Applications
Forestry and Logging Residue
WeiDong horizontal grinders and tub grinders turn logging slash, whole trees, tops, branches and forestry residue into transportable biomass at the landing. The WD1690 horizontal grinder has a 1,620 × 640 mm controlled infeed and 408 kW; the 3600-series tub grinders handle bulky residue at a typical 25–40 t/h.
What this application demands
Long material
Whole trees and long slash feed consistently through a horizontal grinder’s conveyor and feed roller.
Remote landings
Diesel crawler or wheeled chassis work away from grid power and move between landings.
Truck loading
Discharge conveyor height and reach are matched to the trucks or containers used for haulage.
Service in the field
Wear inspection, spare cutters and remote support keep a remote operation running.
Forestry residue is worth more when it leaves the forest as a dense, uniform product. The right grinder depends on whether the feed is long stems, mixed slash or bulky stumps, and on how far the machine must move.

Frequently asked questions
What is the best grinder for whole trees?
A horizontal grinder such as the WD1690C or WD1690W, because its controlled infeed handles long stems. Confirm the largest stem diameter against the 1,620 × 640 mm inlet.
Can WeiDong grinders work at remote forest sites?
Yes. Diesel models on crawler or wheeled chassis operate without grid power; the engine brand can be chosen to match local service support.
