Biomass Fuel and Energy
Grinding forestry residue, sawmill waste, clean waste wood and agricultural residue into boiler fuel and pellet feedstock.
The WeiDong WDE1690M is an electric skid-mounted horizontal grinder for permanent or semi-permanent wood-waste and biomass processing lines. It combines the larger 1690 controlled-infeed platform with a project-specific motor and electrical package.

The WDE1690M combines a controlled horizontal infeed system with WeiDong’s 1690-series grinding platform. Its skid-mount configuration is designed for fixed or semi-fixed processing facilities. The listed 360 kW Electric power configuration supports the main grinding system, while hydraulic auxiliary systems control functions such as feeding and discharge. The 1620 x 640 mm inlet is designed for long wood, branches, forestry residue, and prepared biomass feedstock. Actual throughput and finished particle size depend on feed material, moisture, contamination, rotor selection, screen configuration, and feeding conditions. Final transport, electrical, emissions, and public-road requirements are confirmed for each order and destination market.
Choose WDE1690M when mobility is unnecessary and the 1690 grinder will become part of a powered production line. The skid format simplifies plant integration compared with a wheeled or crawler undercarriage.
Performance note: Capacity and final particle size vary with feedstock type, moisture, contamination, rotor, screen and feeding conditions. Confirm the final configuration through material testing and the project specification.
Best suited to facilities with a stable industrial power supply and planned electrical infrastructure.
Skid-mounted configuration for fixed or semi-fixed processing plants.
The infeed system presents material to the grinding chamber in a controlled flow.
Electric Main Drive + Hydraulic Auxiliary Systems. Final component scope is confirmed in the project specification.

Grinding forestry residue, sawmill waste, clean waste wood and agricultural residue into boiler fuel and pellet feedstock.

Grinding logging slash, whole trees and forestry residue at the landing or roadside into transportable biomass.

Recovering C&D timber, formwork, pallets and crates as fuel or recycled-wood fractions, with metal separation planned in.

Turning slabs, edgings, bark, offcuts and mill residue into boiler fuel, mulch or board feedstock.
Provide voltage, frequency, available capacity, transformer information, preferred starter or VFD arrangement and site cable requirements.
Yes. Feed, discharge, magnet and downstream interfaces can be reviewed as part of the final plant layout.
A single capacity value is not stated until the material and final configuration are confirmed. Actual throughput depends on feedstock, moisture, contamination, rotor, screen and feeding conditions.
Provide material photos or video, maximum feed size, moisture and contamination, required throughput, target output, site conditions, mobility needs and the destination electrical supply where applicable.
