Horizontal Grinders HG400

Vermeer HG400 Industrial Horizontal Grinder Technical Specifications
Architectural Engineering & Core Performance Mechanics
The Vermeer HG400 is a highly versatile, compact industrial horizontal grinder designed for processing organic wood waste, pallets, compost, construction debris, and medium-diameter logs into highly valuable end-products. Engine power is derived from a robust 4-cylinder Cummins QSF3.8-C130 diesel engine delivering 130 hp, operating via a fully automated hydraulic clutch setup that self-engages based on engine RPM, thereby eliminating the need for periodic manual mechanical adjustments. The primary infeed framework includes an expansive steel chain conveyor floor accompanied by large flared walls that facilitate smooth, hassle-free material feeding. An adjustable infeed tailgate can be lowered to increase the table length for processing long timbers. Active material downforce and feeding pull are generated by a heavy steel upper feed roller fitted with 15 aggressive gripping teeth and driven by dual independent hydraulic motors, producing a downward compression force of 10 MPa. Processing fragmentation is handled by a 905 lb (410.5 kg) duplex cutting drum with a large 31.3-inch diameter spinning at 1170 RPM, generating a blistering knife-tip speed of 9,048 ft/min (2757.8 m/min) to guarantee consistent material output sizing. The machine features an innovative sideload dual-screen configuration, allowing a single operator to swap square-mesh sizing screens from the side of the machine in minimal time. Electronic control architecture is built around a premium Danfoss Plus+1 micro-controller system offering 4 distinct feed speeds, complemented by a long-range wireless radio remote control operating up to 98.4 feet (30 meters). For exceptional transport flexibility, the unit incorporates a 7-foot folding discharge conveyor, allowing the entire grinder to fit securely inside standard shipping containers.
