Preparing the mixture of quality sawdust briquette and binders involves several steps to ensure a homogeneous and workable mixture. Here’s a general guideline:

  • Select the binders: Depending on the application, choose the appropriate binders that will provide the desired properties to the final product. Common binders used with sawdust include adhesives, resins, or other additives designed to improve cohesion and strength.
  • Measure the ingredients: Determine the appropriate ratio of sawdust to binders based on the desired consistency and properties of the mixture. This ratio can vary depending on the specific application and the type of binders used. Follow the manufacturer’s guidelines for the binders, if available.
  • Mixing process:

a. Dry mixing: In a suitable container or mixing vessel, add the measured amount of sawdust. Gradually introduce the binders into the sawdust while continuously mixing. Use a mechanical mixer or other appropriate tools, such as a paddle or a trowel, to ensure thorough and uniform distribution of the binders.

b. Add water gradually: If water is required to achieve the proper consistency, add it gradually to the mixture. Be cautious not to add excessive water that may lead to saturation or compromise the performance of the final product. The amount of water needed will depend on the specific binders and the desired consistency of the mixture.

c. Mixing until homogeneity: Continue mixing the sawdust, binders, and water until a homogeneous mixture is achieved. This means that the components are evenly distributed, and there are no visible clumps or dry spots. The mixture should have a consistent texture throughout.

  • Testing and adjustment: Once the initial mixture is prepared, perform tests to assess its workability and properties. This can include checking the consistency, adhesion, and any other specific factors relevant to the application. If necessary, make adjustments by adding more binders or water, following the guidelines for the desired outcome.
  • Storage and curing: Depending on the application and binders used, the mixture may require a curing or drying period. Follow the recommended curing time and conditions specified by the binders’ manufacturer to achieve the desired strength and properties of the final product.

Shaping and Compacting

Choosing the right briquette press or mold:

  • Select a briquette press or mold that is suitable for the desired shape and size of the briquettes.
  • Consider the material of the press or mold to ensure it is durable and can withstand the pressure applied during compaction.
  • Choose a press or mold that allows for easy removal of the formed briquettes.

Filling the press or mold with the mixture:

  • Take a portion of the prepared mixture and place it into the briquette press or mold.
  • Ensure that the mixture is evenly distributed and fills the entire cavity of the press or mold.
  • Use a tamper or any suitable tool to compact the mixture slightly and remove any air pockets.
  • Continue adding the mixture and compacting until the press or mold is filled to the desired level.

Applying appropriate pressure for compaction:

  • The pressure applied during compaction will depend on the specific requirements and the type of briquette press or mold being used.
  • If using a manual press, exert gradual and consistent force on the lever or handle to compress the mixture. Apply enough pressure to achieve proper compaction without causing the mixture to disintegrate.
  • For mechanical or hydraulic presses, follow the manufacturer’s instructions to set the appropriate pressure levels. Ensure the pressure is applied evenly and consistently.

Removing the formed briquettes:

  • Once the compaction process is complete, release the pressure from the press or mold.
  • If using a mold, gently tap or shake it to loosen the briquettes and facilitate their removal.
  • Carefully remove the briquettes from the press or mold, taking care not to damage their shape.

Drying and Curing
