Data Analysis on Designing a Double Roller Granulator

Last decade, specialists have done some theoretical analysis on double roller granulator.  And they have got some results about designing a double roller granulator.

The data items are as follows:

1. friction effective angles of powder material;
2. frictional angle between the roller and raw materials;
3. compressive factors of the raw materials;
4. pressure limit, under this limit, the raw material can be pressed into pellet.
