Crumblers HE

The Crumblers HE-serie is a new crumbler line based on years of experience with a focus on high performance and high efficiency.The Ottevanger crumbler technology is based on two large, independently driven rollers. That ensures an optimum result of minimum fines with maximum crumble. An integrated rotating feeder ensures an even distribution of the pellets to the crumble rollers. Large-scale axially and radially riffled crumble rollers rotate at equal speeds in opposite directions, and cut the pellet to a crumble. Using accurate measurement, the large 300mm crumble rollers guarantee an optimum result. The remote roller adjustment increases the efficiency and simplifies the adjustment of the roller during production.
