The Home of Happy Three Roll Miller
Recently we visited our customer using our Three Roll Mill to make lipstick destined for Wal-Mart. They shared their preferred method to clean rollers using Mineral Spirits, or also known as White Spirits. They said this mild solvent is great for cleaning up oils and greases, so great for lipsticks. Also, this low volatility petroleum distillate is inexpensive, and safe.
At Torrey Hills Technologies, we have excelled in customer service throughout the years by successfully providing our customers with solutions to difficulties they encountered while operating our machinery. We attempt to address any concerns or issues on a case by case basis. However, for the sake of efficiency we took the time this week to make a list of the most common problem and pertinent solutions condensed into the most simplistic form. The following troubleshooting tips are general guidelines for approaching frequently occurring issues:
1. Cooling
The rollers are cored to take cooling water. When planning to use the machine consecutively 30 min or less, there is no need to connect it. If cooling water is needed, use automotive antifreeze coolant and use a small immersion pump to pump water into the rollers. If the water is leaking into the three roll mill, it indicates the leak of the current is too strong.
2. Material is leaking from the side
Normally, there are two causes for leaking at the side:
I. The rollers are not parallel. The more narrow side will have
paste leaking out. Please adjust accordingly.
II. The end plates do not fit on the rollers tightly. The rollers are
machined to +/- 0.002- 0.005mm tolerance concentricity. The
end plate arcs are grounded similarly. However, these do not
have an exact match. When the roller gap changes, the gap
between the roller and end plates will change at the same time.
When you set up, please use one hand to press the end plate
against the roller and then gently tighten the screw to fix the end
plate position. Do not over tighten the end plate screw. After a
few months’ use, the end plates will match the roller very well.
3. Transmission making noise
If the gears make noise during operation, the gears could be misaligned. Since the distance between rollers are adjustable this allows the gears to also move. If the rollers are not rotating parallel to each other, it will cause the gear to misalign and make noise. It should be corrected immediately to prevent any damages to the gears.
4. Resistance when adjusting bearing blocks or freeze bearing block
When the machine is used for an extended period of time, some of the material could leak into the sides of the rollers and spread into the bearing blocks. It will cause resistance when adjusting the rollers and in some cases the rollers can freeze if the problem is not taken care of. Proper cleaning and lubrication will be needed and should be performed according to manufacturers’ suggestions.
5. Poor Grinding:
This can be caused by the following.
I. The vehicle and pigment are not properly and thoroughly
mixed.
II. If the paste is too thin.
III. If paste is leaking off both ends of rolls.
IV. If the rolls are set too far open
6. Motor Overload
This can be caused by the following:
I. Check if the voltage on power line is low by testing it at full
load.
II. Again, make sure the paste is mixed properly.
III. Not having enough lubrication which heats up bearings.
IV. When parts (Apron or guide blocks) are pressed too tightly
against the rolls.

Everyday I interacted with many customers. It is truly a privilege to have a chance to know them and serve them. Today I learned something important from a customer, Mr. John Murtaugh from
TWO BIRDS ANTIQUES
Here is a brief description of Two Birds Antiques
Angela Kier and husband John Murtaugh began Two Birds Antiques in 1997. The couple became fascinated with 18th Century English ceramics in 1989 after the purchase of a piece of 1770’s Wedgwood creamware. They created Two Birds Antiques not only as a business but also as a way to connect with other individuals who share a passion for ceramics, their philosophy is simple… Treat each customer as a friend (most end up that way) and stand behind each item with a guarantee. Two birds Antiques exhibit at shows across the USA. We do not have an open shop but are available by appointment to both buy and sell. Angela is a candidate member of the American Society of Appraisers- The international Society of Professional Valuers.
What struck a special cord in me is their business philosophy: Treat each customer as a friend (most end up that way) and stand behind each item with a guarantee. What a beautiful and heartfelt statement. John, thank you for giving us a chance to serve you.
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!
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!
