Wood pellet packing machine

Wood pellet packing machine, also known as pellet bagging machine, is used to weigh and pack wood pellets automatically. It can realize quantitative packing for granulate and powdery materials who have good fluidity, such as plastic pellets, rubber particles, fertilizer particles, chemical particles, grains, etc. The packing bags can be made of plastic, woven, kraft, sack, paper-plastic compound.

The automatic packing machine is a common equipment in large and medium sized pellet production line. It can accomplish automatic weighing, packing, conveying and sewing. For large-scale production, e.g. 5t/h or more, you’d better use an automatic wood pellet packing machine to save your labor and time.

Specifications of a wood pellet packing machine

The wood pellet packing machine is composed of a storage bin, weighing system, conveyor, packing system and an intelligent controller.

  • The storage bin serves to take over the materials and store them temporarily.
  • The weighing system can weigh specific quantity of materials.
  • The intelligent controller ensure the packing machine works automatically and accurately.
  • The conveyor serves to transmit the pellet bags from the weighing system to the sewing system. It is 3 meters long.
  • The wood pellet packing machine can pack 200-300 bags per hour. The weight of the bags ranges from 5kg to 50kg.

How does a wood pellet packing machine work

First, you need place the bag to the filling spout manually. Then, press the button to start. The pellet materials will accumulate in the hopper and be fed into the bags through the filling spout. The filling speed is controlled by a frequency converter. When the bag is filled up with pellets, the bag clamping device will open and the bag will be conveyed to the sewing device.

Roughly, the packing process can be divided as the following.

Manual bag placing → Automatic filling → Automatic weighing → Automatic conveying → Automatic sewing → next process
