Grinder converts stumps to biomass feedstock

March 11, 2021

WSM’s 5472 Titan Horizontal Grinding System converts large-diameter stumps, round wood, branches, storm debris, land clearing, and other wood residuals into biomass feedstock.

The system processes rubberwood and wood stumps at rates up to 50 metric tons per hour to an approximate four to six inches minus biomass feedstock.

The Titan Grinding System starts with a heavy-duty chain infeed conveyor to meter the material to the powered feedroll. The 40-inch-diameter pivoting powered feedroll provides superior climbing ability to feed material to the Titan Horizontal Grinder.

The grinder’s 54-inch-diameter by 72-inch-wide rotor assembly includes hammers that weigh 195 pounds each and have replaceable tips. The pivoting grinder housing allows for easy maintenance access to the rotor and screens.


Converting stumps to biomass feedstock is one way customers can turn waste to profit. For more information on the Titan Horizontal Grinding System, visit or email
