From Factory To Factory: Lessons Learned From Pellet Production
Jan 10, 2019

We have talented and experienced engineers of many years experience and they have given our company a quick grasp of the technical aspects of the pellet plant and other equipment in the pellet plant.

As you know, the pellet process is conceptually simple: dry and ground sawdust is compressed at high pressures and temperatures to ensure adequate density. However, the efficient and reliable operation of the pellet machine requires considerable skill and experience, and sometimes requires a large amount of improvisation. As a result, the learning curve of the pellet business is long and steep, especially when you see the difference between a separate setting and a mixture of raw materials.

North America and Europe account for 67% of global pellet production, so it is worth knowing about these two markets. I have found some differences from several visits to pellet factories in Europe and North America.


In Europe, almost all pellet mills use starch as a binder, and most pellets are produced according to EN Plus standards for residential heating. In the United States and Canada, industrial pellets are exported to most markets, with the largest share being industrial heating. For example, the Drax power plant in the UK uses hardwood and softwood or a mixture of the two to produce pellets that need to be processed and peeled, but impurities It is still inevitable, so the wear on the equipment is much higher. Therefore, cup and tapered bearings in North America are very popular because they are serviceable compared to box bearings.

In addition, there is a seat release space from the cup and cone system that allows more surface areas to contact the cup, allowing for more efficient dispersion of the load. In addition to the setup, another major difference is that temperature monitoring during operation is usually not present, which causes the operator to turn a blind eye to the condition of the roller, which increases the risk of fire. This prompted us to develop an improved temperature monitoring system to track the temperature of each roller.

On two continents, the trend is to renovate internal drums to track quality and reduce maintenance costs. The best way to retread the rollers is to match the temperature to prevent assembly damage. The housing can be heated by gradual warming using an induction heater or oven. The ideal temperature for the housing is approximately 260 degrees Fahrenheit (127 degrees Celsius) and the ideal temperature for the bearing is 155 degrees Fahrenheit (68 degrees Celsius). Bearings should slide easily into the housing.
