Highly compact and portable, the MP-2 offers standard features, like an on-board colorizer, that you wouldn’t find in other company grinders (or even larger grinders).

  • Advantages

    Grind & Color System

    Standard on the MP-2 our Generation II Colorizer System maximizes quality while minimizing costs by injecting colorant directly into the grinding chamber to produce mulch with the right size, texture, and color.

    Screen Installation System

    Our patented system allows operators to quickly change screens – reducing downtime and enhancing versatility – without needing overhead lifting equipment, fasteners or special tools.

    Transition System

    The infeed to grinding chamber transition system forces loose particles into the rotor for one-pass grinding, maximizing efficiency and simplifying maintenance.

    Simplified Maintenance

    The MP-2 offers fast, easy access to the grinding chamber and all maintenance points, along with time-saving features that limit downtime.

    Precision Grinding

    With the MP-2, we’ve cut the weight and size without cutting the “Perfect In One Pass” simplicity that defines the Rotochopper brand.

    Unmatched Maneuverability

    Compact enough to tow with a two-ton truck, the MP-2 sets up in minutes to produce colored mulch, compost, and other commodities.

  • Exclusive Features

    Loading Conveyor

    The MP-2 has an optional folding truck loading conveyor that allows users the ability to fill an open top semi trailer, then easily fold up for transportation purposes.

    Cross Belt Plate Magnet

    This optional magnet, positioned above the discharge conveyor, provides effective removal of ferrous metal, such as pallet nails.

    Slab Ramp

    Simple to adjust, this patented system offers unique control for pliable feedstocks to maintain steady grinding without overfeeding.
