1690 Road Wheeled Horizontal Grinder WD1690W

The WD1690W combines a controlled horizontal infeed system with WeiDong’s 1690-series grinding platform. Its road wheeled (self-propelled) configuration is designed for mobile operations and convenient site transfer. The listed 408 kW / 550HP 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.

Why choose the WD1690W

Choose WD1690W when the larger 1690 processing platform is required and work takes place mainly on prepared surfaces. It combines diesel independence with a 23-tonne road-wheeled configuration.

Recommended applications

• Larger feed dimensions and higher production requirements
• Prepared sites requiring road-wheeled transfer
• Forestry, sawmill and biomass operations using controlled infeed

Recommended feed materials

• Long wood and large branches
• Forestry residue
• Sawmill and pallet waste after contamination review
• Prepared biomass feedstock

Materials to confirm before ordering

• Large irregular stumps better suited to tub feeding
• Construction wood containing metal
• Material with heavy soil or stone contamination

When another configuration fits better

• The smaller 1380 platform meets the project requirement
• Uneven ground requires the 25-tonne crawler configuration
• A fixed powered facility is better suited to electric skid-mount

Options confirmed for each project

• Rotor and screen selected for the feedstock
• Feed conveyor and discharge arrangement
• Magnetic separation where metal contamination is expected
• Remote control and project-specific safety equipment
• Engine, motor and electrical brands subject to configuration

What changes actual capacity

• Feed material type, density and hardness
• Maximum piece size and feeding consistency
• Moisture content
• Soil, metal, stone and other contamination
• Rotor, cutter or hammer configuration
• Screen opening and required output size
• Operator practice and downstream material handling

Information needed for a quotation

1. Material description, photos or a working video
2. Maximum feed dimensions and typical piece size
3. Moisture level and known contamination
4. Required hourly throughput
5. Target output size and downstream use
6. Ground conditions and required mobility
