The energy consumption of a wood pellet production line can vary depending on several factors, such as the size of the production line, the type of raw materials used, and the efficiency of the equipment. However, some general estimates can be made.

1. Drying: The raw china Wood Hammer Mill Manufacturers  materials must be dried to a suitable moisture content for pelletization, which can require a significant amount of energy. The energy consumption for drying can range from 0.5 to 1.5 kWh per kilogram of raw material.
2. Grinding: The raw materials must be ground into smaller particles before they can be pelletized. The energy consumption for grinding can range from 0.1 to 0.3 kWh per kilogram of raw material.
3. Pelleting: The actual pelletization process requires energy to compress the ground material into pellets. The energy consumption for pelleting can range from 0.2 to 0.5 kWh per kilogram of raw material.
4. Cooling and Screening: The finished pellets must be cooled and screened to remove any oversized or undersized pellets. The energy consumption for cooling and screening can range from 0.1 to 0.2 kWh per kilogram of raw material.

Overall, the energy consumption of a wood pellet production line can range from 0.9 to 2.5 kWh per kilogram of raw material. However, it's important to note that these are rough estimates and the actual energy consumption can vary depending on the specific production line and operating conditions. Additionally, the energy consumption can be reduced by using energy-efficient equipment and optimizing the production process.
