2017-1-12  For these reasons many differing types of equipment have been developed to achieve these aims aiming to make, larger entities from powders, in which the individual primary particle are still visible, this process when carried out in a mixing device is usually described as granulation. Granulation and agglomeration processes tend to use a

Bed Agglomeration Characteristics and Mechanisms

2019-5-24  Controlled agglomeration tests, using six representative biomass fuels (bark, Lucerne, reed canary grass, bagasse, olive flesh, and cane trash) were performed in a bench-scale fluidized bed (5 kW) during both gasification and combustion conditions. The resulting bed materials were analyzed using scanning electron microscopy/energy-dispersive spectroscopy (SEM/EDS), and chemical equilibrium
