The gap between the rollers and the die determines the granulating effect of the stock and amount of wear on the parts. This gap is typically set at 0.05 to 0.3 mm. If the gap exceeds 0.3 mm the material will spread in a thick and nonuniform manner across the die causing poor pellet quality. A gap smaller than 0.05 mm causes unnecessary wear on the pellet press

GEMCO's machines can be easily adjusted with a hex key; adjust both screws evenly in each turn.
