1690 Electric Crawler Horizontal Grinder WDE1690C

The WDE1690C 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 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.

Why choose the WDE1690C

Choose WDE1690C when electric production and crawler access are both required. The site must support the incoming power and cable-management system needed for safe repositioning.

Recommended applications

• Powered yards with uneven operating surfaces
• Large feed dimensions requiring controlled horizontal infeed
• Short-distance repositioning inside a defined electrical area

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 machine must work beyond a practical cable area
• Prepared surfaces make the wheeled configuration simpler
• No reliable industrial power is available

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
