An integrated control valve ensures an even flow to
an axially riffled proportioning roller, manufactured
from solid steel. Large-scale axially and radially riffled

opposite directions, and cut the pellet to a crumble.
Using accurate remote measurement, the large 250 mm
crumble rollers guarantee an optimum result.
