Rotochopper rotor with pocket-loc mountsRotochopper rotor with pocket-loc mounts

Rotors

Each of our horizontal grinders is available with multiple tooth and rotor styles to maximize efficiency, versatility, end product control, and wear life. Our specialized grinding equipment, the CP-118 Chip Processor and RG-1 Asphalt Shingle Grinder, utilize rotors designed specifically for their unique applications.

Replaceable Mount Rotor

The patented replaceable mount rotor simplifies maintenance and increases versatility by allowing operators to easily swap tooth mounts. This user-friendly rotor is much more rugged than weld-on mounts, yet far simpler than pinned disk style rotors and other replaceable mount designs. Each mount locks into the drum with two bolts—no bushings, lock collars, or heavy shafts, and no need for specialized tools like rod pullers. A unique mounting design transfers impact stress to the rotor drum, minimizing bolt stress. Each mount is independently secured, so if one mount is damaged, only one needs to be replaced. Available for: B-66, B-66 E, FP-66, RG-1, & RG-1 E.

Rotochopper two-bolt indexable rotor configurationRotochopper two-bolt indexable rotor configuration

Indexable Two-Bolt Rotor

The indexable rotor offers the versatility for processing diverse feedstocks, including pallets, slabwood, brush, wood chips, round wood, agricultural residue, and green waste. The indexable rotor is available with a range of teeth to match different feedstocks and end products. For contaminated materials, check out the single bolt indexable rotor. Available for: MC-266, MP-2, & SB-24 E.

Rotochopper single-bolt indexable rotorRotochopper single-bolt indexable rotor

Single-Bolt Indexable Rotor

For feedstocks that contain contaminants, such as rocks and steel hardware, the single bolt indexable rotor offers enhanced tolerance for impacts, along with the same versatility as the two-bolt indexable rotor. (If you need to process heavy contaminants, check out our line of slow-speed shredders). The single-bolt design minimizes tooth loss and damage to tooth mounts. Available for: EC-256, EC-366, MP-2, & MC-266.

Rotochopper wood grinder with biomass rotorRotochopper wood grinder with biomass rotor

Biomass Rotor

The biomass rotor is a highly specialized grinding solution for forestry slash, brush, and round wood. Featuring forestry disk saw (hotsaw) style teeth, the biomass rotor blends advantages of grinding rotors and chipper drums, offering a more efficient cutting action than traditional blunt grinder teeth, while providing a better tolerance for light contaminants than chipper knives. Disk saw teeth are widely used in feller bunchers and other forestry equipment, making them economical and easy to replace. The biomass rotor tends to produce a chunkier product with clean cut edges rather than frayed edges of a shredded mulch-type product. Available for: MC-266, EC-366, MP-2, EC-256, & SB-24 E.

Rotochopper pocket loc rotorRotochopper pocket loc rotor

Pocket Loc Rotor

The Pocket Loc rotor is a high-efficiency solution for low-horsepower grinding applications, such as a grinder set in-line with a sawmill. This unique rotor design allows steady grinding without plugging for compact and mid-size Rotochopper grinders that are equipped for lower volume feed rates. For higher horsepower applications, check out the single bolt or two-bolt indexable rotors available. Available for: SB-24 E, EC-256, MP-2, EC-366, & MC-266.

Shingle Grinding RotorShingle Grinding Rotor

Stump Grinder-Style Rotor

This unique rotor uses stump grinder pockets and Greenteeth® inserts to offer an unbeatable blend of simplicity, wear life, and cost-effectiveness. Scaled to the needs of arborists, our Wood Chip Processors feature this technology that is common to the tree care industry. Available for: CP-118.

Rotochopper RG-1 shingle grinding rotorRotochopper RG-1 shingle grinding rotor

Shingle Grinding Rotor

This highly specialized rotor is designed exclusively for the demands of grinding asphalt shingle waste. The unique sweptback angle of the teeth keeps shingle waste forced against the screen for continuous, efficient grinding. The teeth are arranged in a non-directional pattern to keep wear focused on replaceable parts, unlike spiral rotor designs that push abrasive fines into the grinding chamber walls. Tooth bolts are inserted from the back to prevent exposure to abrasives. Available for: RG-1 & RG-1 E.
