The raw materials of biomass briquetting machine usually need the following pretreatment steps before use:

Crushing treatment: Raw materials such as straw, sawdust, rice husk, etc. are crushed to ensure that their particle size is suitable for the processing requirements of briquetting machine.

Drying treatment: The moisture content of raw materials needs to be controlled within a certain range (usually 10%-15%), and too high or too low moisture will affect the briquetting quality and equipment operation. Screening treatment: Remove impurities in raw materials, such as stones and metal substances, to prevent damage to equipment.

Mixing treatment (optional): If necessary, different kinds of biomass materials can be mixed in a certain proportion to improve the briquetting performance or adjust the quality of finished products. Storage and treatment: The pretreated raw materials should be stored in a dry and ventilated place to avoid moisture or pollution.

These pretreatment steps can improve the working efficiency of biomass briquetting machine, prolong the service life of equipment and ensure the quality of final products.
