Both briquetting and compaction granulation are types of pressure agglomeration, whereby a material is put under extreme pressure, causing it to bind to itself. While these two methods of agglomeration are effective for many materials, they are not an option for all materials. Some materials simply won’t bind to themselves under pressure, while others may agglomerate, but not effectively.
As a general rule, sawdust, for example, cannot be briquetted due to the “rebound” effect. This means that as soon as the briquette exits the press, it springs back to its original form and loses any resemblance to a briquette. On the other hand, pressure agglomeration is an effective, cost-efficient option for salts like potash, for example.
When looking to agglomerate a material, feasibility testing is always recommended. Feasibility testing can not only determine if your specific material will agglomerate, but also what the best method of agglomeration will be. Agglomeration feasibility testing in the FEECO Lab offers a host of valuable information for those interested in both pressure and non-pressure agglomeration.
