Briquetting is the process of compressing materials such as coal, iron ore and charcoal into a solid mass. This process can be used to create a variety of shapes, sizes and densities, depending on the material and the desired application.The Briquetting process requires several steps including, grinding, sizing and compaction.
The grinding process usually begins by feeding raw materials into a rotating drum that is lined with steel bars or hammer-like blades. This breaks down the material until it has the desired texture and consistency. Depending on the end product desired, the material may then go through a sizing and grinding process that can involve additional crushing machines or even a third stage of grinding.
The next step in the process is compaction. This is done by placing the material into a pressing machine which applies high pressure to the raw material, forcing it into a shape desired. This compression can create a greater level of density and uniformity, as well as increased strength.
The compacted material is then cooled and finished. This may involve removal of any unwanted material and additives, such as possibly clumping agents, before it is ready for use. As with all processing, the desired outcome determines the optimal, specific process that is used.
The industrial application of briquetting is varied and widespread. As an example, breweries produce pellets of spent grains that can be used for livestock feed, as well as for composting and landfills. Companies also use briquetting for the creation of bricks, fuel and coal.
In more advanced uses of the briquetting process, technologies such as high-temperature reduction have been developed. This involves the extreme heating of materials to create a core of dense materials that can be shaped to a wide range of applications.
Briquetting can be used in a variety of industries and its application is constantly expanding. It is a cost-effective and efficient way to create shapes and sizes of materials, as well as to increase their strength and durability. As with any manufacturing process, the specific requirements of the application determine the most appropriate briquetting process.
