Biomass drying granulation production line is one of the main equipments of our company. So far we have created many successful cases. Recently, the wood chips pellet production line equipment ordered by customers in Bosnia and Herzegovina has also been successfully delivered.

  The main working steps of wood chip drying granulation production line:

  1. Drying process: Calculate the amount of evaporation based on the feed moisture provided by the customer and the moisture required to produce the pellets, so as to select the diameter and length of the drum and the model of the hot air stove. Commonly used dryers include three-cylinder dryers, single-cylinder dryers, and air-flow dryers. Among them, the drum dryer is recognized by our customers as the most common and most cost-effective dryer. In this section, the wood chips with a moisture content of 20-60% are dried to 12-18%, so that the next step of granulation is carried out.

  2. Granulation process: The wood chips are processed into granules with a diameter of 6mm, 8mm, 10mm, and 12mm. The wood pellet machine is the core part of the entire production line. Before granulation, iron blocks and stones need to be sorted out to prevent damage to the ring mold and pressure roller of the pellet machine, thereby extending the service life of the vulnerable parts of the pellet machine. The press rollers are made of wear-resistant alloy material, The working life of wearing parts is several times of similar products. Transmission structure can realize the automatic filtering process of grease.
