Why should the nip between a die and press rollers be adjusted and how to adjust it?

The die-roller nip also refers to the clearance or space or called distance from a die to the twin press rollers respectively.

The pelletization yield without adjustment of the clearance cannot meet the due value on the one hand, and material powder will not be formed as in pellets and then swung out of the machine on the other. For the pressure force is not formed without a proper distance.

Technically, the clearance is obliged to remain 0.1mm to 0.3mm, but we human beings cannot observe exactly the space with our naked eyes. So seasoned operators of pellet mills may tell you the skip-and-touch status describing die-roller assembly rotation will be quite sufficient. Specifically, when a pellet mill is switched off, the die will be driven at a fast rotating speed, along with which the twin rollers will be forced to spin intermittently as well. The adjustment of the clearance to that end will have the pellet production reach a new high, starkly comparing with the ignorance of clearance fine-tuning.
