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

Recently, a lot of our customers are milling electronic materials and the most advanced materials are growing strong.

The materials are milled into polymer systems first before any other solid component is introduced into the batch.

Rolls are precision-machined, mirror like cylindrical surfaces and the gaps can be adjusted all way down to 0um, and rotated at slow speeds.

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.

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.

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

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.

They are widely used to mix electronic thick film inks, high performance ceramics, cosmetics, plastisols, carbon/graphite, paints, printing inks, pharmaceuticals, chemicals, glass coatings, dental composites, pigment, coatings, adhesives, sealants, and foods.
