1690 Crawler Horizontal Grinder WD1690C

The WD1690C combines a controlled horizontal infeed system with WeiDong’s 1690-series grinding platform. Its crawler configuration is designed for uneven job sites and frequent on-site repositioning. 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 WD1690C

Choose WD1690C when the larger 1690 grinding system and crawler access are both required. It is heavier than WD1690W and prioritizes job-site mobility over convenient road transfer.

Recommended applications

• Large forestry projects on uneven or unprepared ground
• Frequent repositioning within the operating site
• Higher feed dimensions requiring the 1690 platform

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

• Prepared surfaces make the 23-tonne wheeled model more practical
• The smaller 1380 crawler can meet production requirements
• Bulky irregular roots make tub feeding preferable

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
