Crumbler

The Ottevanger’s crumble technology is based on two large,
independently driven rollers. That ensures an optimum
result of minimum fines with maximum crumble.
An integrated control valve ensures an even flow to an
axially riffled proportioning roller, manufactured from solid
steel. Large-scale axially and radially riffled crumble rollers
rotate slowly, at different speeds in opposite directions, and
cut the pellet to a crumble.
Using accurate remote measurement, the large 300mm
crumble rollers guarantee an optimum result.
Automatic roller adjustment increases the efficiency and
simplifies the adjustment of the roller during production.
