Lately we are getting a lot of inquiries for our popular lab models. The application is fuel cells. Guess everyone is going green. Our lab models are being used by at least 10+ customers in making electrodes for Solid State Fuel Cells and more. Fascinating applications. Fuel cell is one of the solutions for our future energy needs.
I was fortunate to chair a technical conference about fuel cells. In this conference, I learned a lot of about fuel cells and co-edited the presentations into a book: Fuel Cell Electronics Packaging, published by Springer. Here is the link: http://www.springer.com/west/home/generic/search/results?SGWID=4-40109-22-173727516-0
Today’s commercial, medical and military electronics are becoming smaller and smaller. At the same time, these devices are packed with more functions and demand more power. This power requirement is currently met almost exclusively by battery power. A fuel cell is like a battery converting chemical energy directly to electricity. The convergence of fuel cell technology and microelectronics is enabling the new design and manufacturing of fuel cells.
Fuel Cell Electronics Packaging presents the latest developments in the technology convergence of microelectronics and fuel cells. Using the well established manufacturing methods used in microelectronics packaging, fuel cells can be further fabricated in smaller sizes with higher energy density, at a faster pace and lower cost. This book uniquely addresses this issue. Fuel Cell Electronics Packaging serves as a practical reference guide for engineers, researchers, and manufacturers of microelectronic and fuel cell products who are interested in topics such as:
- ceramic hybrid separators for micro fuel cells
- miniature fuel cells built with LTCC technology
- novel fuel cells fabricated using microelectronics technology
- fuel cell thermal management
Written by a variety of professional and academic sources, Fuel Cell Electronics Packaging is a valuable resource for those interested in the latest advances in fuel cell technology. Written for:
Scientists, engineers, and researchers interested in the development of fuel cells and microelectronic products

One of our goals in the Year 2007 is to add fun and ease to what you do at work. We operate a fun and caring organization, and we want you to benefit from this culture.
Today, we introduced a new web image to accommodate the great offers and events that are to come one after another over the rest of the year. You’ll find the new website easy to navigate, with added features such as “Free Quote”, “Customers A to Z”, and “Web Specials”, and better yet, covering a wider range of products, including used brand name machines.
In celebration of the launch of the new web interface, we are going to offer 2 free apron knife blades regardless of the make of your three roll mill. We will also invite you to “Name Your Own Price” for two web special three roll mills – a 2.5” model and a 6” model – through Ebay. You will find similar deals on our website all year round as we pass on more savings to our valued customers.
The next big thing, apart from providing better products and services of course, is to inaugurate the much expected Happy Three Roll Miller Club. As a reader has pointed out, “Why nobody thought it in the past!” We want to bring together three roll millers from all kinds of industries – ink, cosmetics, food, chemical, pharmaceutical, and many more – to share valuable experiences.
In June, we’ll invite you to post both happy and awkward three roll milling stories and ask people to vote for their favorite ones. There will also be a contest for the “Best Miller of the Year.” Winner gets a luxurious vacation for 2 to Las Vegas! As a gesture of goodwill, we also plan to donate $2 to charity for every new club membership although enrollment is totally free.
Visit us often and keep yourself informed! Don’t forget to join us for FUN!

In response to a question from a customer in Europe, I am sharing how I do the initial set up for three roll mills.
Different people have different ways of setting up three roll mills. Here is my experience and worked for me.
During the initial set up, first separate the discharge rollers by 2-3 mm, then adjust the gap of feeding rollers to about 0.050mm to 0.075mm. Then put a little paint on the rolls (about 2 cm wide) and check if the paint is running smoothly without moving to either end. Adjust the roller gap on one side if needed. Until the paint stays on the roller in one place for about 1-2 minutes, then start setting up the discharge rollers. Stop the machine and set the gap of discharge rollers to about 0.025mm – 0.075mm, then start the machine with a little paint on the feeding rollers (again no wider than 2 cm). The paint should go straight through the rollers. If needed, adjust the gap of discharge rollers on one side if needed. Generally speaking, if the gap on one side is closer than the other, the paint will move towards the smaller gap side. If the rollers are perfectly parallel, the paint should go straight.
What is your experience?

Today we heard from our friend Mr. Mario from Croatia (nime1@net.hr). He is very satisfied with our machine. It was not easy to ship a machine to Croatia from the US. Originally we were going to ship by ocean to Triste, Italy. It was going to take 35-40 days. Finally we decided to ship by air to Zagreb. Customer satisfaction is very important to us.
A good day with another satisfied customer!

Last week a US 16×40 three roll mill customer asked for detailed instruction for lubrication.
In our Owners’ manual, we wrote:
machine lubrication and maintenance
The machine has sealing lubrication structure for the gears. It is required to add industry gear oil; the oil lever should reach half of the oil gauge. It can not add more than that to prevent the oil from spraying out. The bearing base has been added oil before shipping, it is unnecessary to put more oil in for the new machine first time operation. After running 120 hours, the oil can be injected by oil injection tool.
- The lubrication oil must be added into transmission axle through lubricating nipple.
- Lubrication oil should be added very often at those places, such as: every adjusting screw, high/low speed roller bearing base and base orbit, to prevent the gear teeth from choking.
- One major maintenance shall be carried out after six month continuous operation. Dismantle all those moving part and clean it. Apply new oil and inspect the oil cycling situation. Correct the problem if it is found.
- If the concave area in the middle part of roller is found, surface material exfoliating or distortion is found, please stop operation and repair it immediately.
- If the roller is repaired too many times and the roller diameter is more than 1.5mm smaller than nominal diameter, the gear transmission will conflict so that it will make the gap between rollers too big to grind the material well. The gear must be repaired under this condition to reduce its diameter, or the roller must be replaced.
- The collecting blade edge must be very sharp and smooth. Burr and split are seriously prohibited. When the blade is short, just loose the screw to move the blade out. If the blade is finished and you change a new blade, please choose the right hardness usually between 30HRC and 40 HRC.
- If the mill has not been operated for a long time, please apply anti corrosion grease on roller surface and other related place to avoid stain and pinhole. Thorough inspection shall be carried out before next operation.
- If the cooling water flows into the machine, it means that the cooling water flow is too strong. So the incoming water controlling valve should be closed a little bit, and meanwhile loose the water drainage screw, let the water inside gear box flow out and increase the size of water drainage hose.

Today our customer from Ace Polymers asked the following question:
The tip of end plates for the lab model was slightly bent during the shipping, will it scratch the rollers?
The rollers are made out of hardened steel (hardness HR 70). The end plates are made out of tempered brasss (hardness HR <10). The end plates will not scracth the rollers.
