Grinding is the most common method used to reduce the size of wood wastes. Wood tub grinders are used to reduce wood wastes into smaller particles. No screening is necessary. The larger-sized output material from the tub grinder can be used as a biomass fuel or as a bulking agent to balance high nitrogen loads in composting operations.

The wood tub grinder can process large trees and finished lumber.

End-Product Types. A hogged product is generally a coarse, multi-sided, frayed wood particle.

Hog applications include the following: production of hogged fuel, mulch, compost and soil amendments, bulking agents, and products for other low-quality applications and composite panel-board feedstock.

Using Hogs in Two-Stage Processing. Also, hogging equipment use is during the first stage of a two-stage size reduction. In this configuration, the hog produces coarse chunks of wood, which are without hard contaminants, then directed to a re-chipper or hammermill for secondary processing.
