Briquettes can be difficult to form due to two main factors:

• Material size and moisture content

  Ensure that both the material size and moisture content are properly controlled. The temperature of the heater on the briquette machine should also be set correctly. Preheating the forming area in the briquette press before feeding the material can help. High temperatures soften the feedstock, making it easier to compact and bind the particles together.

• Tolerance clearance

  The tolerance clearance between the screw rod (also known as the spiral spindle) and the sleeve plays a significant role in the briquette formation process. Different materials require different clearances. Ensuring that the tolerance is consistently accurate is critical to achieving well-formed briquettes.

The tolerance clearance refers to the gap between the screw rod (spiral spindle) and the sleeve in mechanical briquetting machines. This clearance allows the material to be compacted under high temperature and pressure. As the material moves between the screw rod and the sleeve, it is squeezed into the desired shape. The precision of this clearance is crucial for producing high-quality briquettes.

Biomass briquettes and pellets, made from agricultural and forestry waste, offer a high-density, high-thermal-value renewable fuel. They reduce air pollution and carbon dioxide emissions, serving as a sustainable alternative to fossil fuels like natural gas and coal. Applications include domestic fireplaces, small to medium-sized biomass boilers, and industrial power and heat plants.

A coke briquette machine is a compression machine that transforms raw materials into high-density briquettes. Utilizing high pressure, it compacts loose materials together. These machines process not only coke powder but also other powders like coal and charcoal.

The briquette size and quality depend on the compression ratio of the forming mold, not the size of the briquettes themselves.
