Drum Wood Chipper

It is designed for industrial wood chipping in energy, mining, biomass power plants, boiler and pellet plants, and large-scale wood-waste processing (wood logs, pallets, branches, bamboo, building templates, etc.).

Common models include YGX216, YGX218 and YGX2113. Capacities vary by model: YGX216 ~4–6 t/h, YGX218 ~8–15 t/h, YGX2113 ~15–30 t/h. Inlet sizes also differ by model (23×50 cm, 30×68 cm, 45×70 cm respectively).

The composite rating lists the main chipping motor plus auxiliary motors (for feeding rollers, conveyors, blowers, etc.). For example, the first number is typically the main rotor motor (55 kW) and the smaller values are the auxiliary motors. Exact motor breakdown is supplied in the technical documentation for each model.

Maximum recommended feeding diameter is approximately 18 cm for typical operation (verify by model and material). Inlet dimensions are model-dependent: 23×50 cm (YGX216), 30×68 cm (YGX218) and 45×70 cm (YGX2113), allowing large branches and logs to be fed.

Finished chip size is approximately 3×3×3 cm (model and configuration dependent). Chip size can be influenced by knife type, screen (if fitted) and rotor configuration, so it can be adjusted to meet specific downstream requirements.

Rotary knife options include 2, 4 or 6 knives combined with one fixed knife (depending on model). Different rotary knife counts change throughput and chip quality; consult the supplier to select the best configuration for your material and capacity needs.

The machine requires an industrial three-phase electrical supply sized to match the model's total motor power. Specific voltage/frequency and starting equipment (soft starter/VFD) should be confirmed with the supplier. A proper concrete foundation, space for feed and discharge conveyors, and safe access for maintenance are also required.

Standard safety measures include guarded rotor and knife housings, emergency stop controls, feed-roller protections and mechanical covers. Safe operation also requires trained operators, lockout/tagout procedures for maintenance and use of recommended PPE.

Daily checks (visual inspection, clear blockages), routine lubrication of bearings and moving parts, periodic inspection and sharpening/replacement of knives and bearings. Frequency depends on feedstock abrasiveness and throughput — heavy use may require knife attention weekly to monthly. Follow the manufacturer maintenance schedule for intervals and service actions.

The chipper uses HRB standard bearings and high-quality motors (Siemens-type in the specification) to reduce downtime and extend service life. Critical components are chosen for heavy-duty industrial use.

A 1-year warranty covers core components and overall machine performance. ROTEXMASTER provides an outgoing machinery test report and inspection video with each unit. Engineers are available for overseas service and commissioning support as needed.

Spare parts (knives, bearings, belts, etc.) are available from ROTEXMASTER. It’s recommended to keep a small inventory of high-wear parts (knives, bearings). Contact the sales or service team for lead times and international shipping options.

The machine is designed for efficient chipping with low noise and no direct pollution from mechanical operation; however, actual noise levels depend on installation, load and environment. Additional acoustic enclosures or barriers may be recommended for noise-sensitive sites.

ROTEXMASTER provides pre-delivery testing, an outgoing inspection video and machinery test report. On-site installation and commissioning support are available — engineers can be dispatched overseas to assist with setup, alignment, electrical hookup and operator training.
