2. Introduction
Garrett Griffith
Sophomore at Arkansas Technical University in Russellville
Electrical Engineering Major
From the White Hall/Pine Bluff Area
First summer here at Evergreen
4. Roll Data Project Objectives:
Understand how paper is made
Compile information for all rolls on PM2 including Diameter, Cover, Shell, Roll
I.D., Crown, Cover Type, Bearings, Materials, ect.
Obtain same information for all spare rolls
Check for accuracy
Place information into Excel Spreadsheet
Learn how to use SAP and get information into program
Configure a specific spreadsheet for use by Kevin Kidder and Bill Wilson, it
will be maintained by them after completion.
5. • I spent a
considerable
amount of
time looking
through
drawings for
information
on the rolls
7. Roll Project: Current Progress
We definitely underestimated the amount of
information on the rolls
Still in the information gathering phase for the
SAP aspect
Next step will be to learn SAP and implement
information there
Spreadsheet for Kevin and Bill complete
8. Flowmeter Project Objectives:
Determine where the Mill’s water goes
Elizabeth began by placing ultrasonic flowmeters on various pipes in the mill
to detect flow
Out of the 16 placed, 2 did not get a reading
The Unfiltered White Water Pipe and the Filtered White Water Pipe (UFWW &
FWW) did not deliver a reading
Also a flowmeter will be installed in Manhole H on the Boulevard Sewer
I took over the Mill Water Usage Monitoring System Project from Elizabeth
Lott due to pregnancy
9. Using Siemens Portable Flowmeter
I also learned how to utilize specific instrumentation this summer
Using the Siemens
Portable Flowmeter to
measure flow on power
house fire water pump
7/8/14
10. Flowmeter Project: Current Progress
We proceeded to try different manufactures
flowmeters to determine if it was a mechanical
failure that caused no reading
We determined that there was not enough water
in the pipe to use an ultrasonic flowmeter
Orifice plates were then selected
Installation was completed by Turner
Electrical Work was completed by Evers
14. Flowmeter Project: Current Progress
After setting up Process Control we discovered that the measured flow
was outside of the transmitter’s ranges
Higher ranged transmitters were selected and received from the
storeroom
When Rudy (Experitec) and I got ready to install the new transmitters
it was discovered that the low side valve of the orifice plate was
closed. This caused backpressure that sent a reading of much higher
flow than was actually the case. Also one of the transmitters was
ranged wrong to begin with on the instrument side
After fixing the mistakes and watching the readings for a couple of
days, all readings are normal, accurate, and in range
15. Manhole H Flowmeter Progress
Began discussion with Rudy de Anda of Experitec
for specifications of manhole and outfall
This flowmeter will be wireless with a ten year
battery lifespan and utilize a wireless gateway
Currently waiting on parts to arrive
Next step: install flowmeter, mount gateway and
run cat5 and 24V power to caustic plant rack
room, then incorporate into PI
17. Core Shrinkage Study Objectives:
Evaluate the normal shrinkage of a core for
the extruders
Determine a way to minimize core
shrinkage or at least get some data from
which we can adjust our asking cuts on the
cores
18. Core Shrinkage Study Course of Action
A meeting was conducted with Sonoco, Nero Haralalka,
Rob Luter, Andrew Blue, myself, and others to determine
a way to accurately measure shrinkage
Our plan was to go to Sonoco and measure 27 cores of
different lengths and ages and bring the back to the mill
to be measured periodically in different areas of varying
moisture and temperature
The cores were placed in the core room, humidity lab,
and also on the wet end. They were measured in the
same 4 positions twice daily for a week while recording
temperature, humidity, and time

Results of Shrinkage Study
All measurements had strong
correlation to one another.
Based off of this information we
were able to adjust our asking
cut accordingly.

dream work!

Observing the
base of a
pump
Looking up

all of our
projects
22. What I have learned
Incorporating what I have learned at school into the real world is the most
important thing I have taken from this summer at the Mill
From talks with people like Mike Cottrell I have gained a better understanding of
all things electrical
There is a lot that goes into making paper
This mill spends a ton of money
How to do real research
Project Management
Not all flow meters are created equal
How to ask for help
How to look up a loop sheet
It is always better to go in the field and look with your own eyes
How to write a Requisition and Purchase Order
Double check EVERYTHING
