In the process of biomass briquetting by biomass briquetting machine, raw material pretreatment is a key link, and its function is mainly reflected in the following aspects:

Improving Molding Quality

Through crushing and drying, the raw materials achieve uniform particle size and suitable moisture content (typically controlled between 8% and 15%). This prevents the briquettes from becoming loose and easily broken due to excessively large particle size or high moisture content, ensuring that the briquettes meet density and strength standards.

Enhancing Production Efficiency

Pretreated raw materials have better flowability, allowing them to enter the biomass briquette machine more smoothly, reducing blockages and material jamming, ensuring continuous and stable equipment operation, and increasing output per unit time.

Reduced Equipment Wear

Removing impurities (such as stones and metal fragments) from raw materials reduces wear on core components of biomass briquette machine, such as rollers and molds, extending equipment lifespan and lowering maintenance costs.

Optimized Combustion Performance

Pretreatment ensures more uniform mixing of raw materials, resulting in a denser internal structure of the briquettes. This leads to higher calorific value and more complete combustion, reducing smoke and harmful gas emissions.

Expanded Raw Material Applicability

Pretreatment allows for the conversion of various types and forms of biomass raw materials, such as straw, sawdust, and rice husks, into uniform materials suitable for briquetting, improving resource utilization.

In short, raw material pretreatment is a fundamental step in ensuring the quality, efficiency, and economy of biomass briquettes, and directly affects the market competitiveness and application value of the final product.
