  • Pulverizing process
When the dimensions of the raw materials are larger than 50*50*10mm, a wood crusher must be used to crush the materials into smaller pieces. A hammer mill is then able to grind the material into segments less than 3mm in length.

  • Drying process
The appropriate moisture content for pelletizing is about 13%-15%. Our rotary drum dryer consists of a stove and a main dryer component which can cut down the moisture content from 60%-10%. Our stove is fueled by coal which saves the consumption of electricity.

  • Pelletizing process
The ring die pellet mill provided by KMEC can make pellets continuously in most adverse conditions. The key features of our design are high quality, durability and low maintenance costs. Considering its functionality, our primary components adopt alloyed steel.

  • Cooling process
After pelletizing process, the temperature of biomass pellets is very high about 80℃. The pellets’ moisture content is typically about 15%. With the help of counterflow cooler, moisture content of wood pellets can be reduced to 3-4% simultaneously decreasing the temperature.

  • Bagging process
After cooling, the pellets must be packed with plastic bag in order to avoid humid and break. So the pellet packing machine is necessary for pellets. It is better to store and transport. The pellet packing machine includes two types: semi-auto packing machine and auto-sealing packing machine. The clients can select proper pellet packing machine depending on your practical needs.
