Rotor with 3 x 3 (MAS1)or 8 x 3 (MAS3) Staggered Knives

Advantages: - Excellent regrind quality - The staggered rotor knives offer the optimal solution to “pull” parts into the cutting chamber. - The cutting force is distributed across several high-alloyed, hardened rotating knives that provide a simple scissor cut for added energy savings, along with low-noise operation and high cutting performance. - Rotating knives can be sharpened several times depending on the amount of wear. The cutting geometry of the knives allows them to be changed without any additional adjustment. - The two fixed knives can be turned four times before replacement. - Minimum downtime when changing the knives - Fast and simple cleaning

Open Rotor with 3 Movingand 2 Fixed Knives

Advantages: - The granulators produce high quality regrind and minimize dust. - A pre-adjustment gauge is included with each granulator to allow easy, quick adjustment of the knives for optimal cutting clearance. - The slanted open rotor moving knives combined with two inclined fixed knives provides a double scissor cut that once again improves the quality of the regrind and minimizes dust. - Optimal circulation of air within the cutting chamber prevents thermal degradation of the molecular structure or melting of the material. - The patented tensing clamps of the rotor knives ensure an easy cleaning procedure and maintenance. - Fast and easy cleaning
