What is Agglomeration? Glossary of Powder Mixing

Sintering, also known as frittage, is a thermal agglomeration process during which the atoms within the materials diffuse and form bridges across distinct particles, joining them together. Sintering involves heating products without melting them, and as such is particularly well-suited for materials with very high melting points.

What Is Agglomeration? powderbulksolids

27/02/2008 Three methods enlarge particulate solids through agglomeration: tumble/growth agglomeration, pressure agglomeration, and agglomeration using heat (sintering). In tumble/growth agglomeration, the adhesion of particles to one another is controlled by the competition between volume-related separation and surface-related adhesion forces.

01/01/2005 The pressure-drop sintering technique can predict the agglomeration propensity for coals. Samples with a sintering temperature lower than the operating temperature of the PFBC showed agglomeration. The laboratory ash can be a good representative of the PFBC ash when studying agglomeration and defluidisation.

Iron Ore Agglomeration Processes and their Historical

28/12/2015 The origin of sintering process goes back to 1887 when F. Haberlein and T. Huntington of England invented the process of agglomeration for sintering of sulphide ores. In this process, the sintering was carried with the sintering bed being blown with air from bottom upwards. The process was also known as up-draft sintering process.
