MEETING OF APRIL 2, 2024
TO: Mayor Jordan and City Council
CITY COUNCIL MEMO
THRU: Susan Norton, Chief of Staff
FROM: Tim Nyander, Utilities Director
SUBJECT: Griffin Residuals — Amendment No. 1 to Drying as a Service Agreement
RECOMMENDATION:
2024-1827
Staff recommends approval of Amendment No. 1 to the Drying as a Service Agreement with Griffin Residuals,
LLC in the total amount of $91,668.69 including taxes and freight charges for the purchase of a hopper and
conveyor for the thermal dryer at the Biosolids Management Site.
BACKGROUND:
The City of Fayetteville, Jacobs Engineering, and Griffin Residuals have been working this past year to install a
biosolids dryer to replace the one that experienced catastrophic failure on December 13, 2021. A main issue is
the method used to feed the solids from the solar houses to the dryer.
DISCUSSION:
In order to conserve funds, the City attempted to use a portion of the existing conveying equipment when
installing the new dryer. This included the original feed hopper and chain -drive conveyor systems. The issue
was that the old dryer was a batch operation and the new dryer is a continuous feed operation. It was not
working well, and after many attempts is was decided that a hopper of a different design as well as a belt -type
auger was needed to successfully transfer the solids to the dryer.
It was not logical for the City to pay for equipment until we were sure it would be effective, but we didn't know if
it would work until it was installed. Therefore, Griffin Residuals purchased the equipment in advance knowing it
would become City property if successful. Now that it is installed and working, the City can take ownership of
the equipment. The conveying equipment is not part of the Drying as a Service Agreement, and the equipment
will be a City asset.
BUDGET/STAFF IMPACT:
Budgeted funds for this purchase will be utilized from the WWTP Building Improvement project.

Safety Bolts
Safety is a primary concern for all employers, especially in manufacturing facilities.
Bulk material handling equipment with rotating components present risk of injury to
workers. Every person working in a manufacturing environment must be trained in
safe practices by their employer. Even with safety training, there is still a chance for
an accident to occur. KWS provides solutions to minimize risk of injury with the use
of safety bolts for conveyor covers.
With over 45 years'experience in the bulk material handling industry, KWS is at the
forefront of safe equipment design. KWS safety bolts satisfy the requirements of both
OSHA and MSHA (Mine Safety & Health Administration). While standard cover bolts
require a tool to remove, KWS safety bolts require a specific tool for access by only
trained maintenance personnel.
Features
Variety of Construction Materials: KWS safety bolts are provided in either zinc
plated carbon steel or 18-8 stainless steel.
Universal Implementation: Screw clamps are a common method of fixing a
conveyor cover in place but allow for the cover to be easily removed. KWS provides
safety bolts even on assembled conveyors utilizing screw clamps.
Benefits
Efficient Installation: Two KWS safety bolts are installed on every cover in opposite
corners to prevent access to moving components. Locating the safety bolts on
opposite corners maximizes the safety benefit without delaying access to the equip-
ment by trained maintenance personnel.
Safe Operation: KWS safety bolts require a specific tool for removal, restricting
access to only trained maintenance personnel. KWS ships the special tools with each
assembled conveyor, enclosed in a packet with additional safety and operation
information.

Straightening the Screw
Minimal screw deflection and shaft run -out are keys to successful long-term screw
conveyor operation. A bent screw can lead to excessive flight wear or damage,
excessive shaft run -out and failure of seals, bearings, and drive components.
After welding the flights to the center pipe, screws must be routed back to the shop
for straightening. Heat from the welding process introduces stresses and can distort
the screw. KWS checks and straightens each screw section to exacting standards.
Features
Dial Indicators - Dial indicators are used to measure the run -out in the
bearing area of the shaft.
Total Run -Out - Run -out is a measurement of shaft movement. KWS
straightens each screw for a maximum run -out of 0.015-inch T.I.R.
at the bearing area.
Process - A combination of heat and mechanical leverage is used to
straighten the screw.
Benefits
Extended Life - Having a straight screw will extend the life of the screw by
removing excess deflection that can cause extra wear on the flights. Having a
straight screw will extend the life of bearings, seals and drive components.
Reduced Stress - Having a straight screw will put less stress on the pipe and shafts
reducing potential fatigue fractures and breaks, as well as reducing stress on the
bearings, seals, and drive components.
Reduced Vibration - For high-speed applications, the straightening process
minimizes screw deflection. The result is smoother running, less vibration, and
longer component life.

Bulkhead Trough Ends
Bulkhead trough ends are trough ends that include a removable mounting plate for
the drive or bearing. Bulkhead trough ends give greater range and versatility in the
selection of seals, bearings, and drives over standard trough ends. They are used for
more demanding applications.
By providing space between the trough end and the drive mounting plate, bulkhead
trough ends help prevent contamination of the drive or bearing. This space also
helps protect the drive or bearing from heat when conveying high temperature
products.
Features
Unique Design - Our unique design utilizes a trough end with a welded standoff
and removable mounting plate that provides complete rigidity and ensures no drive
movement.
Wide Variety of Construction Materials - Bulkhead trough ends can be
000 constructed out of carbon steel, stainless steel, or high -nickel alloys for corrosion
resistance or high temperature applications.
Wide Variety of Seal Options - Bulkhead trough ends are designed to accept
flanged gland seals with multiple rings of packing, split gland packing seals with a
single ring of packing, waste pack seals, air or nitrogen purged seals, food grade
seals, mechanical seals, or even custom designed seals.
Wide Variety of Drive and Bearing Options - Bulkhead trough ends are designed
to accept seals, drives and bearing units from nearly all manufacturers.
Benefits
Protect Drives and Bearings from Heat and Contamination - The bulkhead
design moves the drive or bearing away from the trough end and potential contami-
nation or damage from either abrasive or corrosive products or products conveyed
at elevated temperatures.
Used in Wide Variety of Applications - Because of the variety of construction
Design materials, pedestal trough ends can be used in everything from food grade to heavy
Engineering industrial grade applications.

Feeder Shrouds
Screw feeders are used in thousands of material handling applications and designed
to meter bulk materials at a controlled feed rate. The inlet of a screw feeder is always
flood loaded and typically mounted directly to a storage device such as a hopper, bin
or silo. The amount of material discharged by a screw feeder is completely controlled
Stock Shrouds Fit by design parameters.
Easily into U-Trough A screw feeder must be equipped with a shroud for at least 2 pitches beyond the
inlet opening to prevent flooding of the bulk material past the inlet. The shroud is a
curved cover that converts a U, flared or rectangular trough into a tubular housing to
prevent bulk materials from flooding past the screw. Standard covers can be used
with shrouds. Shrouds are bolted on both sides of the trough for easy removal and
include an integrated batten bar.

Multiple Rings of Packing - Each ring of packing acts as a seal. Up to five rings of
packing can be used create a seal around the shaft.
Wide Variety of Packing Materials -The 1/2-inch square braided rope packing is
available in many different materials. Graphite impregnated packing is used in most
industrial applications. Teflon packing is used in the chemical industry and ceramic
fiber packing is used for high temperature applications.
Purge Option is Available - Flanged gland seals can be purged with air, nitrogen,
grease or other purging medium to prevent bulk materials from leaking out. An air or
nitrogen purge can create a positive pressure in the seals to overcome an internal
pressure in the conveyor or feeder.
Benefits
Creates Positive Seal Around Shaft - A positive seal is created as the packing
material is compressed around the shaft. Tightening the follower can increase the
compression force.
Protects Personnel and Equipment - Bulk materials that are hazardous, corrosive
or combustible are contained within the conveyor or feeder preventing safety issues
or equipment failure.
Ease of Maintenance -The braided rope packing can be replaced in minutes. The
follower can be removed to allow access to the packing.
www.kwsmfg.com
Very Cost Effective - Other seals on the market cost up to ten times more than a
flanged gland seal. Also, most require a purge in order to operate.
Excluder Rings Stop Bulk Material Leakage
Excluder rings are used as a secondary shaft seal to prevent leakage of bulk materials
at the drive or tail shafts of a screw conveyor, drag conveyor or bucket elevator. An
excluder ring is installed on the inside of a conveyor to prevent bulk materials from
leaking through the shaft hole in the trough end or casing. A standard seal is located
on the outside of the trough end or casing. The combination of an excluder ring on
Cut Away View Shows the inside and a standard seal on the outside almost always guarantees a leak -proof
Shape of Excluder Ring conveyor.
Excluder rings fit very tightly over the shaft and require an interference fit. After
installation, the excluder ring is pushed up against the inside of the trough end or
casing. The outside edges of the excluder ring flare out and provide spring pressure
to seal the hole in the trough end or casing.
Excluder rings are installed on every assembled conveyor at KWS. No other screw
conveyor manufacturer provides excluder rings as a standard feature.
Features
Easy to Install - Excluder rings are installed by simply tapping the excluder ring
onto the shaft with a rubber mallet.
Availability - Excluder rings are available in every CEMA shaft size and in stock at
KWS.
Positive Seal - Excluder rings provide spring pressure against the trough end or
casing

The (4) Screws are 10" Dia. x variable pitch flights which are 1/4" thick, mounted on a 5"
SCH #40 pipe which measures approx. 14' 0" long. Each screw will have variable pitch flighting
the entire length of the screw ending at the discharge. At the end of the variable pitch flighting
there will be paddles to help push the material out of the discharge. The Drive end of each screw
will be bushed and drilled for a 3-15/16" Dia. 2-bolt driveshaft. The tail end of each screw is
bushed and drilled for 3" dia. shafts. All flights are continuously welded on the pushing face, and
backside. The welds are left as laid with color and spatter removed.
The Hopper is approx. 12' long by 4' wide inside, and measures approximately 3' 4" tall. It
is constructed of 7GA 2B 304SS plate and re -enforced with 2" x 2" x'/4" thick 304SS support
angles. The bottom side of the hopper will have a 1/4" thick flange which will bolt up to the 10"
Quad Screw Feeder housing.
The Quad Screw housing is a custom style U-trough style approx. 14'-2" long fabricated
from 7GA 2B plate with 3/8" thick flanges on each end. The housing has an upper flange that
bolts up to the mating flange of the Hopper. The discharge is approx. I I" long x 38-3/4" wide
height to be determined. The tail trough end has (4) sealed up seals with (4) flange mounted
bearings mounted to a 3/8" thick endplate. The drive end has (4) sealed up seals, (4) flange
mounted bearings, (4) Spur gears in an oil sump, (2) Pillow block mounted bearings and (2)
flange mounted gearboxes, with a 5HP C-face mounted motor. The gearboxes are flange mounted
to a mounting plate which is stood off from the tail trough end plate.
The Twin screw drive consists of (2) drives mounted off the end of the screw housing, and
supported to the ground. Each drive is flange mounted to the drive mounting plate. Each set of
(2) screws runs independently at 4.5 RPM
All motor controls, wiring for the motors, starters, etc. that are required are by others.
All materials of construction in product contact will be T-304 stainless steel.
The Feeder and Hopper will be assembled and run in our shop prior to shipping.

QUOTATION Q23-143-RS
That due to the past world VOLATILITY of raw materials for the producing of Steel & Stainless
Steel a "Surcharge" has occasionally been invoiced to us by some of our Steel & Stainless steel
suppliers. This is charged to us at time of the materials shipping. If a surcharge is charged
to us it will be passed on at our cost.
NOTE: THAT THE SCREW SPEED OF AN INCLINE OR VERTICAL SCREW MAY
HAVE TO BE CHANGED AT START UP IN ORDER TO GET THE DESIRED
THROUGHPUT THIS IS DUE TO THE ANGLE OF INCLINE, THE LENGTH
OF INCLINE OR LIFT, THE NUMBER OF HANGER BEARINGS, THE
MATERIALS FLOW CHARACTERISTICS, etc. THERE WILL ALWAYS BE A
RESIDUAL OF MATERIAL LEFT IN THE HOUSING. THE AMOUNT OF
RESIDUAL MATERIAL LEFT IN THE HOUSING OF AN INCLINE OR
VERTICAL SCREW WILL DEPEND ON THE ANGLE OF INCLINE, THE
LENGTH OF INCLINE OR LIFT, THE NUMBER OF HANGER BEARINGS,
THE MATERIALS FLOW CHARACTERISTICS, THE SCREW SPEED ETC.
