The adjustment of roller gap of a feed pellet millHaving correctly installed the die, it is necessary to adjust the gap between thedie and roller of your feed pellet mill to a proper range, which is vital forpelletizing production. Usually, proper roller gap is 0.1 mm to 0.3 mm. With anoptimal gap, the rollers only hit high spots on the die when the die is turning ata low speed.Generally, for new die and new rollers the gap should be larger than the oldgap. For a die with large openings, the gap should be larger than that withsmall openings, and for a formula with ingredients that are easy to pelletize,the gap ought to be larger than the one that is hard to pelletize. In addition, atthe beginning of using a new die, especially one with small openings, a largergap is favorable for easier running and to avoid rolling press on the die.Consciously accumulating experience for gap adjustment during productionpractices is good for a pellet mill operator’s professional growth. To increasethroughput by minimizing the roller gap to zero or even negative clearance isinadvisable since the ring die may crack as a result of the high amount ofstress on it.Welcome to contact us for more feed pellet mill information and technicalsupport.
