how to make straw pellets

Straw is an agricultural by-product, it makes up about half of the yield of cereal plants such as rice, corn and wheat etc. Compressing straw into pellets is a modern way to utilize straw resources. Straw pellets can be used as fuel, animal bedding and animal feeds etc. Considering the ready availability of raw materials, making straw pellets has strong economic benefits.

However, the straw contains many different compositions, so we put a step-by-step process here to guide people who have troubles with straw pellets making.


 

1. Pre-treatment
   The harvested straw usually mixed with many impurities such as little stones, dusts, metal debris and plastics etc. These impurities are very likely to cause damage to the pellet making machine, so they must be removed or screened out before you put the straw to a pellet mill.
2. Crushing
   Straw is in different sizes, it may not suit the pellet mill, so it should be crushed into chips or powder. In this process, you may need a hammer mill, but other ways like cutting and chopping can also help you get the materials in proper size.
3. Drying
   It is important that you dry the materials before put them into pellet mills, if the materials are too wet, they won’t be made into pellets successfully. The moisture should be controlled within a range of 10%-18%. In this process, you may need a airflow dryer or a drum dryer in your pellet line, these two kinds of dryer can all help you control the moisture of raw materials precisely.
4. Adjusting
   GEMCO small pellet mill can make pellets perfectly without any additives. But if you use additives like adhesive properly, you can control the hardness of straw, which can increase the yield and quality of pellets. Pelletizing
   Put the raw materials into the feeder house of your pellet mill and start to make your own pellets!
