Laboratory Triple Roll Mill

DESCRIPTION

Three roll mill is mainly used for refining high viscosity material in oil paint, printing ink, color paint and plastic industries. It is especially suitable for processing material with high viscosity and fineness. Three rolls run at different speeds and materials are squeezed into the spaces between different rolls in order to realize the effect of grinding and refining.

Operating principle:

The three adjacent rolls of a three roll mill (called the feed roll, center roll and apron roll) rotate at progressively higher speeds. Material, usually in the form of paste, is fed between the feed roll and the center roll. Due to the narrowing space between the rolls, most of the paste is rejected to the feed region. The part that makes it through the first in-running nip experiences very high shear force. Upon exiting, the material that remains on the center roll moves through the second nip between the center roll and apron roll, which subjects it to even higher shear force due to the higher speed of the apron roll. A knife blade then scrapes the processed material off the apron roll and transfers it to the apron.
