Horizontal Wood Grinding

Horizontal Grinders were first introduced in the late 90’s as an alternative to the tub grinder. Similar to tub grinders, there are a variety of sizes and horsepower, designed to handle land-clearing debris, bark, brush, logs, stumps, wood construction and demolition (“C&D”) material,leaves, etc. Horizontal grinding reduces or recycles wood and green waste.

Many operators produce salable products such as mulch, colored mulch, boiler fuel, and compost. Others use their grinder to reduce the volume of green waste material to minimize trucking costs and save on fuel and dump or tipping fees.

In contrast with the tub grinders, horizontal grinders use a positive-feed design to feed material into the hammermill. The most common type of horizontal grinders utilize a long, narrow infeed with a belt, chain, or slats and an infeed roller that feed material horizontally into the mill; thus the name “horizontal grinder”.
