Method for pressing and forming a raw material into a granulated material and an apparatus thereof

A method for pressing and forming a raw material into a granulated material by a pair of rolls, the method comprising the steps of:

• feeding a raw material into a space between a pair of rolls that have a predetermined number of holes for forming the granulated material on an outer surface thereof, wherein pressing pins, which are inserted into respective holes, and a predetermined number of members for supporting the pressing pins are installed in the rolls, the members for supporting the pressing pins being configured to be separate from the pressing pins so that the pressing pins slide on the members for supporting the pressing pins;
• pressing and forming the raw material into the granulated material by the pair of rolls;
• and
• ejecting the granulated material by the pressing pins as the pressing pins slide on the members for supporting the pressing pins.
