Taking Material Fines and Transforming them into Uniform Briquettes

Briquetting Beginnings

For over 100 years, roll press briquetting has been used to compact material fines and dust into uniform, densified briquettes. Widely adopted in industries like mining, metals, minerals, salts, and agriculture, this technology improves material handling, supports process efficiency, and reduces waste—making it a vital tool in modern industrial operations.

Roll press briquetting began in the early 1900s to address coal waste issues and gained commercial traction in the 1920s–30s where it expanded into a wide variety of industries and applications struggling with excess fines or dust.

How Briquetting Works:

If necessary, a binder is mixed in with the feed material for better material agglomeration.

The mixed material is fed to the roll briquetting machine which applies high pressure to fine particles, compressing them between two counter-rotating rolls. The rolls have cavities or pockets that shape the material into dense, durable briquettes suitable for various applications.

Depending on material handling requirements and end-use applications, the briquetting process can follow three distinct methods:

Cold Briquetting without Binder

Cold briquetting without a binder uses high pressure at ambient temperatures to compact feed materials into solid briquettes. This method is ideal for materials that naturally bond under pressure, providing a cost-effective and efficient solution.

Cold Briquetting with Binder

For materials that do not naturally bind together, binders are added during the process to retain the briquette’s shape and strength. This method ensures structural stability and is often used for materials requiring additional reinforcement.

Hot Briquetting

In hot briquetting, temperature plays a critical role. Feed materials are heated above ambient levels to increase malleability, allowing the material to form strong, compact briquettes under high pressure. This method is particularly useful for processing materials with low plasticity at room temperature.
