UNIT DESCRIPTION
7.1. FUNCTIONAL PRINCIPLE
The machine disperses, de-agglomerates and homogenizes powdered
material to liquid or highly viscous suspensions. At the same time the
product is degassed.
The three rollers rotate reversely with various speeds in a speed ratio of
approx. 1:3:9.
Roller 3 (
c
) has the highest speed.
The product is supplied into gap 1 (
a
) where it is pre-dispersed.
Then the product is supplied to gap 2 (
b
), where the final dispersion takes
place.
The scraper knife (
d
) scrapes the product from roller 3 (
c
), and the product
flows off via the scraper socket (
e
).
The fineness of the final product can be influenced by various gap settings,
speed settings and the number of passes.
