No comparison to THT’s Three Roll Mills

Posted in Lubricating at 5:45 pm by Administrator

When comparing three roll mills with other machines, our mills at THT are the easiest to clean and have less residue from processed material that get left behind on the surface of the rolls. Our Three Roll Mills at THT are the easiest to clean due to the simple structure and shape of the rollers. The temperature of processed materials can be controlled by the cooling/ heating system that comes with each and everyone of our mills! Like us on FB www.facebook.com/torreyhillstechnologies


Processing Materials with Three Roll Mills

Posted in Lubricating at 8:21 pm by Administrator

Three roll mills are great for processing materials with medium to high viscosity. Recently, a lot of our customers are milling electronic materials and the most advanced materials are growing strong.

Ultrafine Components and Three Roll Mills

Posted in Lubricating at 6:07 pm by Administrator

Three roll mills are recommended for dispersing ultrafine components such as carbon black and fumed silica. The materials are milled into polymer systems first before any other solid component is introduced into the batch.


How to Disperse High Viscous Materials

Posted in Lubricating at 9:38 pm by Administrator

Three roll mills are used to disperse high viscous materials; our mills have a 3-roller configuration. Rolls are precision-machined, mirror like cylindrical surfaces and the gaps can be adjusted all way down to 0um, and rotated at slow speeds.


The Minimum and Gap Setting Between 2 Rollers

Posted in Lubricating at 5:13 pm by Administrator

The minimum can be close to 0, however, given that rollers heat up over time if not cooled, we recommend 75/50 micron gap size. There should definitely be some gap so that material can flow through and shear force can work. In addition, besides material not being able to flow through, rollers should not touch, as they will damage each other.


Three Roll Mill Gauges

Regarding our three roll mill gauges: there is no gauge that can give specific readouts of the gap distance, however, distance is easily set using a feeler gauge. Included with every order is a set of feeler gauges at no cost to the customer. Four hand wheels to adjust the rollers make it easy to use. We know that many operators are proficient enough on the mill to tell the gap distance just by looking at the gap.


THT Standard Roller Material

Posted in Lubricating at 4:54 pm by Administrator

Our standard roller material is chilled cold cast iron. It is not prone to rust, but any metal can rust, even stainless steel. For longevity, for any roller material, it should be cleaned at the end of the day. For metal rollers, except alumina or ceramic rollers, if it is not going to be used for a while, protective oil should be applied. A few customers need Al rollers if their product is sensitive or reacts to metals. Some electronic pastes, and lotions could react. make sure to “like” us on Facebook www.facebook.com/torreyhillstechnologies


An example of what a customer used to cool rollers

Posted in Lubricating at 4:33 pm by Administrator

Using a garden fountain pump like this one in Home Depot:
He used a 5 gallon pail with 50-50 diluted antifreeze coolant and used a pump similar to this one to pump cooling water into the three roll mill cooling system. It was very impressive.
