SIZE REDUCTION AND SIZE SEPARATION

SIZE REDUCTION AND SIZE SEPARATION

The roller mill has two cylindrical rolls of stone or metal, mounted horizontally, which are capable of rotating on their longitudinal axes. One roll is rotated directly and the other rotates freely. When material is placed above the rolls it is drawn in through the nip and the second roll is rotated b y friction. ... The fine particles pass ...

The forming roll can be replaced by a dandy roll with a pattern used to make a watermark on the paper. 4. Suction Roll and Felt. The paper passes through a suction roll in order to remove as much water as possible before arriving at felt section to start the drying stage. At that time, the sheet contains approximately 50 to 60% humidity/moisture.

The use of beads packed and agitated allow to absorb a lot of power and mill the particles to few dozens of microns. In order to separate the beads and the product at the end of the mill, a grid is placed, with hole diameters lower than the beads one. It is important to consider that agitating beads, especially if they are densely packed in the milling chamber, release heat. These mills must ...
