Crumblers HE

The Wynveen Crumblers HE 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, at equal speeds in opposite directions, and cut the pellet to a crumble.

Using accurate remote measurement, the large 300 mm crumble rollers guarantee an optimum result. Automatic roller adjustment increases the efficiency and simplifies the adjustment of the roller during production. Our crumblers HE are very efficient and very suitable to place after our Vacuum Coaters.
