pellet mill production line

A complete pellet mill production line, from raw material processing to final biomass pellet packing, it mainly include Crushing, Drying, Pelletizing, Cooling and Packing. The whole process is highly automatically controlled.

(1) Wood pellet mill: pulverizing system
When the dimensions of the wooden raw material are greater than 50*50*10 mm (L*W*H), a wood chipper must be used to reduce the stock into smaller pieces. A hammer mill (crusher) is then able grind the material into segments less than 3 mm in length.

(2) Drying System
The best moisture content for pelletization is about 13-15%. Our rotary dryer is comprised of a stove and main dryer component which can reduce the moisture from 60% to 10%. Our stove is fueled by coal, which saves on the consumption of electricity.

(3) Pelletizing System
The heavy-duty gearbox construction of our machines can produce continuously in most adverse conditions. The key achievements in our design are high performance, durability and low maintenance costs. Our primary components are comprised of alloyed steel for strength and functionability, with the die made of stainless steel. Available capacities range from 200 kg to 3 tons per hour.

(4) Cooling/Sieving/Bagging System
After the pelletization process, the temperature of the wood pellets is between 60-80 degrees Celsius. The pellets' moisture content is typically about 15%. With the use of a cooler the moisture of the pellets is reduced to 3-4% while simultaneously decreasing the temperature.
