlock seals supplied for the 150#
raised face flange connections to the tube heater. Use U-bolts to secure the insulated
baghouse inlet duct to the support brackets. Use the small container of paint supplied to
repair paint and clean up any weld splatter. Install the pipe insulation and insulation
cladding.

Seal assembly comes complete with the FabriSealtm, tension strapping and springs, and
strap length adjustment clips.

MAINTENANCE MANUAL – ELECTRIC ROTARY DRYER
FERREX ENGINEERING LTD. Page 8 Ref. #2278
Needed Tools:
1) Sockets and wrenches to fit nuts and bolts of mounting
assembly.
2) Sharp knife to cut bolt hole slits into seal.
FabriSealtm Installation:
1) Remove the old seal and replace any old bolts that are damaged.
2) Run a belt sander or grinder over the shell surface around the sealing area to remove any rust,
weld spatter, beads, or product buildup. If the shell walks longitudinally during operation, sand
the area also where the seal will ride. Polish the shell as much as possible as this will greatly
extend the effective life of the seal.
3) Lace the yellow tension straps through the belt loops. The straps should be laced in from the
ends of the seal to meet in the middle. There will be one segment for shell diameters up to 4’,
two segments for 4’-8’ diameters, and three segments for shells over 8’ OD.
4) Sling the seal over the shell such that the seal hangs evenly. This will allow the seal to overlap at
the exact bottom of the shell to facilitate possible feed dump cleanout.
5) Starting at the top, position the seal such that it forms a 90-degree angle with the shell (see
sketch pg. 3). The seal contact area should be about 2 ½” to 3”. Make sure there is not severe
seal sag between the ring and the shell (This will cause the seal to wander on the shell and
possibly invert back into the hood). Use a sharp knife and cut slits in from the outside edge of the
seal making sure to only cut deep enough to fit over the bolt holes. This will “relax” the seal on
the mounting ring as well as relieve the “pucker” on the shell surface.
6) Work your way down the sides fairly evenly cutting bolt hole slits. As sufficient bolt hole slits are
made, clamp the seal in place with the clamping ring segments.
7) When the bottom is reached, make sure the overlap corresponds with the direction of rotation
(see sketch pg. 3). If installed backwards, the seal will roll up and fail.
8) Lace the strap ends into the length adjustment clips. Affix the tension springs to the clips. Do not
attach the springs to anything other than the strapping clips and vice versa. Do not hang weights
from the springs or strapping. You can adjust the strapping length as needed.
9) Check the sag at the bottom of the seal. A slight gap (1/4” to ½”) is desirable at the bottom. This
will allow for thermal expansion of the shell when heated.
The last step is important such that testing is highly recommended prior to
operation.
10) Rotate the shell while pulling operating draft (if possible) to test the seal fit prior to firing and
operation. Observe the fit around the sealing surface. Adjust the fit accordingly remembering to
allow for thermal shell expansion. The seal only needs to make light continuous contact with the

MAINTENANCE MANUAL – ELECTRIC ROTARY DRYER

shell to be an effective seal. Cranking it down tight to the shell does NOT enhance the sealing
properties of the FabriSeal. All this will do is cause the seal to wear much faster.
