Summary:
Scientists from both the Department of Electrical Engineering at the University of California and the Advanced Material Research Center at the Samsung Advanced Institute of Technology have discovered that three roll milling yields advanced electromagnetic interference shielding for carbon nanotube (CNT) composites. These researchers used a Torrey Hills three roll mill to guarantee successful assimilation and distribution of intertwined multi-walled carbon nanotubes (MWNT) in their polymer matrix. A stable and even dispersal is essential in achieving maximum efficiency in electromagnetic shielding for CNT/polymer composites.

Summary:
Carbon nanotube (CNT) and polymer composites are very important to multiple industries, including aerospace, energy, electronics and many more, due to their strong durability as well as superior electrical and thermal conductivity. A Torrey Hills three roll mill was used to disperse dry CNTs into a silicone resin, so that researchers could compile orientation and dispersion indices with an image analysis technique. These indices will allow the properties of CNT/polymer composites to be more easily predicted, so that their microstructure can be optimized.

Summary:
In a study aiming to compare nanocomposites made with volatile solvents to silica nanocomposites made with a room-temperature ionic liquid (RTIL) preparation strategy, researchers in the Department of Chemical and Biological Engineering at Drexel University adjusted a Torrey Hills 2.5 x 5 three roll mill lab model to the precise specifications needed (a gap of 20 microns between the 2.5’’ diameter rollers, and a surface speed of 31, 84 and 174 RPM, in this case). The RTIL nanocomposite preparation proved to be an effective alternative, which may help improve the structural strength and electrical conductivity of thermosetting polymers, such as epoxies.

Summary:
Researchers used a Torrey Hills three roll mill to disperse surface modified and unmodified carbon nanotubes (CNTs) into an RTM-grade (resin transfer molding) epoxy resin. They discovered that dispersing C100 nanotubes by three roll milling led to increased electrical conductivity in the final composite structure. This exciting research will help improve aerospace grade composites so that they have superior electrical capabilities.

Summary:
Aiming to investigate how to best transfer the valuable properties of carbon nanotubes (CNTs) to polymer nanocomposites, researchers from the Composites Centre at Cranfield University milled dry C100 nanotubes and surface activated nanotubes into a resin with a Torrey Hills three roll mill, so that Resin Transfer Molding (RTM) could be performed afterwards. Studying the RTM of glass and carbon epoxy composites that contain dispersed carbon nanoparticles has helped scientists understand that CNTs must be consistently dispersed into a homogeneous polymer in order to best yield high electrical conductivity and advanced thermal properties.

When and Why Do I Need Cooling for Three Roll Mill Rollers?
A client who intends to use three roll mill for algae exfoliation visited our lab the other day, trying to process several kilos of algae harvested from the Norwegian sea. We seldom use our demo lab model to do large samples like that. However, they explained that only a small amount of oil can be extracted and they need a significant amount to test the results. For such a novel application, we gladly agreed.
As the milling went along, the rollers, which are made from stainless steel, got warm and raised the concerns of our client. They want the rollers to stay below 40°C to prevent the algae material being oxidized. And we had to turn on the cooling system, which can maintain the roller temperature ±2-3°C around ambient temperature.
It is very common for rollers to get warm after a prolonged period of continuous running. The roller surface temperature increases as a result of heavy friction between the rollers brought by the high shearing force necessary for successful grinding. When the surface temperature exceeds 70°C, damage to the gear system might occur. Under such circumstances, active water cooling is recommended. If, in this customer’s case, a certain temperature is required to prevent deterioration of the material, water cooling is of utmost importance as well.
Last but not least, although we call it water tank, water is not the most desired liquid for the job. We recommend the use of at least 50/50 coolant and water. Coolant with anti-corrosion additives, such as this one, includes a corrosion inhibitor that balances the negative acidic effects that can develop over time in antifreeze and water solutions. It also stabilizes the pH level which helps reduce rust and prevents electrolysis, mineral deposits and pre-existing scale build-up from forming resulting in potential core damage for long term protection.

The mechanism behind water cooling is not a complicated one. As you can see in the illustration above, water is first pumped into the built-in water tank on the machine, usually with a submersible type pump (so that it can be placed in a larger water container for recycling). This cooling water goes in through the pink tunnel and flows into the blind hole inside the roller. The blind hole is designed with a slight slope so that water eventually flows back into the water tank. There is a water outlet through which warm water gets out of the tank. The water recycles in and out of the larger water container, such as a bucket, and does it job keeping the desired temperature. Be sure to adjust the water flow by controlling the pump to keep the liquid level constant in the water tank. The same system can be used to heat up the rollers if hot liquid is pumped into the rollers.

Maximize Ointment Mill Throughput
Topical formulations greatly reduce the risk of side effects caused by oral medications, offering the potential to deliver at the site of inflammation while
minimizing systemic concentrations. As a result, the demand for pain creams has increased
significantly. One pharmacy asked us to help optimize
the output of a lab model ointment mill they bought from us, hoping to make 80kg
of creams daily.
What we thought would be a simple task of adjusting
the speed or the gap sizes turned out to be a full-scale lab experiment. The
ointment pre-mix was so thick that it required an unusual combination of front
and back gap settings to make it work. Even so, the hourly output was still
significantly lower than other types of creams due to the material property. Here,
we want to introduce the scientific method our engineer utilized to maximize throughput,
so that customers can make the most out of this award winning lab model
ointment mill.
Our engineer first observed the behavior of cream on
the roller. The initial setting was 50 microns for both gaps. The cream was
slow running into the feeding area and was stuck on the middle roller which
meant bad transfer to the fast roller and the hence collection blade. The
conclusion was that the gap between the slow and middle roller should be wider,
while the gap between the middle and fast roller should be narrower. After a
few rough adjustments, our engineer decided to fine-tune the gap settings with
a series of experiments.
He started from 150-micron back gap (gap between
slow roller and middle roller), and 20 micron front gap (gap between middle roller
and fast roller). First he needed to confirm for this particular kind ointment,
higher speed lead to higher output. As it turned out in experiment 1to 3,
higher speed did lead to higher speed, and the maximum speed didn’t cause the
material to splash. He would use maximum speed for all the rest of the
experiments.
Next step, he adjusted the front gap to 30 microns.
The transfer from the middle roller to the fast roller got worse and the throughput
was down. In experiment 5, he kept the front gap at 20 microns and used a narrower
gap (100 microns) between the slow roller and middle roller. The throughput was
down again, which meant the back gap needed to be wider. After a total of eight
experiments, he settled at 250-micron back gap and 20-micron front gap. Our
customer was able to reach their desired output as a result.

Anyone using an ointment mill, or a three roll mill as other industries call it, with the goal of maximizing its output, can give
this optimization process a try. Contact us if you have questions on how to do
it successfully.

Our Lab Model Three Roll Mill Named as Finalist in the 5th Annual 2013 Golden Bridge Awards for New Products and Services!
Our Torrey Hills T65 (2.5x5) three roll mill was named as a finalist for the 2013 Golden
Bridge Awards under the category of New Product and Service. Golden Bridge Awards are an annual
industry and peers recognition program honoring Best Companies of all types and
sizes in North America, Europe, Middle-East, Africa, Asia-Pacific, and
Latin-America, Best Products, Innovations, Management and Teams, Women in
Business and the Professions, and PR and Marketing Campaigns from all over the
world.
We started
from the vision of a compact, robust, and continuously feeding mixing device
that blends viscous materials. The patent pending overall design is visually
appealing. Under the hood the revolutionary mechanical driving system delivers
high shear force with minimum operating noise. We crafted the rollers with 5μm
concentricity and 0.5μm surface finish for precise applications. The rollers are cored
for either cooling or heating to keep the temperature at the desired level. We carefully matched the electrical components and bearing
systems to maximum the power, dispersing efficiency, and throughput. A VFD is
used to provide variable speed control. As a result of these innovations,
minimal particle size milling down to submicron level occurs. An easily
accessible pull switch adds extra operator protection. This mill is positioned
as a leader in mixing tool for a wide range of industries including paints,
inks, thick film pastes, adhesives, coatings, ceramics, cosmetics, food, and
pharmacy compounding, with comparative advantages in mixing efficiency,
continuous feeding capability, and quality control.

Ointment Mill - A New Focus of Interest
An engineering colleague and I went to visit a pharmacy compounding customer last week. Three roll mill used in pharmacy compounding has become a hot sale since the beginning of this year. Exakt 50 used to be the standard equipment to make medicated ointment. However, more and more pharmacies are expressing their concerns about its productivity limit and turning to us for ointment mill solutions. We are excited and ready to give our best to this market.
This particular compounding pharmacy in California is doing extremely well and seeing more ointment orders by the month. Their focus is on pain and hormone ointments. Surrounded by friendly pharmacists and technicians, we offered a two-hour long product training session, letting them learn the best gap size for their particular kinds of ointments in order to maximize output. This 2.5x5 three roll mill lab model, which potentially doubles the output of that of Exakt 50, turns out to be the perfect tool for them to fulfill their monthly orders.
Apart from the 2.5x5 model, our 6x12 model has also generated plenty of interest from pharmacy compounding market. From pain ointments to anti-aging creams, our customers found it to be a great pilot production tool for the expansion of their businesses.
